Chapter 1. Introduction.

Laser-engraving machine - a high-tech product that combines a computer, laser technology, automatic control and optics in one machine. These machines are widely used in many areas: advertising, cutting of various materials, electronics, applied art, ritual services, in light industry, in the production of souvenirs, etc.

Price list on laser machines.

The main advantages of laser-engraving machines: an advanced laser is used, which replaces the traditional mechanical engraver.

If you compare these machines with mechanical engraving machines, then laser engraving machines have many advantages, here are the main of them:

1. Capture devices are not required, the working material is placed on the table surface, which is convenient and efficient.

2. There is no special requirements for the hardness of the material, thus, the range of their application increases.

3. High accuracy of engraving, plastic, plywood, tree, as well as on stone.

4. When applying a CNC laser machine, the performance efficiency increases at least 2 times.

5. Modern and convenient control panel: In the laser-engraving machine, a modern keyboard is used reliable and convenient in operation, combined with a digital control system. We also use stepper motors that provide faster and high work accuracy.

6. The operational interface provides ease of work.

7. Fully closed case makes the car more secure and comfortable.

The scope of laser-engraving machines: the laser beam of the machine is able to cut and engrave all non-metallic materials, and when using special means (metal engraving paste) it is possible to engrave metals. The accuracy of the positioning of the laser head of the machine is 0.015 mm, due to which the very high accuracy of engraving and cutting is achieved. Stepper motors used in the car provide high speed and greater performance. Depending on the material during their cutting and engraving, complex forms of exclusive design are obtained. The multifunctionality of the computer program for the machine allows you to get ready-made products, simultaneously cutting out and engraving them.

One of the most popular materials for laser cutting and engraving is organic glass. When it cuts the edge, the mirror is obtained, the end is slightly melted. When docking the obtained billets, there is practically no optical clearance. The scope of products from organic glass is limited only by fantasy. This is mainly advertising products and design elements and interior.

The following material is the material - wood and its derivatives. Cutting material can be carried out on a complex circuit with a sufficiently high speed of up to 3 m / min. The products obtained are used for the manufacture of furniture, complex parquets, souvenir products, and much more.

For the manufacture of seals and stamps, machines with a small working field are ideal, such as HX-40A, HX-3040. Creating seals and stamps manually cannot provide high quality products. If the company is interested in improving productivity and product quality, it chooses advanced technology.

The laser-engraving machines presented by our company are ideal for these purposes. Fully computer control, advanced laser technology and digital control technology, all this solves low-quality problems and low efficiency in creating seals and stamps. Their small sizes do not require large areas for them for accommodation.

List of materials can be continued infinitely. Here is only its part: acrylic, anodized metal, cardboard, paper, coated metal, parenchy, cork, crystal, crystals, fabric, glass, quartz, laminated plastic, two-layer plastic, leather, marble, natural, artificial stone, melamine, Plastic film, rubber, wood, ceramics.

Chapter 3. Installation

Requirements for workplace.

Working conditions must comply with the requirements listed below. The lack of suitable working conditions can lead to improper operation of the equipment or damage.

The temperature indoors should be within 15-35 ° C. When the ambient temperature is higher than the maximum stipulated, the equipment will overheat, which will damage. At ambient temperature below the minimum provided, rapid wear of the guides, the junction of the mechanisms of moving the parts of the machine are possible.

Humidity should not exceed 80%. The formation of condensate will damage the electronic device and will threaten the safety of the operator.

The laser-engraving machine should operate at one power constant, avoid sharp voltage jumps. When voltage fluctuations, the device will not work correctly. If the voltage is too high, the power supply of the device will be completely damaged. To prevent fire and vehicle breakdowns due to high voltage, install voltage stabilizer for 2000w and more.

The laser-engraving machine must be well grounded. Poor grounding reduces the service life of the laser tube, and the discharge of high voltage is destroyed for the electrical circuit and is dangerous for life. Make sure the machine is well grounded so that static electricity does not harm a person!

Avoid closed close rooms and premises without ventilation. The workplace must be near the ventilation device.

The desktop must be near the engraving machine, the operator can add the necessary tools, materials, drawings, etc.

It is not allowed to work to persons who do not have experience with the apparatus or not passing instructing on commissioning work, otherwise the company is not responsible for the emercted breakdowns.

