Outside diameter of discs

One of the important indicators of the cutting wheel is its outer diameter, which is calculated in millimeters and is unified. For household purposes, as a rule, a disc for a grinder for wood 115-230 mm is used.

The tool shaft diameter (fitting size) on almost all discs is now the same. 22.2 millimeters, and special intermediate rings are used for installation on outdated grinders.

The most versatile is considered to be a disc for a grinder for wood 125 mm, 150 mm and 230 mm.

The 125 mm circle is convenient to use when it is necessary to cut metal reinforcement and a rod.

A disc for a grinder for wood 150 mm can not only grind and cut metal, but is able to saw a bar or dissolve a board.

If the diameter is more than 230 mm, then such circles are for industrial purposes.

Disc for a grinder for wood 230 mm has a wider scope, as it can be used when processing products from metal alloys of various grades.

Grinder abrasive discs

As mentioned earlier, grinder abrasive wheels are divided into cut-off (up to 3 mm thick) and grinding (thicker). Despite the fact that the classification is very conditional, there is another significant difference between the discs. the reinforcement of cutting wheels is usually carried out in 2 layers, and grinding wheels at least three.

Abrasive disc shape

Abrasive wheels differ in their shape. Distinguish:

Standard flat discs.
Curved discs (in the form of a plate). They can be used when performing work in hard-to-reach places. With this wheel shape, the fixing nut is hidden, therefore it is more convenient to perform grinding work.

When purchasing a disc for a grinder for wood, pay attention to the marking (for example, A 40 L), which allows you to find out the following information about the product:

The first letter (or two) indicates the type of abrasive used. For example: A. corundum, AS. electrocorundum, C. silicon carbide, which is used when working on granite and stone.
The numbers allow you to find out the grain size of the abrasive. over, the larger it is, the faster the work will progress. However, this will impair the cleanliness of the cut or grinding. A disc with a coarse grain is used, as a rule, for processing soft (non-ferrous) metal, and with a fine grain, it is used for steel.
The last letter in the marking gives an indication of the hardness of the bond of the base of the circle (those letters that are located at the beginning of the alphabet mean that the bond is softer). It is recommended when buying to be guided by this rule. when working with soft material, use a disc with a soft bond and vice versa.

Almost all manufacturers of abrasive wheels use color coding of products. Green is for stone, blue for metal. The inner landing ring is also worth mentioning. For wheels that are intended for cutting, it is made of hard metal, and for polishing or grinding, cutting discs with a softer washer are used.

Rubber cutting disc

Modern angle grinders, better known as “grinder”, are used for various technological processes during construction and repair work. When choosing a disc for a grinder for wood and rubber, it is necessary to take into account the characteristics of not only the tool itself, but also the objects to be processed.

Safety regulations

When working with a grinder, no matter what type of installed disc, it is necessary to strictly observe safety requirements.

The tool must be equipped with a stop handle and a protective cover.
All work must be performed in overalls and using personal protective equipment. It is also necessary to be very careful about the choice of glasses or a mask, because eye damage (according to statistics, this is the most common injury) can be obtained even from a small shavings or a fragment of the circle itself.

However, despite this, it is still recommended to give your preference to trusted manufacturers, since this tool is with increased danger. Therefore, it is not worth saving on such a consumable as a cutting disc.

The modern industry produces many different types of rubbers used in the most unexpected industries. Quite simply and quickly, you can find the necessary rubber gaskets or the necessary rubber blanks at the nearest bazaar. However, if you still needed to make a rubber product with your own hands, then a couple of simple tips on how to cut the rubber simply and neatly will come in handy.

Circle selection

When choosing discs for grinding wood with a grinder, pay attention to the following points:

The size of the circles should not exceed the maximum permissible diameter for which the grinder is designed. A tool designed for discs with a diameter of 125 mm will not be able to work with a 230 mm cut-off wheel for a variety of reasons. Firstly, the speed of movement of the grinder’s edge is significantly exceeded (with a significant increase in it, the disc may simply fly apart). Secondly, to work with such a disc, more power is needed than that for which a small tool is designed. Thirdly, to install such consumables, you need to remove the protective cover, which makes the work more dangerous.
When working with different types of materials, you should choose a disc that is designed specifically for them.
Pay attention to the maximum allowed lap speed (or line speed). These indicators are indicated on the surface of the circle. According to these values, the operating mode of the grinder should also be selected.

