How to make a cutter for sandpaper. Tips for choosing a paper cutter paper cutter for paper

Paper cutter - Device for quick and smooth cutting paper. Very useful when making scrap-page and postcards. The cutter allows you to smoothly cut the sheet of paper, how no scissors can be raised.

According to the method of impact on the knife, the cutter is divided into mechanical (manual) and electric. In turn, hand cutters are roller, saber and guillotine types.

Roller cutter (It is a disk cutter or trimmer) is a rectangular base (desktop), along which the cutting mechanism is moving along the guide. It, in turn, consists of a sharpened metal disk concluded in a protective casing. When cutting, the paper is between the roller cutter knife and the counter (solid metal plate, fixed on the end of the platform from the other side where the cutter is moving). Such a cutter is ideal for working with a small amount of paper - up to 10 sheets, it happens different sizes, the most common - 22.5 x 12.5 cm; 31 x 31 cm; 20 x 46 cm. It takes a little space and has a valuable quality - the ability to cut off the edge of a width of less than a millimeter, which allows you to work with maximum accuracy. In roller cutters, knives are not subjected to secondary sharpening, although they are called self-folding. Just after a certain time they must be changed.

Sabel cutter called due to a knife that looks like a saber. The saber cutter is most powerful and used to work with a large amount of paper, but the accuracy of them remains in the range of 0.1 mm. Sabelny cutters have a somewhat different work principle. The sharp cutter knife is fixed from one edge (in order to avoid injury, it is closed with a protective casing), from another handle. Omitting it, cut the paper. The knife in the saber cutter can be sharpened, although this procedure is not as simple as it seems at first glance. In addition, use a saber cutter much more difficult than roller. To get the perfect result, you will have to try.

Guillotine cutter Used to process large circulation and perfectly suitable for large typography. Such a cutter is manual, semi-automatic and automatic. Its working mechanism (acutely sharpened heavy knife cutter is located on a massive table and is driven by a lever or an electric drive. The blade moves not only from top to bottom, but also on the line of the cut and can "process" the impressive packs of sheets up to 8 cm. At the same time, accuracy reaches a fraction of a millimeter. When the cutter knife is stupid, it is removed and fed, and after several sharpeners change.

Maketonian knife Used for cutting paper, sharpening pencils, as well as needed to cut small parts and complex figures. It is a subtle replaceable blade similar to a feather with a protective cap. When working with such a knife, you must have a damp rug (cardboard, organic or fane) so as not to damage the table on which you work.

Roller Macate Knife Allows you to quickly and without much effort to cut the paper, as well as make a variety of curly cuts with special nozzles.

Circular knife It is used to cut circles with a diameter of 10 mm to 150 mm. Ideal for making postcards and round parts for scrap page. The knife is an axis with a needle and a movable leg on which the blade is installed, the circle is cut into the means of rotation. Also on the mobile leg, a scale is applied, designed to select the diameter of the cut circle. Working with a circular knife is necessary on a dump mat. Before cutting, make sure that all the circular screws are spinled.

Easily cuts out any shape on a special stencil, it will not be replaced when creating decorative elements For pages and postcards. Some figured cutter models can be used without a stencil. When working with such a cutter, it is necessary to have a dump pad, so as not to damage the table on which you work and be sure to check the serviceability of the blade, if necessary, adjust in accordance with the density of the selected material.

I hope the review will be useful. We wish you all good mood!

Cutters are a specialized printing technique that is applied at large production. However, there are small models that can be used in the office and any other administrative institution.

To buy paper cutter costs any company, which with his help will be able to beautifully execute its documentation, giving it finished and presentable view. For such use, you can buy a small paper cutter, the price of which is quite affordable.

What are the cutters

To do right choiceYou should familiarize yourself with all kinds of cutters.