Installing the machine

The laser-engraving machine is located in a sealed wooden box, lift and lower it should be carefully. First, the machine must be released from all packaging materials. When installing a laser-engraving machine on all sides, it should remain at least 1 meter of free space. Ahead of the free space machine must be left more, for the convenience of working and moving the material. Put the machine on a solid and smooth surface. To achieve the best results, the laser-engraving machine must be appropriately aligned. Alignment should be made only after fixing the machine. After moving the machine to a new place requires a new alignment.

Next, you must install the exhaust device with the fastener, which is coming. The exhaust pipe from the car must be connected to the smoke, and from the smoke to the street. The maximum distance from the machine to the smoke 2m. From the smoke to the street 2 m. If the length of the chimney is more, then an additional smoke is necessary

The car needs to ground. The machine connects to the 220 V power supply power supply, it consumes 3000 W, so make sure that you are reliable than your wiring.

Attention:It is forbidden to ground the machine on the zero wire of the power grid!

The laser-engraving machine uses an external submersible pump feeding into a laser tube. It is necessary to prepare a container for coolant water. The height difference between the machine and the submersible pump should be no more than 0.5 meters. Cooling circulating water should be clean, without dust and dirt. The temperature of the cooling water must be within + 5- + 25 ° C.

When the insufficient amount of cooling water is detected in the container, it is necessary to turn off the machine and the pump that feeds the coolant. Add water and turn on the pump at least 30 minutes, or until the laser tube cools. If the water does not come, the laser tube fails. The pump must be completely immersed in water. At the entrance and outlet there should be no obstacles for free water circulation.

Connect the water and air pumps to the laser-engraving machine through the hoses, following the pointers by car. Wateroutlet - cooling fluid yield. This hose must be omitted into a container with coolant. Waterinlet - coolant inlet. This hose must be connected to the water pump. AIRINLET - This hose must be connected to the air compressor.

Laser tube - made of thin glass, very fragile and can easily break. It is necessary to check whether the laser tube is broken, and each component is installed freely in its place. Install the tube must be accurate enough to damage it. Remove the laser tube from the package. Open the back cover of the machine and set the laser tube to its regular place in the "C" mounting of the shaped type with the outlet to the reflective mirror using rubber gaskets (applied with fastener). Secure the laser tube without making great efforts to avoid her breakdown. Using fasteners and wrench (applied), connect the tube to the hoses for the coolant feed.

Sleep the red wire to the left tube contact, and the blue to the right. You can not heat the laser tube with a soldering iron for more than 3 seconds. Wires must be reliably soldered to the laser tube. Operating voltage 20 sq. M. Carefully insulate the contacts with the tape. After installation, the laser tube cannot rotate so as not to damage the connections.

Insert the power cable into the machine connector and install the fuse at its regular place.

Connect the USB cable to the computer and insert the electronic key to the USB port. Without an electronic key it is impossible to bring the car into action.

Install software software on a personal computer. Without installation of unique software, work on the machine is impossible. Be sure to close the machine at the end of the work to avoid deposit of dust on working parts!

Preparation for configuration.

Please make sure the following requirements are met:

1. Equipment is reliably;

2. The system is grounded;

3. In the water tank there is enough pure distilled water;

4. Water pump and compressor are included in the power supply;

5. Equipment is reliably connected to the network;

6. There should be no cooling water leakage;

7. The difference in heights from the pump to the laser tube should not be more than 0.5 meters;

8. The water temperature must be within 20 ° C;

9. The machine should stand on a solid smooth surface without vibration.

The operation of the laser machine is based on moving the laser beam along the changing trajectory. Laser tube, 3 mirrors, laser head and setting system set the trajectory of the laser motion. The result of engraving and cutting depends on the accuracy of the laser movement, so the operator must properly adjust the trajectory of the laser movement. The lens in the tube is fixed by the lens fastening bolt and lies with a convex part down. A tube on which air is supplied to the laser head, it is necessary for cooling the focusing lens. The air from the laser head goes through the nozzle.

Setting up the movement of the laser beam

Note!

When setting, you need to protect your eyes and ensure that parts of the body do not fall into the laser beam. Select the required laser power to avoid firewall fires. When the machine is running, it is forbidden to touch the power wire to avoid accident. Adjustment must be performed together. One sets up the path of passing the laser, the second clicks on the "Pulse" button. The laser used in this laser-engraving machine creates an invisible infrared beam. Before starting adjustment, make sure that there are no foreign objects on the path of the laser beam, and it is not directed towards people.