Diamond cutting discs for grinders

Depending on the purpose, diamond discs can be divided into several types:

Concrete. Circles of this type can easily cope with monolithic, including concrete and reinforced structures.
Granite. Such discs are used when performing work with especially hard rocks.
Asphalt. Cut-off wheels are best used when processing concrete and, accordingly, asphalt.
Construction Materials. Discs of this type can be used for cutting ceramics, bricks.

Some manufacturers’ diamond cutting discs are also color coded:

Green is granite.
Blue. concrete, marble.
Yellow. gypsum, tiles.
Gray. ceramic.

Segmented diamond cutting discs are used for cutting materials using the dry method. When using solid discs, wet cutting (water cooling) is used. This is primarily due to the very high heating of the solid surface of the cutting wheel.

There are models with partial segmentation. These are the so-called turbo disks, in which the slots are located in the body of the circle (they do not go out to the outer edge). These products can be used at a higher speed than fully segmented products.

So, having chosen the most suitable cutting disc for a grinder for wood in all respects, you can efficiently and safely perform any work.

How to cut rubber with a knife:

Rubber is quite varied in its properties, ranging from a very elastic and rather pliable material and ending with elastic durable rubber plates. The use of rubber can be found in a variety of ways, for example, cutting out a suitable sized water pad, a heel for boots, or a non-slip support under a glass surface. Many people cut all kinds of animals, swings, or make interior items from car tires. You can make flower beds from car tires, but for this you need to know how and with what to cut a car tire.

The secret is very simple, in order to neatly and simply cut a piece of rubber, you need a sharp knife, of course . and ordinary water.

A piece of elastic rubber, a sharp knife and water.

First, you need to outline the cut line (it was enough for me to just align the knife blade).

We start cutting rubber with a knife.

Cutting thick rubber with a knife becomes rather difficult as the blade deepens into the thickness. The rubber begins to become viscous, and if you overdo it, the rubber can even melt. Whatever happens, and the knife went through the rubber like clockwork, it must be moistened with water (and not oil, in no case moistened with oil).

We wet the rubber with water and cut it with a knife.

When wet, the rubber becomes slippery, and the knife blade will not get stuck or melt the rubber, thereby you get a smooth and high-quality cut without much effort.

How to cut a rubber circle

You can cut an ideal round rubber gasket of any size or belt for a tape drive mechanism of a tape recorder from a sheet of rubber using this simple tool. In addition, it can be used to cut large diameter holes in plywood, plastic, plexiglass, cardboard and other similar materials.

Making it yourself is not difficult at all. From a sheet of plywood with a thickness of 10 mm, cut three squares measuring 300×300 mm. In the center of one of them, drill a hole? 8 mm, and in the other two.? 25 mm. After gluing the blanks, as shown in the drawing, we get the base of the fixture. In its central hole, fasten the M8 bolt with a nut.

Turn the central post out of a brass rod ø 12 mm and 80 mm long. Cut an external M12 thread at one end, and an internal M8 thread in the end hole on the other side.

The swivel sleeve has an axial bore of 12 mm and a threaded M10 perpendicular to it.

The carrier is a 10 mm brass rod. At one end of it, an M10 thread is cut with a length of 10 mm, and a radial hole M3 at the other end is made after subassembly of the carrier with a rotary sleeve: it should be parallel to its hole? 12 mm.

The slider in the form of a corner is cut from a duralumin bar. In its vertical wall, two holes with a diameter of 10 mm are made. one for the carrier, the second, perpendicular to it and shifted downward by 5 mm. for the retainer. a threaded pin with a semicircular groove. A groove with a section of 14X3 mm is sawn in the horizontal wall. for a knife. The material for its manufacture is a piece of a hacksaw blade. In the vertical groove of the slider, the knife is fixed with an M6 screw.

The pressure disk is cut on a lathe from a metal plate 2 mm thick or thicker plastic sheet. Its central hole should have? 8 mm, and the outer diameter should be slightly less than the cut.

The center M12 bushing lock nut has an external Ø 25 mm and a height of 15 mm. Saw through a half-diameter transverse groove in it and make a longitudinal hole in this part. Then, in the lower half of it, cut the M4 thread, and in the upper half, drill it to? 5 mm. Now tighten the halves of the nut with a screw, this way you can lock it in any position on the B-pillar.

