Machine with emery ribbon with your own hands. Production of a ribbon grinding machine. The process of assembling the machine to make it as high quality

Tape grinding machine on metal relates to category universal toolswhich differ in a wide area of \u200b\u200bapplication. It is suitable for working with various materialsBut the optimal ratio of speed and quality is formed precisely with the metal.

Without this equipment, the change in size, the creation of ideal forms, bright shine and an attractive look of products, which is especially relevant when working with details that have non-standard execution are markedly complicated. The main purpose is to conduct a finishing stage of processing. The devices of this species are used, as a rule, to form elements that have a production destination.

Description

Just look at the metal russian productionAnd immediately becomes clear the principle of his work. The central part of the device is concluded in the grinding tape. It is a working surface used to bring billets to the desired type. The tape can be different, its characteristics are determined by the amount of abrasive and graininess. The quality and processing intensity depends on the last parameter, and the abrasive element can be represented by diamond, silicon carbide or aluminum oxide. If necessary, this part is replaced with another.

Metal: Characteristics

The tape selection is of particular importance, since the low-quality product or not appropriate to the materials used will complicate the processing and obtaining the desired result. The maximum smoothness of the workpiece is ensured by the removal of a thin surface layer using an abrasive spraying. It is enough to choose a suitable tape - and it will be possible to form a mirror surface.

Household combined ribbon grinding machines for metals are another main part - this is a working drive. Movement of the processing tape is made by the electric motor built into the design. Among the features of the equipment, it is worth noting the preservation of the stability of work under any operating conditions and carrying out the processing process with a constant speed of the tape movement.

The tool functionality is sufficiently extensive, it can vary with the work of the built-in modules. This ensures the possibility of crossing, stripping and grinding blanks. Treatment can pass various forms, not only flat, but also non-standard. It is also worth noting the possibility of grinding round items both with external and inner side, and the processing of smooth planes.

Exist certain rules, compliance with which is necessary to ensure safe and high-quality work, the main of which are the following:

Overheating is able to determine the physical and mechanical characteristics of the workpiece, so during all steps it requires constant control of the heating of the material.
The tape should be stored in suitable conditions With stable temperature mode and moderate moisture.

Benefits

According to the metal, its own hands is made quickly and has many advantages, it is worth noting some of them:

The possibility of adding optional elements of various purposes.
The work process is characterized by a minimum level of vibrations and noise, which makes noticeably simplifies the task of the masters.
Intuitively understandable management, thanks to the newcomers, the minimum amount of time is required to develop equipment and increasing labor productivity.
No need for carrying out service. All items can be repaired or replaced by their own.
The fine processing of products from metals and alloys due to the high speed of rotation of the tape is carried out.

What you need to know

Choosing a ribbon grinding machine for metal, it is worth paying special attention to specifications. The width may be different, this parameter is indicated in the numerical code. There is an equipment that has a two-speed operation mode. Its main advantage is the possibility of processing products from of stainless steel and non-ferrous metals.

Choosing materials and tools

The metal ribbon machine is indispensable equipment for any workshop, thanks to the possibility of processing different products. But high-quality devices that are presented in stores are characterized by a fairly high cost, which is why many people prefer to make them independently. Such a tool can be made at home with the help of an electric bike, grinder and drills. Also there will be no extra helping to the turner.

There are many varieties suitable for different types Processing, they can have any dimensions and several rollers. Most of them are designed for processing in vertical planes. Despite this, more useful and convenient will be a multifunctional belt grinder for metal, capable of working in two planes. Due to this, it becomes possible to carry out almost all tasks, since the planes allow working with the workpiece under any, pre-exhibited angle.

Independent manufacture

You can do with your own hands using the minimum amount of tools, it will have a base made from sheet metal. The assembly is recommended using electric welding, which will simplify and speed up the work. It is also possible to use screws, but they reduce the strength of the finished design and require drilling large number holes. Bulgarian will become indispensable when cutting plates.

Some details better entrust the professional milling machine, for example, semicircular grooves on elements that provide a platform turn. For self-cutting, you will need a drill, boring, files and shag.