To configure lenses, a chipboard is used, when a laser beam leaves the trail. At the same time, it is necessary to reduce the power of the laser to avoid the fire of the wood chipboard. When setting up the laser beam, security measures must be followed. It must be remembered that the path of the laser beam should be inside the car, and do not go beyond its limits.

Setting up the movement of the laser beam:

A: Turn on the water pump or chiller and make sure that water circulation occurs, then turn on the laser machine.

B: Attach three wood chipboard (or cardboard circles) a little more than reflectors, before the first, second and third reflector.

C: Press the "Pulse" button which includes an operating group of a laser-engraving machine. A laser beam will occur (the laser power must be installed no more than 80%). Make sure that the stain left is in the center of the first reflector. If it is shifted to the side, it is necessary to center the laser tube in the "C" shaped mount. After the centering, remove the chipboard (dense cardboard circle) on the first reflector.

D: When the "Pulse" button is secondary, the laser will pass through the first reflector and will form a stain on the chipboard installed on the second reflector. In the event of not the beam in the center of the second reflective mirror, it is necessary to set up the first and second reflector using brass bolts located behind the lens rack so that they are on one horizontal line, and the laser beam hit the center of the second mirror. In the first mirror, adjust the angle of reflection, and in the second horizon. After setting, remove the chipboard (the circle of dense cardboard) in front of the second mirror.

E: The second and third mirror is configured similar to the first and second. It is necessary to configure the second mirror so that the laser beam falls into the middle of the wood-chipboard installed on the third mirror in all four corners of the laser machine.

F: The third mirror must be configured so that the beam falls into the center of the laser head lens. Through the angle adjustment of the reflector lenses. When the setup is completed, you must check the operation of the machine. During the configuration process, security measures must be followed, monitor the cooling connections of the laser tube.

Note!

1. When setting, it is necessary to protect your eyes and look at that parts of the body do not fall into the laser beam.

2. Select the required laser power to avoid the fire of wood and chipboard (circles of dense cardboard).

3. When the machine is running, it is forbidden to touch the power wire, to avoid accident.

4. The adjustment must be performed together. One sets up the path of passing the laser, the second clicks on the "Pulse" button.

Setting the focal length is to adjust the focal length. This affects the depth of the engraving and the thickness of the material during cutting.

Setting the focal length:

Place the working material (it is better to use organic glass) to the working surface of the machine. Loosen the screw on the laser head. By changing the distance from the laser head to the material and pressing the "Pulse" button. On the working material, stains of various depths and size are formed. It is necessary to set up so that the stain is the most deep and smaller in diameter. This will be the optimal focal length. In the future, when changing materials and maintain the laser head, the focal length will remain the same.

In laser equipment, three reflection mirrors are used and one focusing lens. Reflective mirrors are fixed on the first, second rack and laser head. The focusing lens is inside the laser head. Purity optics affects the depth and quality of engraving and cutting. It is necessary to mainly maintain their purity with special means for optics.

Mirrors are fastened with three screws with springs. Installation take care neatly, without touching the surfaces of the mirrors.

The focusing lens is installed inside the laser head using a ring and rubber gasket. To install it, it is necessary to remove the nozzle of the laser head. For installation, it is necessary to dismantle the nozzle. Gently insert a lens, not touching her surface and not scratching, then rubber gasket and fix with the help of a ring. When installing the lens, it is necessary to put down the convex side.

Chapter 4 Basic Operations.

The inclusion and operation of the machine.

Turn on the compressor. Turn the main power to press the switch on the rear panel of the machine. Turn the button « Emergency.Stop.» . Turn on the laser power using the key, and then wait 5 minutes to warm the laser. (Check whether the water in the plumbing hose is received). Turn the computer and connect it to the device using a USB cable. Determine the software, open the files for engraving, to install the current parameters. Promote the working material, find the zero point with a focusing mirror (t. e. Find the origin in the graphic file) using the appropriate keys on the control panel. Incline the engraving and cutting process (read the instructions carefully before work).

Note!

Before turning on the machine, it is necessary to check the condition of all connecting cables, the presence and water level of cooling. If the machine will work without coolant, then the laser tube can crack (burst) from overheating, thereby fail.

Stop the machine stopping the operation of the device, turn off the power of the laser machine, the ventilation system, the overall nutrition of the equipment, the air supply system.

Adjusting parameters.

Note!