The assembly procedure for the fixture is as follows. Screw the carrier with the threaded shank into the pivot sleeve until it stops. Insert the locking pin into the slider so that its cylindrical groove coincides with the longitudinal hole. Putting the slider on the carrier, insert a knife into its groove and tighten it with a screw. Attach the revolving handle to the end of the carrier.

A workpiece is put on the bolt rod protruding from the base. The pressure plate is installed on it, and then the center post. You can tighten the thread with a screwdriver. a radial hole of 5 mm is intended for this. A spring is put on the rack, behind it is the carrier assembly and, finally, the lock nut.

By adjusting the position of the slider on the carrier and the bushing on the rack (in height), you can get to work.

The dimensions of the main parts allow you to cut holes with a diameter of up to 240 mm on this device, however, if you need a large size, it is enough to replace only three elements: the carrier, the base and the pressure plate. And to quickly adjust the device to a given size, you can apply nonius risks to the carrier.

How to make a round hole in rubber:

Sometimes there is a need to cut rubber circles, for example, for non-slip legs under a stool, heels, or for spacers between two glasses. In order to cut smooth rubber mugs, you need to choose a metal pipe of a suitable diameter, you also need a piston suitable for the diameter of the tube.

You need to sharpen the edge of the iron tube with a sharpener or file.

Honed iron tube

After you sharpen the tube, you need to insert it into the drill chuck, moisten the rubber with water and just start drilling the holes, having previously laid a piece of wood.

We drill round rubber gaskets

With the help of such a simple device and water, you can drill as many smooth, neat rubber rounds as you like (I use them to make non-slip feet for devices). The sharpened tube acts on the principle of a drill, but as the circles are drilled, it is filled with them, and in order to pull them out, a special piston is needed. Then you simply push the rubber rounds out of the sharpened tube.

We squeeze the rubber bands out of the tube with a piston

The main thing is not to forget to wet the rubber with water when drilling or cutting. It should be noted that it is much easier and more convenient to cut a circle using a sharpened tube than in the classical way. using a drill. However, if you need to drill the rubber with a drill, it is also quite easy to do it by sharpening it first, and periodically dipping the drill into water.

You need to drill rubber at low speeds and periodically wet the cutting edge. However, if you need to drill a large block of rubber at high RPM, you may want to submerge it completely in the water.

In the most extreme case, holes in thin rubber, as in plastic, can be melted by heating a drill shank or an iron tube with a lighter.

Rubber melted holes

The main thing is to be careful when working with hot metal. Also remember that rubber can emit toxic substances when overheated, therefore, melt holes under the hood or in a well-ventilated area. Observe all safety precautions even when drilling rubber.

It is quite simple to do this, I remember this from the time I worked as an electric-gas welder at the plant. I usually used empty sleeves, since sleeves are a very good tool. Sometimes the sleeves did not have the required diameter and had to look for an aluminum or stainless steel pipe of the required diameter. The metal of the sleeve is sharp, it is not necessary to sharpen it. But the end of the pipe will have to be sharpened on emery or by hand, so that the end is sharp and pierces the rubber.

Rubber is a tough material and can sometimes be difficult to punch or cut holes from. Of course, if you have the ability to use a laser cutter. then everything is simple, for example, which holes can be accurately cut using a laser cutter.

But since many of these cutters do not have such cutters at home, I give advice as I do. First of all, it is necessary to understand how the properties of rubbers change under different conditions. So, when cooled, the rubber becomes brittle or, as experts say, they enter the glass transition phase. But when heated, the rubber becomes softer and of course it is easier to cut or punch an even hole in them. But you can use one more property of rubbers, namely the swelling process in various solvents. So, for example, if you soak rubber in xylene, then it is cut and punched much easier and the holes are smoother. so it is necessary to soak the rubber in a plastic bag for 30 minutes in xylene and then you can cut and punch holes quite easily.

How to cut thin rubber

Thin rubber can be carefully cut with a knife or large scissors. The most important rule to remember is to stretch the rubber well.

If the rubber blank is not taut when cutting, the cutting tool blade will be strongly clamped. If you tighten the rubber when cutting, the blade will not clamp, so cutting the rubber will become very simple and easy. In addition, the cut itself will look much neater.

How to cut rubber

Cut the rubber with a thin blade. It all depends on how thick the available rubber blank is. It can be a thin and sharp knife or a thin file. A thick blade will get stuck in the rubber blank more and it will be much more difficult to cope with the task.