By type of its design and method of cutting, such a technique is divided into three types:

• disk or roller cutter . Provides high cut accuracy and is used to cut a small amount of paper;
• guillotine . It is used when cutting large amounts of paper, provides high cutting accuracy, allows you to cut large stacks of papers;
• sabel paper cutter . Gives relatively high cut accurate and provides a large amount of work, is used where high accuracy Not as needed as a large amount of work done.

In addition, by the type of drive, they are divided into a mechanical and electric cutter.

The first type works with the help of pressing on the handle, and the second has electric drive and allows cutting paper without the cost of physical strength.

It should be remembered about precautions when working with such a technique.

Which tells about the manufacture homemade cutter - Devices for cutting paper that can be healthy to help PNP lovers. Such cutters are sold in stationery stores, but if desired, it can be made independently.

After printing photos, pictures or games "Print and Play", it is necessary to cut the sheets of paper into parts, preferably quickly and smoothly. TO that is something cuts scissors, someone buys corporate cutters for a round sum, and someone simply cuts on the glass with the help of a stationery knife and a metal line.Each method has its pros and cons.

Since the round sum of money was not a hunt for me, but I'm tired of being cut with scissors. So I decided to make a budget option Cutter. Plowing on the Internet and thinking, I made a device that helps me when cutting paper.

As can be seen from the photos, the iron rules serve as a knife guide, and in order for the sheet not slipping with a cutting, we press it with a wooden line to iron. A wooden ruler can be replaced with a transparent plastic ruler, it will be much more convenient.

For the manufacture we will need:

• two pieces of fiberboard with dimensions of 80x530 mm;
• two metal rules with a dimension of 50 mm;
• five wooden lines with a dimension of 50 mm;
• eight screws M3x16;
• sixteen nuts m3;
• two screws M5X20;
• two nuts lamb M5;
• drill with a diameter of 5.5 mm;
• drill with a diameter of 3.5 mm.
• self-adhesive paper;
• drill or any alternative to her;
• stationery knife.

The cost of all the above will cost you about 200 rubles, without taking into account the costs of drill and fiberboard. I have already been pieces of fiberboard and drill, and self-adhesive paper was purchased earlier for 50 liters / 155 rubles.

What to buy?

I purchased the ruler in stationeryIt is advisable to first call the stores, since the rules you need sold in a pole to the store, in which I called. In the same place I acquired a stationery knife for cutting paper. Screws, nuts and drills I bought in a shopping store. Self-adhesive paper is bought there where both the paper for the printer or in the stationery.

Manufacture

Production itself is not difficult, but requires accuracy and sequence of actions.

The first thing is not necessary to do - drill holes in metal rules. Before drilling, approximately placing where we will drill, and proceed to business. In each metal ruler, you must drill four holes with a diameter of 3.5 mm. And in one metal line, you still need to drill two holes with a diameter of 5.5 mm. After that, it is necessary to check how the screws go into the holes, if necessary, expand them.

Next, using metal rules as a conductor, drill holes in the wooden rules, so that the wooden line would not perform in one edge of the metal line, a couple of millimeters. This is necessary so that the wooden ruler does not interfere with cutting, and the knife slid current between metal rules.

The next step of cutting out two plates with dimensions of 80x530 mm, and drills in one of them holes using metal rules as a conductor. Before drilling, it is necessary to set the gap between the rules in the size of the knife blade, with a margin to ensure the free movement of the knife. I have a gap of about 1 mm. In the second plate, I made holes on the place to provide access to screwdriver screws, after assembly. One dvp plate serves as a cutter body on which all the details are attached. The second plate is used to protect the table from scratching the heads of the screws. To give an aesthetic species, I plated the plates of self-adhesive paper.

We make a clamping line. The fifth wooden line must be trimmed with a knife in size 475 mm. Next, we drill two holes with a diameter of 5.5 mm, through a metal line. The clamping line is ready.

All items are ready to start assembling. With the help of lamps of self-adhesive paper, we glue and glue the DVP plates among themselves and install the screws into the holes.