Set the speed of movement and the power of the laser in accordance with the need and the specified technological parameters of the work, for high-quality performance.

Gently move the working material, and store the altitude of the working material specified by the focusing mirror.

Do not move heavy objects on the running surface, because This prevents the movement of a laser knife. Otherwise, the motor will be damaged and is given into disrepair.

When working, follow the correct operation of the pumping system.

Chapter 5. Maintenance and Care.

The net and neat environment is a pledge of high-quality engraving. How long the net engraving machine will remain depends on the type of the engraved material, the operation of the cooling system, the working conditions and the frequency of use of the machine. Dust accumulating in moving parts will lead to disorders in the process of engraving and premature wear of the moving system; Soot, accumulated on the optical mirror, will result in the destruction of the glass and its spoilement.

The mechanisms of the laser-engraving machine must be clean. The workplace must be clean and not contain dust.

Good manufacturing conditions are needed. The power supply must be stable. If the power fluctuations occur, the workplace must be equipped with a steady power supply (set voltage stabilizer). The machine should stand on a flat surface, its vibration is not allowed. It can not work in a wet environment.

The laser tube is heated, a sufficient amount of water is necessary for its cooling. Water should be clean, without dirt and dust. It is necessary to change the water every 3 months. The volume of water should be more than 40 liters. The water temperature should be from + 5 to +25 ° C.

Laser-engraving machine uses a laser tube that is filled with CO2 with gas. The volume of gas in the tube is enough for the pipe operation 100% for 1500 hours. The laser tube has 4 phases of work.

The first phase: the laser tube produces power more by 10% - 15% than declared. This phase lasts for 2 ~ 3 weeks.

Second phase: working phase. Laser tube issues declared power. This phase lasts approximately 1 ~ 2 months.

Third phase: power reduction phase. Since the tube is used quite a long time, its power gradually decreases. It is necessary to increase the power of the laser tube and reduce the speed. The duration of this phase is approximately 1 month.

Fourth phase: Phase of exhaustion. Replacing a laser tube.

With regular quality maintenance and execution of work rules, the service life of the laser tube can be increased.

Laser head guides must be clean. We regularly clean them with a cotton tampon dipped in alcohol and lubricate rubbing parts. Do not forget the tampon inside the machine.

Lens and reflective mirrors need to wipe a cotton swab dipped in a special solution daily. It is not allowed to find dust on the lens. If you detect damage to the lens or mirrors, they must be replaced.

In the machine everything should be dry, especially the mirror, laser tube and power switch.

If you notice moisture, immediately turn off the power and remove moisture.

To turn off the power supply of the machine first, turn off the toggle switch by car, then turn off the plug from the outlet.

Before turning on the machine, check the condition of all connecting cables, the presence and water level of cooling. If the machine will work without coolant, the laser tube can crack from overheating.

Reflective mirrors and laser head lens.

The surfaces of the departing mirrors and the laser head lenses are polished and covered with a thin layer of metal. The purity of their surface affects the laser power, so they must be clean, and it is necessary to regularly support it. Maintaining the purity of lenses increases their service life.

Water pump and blower

They are very easy to maintain. When you turn off the machine, you must be turned off. You must remove dust and dirt from them in a timely manner.

Failure to comply with these requirements can lead to the failure of the equipment or premature decrease in the working resource.

The laser machine and the computer must be correctly grounded.

Keep the laser car clean, especially two sliding rollers. Regularly lubricate the rubber machine with oil to prevent rust.

When working with the material, especially during its cutting, organic residues are accumulated on the working surface, which must be regularly deleted, because They will be burned and smoked when the laser is working.

Pay attention to the correct operating output operation, clean its surface.

Change water for cooling once every three months, measure the temperature of the inputs in the plumbing.

Maintaining a laser reflection system clean.

With long work, reflectors are polluted and must be cleaned every week. Please rub them using a special lens cleaning material, paper for lenses or adsorbing cotton. Carefully contact the lenses, do not damage their surface with sharp materials.

The lower surface of the focusing lenses in the focusing mirror can be contaminated with volatile substances from the working surface, sometimes dust. Cut the cleaning as needed.

Attention!

Before carrying out maintenance, the laser engraving machine must be disabled.