The optimal material for the manufacture of rollers is duralumin and titanium, in the absence of blanks from required material You can use standard steel. At the same time, the creation of a large roller located on the pulley and the taking thrust from the engine is possible only from steel, since the preparation of this size from titanium or duralumin is almost impossible to find.

Videos

The roller must be equipped landing places For bearing and have a hollow design needed to facilitate weight. It is worth noting that, after the ribbon grinding machine for metal is assembled, all rollers must be on the same line, non-compliance this rule will lead to frequent jumping abrasive element.

The width of the rollers may be different, it is selected depending on the size of the abrasive ribbon, which can be purchased in finished video Or glue yourself. Before entering into the manufacture of rollers, it is necessary to draw up the drawing, while the products ultimately must acquire a barrel-shaped form, which is necessary to prevent the tape scoring from the surface during operation.

On the outside Rollers should no roughness and burrs. It is not recommended to use bearings open typeSince they will quickly fail due to a large amount of dust produced during processing. Optimal option There will be high-quality details made by proven firms, as the rollers have sufficiently high revs, especially the details of a smaller size.

Tape and tensioner

With their own hands is complemented by automatic tension of the ribbon produced by a spring with suitable elasticity. It is worth noting that such equipment simplifies the operation of tools, since there is no need to create a tensioned threaded element, and the ribbon replacement process requires a minimal number of actions. For processing metal products, this is especially true, since during grinding it is necessary to constantly change the abrasive part.

It is impossible to use the tape on a paper basis, as it has insufficient strength. Bonding can be done in any convenient way, it is necessary to enjoy special elastic gluewhich today is presented in an extensive range, and enhance the seam with a square made of high-quality, fine tissue, glued on the inside. The principle of gluing can be copied with any store ribbon intended for grinding hand tools.

The ribbon grinding machine is made with their own hands without the participation of helpers and becomes more functional due to the creation of an additional table near the latter motor pulley. The main thing is not to forget about the special connection of the switch, that is, using it, the direction of rotation of the engine should be changed. It is worth noting that the pulley and tape are rotating towards the table.

Engine

It is recommended to use a 220 volt electric motor and a capacity of 1.5 kW. When using an aggregate by 380 volts, requiring connection using a star or triangle, as well as the use of capacitors, the device power will decrease by 30%. It is desirable that the engine has a console mount and sufficient number revolutions that will provide great efficiency Machine.

Features

After assembling all the elements, the metal ribbon grinder can be operated both in horizontal and vertical position. The change of position is made with a minimum number of actions, which makes noticeably simplifies the work. Equipment effectively not only when grinding metal surfaces, but also when scrolling the welds on the billets from sheet material. Special convenience is noted in the processing of smaller elements. After all, it is not for nothing that such equipment has proven itself in the field of knife production.

Despite the fact that the creation of the tool requires sufficient time costs, in any case it will cost much cheaper than a branded machine and will have an extended functionality. It is recommended to use high-quality metal piles during cutting, you can also use a plasma cutter that will noticeably speed up the manufacture of equipment.

Conclusion

The ribbon grinding machine for metal has gained its popularity due to the extensive spectrum of work. At the same time it can be equipped additional elements To ensure the necessary functions. It is worth noting that even the simplest equipment is intended to perform tasks with various complexity.

The selection of one or another option is made both by technical parameters and according to the functionality. The greatest distribution has purchased devices with an extended list of characteristics. Modern assortment of equipment for processing metal products allows you to pick up required tool with the desired functions.

The cost of the factory manufacturing machine is quite high. If the power tool does not afford, you can try to make it yourself. On such a machine, it will be possible not only to grind wooden blanks, but also to sharpen the tool. You can collect the grinding machine with your own hands, you can three species: a ribbon, disc and drum.

To assemble the grinding machine of the belt type, the electric motor will be needed, a durable bed and rollers on which the tape will rotate. Be sure to have a drawing or detailed schema With all the nodes and sizes. An example of the scheme of the machine with a wooden bed We offer to look at the photo.

On the next photo Presented finished design Machine. In this embodiment, the location of the three work shafts is designed so that the moving tape forms a vertical grinding plane. The drive used belt transmission.