Now we install a wooden "line - clamp", and screw the nuts on the screws, set the gap between the iron rules of about 1 mm. Tighten the nuts and screw the lock nuts on the screws, which will not allow to develop all the fixture. Before you need, pull up nuts during operation.

This homemade can be useful for anyone who works with paper or cardboard. It does not require much cash costs. But with accurate work will provide "clean" cuts of any paper size.

Before we proceed to discuss the topic, I note that today we will be exclusively about the rectilinear cutting of one sheet of paper. And now to the case.

Each of us at least once in life came across the need to cut paper (cardboard). What instruments do we use for this? Of course, scissors. If you need a more or less smooth cut, then the knife and ruler goes into the course. For the absolute cleanliness of the work it is better to use the corporate cutter. Let's deal with what the advantages and disadvantages of each of them.

Draw scissors

it the simplest way Cutting paper. It is convenient for small amounts of work and relatively small incision lines. Make the same high-quality and longer cuts them is extremely difficult.

Conclusion: Despite the low cost of the instrument and the simplicity of its use, the scissors can only be used to produce small lines of the cut.

Using a knife and ruler

Definitely, this method of cutting paper is more suitable for short-length cuts than scissors. You only need to possess certain skills and skills.

To do this, you can use any well sharpened knife, which will not be fastened and tear the paper. But it is better, of course, use the stationery knife, or a knife for construction work With nominating blades. It should be without a backup so that the tool cannot go away from the guide line.

As for the line. Choose, undoubtedly, you need steel. When working with wooden or plastic rules, there is a risk that the knife will "break" in them, and this will not be very well reflected on the final quality of cutting.

So, we can again talk about the low cost and ease of use of tools. However, when working with them, difficulties arise with the fixation of the line of long length, and at the same time increases the risk of being injured.

Factory cutter

Its use in all cases is more convenient and more efficient. Moreover, there are a huge number of most different species and types of such cutters: roller, saber, guillotine, etc., intended for cutting paper from A4 format to A1, as well as excellent and quality.

And, as a rule, people who are seriously interested in or professionally engage in work with paper and cardboard, try to acquire exactly such devices. However, there is a big minus here - the price of the instrument. If small cutters designed for small size and density of paper can afford many hand meaders, then more serious tools for cutting large paper sizes, for example, 70x100 cm, not everyone is available. Moreover, it is possible to recoup this acquisition, only by carving paper, as they say, in "production" scale.

Homemade cutter

Design

I myself do the manufacture of photo albums. Most often I use binding and design cardboard, designer paper and cottry with dimensions of 70x100 cm.

Choosing the design of the homemade cutter, before I decided with the requirements that, in my opinion, he had to correspond. It:

• cutting paper of different density of 70x100 cm in size;
• simple design and inexpensive components;
• acceptable quality cut.

On the Internet found pretty interesting option Cutter of two metal lines. The author of the idea is Evgeny Kuznetsov. However, the testing of this cutter showed that it is not quite suitable for cutting tight paper or tracing. I had to continue the search. The adaptation of another author, unfortunately, I do not remember his name, made me to make a more complex design.

The foundation

Found old board for drawing that was ventilated on fresh air last few years. He led her in order, scolding the strengthened edges and made it the basis for the future cutter.

Knife guide

The steel 100-centimeter ruler, though, shorten by 20 cm, came just for the guide line for the knife. To give it hardness, a duralumin rule for construction work was also bought. He also had to shorten the size of me.

Now it was necessary to securely secure the ruler on the duralumin rule. It was coming in handy once dousant rivets made to me, produced in the Union.

For better fixation, the bolt line made guides. At the same time, the holes for them drilled slightly smaller diameter than the bolts themselves. It helped tightly screw them into the board. Additionally, recorded bolts with nuts with special sleeves that impede spontaneous unscrewing.

From above, the line pulled with lamb nuts, which are well twisted with their hands. Under the ruler on the bolts, the springs was put on. If the lambs are unscrewed, the ruler on the springs is raised, and your hands will be released to work with paper.