Purification steps:

1. Turn off the laser engraving machine, remove the plug from the outlet.

2. Open the casing of the machine, collect dust and waste with a dust collector.

3. Clean the window at the top of the housing, with a cotton fabric impregnated with soap water. It is made of a material that can differ in the influence of such a chemical solvent, as an alcohol or acetone, and therefore it cannot be purified by chemical solvents; For this, a special cleaning agent is applied. You can also apply a paper towel to avoid scratches.

4. To clean the moving system along the X axis, y, use a paper towel, apply lubricant to guides x, through special oils.

5. To clean the lattice, use a paper towel and a soft fabric, soapy water.

Cleaning optical mirrors:

Wash your hands before cleaning the optical glass. Do not touch the optical glass so as not to damage the protective film available on it. At the end of the work, you must, at least once, visually make sure that there is no soot or scratches on it.

Clean glass does not require washing. Too frequent washing can damage it!

Use cotton material impregnated with cleaning solution. Cotton material can only be used once. Repeat this operation until complete cleaning.

Temporary maintenance framework:

Maintenance time depends on the type of material engraved, engraving quality, engraving time and air absorbing system. The client can independently decide on the service life. Recommended checking or cleaning every 8 hours of operation. The client must set the service life in such a way as to extend the service life of the equipment, create more high quality products and reduce idle time. For maintenance will be spent about 5 minutes a day.

Chapter 7. Precautions.

Attention!

The difference between the outer temperature and the temperature of the cooling water should not exceed 5 ° C, otherwise it will lead to a condensate condensation on the mirror and damage.

Safety and precautions

The laser system should not remain unattended in working mode, since the laser beam can ignore the objects that are nearby, and therefore near the laser engraving machine should be a fire extinguisher.

The launch of the laser machine is prohibited until the exhaust gas fan includes.

Remove all foreign objects, materials, manuals, etc. From the working surface of the laser engraving machine to prevent the locking of its movement.

Ensure that there are no small items on the undercarriage. Every day, lubrication should be applied every day.

Make sure the characteristics and optical quality of the engravated materials, including:

Cooling requirements;

Speed \u200b\u200bsafe engraving.

Make sure the machine operator:

Passed a thorough appropriate training;

Learned safety requirements;

Mastered the engraving procedure;

Put on protective glasses and work clothes;

Water cooling system works;

Exhaust fan works.

Attention!

Do not wear clothes with wide sleeves and pockets, jewelry with stones, necklaces, rings, wristwatches, etc. Make sure that the line between the computer, the engraving machine and the control system is reliable, and the moving parts of the machine are not blocked.

Equipment requirements

Electricity:

Ground a laser installation

The execution of artistic engraving until recently was distributed only to specialized spheres of production and decorative design. Today, thanks to the development of the compact segment and at the same time, effective laser engravers to join this amazing occupation can anyone who does not leav from home. True, the variety of devices presented in the market may make it difficult to choose a novice. To purchase an optimal laser engraver for a home appropriate needs, you should have an idea of \u200b\u200bthe device of this device and the main operating parameters. Also navigate in a wide range of proposals will help a small review of manufacturers.

Varieties of engravers

First of all, the general direction of working with the device is determined. It is impractical to choose a model for a specific material, since in the future it may be necessary to expand the functionality, and the narrow-dimensional laser engraver will not be able to perform more complex tasks. Nevertheless, there is a basic separation of such devices depending on the nature of the processing of materials with different characteristics - these are gas models and solid-state.

That is, two varieties are distinguished by the source from which the laser beam is forming. Therefore, the quality of processing changes. Gas models are cheaper and at the same time cover a wide range of materials - we can say that this is a universal device for plastic, metal and other billets. In turn, solid vehicles differ in the special properties of radiation, but the range of materials in this case is extremely small. It can be said is a narrow-directed laser engraver for metal, although it is used in working with some types of plastics. The main advantage of this device is high processing accuracy on metal surfaces.

Power selection

If you plan to work with small details, it is better to access models that have a capacity of up to 40 W. Such devices differ optimal for miniature processing by a short-focus lens. For example, using such a model, you can make a print with a detailed drawing of small characters. But if a laser engraver is required for a stone, providing both cutting function, then the power should be higher. At a minimum, it is necessary to focus on devices with a strength potential of 60 W. Typically, such devices are supplied with medium-focus lenses by 2.5 inches.

It should be borne in mind that power is chosen not only according to the characteristics of the material being processed. It matters the spectrum of operations that are planned to be performed with it, as well as the thickness of the surface. In addition to the described power options, there are models for 20 W, and 120-cotton versions. So, if we plan to process a metal sheet with a thickness of more than 1 cm, then a table laser engraver is suitable with a power reserve from 100 W. Conversely, for a delicate operation with a pliable material, you should navigate to the lower limit of the force potential.