In the design of the machine you can use four rinks. One of them is the leading and affected directly on the motor shaft. The photo shows an example of such a design. Installation of four rinks allows you to get two grinding planes: horizontal and vertical.

The wooden bed smoothes the vibration of the operating electric motor, however, the wood is short-lived. Optimally billet with a size of 50x18 cm Cut from steel 2 cm thick. One edge edge make perfectly even to secure the platform for the electric motor. For the next part, it will take steel with a thickness of 1 cm. The site is cut with a size of 18x16 cm, after which they are fixed to the bed with a bolted compound.

The high power of the electric motor for such a machine is not needed. Suitable engine from the old washing machine. If high performance of the grinding machine is required, then it is advisable to find an electric motor with a frequency of rotation of the shaft of 1500 rpm with a capacity of 2.5 to 3 kW. High-quality grinding can be achieved when the emery ribbon is moving at a speed of 20 m / s. To achieve such parameters, use workers drums with a diameter of 20 cm. If you make thinner rollers, you will have to reduce the rotational speed of the motor shaft using a gearbox, which is extremely uncomfortable.

The leading drum can be placed on the motor shaft. If this option is not suitable, a separate node is manufactured. The presenter shaft with bearings is fixed on the bed. With the end of the end, the pulley of the belt transmission is planted, and from the other end the leading drum is installed. Then the electric motor is also planted with a pulley and put on a wedge belt. The slave rollers rotate arbitrarily on the bearings.

Belt pulleys will have to be pulled on turning machineAnd the rollers can be made from square pieces of chipboard of 20x20 cm. The plates fold on each other until the total thickness is 24 cm. In the square of square plates, the hole is drilled, insert the heel with thread and tightly tighten the plates on both sides of the nuts. The square blank is pulled up so that the drum is a diameter of 20 cm.

During the roller, the roller provides thickening in its central part. In relation to the edges of the drum, the difference must be 3 mm. Due to the thickening, the tape will not move from the rinks. The surface of the wooden drum is tightened by rubber. Suitable old cycling chamber. Rubber will prevent the ribbon slipping on rinks.

For the manufacture of grinding ribbons will suit sandpaper on a tissue basis. You can cut a whole strip of the required length, the edges of which glue the jack. If there is no long strip of sandpaper, cut off the strip of durable fabric and stitch it into the ring. Entry paper is cut by rectangles, after which they stick to the strip of fabric. In the manufacture of grinding ribbon It is important to choose high-quality glue so that the sandpaper does not penetrate.

Making a disk grinding machine

The disk machine is considered the easiest in the manufacture. The principle of his work resembles ordinary electric eats. The grinding machine assembly is represented by instructions with step-by-step photo:

Power installation machine stands three phase electric motor. Such a choice is not accidental, since the phase change when connected allows you to organize a reverse. To the network 220 in the motor can be connected through capacitors.

The working disc is cut from plywood with a thickness of 1.5 cm. Two identical billets glued together. As a result, a 3 cm thick disk is obtained. The hole is strictly drilled, the diameter of which is equal to the thickness of the electric motor shaft.

For the assembly of the bed it is better to use edged boardand guide and desktop cut out of plywood 1.5 cm thick. Tree for machine manufacture better suitablethan metal. Wood extinguishes motor vibration.

The working disk can be grinding and even sharpened. It is important to choose the abrasive materials correctly. They should be on velcro and fit their intended purpose. If you need to grind the product from a stone or granite, a diamond circle "Turtle" is placed on the working disk.

To polish the wooden billet, the circle of sandpaper is glued to the work disk.

Similar circles on velcro are metal. On such a disk you can sharpen knives, axes and another tool.

When designing a disk grinding machine, it is important to take care of safety. From above, the rotating working disk is closed with protective arch. The working table includes a regulating heel, which is focused for the workpiece.

The tabletop of the machine should not open with varnish or paint. Over time, unevenly erased coating will create difficulties of moving the processed billet.

Making a drum machine for grinding board

For the manufacture of drum Machine Collect the face. It will take a timber from solid wood. The electric motor with pulleys is fixed from below. The drum with bearings is suitable from the served conveyor. Entry paper is cut with ribbon and wound tightly on the working rink. At the edges of the drum, the paper is fixed by clamps.