In addition to the main tool with which the rubber is cut, you will also need lubrication. The fact is that the saw or knife gets stuck in the rubber blank, so cutting is very difficult. If the rubber is lubricated with soap or some other lubricant (you can use anything), then things will go much better, because the cutting tool will glide well and will stop getting stuck.

The boot knife shows itself well. In this case, it is better to cut the rubber not like a loaf, but literally rip it open with a knife. So the work will be done much faster, easier and more accurate.

How to cut thick rubber

If you need to cut, for example, a tire or some other thick rubber, you should also try to tighten it. In any case, after the start of cutting, it makes sense to use a spacer in the cut so that the blade does not get jammed.

Of course, even in this case, it will be extremely difficult to cut the thick rubber. Therefore, a lubricant comes in handy here. You can use machine oil, soap, or something else. It doesn’t matter at all, the main thing is that the blade glides well.

Of course, here it is advisable to use a good metal saw with fine teeth, since a knife, even a boot knife, can do little when the rubber blank is really thick and massive.

As a result, we can say that rubber is actually cut very easily and well. The problem arises due to the increased coefficient of friction of this material, which is removed, firstly, with a thin blade, and secondly, with any type of lubricant.

That’s all you need to know in order to accurately and easily cut rubber of any thickness. This is not easy, unless you use the simplest tips that are presented in this article.

How to cut a car tire?

When you need to cut a car tire (tire) with your own hands, it is better to know some tricks that will not only help make this process more enjoyable and less laborious, but also help protect yourself from injury and make the cut better.

First you need to know the structure of a car tire (and any other equipment).

Since the surface that the tire touches the ground is more difficult to cut, as there is a metal cord.

To do this, you can use it, like a hand hacksaw, lubricating it with oil or soapy water or a grinder with a disc for metal.

I must warn you, if you have never used a grinder before, it is better to use a hand hacksaw, since it is not difficult to catch the clamping of the disc when cutting the tire. For this procedure, you need to hold the tool firmly and be able to cut correctly.

With the side part of the tire, the situation is much simpler, there is no need for a special tool, but care must be taken.

Since cutting is carried out with a sharp knife, which is constantly moistened with soapy water, oil, or at least water.

When cutting, it is best to pull back the piece to be cut to reduce the resistance to the knife.

Such a procedure is indispensable in the manufacture of various homemade products from tires, starting with flower beds of various designs and ending with original garden figures and sculptures.

A well-sharpened strong knife (in the sense of the handle is thicker than a table knife). Pierce the sidewall with a knife and forward a little wetting the knife in water (you can do it in the working off, but then try not to get the knife handle soiled. it will slide)
I made myself a container for water and cut a balloon from K-700 with a knife quite successfully. And balloons from cars are generally easy. If only the cord is cut, then for the metal of the knife.

A sharp knife and lubrication with glycerin, you can use perfumery. it slides like butter and then can be easily washed off with water. The method is recommended in the “Chemist’s Handbook” for cutting rubber plugs, and they are very hard.

thank!
I realized that it is better with a knife!
I’ll try today.

It is ideal to cut with a vibrating knife, with lubrication just do it quickly, it is better to use silicone lubricant. Only if there is a metal cord, then the knife instantly becomes blunt and stops cutting, metal cord only with a grinder

If for the purpose of cutting the tread. then with special tungsten staples. in shape like stapling and with a special rectifier the result is like from the factory.

This is exactly what I was doing 15 years ago. 🙂 In the garage somewhere, there should still be a soldering iron tip with a U-shaped sharpened tip implanted in the copper from some cool steel.

You need to cut with a JAWS, a coarse saw, a grinder is much worse, it cuts more slowly and the stinks are worth being healthy and the klzhuh will be jammed all at once. Checked;)

You need to cut with a JAWS, a coarse file,

Many thanks!
over, it is immensely a coarse file with a large tooth. At first I tried with a file on metal with a fine tooth (I cut the tire along the tread, and then there was a metal cord, then-oh-very little such wires :), but there are a lot of them: confused :). A file for metal with a fine tooth cuts wires, things go slowly, the file sits down quickly. And a file with a large tooth. breaks the wires, things are much more fun. It took 2 large-toothed files and 10 minutes to strip the tire. Protruding wire rags are perfectly sanded together with rubber with a grinding (thick) grinder disc.