I note that with the selected length of the cut line, even the rule is a thickness of 2 cm. After the clamp of the screws, it can bentified, and that the sheet of paper does not slip, the line in its central part is better to hold the hand.

By the way, it is more convenient to position the sheet of paper perpendicular to the line, I additionally secured an aluminum corner. It also placed an aluminum square with restraints for a sheet of paper also placed on its part. If you fix this focus using a clamp in the corner, then positioning the sheet of paper before fixing the line can be much faster.

Substrate

As a substrate for cutting paper, I chose a glass from furniture wall. Although it is better, of course, order glass of the desired size with treated edges in the workshop.

On the board, the cutter on the part of the working part of the ruler glued the sheets of the Fiberboard to align the height difference with a glass substrate.

In the case when I need to cut a thick binding cardboard, I use corrugated cardboard sheets as a substrate. The length of the guide bolts completely allows you to do it.

The only drawback of this cutter, which I can not say, is a small backlash rule on bolts-guides. It must be taken into account, spinning the shell screws to fix the paper sheet. The backlash appeared due to the inconsistency of the diameter of the bolts and the diameter of the planting holes under the bolts in the rule. But it is rather a lack of construction, and not the technology of its manufacture.

That's it. You can use such a device as an independent cutter or in combination with a factory cutter of a small format. But this is if you need a more accurate fit of the size of sheets.

The presented guillotine made by their own hands works on the principle of lever scissors, calculated for cutting sheet metal With a thickness of no more than 3 mm.

It is made of primary means, in particular from the old file and crosses of metal structures.

The manufacture of guillotine consists of several stages. First, it is necessary to carry out drawing work with the purpose of accurate definition dimensions of the product. Applied scale 1: 1.

It is also recommended to draw kinematic schemeWith which it will be possible to determine the dynamic parameters of movable parts without taking into account the current forces.


Paper drawings parts are printed on the printer, and then cut. From the cut parts is collected by the machine layout. This is done in order to make sure that the calculations produced and the exact correspondence of the dimensions are made, each individual component in the context of the functioning of the entire mechanism as a whole.

It is very important to determine the level of the cut level. It will be located at the intersection of a moving blade with a base that is conventionally designated by a pencil line.


The next step is the selection of scrap metal suitable sizes, followed by template contours of future components on them. It is at this moment that paper trimming from the cartoon turns into important stencils.


In this case, the role of the workpiece was cutting a corner and a listed piece of iron. And as a result of intense work, the Bulgarian or gas cutter obtained the main details of metal scissors. These are two ear, handle, body holder and body itself.

The base of the guillotine is attached to the base of two edge corners. Their thickness is 50 mm. Pay attention to the accounted space for visits in the mode: "Leaf Top", "Leaf Down". Also provided free space for a file. At the same time, it is necessary to proceed from the parameters of its thickness plus the required clearance.

Then with the help of mounting bolts, the process of consistent assembly occurs. The handle by means of two ears is attached to the main design of scissors. After that, one end of the body holder is bonded to it. The second is suitable with the handle.


In the end, it should turn out, this is an instance. Subject to the prevention of errors in previous stages, the moment of complete cuts should occur when the horizontal position is reached. The minimum movement of the handle against the background of the maximum move on the radius should also be achieved.


The billet for two blades served as an ordinary old one, and therefore the wastehedral, file. To begin with, it should be cut into two parts. In each of them, three holes for fastening are drilled. After that, the blade profile is generated and the immediate edge of the edges.


Images are shown on the fastening of two cutting knives. The movement of the top knife should not prevent the remaining parts of the machine. It is important to bring a profile in such a way that over the entire width of the cut, the interaction of the knives occurred at an angle of 6-8 degrees.


Homemade lever shears ready for work with clips or specifically for this drilled holes reliably fixed on working surface Workbench.

Subject to the main technological rules during the manufacture of the machine, it will definitely show very high efficiency. And it will easily cut both paper leaves and 3 m milly-grazers.
