Can I cut rubber with an angle grinder??
Yes! You take a piece of pipe d10 and sharpen the edge with an angle grinder. Then you put this piece of pipe on your rubber and tap (you can also use an angle grinder if you do not feel sorry) on the pipe after moistening the rubber with water until the washer completely falls out. all this is called a puncher. Mm-hmm.
Thin rubber can be neatly cut with a knife or large scissors. The most important rule to remember is to stretch the rubber well. If the rubber workpiece is not stretched when cutting, the blade of the cutting tool will be severely clamped.
How to properly cut or drill rubber
Modern industry produces a variety of different types of rubber, used in the most unexpected industries. Quite simply and quickly you can find the right rubber gasket or the necessary rubber blanks at the nearest bazaar. However, if you still need to make a rubber product with your own hands, then you will need a couple of simple tips on how you can easily and accurately cut a rubber.
Rubber, there are quite a variety of properties, ranging from a very flexible and quite pliable material and ending with a resilient strong rubber plate. You can find all kinds of uses for rubber, such as cutting a proper-sized plumbing gasket, a heel for boots, or a non-slip base for a glass surface. Many people carve all sorts of animals from car tires, swings, or make interior objects. You can make flowerbeds from car tires, but to do this you need to know how and what to cut a car tire with.
The secret is very simple, in order to accurately and simply cut a piece of rubber, you will need a sharp knife, and, of course, ordinary water.
A piece of elastic rubber, a sharp knife and water.
First you need to outline the line for the trimmer of the cut (for me it was enough just to set the blade of the knife evenly).
It becomes quite difficult to cut through thick rubber with the knife as the blade goes deeper into the rubber. Rubber begins to get viscous, and if you overdo it then the rubber can even melt. To avoid it and to help the knife go through the rubber like oil, you need to moisten it with water (not oil, no oil in any case).
Rubber becomes slippery when wet, and the knife blade will not get stuck or melt the rubber, so you get an even and high-quality cut without much effort.

How to make a round hole in rubber:
Sometimes you need to cut circles out of rubber, for example for non-slip legs for a stool, heels, or for pads between two panes of glass. In order to cut circles from the rubber of an even shape you need to pick up a metal tube of suitable diameter, you also need a suitable diameter of the tube piston.
You need to sharpen the edge of the iron tube with a sharp file or file.
Once you have sharpened the tube, you need to insert it in a drill chuck, moisten the rubber with water and just start drilling holes with a piece of wood.
Drilling the round rubber spacers
With such a simple device and water, you can drill as many smooth, accurate rubber circles as you want (I use them to make non-slip legs for devices). The sharpened tube operates on the drill principle, but as you drill the circles it fills them, and in order to get them out and need a special piston. You then just push the rubber circles out of the sharpened tube.
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 the circle, using a sharpened tube, than the classic way. with a drill. However, if you need to drill rubber with a drill bit, it is also quite simple to do with a sharpened drill bit, and periodically dipping the drill bit in water.
Rubber should be drilled at low speed and periodically wetting the cutting edge. But if you want to drill a big block of rubber at high speed, you should immerse it in water completely.
Drilling rubber in water with a drill bit.
In the most extreme case, holes in thin rubber, as well as in plastic, can be melted by heating with a lighter shank of the drill or an iron tube.
The main thing is to be careful when working with red-hot metal. Also remember that rubber can release toxic substances when overheated, so melt the holes under a hood or in a well-ventilated room. Follow all safety rules even when drilling rubber.
How to cut a tire?
Hydraulic cord puller, “DS” series.Hydraulic machines of DS series are designed specially for tear out (pulling out) thick bead wire from car tire planting rings.
Removing a bunch of thick wire is necessary in the initial phase of any mechanical processing of tires. This operation is performed to extend service life of expensive cutting elements of a line on crushing tires into crumb.You can do without this stage, but in this case the expensive equipment will not serve long.
When tearing out the cord on a DS series machine we get a clean bundle of metal bars which are accepted by the scrap metal recycling centers. And this is additional earnings for the disposal company.
An alternative to ripping out thick bead wires is an older method. cutting out rings with a bunch of cords inside rubber casing, using a “bead cutter”. However, there is a question of disposal of cut bead rings. they need to be recycled somehow, and it’s up to 10% of all tires.
If the cut rings are recycled, then you need an additional machine to squeeze the wire from pre-cut rings such as “GSB-280”. But that’s two operations and a waste of time, additional workload of workers, not to mention the fact that one machine to process GSB-280 rings is more expensive than the Cord Cutter “DS”, has higher power consumption and installed capacity of 15 kW / h. The energy cost of the technology “cut side rings, then squeeze out the wire” is about 15-20 kW / hour. Starting power of DS machine from 5.5 to 7.5 kW (depending on model), and average power consumption is 50% lower due to part load and cycling.
DS” machines are designed specifically for the Russian market and intended for tire recycling of both foreign and domestic manufacturers. Such machines of foreign production cope very badly with the task of pulling cords from local tires and are only suitable for imported wheels. The problem with foreign counterparts is that they often do not have a clamp that helps prevent wire from slipping when tearing.
The DS machine can be used as part of any technological line for recycling tires, as well as standalone equipment at tire reception points.This machine is designed to replace the outdated technology of cutting landing rings, so more and more plants for recycling tires into chips are turning to this method of primary cutting of tires.
This machine has a higher performance on light tires than the model DS-500 (universal for trucks and passenger cars) by about 25%. It is reasonable to use the DS-300 machine in tire recycling lines, together with the DS-500 and at tire repair shops.

