Traditional methods of cutting tires, such as using electric saws, grinders or pneumatic small-tooth saws, often have many problems.
Not only is it inefficient, it may take a lot of time to cut a tire, and due to the complex wire and fiber structure inside the tire, it is very easy to cause the saw blade to jam or even damage, and the cuts are often uneven.
A large amount of rubber dust will be generated, which not only harms the health of the operator, but also poses a safety hazard of explosion. At the same time, the noise during cutting by the grinder is also very loud, which greatly interferes with the working environment. And it is difficult to meet high-precision processing requirements.
Traditional cutting tools have poor versatility when facing tires of different materials and thicknesses, and often require frequent tool replacement and adjustment of cutting parameters, which further reduces work efficiency. These difficulties of traditional cutting methods urgently need a new, efficient and precise cutting method to solve.
What is diamond cutting wire?
Diamond cutting wire is a great tire cutting tool.Diamond wire is made by electroplating diamond powder particles with uniform distribution density firmly fixed on a high-strength steel wire matrix. The electroplated coating, as a binder, tightly combines the hardest diamond powder with the steel wire matrix to ensure that the diamond powder will not fall off during high-speed cutting; it can withstand the tensile force during the cutting process without breaking.
Advantages of diamond cutting wire for cutting tires:
The diameter of diamond wire is usually very thin, generally between 2-4 mm, which enables it to achieve extremely high precision when cutting tires. The error can be controlled within a very small range. It can cut slices with uniform thickness and precise size, meeting the needs of high-precision scenarios such as tire section analysis.
As the hardest substance in nature, diamond gives diamond wire excellent cutting ability. When cutting tires, its cutting speed far exceeds that of traditional cutting methods. Using a traditional electric saw to cut a tire may take 5-10 minutes. Under the same conditions, using a diamond cutting wire to cut a tire may only take 1-2 minutes.
Diamond wire cutting produces significantly less waste. For example, grinding machine cutting will produce a large amount of rubber dust, which is not only difficult to collect and treat, but also causes serious air pollution and endangers the respiratory health of operators. Wastewater may also be produced, which contains cut rubber particles and other impurities. If it is discharged directly without treatment, it will pollute the soil and water.
When diamond cutting wire cuts tires, it mainly produces more regular rubber blocks and a small amount of debris, which are easier to collect and recycle. At the same time, there is no need to use a large amount of coolant and other chemicals during diamond wire cutting, and no wastewater will be discharged, which is truly green and environmentally friendly, in line with the current environmental protection concept of sustainable development.
How to cut tires with diamond cutting wire:
Preliminary preparation
Before using diamond wire to cut tires, select diamond wire of appropriate specifications. Different tire materials, thicknesses and cutting requirements require diamond wires of different specifications. For example, for thicker engineering tires, you may need to choose diamond wires with slightly thicker wire diameters, larger diamond particles and higher distribution density to ensure sufficient cutting force and wear resistance; while for fine processing of ordinary automobile tires, you can choose diamond wires with thinner wire diameters, uniform and fine diamond particles to achieve high-precision cutting.
At the same time, ensure the normal operation of supporting equipment, including diamond wire cutting machine tools, tensioning devices, cooling systems, etc. The accuracy and stability of the cutting machine tools directly affect the cutting quality. The tensioning device must be able to accurately adjust the tension of the diamond wire to ensure that the diamond wire always maintains appropriate tension during the cutting process to avoid reduced cutting efficiency or uneven cutting surface due to insufficient tension. The cooling system can effectively reduce the temperature during the cutting process, prevent the tire material from being deformed or damaged due to overheating, and extend the service life of the diamond wire.
When fixing the tire, use a special clamp or fixture to ensure that the tire is stable and does not shake during the cutting process. You can choose the appropriate clamp type according to the size and shape of the tire, such as a chuck clamp, a hoop clamp, etc. Fix the tire firmly on the cutting table so that the cutting part is in the best cutting position. At the same time, pay attention to check the firmness of the fixation to avoid the tire loosening during the cutting process, which will not only affect the cutting accuracy, but also may cause safety accidents.
Cutting process
- Setting equipment parameters is an important part of the cutting process. According to the material, thickness and cutting requirements of the tire, reasonably adjust the parameters such as cutting speed, feed speed and tension. For tire materials with higher hardness, the cutting speed can be appropriately reduced to ensure that the diamond cutting wire has enough time to grind the tire; for thinner tires, the feed speed can be appropriately accelerated to improve cutting efficiency.
- The setting of the tension force should be determined according to the specifications of the diamond wire and the performance of the cutting equipment. Usually, on the premise of ensuring that the diamond wire does not break, try to keep the tension force within a stable range to ensure the stability and consistency of the cutting. After starting the equipment, the diamond wire starts to move at high speed, contacts the tire surface and produces a grinding effect.
- During the cutting process, it is necessary to maintain a uniform and stable speed and avoid sudden changes in cutting speed and feed speed. Because the unstable speed will cause uneven cutting force on the diamond wire, thus affecting the cutting quality, there may be problems such as uneven cutting surface and inconsistent cutting lines.
- At the same time, pay close attention to the situation during the cutting process, such as the wear of the diamond wire, the change of cutting temperature, and whether the cutting sound is abnormal. It should be replaced in time to ensure the cutting effect; if the cutting temperature is too high, the parameters of the cooling system can be adjusted appropriately, the flow rate of the coolant can be increased or the temperature of the coolant can be reduced; if the cutting sound is abnormal, it may indicate that there is a problem in the cutting process, such as loose tire fixation, friction between the diamond wire and equipment parts, etc. At this time, the equipment should be stopped immediately for inspection and troubleshooting.
End of cutting
- When the cutting is completed, first turn off the equipment, wait for the equipment to stop running completely, and then carefully remove the cut tire. When removing the tire, be careful to avoid damaging the cut section, because the cut surface is still relatively fragile at this time and is easily affected by collision or scratches, which may affect its quality. After removing the tire, check the cut tire to see if the cut surface meets the requirements, such as the flatness and dimensional accuracy of the cut surface. If problems are found on the cut surface, such as unevenness or burrs, appropriate treatment can be carried out according to the specific situation, such as grinding with sandpaper or secondary cutting.
- Cleaning and maintenance of equipment and diamond wire is also an essential link. Clean the rubber crumbs, coolant and other debris on the surface of the equipment to prevent these debris from accumulating on the equipment and affecting the normal operation and service life of the equipment. At the same time, check whether the various parts of the equipment are loose or damaged. If there are any problems, tighten or replace them in time. For diamond wire, clean the rubber residue and coolant on the surface and check its wear. If the diamond wire is lightly worn, it can be properly repaired and maintained, such as readjusting the tension, cleaning and rust-proofing the diamond wire. If it is severely worn and has reached its service life, it needs to be replaced with a new diamond wire in time to ensure the next cutting operation goes smoothly.