Additional features

If the choice fell on the productive apparatus, then the cooling system should also be provided. This supplement will provide a continuous workflow that is convenient for the user, and safely for the tool itself. The most technological versions are equipped with automatic focus. This, again, a desktop laser engraver, which will allow large volumes of working with maintaining high quality. However, the cost of such devices is significantly higher than simple models. For use at home, most convenient and practical devices are usually selected. Manufacturers are taken into account by endowing the internal filling of engravers with the possibility of programming. That is, the user remains only to ask a work program, and then the most complex pattern will be implemented. Thus, you can transfer the image from the photo to the metal sheet.

Laser mini engraver - what is the feature?

These are portable models that differ in small sizes, but at the same time have a wide functionality. This engraver class is quite common among lovers, so manufacturers strive to endow such models with new ergonomic properties. For example, a laser mini engraver can be used in conjunction with a laptop or computer. It is enough to connect the machine through the USB port and prepare for the transfer of a digital image to the working surface. However, it is here that one essential drawback lies. By virtue of the understandable causes of mini-devices have a small power, so they are not suitable for working with solid-state materials. But mini engraver is conveniently used in the design of glass, wooden, leather and plastic parts.

NEJE Model Reviews

One of the most famous manufacturers of household apparatus for engraving is NEJE. The line of this manufacturer is regularly updated with interesting versions. In particular, the inexpensive laser engraver of the JZ-5 series Users praise for the quality of the assembly and the ability to automatically position. The model works with different types of materials, including wood, plastic, glass and leather.

The characteristics of the model should include high processing speed, which is 10 times higher than the possibilities of competitors. Users and high accuracy. This unit is focused on miniature engraving - again, according to owners, the device can perform a distinguishable inscription even on the toothpick. If a laser engraver is required for plastic or wood, this option may be optimal. It can be purchased for 10 thousand rubles, which is not bad for a technological and functional device.

With the help of the table, you can determine the approximate ratio of the laser power and the area of \u200b\u200bthe working field. However, these are not final options, you can choose the necessary you.

Laser engraving machine performance

Can a laser engraving device work non-stop for a long time? Maybe not any. From the small apparatuses, the VENO 530 model with a small working field will successfully cope with this. However, any model needs to constantly cool the laser tube, the water temperature in which should not exceed 25 ° C.

For this, there is a specialized device called Chiller, which prevents overheating of laser engraving devices, extended their life.

But even in this case, no one has canceled the service life of the laser tube itself. What he is more, respectively - better. With us you can purchase laser tubes with a service life of 1,500 to 10,000 hours.

Metal art engraving is quite rare and dear decor. Create such a decoration can be manually or a special metal engraving typewriter. Most often engraved items exclusive, and look very presentable.

Metal engraving is the process of applying an image to a metal base. Such a process is carried out at home in the presence of the necessary tools or a special engraving machine. Engraving is carried out in several ways, using various equipment. This process does not represent a special difficulty, so we will perform even in simple conditions. Perform on metal parts of weapons, paints, wedding rings, clock, gift dishes and other products made of metal.

Metal products decorating methods

When performing engraving on metal use various techniques. All their aggregate is divided into two ways: manual and mechanical engraving.

With a manual method, the master inflicts a drawing or an inscription with a special tool. The quality of engraving depends on the skill of the wizard. For engraving on a complex surface, it is necessary to use this way - the technique here will not cope.

It is performed using an engraving machine, computer and master's skills. The quality of the product in this case depends on the quality of equipment and software. Image accuracy is higher than when manual method.

Necessary equipment

When compliance with technology, you can achieve an in-depth or, on the contrary, a convex image - depending on the idea.

For application of mechanical engraving, special machines are applied - engravers. They work from the power grid and help to apply a high-quality image on the surface of polished metal. Work on the basis of the impact method of engraving, performing polishing and surface stripping. Possessing a convenient size, engravers are simple and easy to use.

The principle of operation of the engraving machine is to rotate the moving element, which is driven by the electric motor through the gearbox. As a rule, such machines have a small capacity - only 200 W, but it is enough for engraving at home. In the package of some machines included fasteners, and therefore, fixing engraver on the table, the master rotates the part with both hands, performing a complex pattern.