How to make a tire steadier on the road. the basics of the slicing process
Reduced tread depth reduces the traction of the tire, so the existing grooves must be deepened without widening them to improve stability. For this purpose you need to find a special attachment for regrouper or make a self-made knife for car tires and truck treads.
If tires are sliced with a tire cutter, the tool moves from the center of the tire tread to its edge. The position of the elbow must be controlled. it must remain in a plane parallel to the contact patch. If you raise or lower your elbow while cutting, there will be an extra dent in the tread or an unselected area.
When cutting thick truck tires or specialty vehicle tires this mistake can be corrected by handing them over to a machine shop. Thin passenger car tires do not forgive such failures. You can ruin a tire with just one awkward movement. That’s why most often owners of old UAZ, ZIL or GAZ tires try to cut tires yourself, but owners of cars would do better to have their tires cut only in a workshop.
Hand cutting
The easiest, cheapest but also ineffective answer to the question: “How to cut a tire??”. is the manual way. Properly cutting a tire at home is next to impossible. If you can still use a sharp knife or metal scissors for thin material without reinforcements, this method is completely unsuitable for thick rubber. Manual processing almost always leads to the loss of marketable appearance of the product and is not used in case of complex stenciling.
Laser cutting makes it possible to obtain a rubber product to complex drawings. But, if we are cutting rubber with a laser, the material often overheats and deforms. The point is that the laser beam produces a hole in the material with a diameter larger than the thickness of the cutting line. So the entry point of the beam goes beyond the contours of the part, which leads to additional material consumption and higher cutting costs. The greater the thickness of the material, the greater the likelihood of damage by thermal effect, spoiling the final appearance of the product. Also, laser cutting causes a partial loss of the insulating properties of rubber when the end face of the material is charred. This disadvantage can be critical for some products, such as rubber insulators.
Plotter cutting
We only cut rubber at our center using Zünd precision cutting plotters with Swiss blades. This eliminates all the disadvantages inherent in laser machining. The plotter eliminates the thermal effect, does not cause charring, and does not change the initial properties of the material. In addition, mechanical deformation is also avoided, i.e.к. The Zünd saw uses vacuum turbines to hold the rubber down.
Swiss plotters have an automatic material nesting system that optimizes the cutting path and digitizes the contour by itself. So the answer to the question “how to cut rubber?”is clear. With the plotter you get a fast and high-quality cut with an accuracy of 0.1 mm, using the entire usable area of the material without overconsumption and deformation.
How to cut tires for a flower bed?
Cutting rubber takes a blade with a reverse tooth made of good steel. If you have to cut the tread, it is useless to do it with a jigsaw or knife. At least not with a regular knife. Blades of special steel can even cut iron cord, but hardly anyone wants to damage such a tool on an old tire.
You can disassemble car rims with a homemade machine in this sequence:
- remove the wheel and place it on the flange of the tire changer, securing it with the clamp;
- Use the narrow end of the tire iron to push the edge of the rubber outside of the disc;
- Complete the removal of the tire by pulling it completely off the rim;
Can you cut rubber with an angle grinder??
Rubber is cut with a good blade knife. do not cut rubber with an angle grinder. For if the disk falls off in the head when it crumbles, and it can crumble. you will no longer be able to create new threads.
Use a utility knife and a heavy, sharp knife to cut along the side walls. The side walls have no metal reinforcement, only heavy reinforcing nylon or composite cords, so you can cut them with a knife or a heavy utility knife. Insert the tip of the knife in the cut along the side walls.

What kind of blade is better for cutting rubber??
The most universal is considered to be a disk for an angle grinder on wood of 125 mm, 150 mm and 230 mm. The 125 mm circle is convenient to use when you need to cut metal rebar and bar. Disc for angle grinder wood 150 mm can not only grind and cut metal, but is able to saw a beam or split a board.
Wet the rubber with water and cut with a knife. Rubber becomes slippery when wet, and the knife blade will not get stuck and melt the rubber, so you get an even and high-quality cut without much effort. A rubber block cut with water.
How do you cut a board??
The board moves at an angle to its plane, not along the plane, so very smooth edges are obtained. It can be cut with metal scissors, metal hacksaw blades (coarse toothed is better).
For cutting rubber, take a blade with a reverse tooth made of good steel. If you have to cut the tread, it is useless to do it with a jigsaw or a knife. At least with a regular knife. Blades of special steel can cut even the iron cord, but hardly anyone would want to mutilate an old tire with such a tool.