Fasten the working rink from above towards the bed. Under it will be the tabletop of the machine. The pulley is placed on the drum shaft and create a belt transmission with a motor. The countertop makes adjustable on the screws so that the boards of different thickness can be grinding. In order to avoid the vibrations of the machine, the feet of the bed is preferably fixed to the floor.

If you try and attach an effort, anyone considered the unit will not work worse than the grinding machine of the factory manufacture.

All materials in any production, in addition to the manufacture, require even additional and finish treatment. Bright examples Such treatments can be called grinding and polishing of the product. These two types of mechanical exposure to the surface of the part, bring its appearance to perfection. However, everyone knows how to perform these operations with their hands, will leave a lot of time and strength, and the uniformity of processing can ensure except that an experienced master. To facilitate this kind of work, a person came up with various adaptations and mechanisms to help. Some of them will be discussed further.

General purpose and types of machines

The machine is designed for final processing details and blanks from different materials By affecting them with a surface with an abrasive or diamond spraying. The machine, its component mechanisms and devices allow you to observe the accuracy of size and shape, and also provide the creation perfect surface Details or blanks.

With the help of the machine, you can handle flat parts, surfaces outside and inside, details of various geometric shapes, grinding or polishing the thread and teeth of gear wheels. In its characteristics, grinding machines are divided into:

Circular sloping.
Intrahelifing.
Enchanted grinding.
FlatShelipoval.
Special machines (for grinding threads, gear wheels).

Grinding process

Grinding is the process of removing the upper layer from the surface of the processed part using the use of abrasives or diamond crumbs. They are assembled in total mass on working surface and fasten the binder. They form a grinding wheel or ribbon as a result.

During the operation of the abrasive surface there is a circular motion with electric engine. When contacting the surface of the blank with an abrasive and the processing process takes place. There is a commodity opinion that grinding abrasives is friction treatment. However, it is incorrect.

Each abrasive particle has sharp edges when touched with material (metal, plastic, wood, stone) works like cutting tool And it removes the chips, how to say the cutter or drill. If you take into account the considerable speed of rotation grinding circles, as well as the occurrence of chips, as a grinding product, it is necessary to consider and the possibility of injury to this chips.

Safety measures during work

When working on the machine, the following safety regulations are required:

The need for production and in everyday life

Today, grinding machines are used constantly in production shops. Depending on the scale of production, both one machine can be installed, and all its varieties in complexity and dimensions.

However, in everyday life, there is always use in everyday life. In some - in the garage there is a vertical emery metal for processing metal. Others - in the workshop are set several different designs grinding machines on wood. Third - in possession is a universal, combined Machine. There are power tools for manual grinding: drum type, lintishlyphic, band saw, small machines or large machines. And they are all in demand.

The market presents a fairly wide range of all sorts of similar equipment from many manufacturers. And they are quite acceptable prices. But these are general-purpose machines. And if a person is engaged in his own business, or he has a hobby, then a special specialization machine needs. Here the price is already growing several times.

For this reason or based on own desires Many craftsmen make homemade. Basically for wood processing, plastic and metal, less often for cutting and grinding stone. And, in general, it is correct. After all, even simple sharpening kitchen knife It's easier and faster to make on the machine than manually using donel. Before creating your own hands homemade machine For a tree, there is a completely non-human design.

The grinding machine with their own hands for the tree is completely simple. In the people, it is also called simply - emery.

The main component of the element is the engine. Surely many in the farm there will be an old washer. Its motor for this purpose is quite suitable. If not, the new engine on the market will cost quite expensive, but on any flea market you can find used in working condition. The electric motor must be strong from 750 W to 2 kW, not high-speed from 1500 to 3000 rpm, if three-phase, then you can always adapt under 220 V. Thick plywood, self-tapping screws, PVA glue, well, and tool, of course.

Task Simple: Make hDDon which sandpaper paste. To do this, draw a circle with a diameter of 150-170 mm on the plywood, if the plywood is sufficient thickness to hide the clamping nut, just one billet. If not, we glue the two identical billets with PVA glue. The engine spindle nut must be recessed into the disk flush with its work plane.