Machines for decorating

All metal engraving machines are divided into three groups.

Milling machines. Used to decorate parts of large thickness. Designed for metal processing, wood, plastic. Such engravers have large sizes, but in the work are convenient due to the lack of vibration and ease of use. Equipped with such a machine by the working field, over which the cutter rotates. Mills move with great speed and accuracy, which eliminates the human marriage.

Laser-based machines are used to decorate not only metal, but also glass, wood, stone, cardboard, plastic, leather, and many other materials. Very comfortable machines, perform high quality products. From the power of the laser, the thickness of the treated surface and the speed of the machine depends. The technology is based on the application of a special paste on the product, then the device leads a laser to the surface, under its action, the metal melts and evaporates.

A little bit like the principle of work on the dental apparatus. Works complete with special milling nozzles. Before starting, such a machine must be tested to get a high result from the first instances of use.

Machines for engraving have a different package. Removable parts allow not only drawings and inscriptions, but also to produce polishing, grinding or to make holes in the metal. Inscriptions and drawings are created as a result of rotation of a small nozzle in the form of a cone, which thumps the metal. Nozzles on cars can be several varieties:

• cutter;
• wire brush;
• grinding circle;
• tip for polishing;
• drill;
• discs;
• boers.

Engraving technology

The laser metal engraving is the greatest durability, which causes its high price. Jewelry with inscriptions or patterns engraved with a laser, quite expensive. But the most beautiful is diamond engraving. It is performed by a special milling cutter, which, removing the top layer of metal, forms four-gamped holes that can sparkle in the light. It is used in jewelry art and in the production of souvenirs. But the price of such products is high.

Types of Engraving Technician:

• Strike. It is a shallow metal thread in the form of strokes, contour lines, points and various recesses. Performed by a special tool - a shyhel.
• Obrand or three-dimensional engraving. This is a mechanical method. It is deep three-dimensional images. Volumetric drawings are obtained using machine tools or engraving machines.

During the engraving process, the drawing is applied to the metal with a cutter. Engraving technology implies both plane and three-dimensional engraving.

It is performed on flat or bulk products and is intended for applying inscriptions, contour drawings and graphic works. It is performed using a cutter. To implement the process of plane engraving, you must perform the following steps:

1. Preparation of drawing. The drawing is performed on paper, in full size, all shadows and transitions in the drawing are shaded.
2. Preparation of the surface. Clean and grind a metal surface. The ideal result is achieved with fine-grained emery paper or pumice.
3. Transferring images to the surface. The surface is covered with a small paint layer - white watercolor or liquid diluted white gouache is suitable. The drawing is transferred to dry paint with a sharp pencil and copying.
4. The finished sketch must be covered with a varnish on an alcohol basis or nitrolek for its consolidation, otherwise it will erase during work.
5. Conduct engraving manual or mechanically.

The process is best done on the matte surface - so glare from polished metal will not interfere with the work. If a glossy effect is needed, then the polishing must be carried out after engraving.

Three-dimensional engraving

A more common type of engraving than flat. The image may be embossed, or even sculptural. And you can also make a convex or in-depth image. It is widely used not only in the manufacture of art items, but also in industry. Phased performance of three-dimensional engraving:

1. Translation of drawing with watercolor paints and acute tools. I translate the image using copy paper and with wax.
2. The surface is covered with a thin layer of molten wax, and then translated on it.
3. Engraving. If the image is convex, then first make the contour with a sharp tool, and then the metal layer is removed around the image. Relief is applied to the already in-depth surface.
4. If an in-depth pattern, then after the contour is outlined, remove the metal inside the image, constantly comparing the depth with the sample made of plaster or plasticine.

The finished image is clean, grind and polished to obtain the final result. High-quality grinding will provide a special device - straight grinding. Modern production ensures the presence of special stamps that facilitate the process. But in this case, serial production is obtained, and not an individual unique work. Such engraving is suitable for the release of a series of identical works when necessary.

Implementation of engraving at home

Engraving at home can be performed both using a engraving machine and manually. Very convenient milling engraving due to simplicity machine.

Stages of performance of the milling machine

When using a mechanical engraver, you must perform steps:

1. Apply a drawing on the surface of the metal.
2. The machine cutters must be moved in one direction, repeating the image lines.
3. The image must be secured with a colorless varnish or a thin layer of wax.