From the same plywood 15-24 mm, you need to make several parts:

The bed to which the engine will be mounted.
Table of feeding with guides to change the angle of inclination.
Disc defense design.
The base for fastening the entire machine to the workbench.

The protection for the disk can be made in the form of arches with straight corners or truncated. She, like the table of filing, is attached to the bed. Of additional devices You can install on the feeding table of the stop-transport, which will allow you to apply a blank under a fixed, horizontal angle.

Giving tribute to aesthetics, preferably every detail before assembly to polish. But it is, if desired, but with the table of filing it must be done carefully. The smooth surface will provide a uniform and continuous movement of the part along the working surface of the disk.

The appointment of this machine opens in its very name - plane oxylphous, that is, for grinding flat surfaces of parts and blanks. It can be a disk, drum (by the type of flights) or tape. In this case, its working surface can be located vertically, horizontally or regulated.

Separate designs of machine tools are made fully adjustable. But it is individually. Homemade cars Everyone does for themselves to work more convenient. Constructions with full adjustment make harder. They are regulated by clamping drum or tape, that is, in other words, there is the possibility of fixed movement of the working surface along the vertical axis. And the girlfriend has a movement mechanism in two directions, like a carriage of the cutter holder on the lathe.

By verbal description It is difficult to imagine how it looks. And the more difficult to understand how it works. But today we have the Internet. There you can find rollers where the craftsmen share their experiences, explain in detail and show how to make such equipment. Detailed drawings and schemes with accurate sizes and directions are provided which material to use for the assembly. In general, if there are difficulties with independent design, you can always just make someone's copy.

This machine was invented for processing long details. Abrasive tape has basically fastened cloth fastened in the ring. Dimensions exist different. It is driven by the same electric motor with similar characteristics. But some craftsmen replace the drill engine. Good drill - Universal tool in many parameters. However, such a replacement is more relevant for small size Table machines, as a rule, use modelists.

How is the ribbon grinder going with her own hands? The tape is tensioning between two shafts or drum rollers. One of which is the presenter (it is attached to the engine spindle), and the second is the slave (it ensures the tension of the grinding tape). For the tape did not score from the drums, the washers-stops are attached to their ends. It turns out something like a textile coil. With minor skews, the tape wear occurs faster than the edges of the ribbon rubbing on the lock washers are destroyed. So this idea is quite viable and justifies itself.

Also between the drums from the back of the tape, the support screen is installed, which provides a dense clamp of the entire plane of the billet to the surface of the tape. To reduce the strength of friction, the screen is thoroughly polished. It is possible to make it from both light metal and solid wood.

Leading roller must be cut or made from rigid rubber. This will ensure the impossibility of slipping the tape over the surface of the roller. The whole design can be positioned differently: vertically, horizontally or at an angle. To the shared bed, as well as on all similar machines, the girlfriend is fastened, at an angle of 90 degrees, or adjustable. The distance between the ribbon and the edge of the girlfriend should not be more than 3 mm. Due to the fact that the tape break is not able to cause significant injuries, protection is made only to remove grinding products.

Homemade Grinder

Grinder is a high-speed lintishlyphic machine or a universal machine. Working surfaces - disk and tape. The engine is used as on all machines. BUT high speed achieved when using pulleys different diameter. Pulley big diameter Mounted on the engine spindle and is the leading. Small pulley - stretch.

On the universal machine The disk is attached to the spindle. You can install an additional transmitting roller, which will be skilled fasteners. It is done to quickly shift abrasive tape.

From the remaining grinding machines, Grinder is characterized by processing speed and versatility. Using replaceable ribbons for different materials, you can quickly process the surfaces of even high-alloy steel.

The working surface of wood after cutting needs special processing. Eliminate roughness and other flaws for further applying paint coating Spring will help.

The grinding machine on a tree is capable of performing concluding technological operations related to calibration and leveling surfaces. At the same time, the cost of acquiring such equipment will be minimized. Unlike factory models, they have small-sized sizes, so they are easy to install in the workshop, in the garage or in the barn. Special qualifications are not needed to work with them. Enough to know functional features Devices and follow safety. Grinding machines are used in everyday life, in construction and in furniture production.

Design - initial stage

Different models of grinding devices allow you to handle all sorts of wooden materials.

Before starting to make a homemade grinding machine on a tree, it is important to determine what kind of goals it will be needed.

The technical parameters of the instrument will depend on this:

The productivity of the device affects its power. For home use It will be enough 400 W. High performance provides machines with a capacity of up to 1 kW.
The quality of the grinding is affected by the speed of rotation of the working tool. The maximum indicator is 3 thousand revolutions per minute.
Depending on the type of surface being treated, the working area is calculated. It depends on the width of the machine drums.
The size of the machine is an important indicator where the equipment will be used: in the workshops or in a small domestic workshop.

Simple homemade grinding machine

Varieties of equipment

Wooden machines have the same principle of operation - the surface is polished with the help of abrasive material, for example, ribbons from sandpaper or circles with a rough surface.

Grinding machines differ from each other by the structure and sphere of use. Depends on the purpose of the device, which drawings need to be used in operation.

Ribbon Machine

The simplest of all models for domestic use. It allows you to adjust in different planes, clean and give fit form Products.

The basis of its mechanism is the abrasive tape stretched between the shafts, which is located in a horizontal and vertical position or at a certain angle. Under it is a working surface with a low coefficient of friction, which rests on the tool.

During the operation of the device, the speed of the mechanism can be adjusted. There are several models of ribbon grinding machines. They can be with a stable and movable desktop, and with a free ribbon.

The obligatory element of their design is the exhaust device for removing dust. For the manufacture of homemade, the electric motor will be needed, which can be removed from the old washing machine, rollers and a strong bed of metal sheet.

Working elements are made from chipboard. The drive shaft is directly connected by the electric motor, and the other freely rotates on the axis, for the mounting of which bearings are used.

Abrasive tape from the emery canvase is strictly in the middle of the shaft. It should smoothly touch the surface and not slip.

Such consumables may be needed to build designs:

boards and bars of wood;
metal pipes;
bearings;
electric motor;
pulley;
rubber belt;
fasteners;
abrasive material;
work tool for mounting;
welding machine if the casing of the bed is made of metal.

Drum device

It is necessary for horizontal alignment and calibration of surfaces. With it, you can handle the rails and mDF materials and chipboard. The design of the device consists of two rollers with a spiral stretched with an abrasive ribbon.

Under them is a smooth countertop on which the workpiece is located. The distance between the shafts and the working surface is adjustable.

Work on the manufacture of the drum machine is performed in stages. First, the case is made from sheet steel or plexiglas, then the engine is mounted. The drum creates an abrasive tape or a cone with cutting edges.

At the top of the circuit, the desktop is installed. It should be regulated in relation to the vertical cylinder. As a control, the on and off buttons are used.

Disk device

Another simple homemade grinding machine is disk. It is necessary to calculate large wooden products. As a working tool, an abrasive circle is used, which is attached to the axis of the electric motor.

In the center of the disk on the hinged mount, a special stand is installed, fixing the part at a certain angle. To improve equipment, experts advise the use of wooden disks with different species Emery paper.

Combined option

Combines round-fluff and plane grinding equipment.

Make the device in this way. A shaft with a diameter with a diameter of up to 230 mm is attached to an enlarged end of the belt-grinding machine.

It uses a belt transmission. The design is complemented by a supporting table. Combined technology will save space and provide convenience in work.

Proper operation of equipment - a deposit of successful work

The process of mounting the grinding machine on a tree is obliged to meet all the requirements of safety regulations. This should be remembered by each wizard to prevent cases of injury in the workplace:

The manufactured machine is made from qualitative materials and has reliable design. During surface treatment, it is impossible to ride the hands of the working tool and moving parts of the mechanism.
Work on homemade grinding equipment is needed in protective glasses.
For wood work, it is impossible to use discs intended for metal processing, since they have another surface structure.
Before starting work, it is important to check the health of the design details.
The use of protective casing for grinding circles increases the safety of work.