You can buy a machine-engraver with a whole set of different nozzles. Their use diversified drawing by applying different lines thickness.

Stages of performing work with the help of girlfriend

If there is no possibility to purchase a machine for milling or laser engraving, then you can use the materials that are always under hand: nail polish, sharp toothpicks, salt, charging for the phone, lacquer removal, and a glass. Stages of performance:

1. Abundantly cover the surface with varnish.
2. Scratch the drawing on it with a toothpick.
3. In the glass mix 2 tablespoons of salt and some water.
4. Attach the end of the charger plus to the engraved metal, and a minus to any other metal. This other metal object is placed in a mixture in a glass. Charging turn on in the outlet.
5. After 5 minutes (it is smaller, if the depth of engraving is required smaller), turn off the device.
6. Erase the remains of varnish from the product.

This method, possessing minimal cost, will help engrave inscriptions and simple patterns on stainless steel gift spoons and other metal products on their own, at home.

The prehistory of the purchase lies in the fact that the wife of a friend is on leave to care for the child, in order not to sit without a business, decided to try himself in needlework. It all started with the flower bowls, but gradually all this began to go to a larger format, she learned to make a beautiful dress from Fatin, after that he learned to make up children's t-shirts by birthdays and make various accessories on this subject.

So, for the design of the t-shirts, nonwoven material is used - felt, from which you can cut various figures and letters, and then stick them on the required base. This process, it is necessary to say quite time-consuming, takes considerable time and besides, cut beautiful letters with certain font quite difficult. It is to accelerate and facilitate this process that this laser engraver was ordered.

The program is pretty easy to use, below shows the screenshot of the main window and I will tell a little about the main elements

Since the program was with a "slightly specific" interface, and we did not find a full-fledged leadership to her, I had to get used to it for some time and deal in the peculiarities alone. I will stop dull on some of them, perhaps it will help someone in the future.

So, first, the program window is not able to change its size. I do not know from what considerations it was done by developers, but this is so. Because of this, expand the program to the full screen for comfortable work will not work.

Well, though it is possible to scale the working space using a mouse - the scroll wheel. But it is also not quite usually. The direction in which the image will shift during scaling depends on the location of the mouse cursor at this moment relative to this image itself. This technique is often found in editors, but there, firstly, it is used using the hotkeys, and secondly, it is an addition to the standard elements of the interface - scroll strips of the window. In this case, we do not leave any alternatives - just so and nothing else.

Well, to do, even to such non-standard solutions can be used to it.

So, for example, the same pattern of butterfly looks like scaling. Here I want to immediately pay attention to the dimensional ruler, located on the left and on top of the working area.

Immediately I will say that I didn't turn to the end to the end because of the lack of time and, besides, the device is still not mine, but I will try to draw something that I managed to do, perhaps someone will help someone later. I will be expressed in a simple way, so if somewhere something is not so please - please apologize in advance.

So, it turned out that the laser operation requires a flashing that switches to work with this PWM itself. The default firmware, which is necessary for working with BenBox-Ohm and similar programs refers to the GRBL version V0.8, and the GRBL V0.9J firmware is needed to work with PWM (all these firmware in its original form or them, but in the finished form You can download the link that I gave earlier). T2Laser. With it, it turned out to manage the movement of the laser, as well as include it in various modes provided by the same program. It allows you to handle images and translate them into the G-code, but can she burn out and did not understand. Unfortunately, the owners needed to quickly return the laser into the working condition, so I had to flash back to the 08th version of the firmware and return the jumper to the place.

This experiment ended on this.

This engraver did certainly liked, because Fully justified the assured hopes and found its useful use in life. The only misunderstanding, of course, the BenBox program, a very specific thinking, judging by its developers. So to distort the principles of "intuitive" and "friendly" interface was necessary to manage.

Well, okay, it is absolutely possible to get used to it, but here one thing is still very inconvenient - it is not enough of the parameter responsible for the number of passenger passes in the drawing. If the laser was comparable in power with professional, then the questions would not arise, one pass and everything is ready, but in this case, when you need to make several passages to cut through the figure, you have to control the time and run the following passage manually.

Flame-sss.

By the way about cutting plywood.

Although engraver was not originally purchased for her cutting, but the owner liked so much that we did in the end that now he was already attended the acquisition of a more powerful module for 5000mW, so if it still happens, I promise to make one more review and Share what and how else can be cut in this way.

Thank you for your attention and all good.