All materials in any manufacturing, in addition to the manufacture, require even additional and finishing. Bright examples of such treatments can be called grinding and polishing of the product. These two types of mechanical exposure to the surface of the part, bring its appearance to perfection. However, everyone knows how to perform these operations with their hands, takes a lot of time and strength, and the uniformity of processing can ensure except a very experienced master. To facilitate this kind of work, a person came up with various adaptations and mechanisms to help. Some of them will be discussed further.

General purpose and types of machines

The machine is designed for the final processing of parts and billets from different materials by affecting them with an abrasive or diamond spraying. The machine, its component mechanisms and fixtures allowt absence accuracy of size and shape, and also provide the creation of an ideal surface of the part or blanks.

With the help of the machine, you can handle flat parts, surfaces outside and inside, details of various geometric shapes, grinding or polishing the thread and teeth of gear wheels. According to mine characteristics Grinding machines are divided into:

If we take into account the considerable speed of rotation of grinding wheels, as well as the occurrence of chips, as the grinding product, it is necessary to take into account the possibility of injury to this chips.

Safety measures during work

When working on the machine required Comply with the following safety regulations:

The need for production and in everyday life

Today, grinding machines are used constantly in production shops. Depending on the scale of production, both one machine can be installed, and all its varieties in complexity and dimensions.

However, in everyday life of this equipment There is always an application. In some - in the garage there is a vertical emery metal for processing metal. Others - in the workshop are installed several different grinding machines on the tree. Thirdly - in possession is a universal, combined machine. There are power tools for manual grinding: drum type, lintishlyphic, band saw, small machines or large machines. And they are all in demand.

The market presents a fairly wide range of all sorts of similar equipment from many manufacturers. And they are quite acceptable prices. But these are general-purpose machines. And if a person is engaged in own businessOr he has a hobby, then you need a special specialization machine. Here the price is already growing several times.

For this reason, or on the basis of our own desires, many craftsmen make homemade. Basically for wood processing, plastic and metal, less often for cutting and grinding stone. And, in general, it is right. After all, even a simple sharpening of kitchen knives is easier and faster to do on the machine than manually using donel. The benefit of creating their own hands a homemade machine for a tree has a completely non-suty design.

Grinding machine with your own hands For a tree, collect quite easily. In the people, it is also called simply - emery.

The main component of the element is the engine. Surely many in the farm there is an old washing machine. Its motor for this purpose is quite suitable. If not, the new engine on the market will cost quite expensive, but on any flea market you can find used in working condition. The electric motor must be strong from 750 W to 2 kW, not high-speed from 1500 to 3000 rpm, if three-phase, then you can always adapt under 220 V. Thick plywood, self-tapping screws, PVA glue, well, and tool, of course.

The task is simple: make a hard disk on which sandpaper paste. To do this, draw a circle with a diameter of 150-170 mm on the plywood, if the plywood is sufficient thickness to hide the clamping nut, just one billet. If not, we glue the two identical billets with PVA glue. The engine spindle nut must be recessed into the disk flush with its work plane.

From the same plywood 15-24 mm, you need to make several parts:

The bed to which the engine will be mounted.
Table of feeding with guides to change the angle of inclination.
Disc defense design.
The base for fastening the entire machine to the workbench.

The protection for the disk can be made in the form of arches with straight corners or truncated. She, like the table of filing, is attached to the bed. From additional devices can be installed on the stop of the flexibility of the stop-transport, which will allow to feed the workpiece under a fixed, horizontal angle.

Giving tribute to aesthetics, preferably every detail before assembly to polish. But it is, if desired, but with the table of filing it must be done carefully. Smooth surface will provide Uniform and continuous movement of the part along the working surface of the disk.

The purpose of this machine opens in its very name. - plane oxylipheal, that is, for grinding flat surfaces of parts and blanks. It can be a disk, drum (by the type of flights) or tape. In this case, its working surface can be located vertically, horizontally or regulated.

Separate designs of machine tools are made fully adjustable. But it is individually. Homemade cars each makes it to work more convenient. Constructions with full adjustment make harder. They are regulated by clamping drum or tape, that is, in other words, there is the possibility of fixed movement of the working surface along the vertical axis.
