The resin binder has a higher bonding strength than the ceramic binder, and the manufactured abrasive has higher mechanical strength than the ceramic abrasive. The most common example is the
T41 4 inches cutting disc size. The cutting disc can be used at a higher speed, can accept a larger grinding pressure, and is safer to operate. Therefore, it is widely used in the rough grinding process of steel, car bearings, chemical machinery, construction and other occupations.The cutting disc is attributed to the polymer compound, has certain resistance and elastic deformation, can buffer the grinding pressure, and thus has good grinding effect, excellent polishing effect, and can improve the processing quality of the workpiece surface. With the new resin, it can be made into resin grinding tools of various strengths and functions, which can be used for grinding, rough grinding, cutting, semi-finishing, fine grinding, polishing and other abrasive tools. The cutting disc bond has a low curing temperature and a small shrinkage, and can be made into various abrasive shapes and special requirements. Such as the shape of the grinding wheel, plus the high-speed cutting of the mesh.The cutting disc bond has low heat resistance, and is heated and charred in the grinding process, which promotes the blunt abrasive detachment, reveals new sharp abrasive grains, reduces the heat in the grinding area, and avoids burns on the workpiece; thus, More suitable for surface grinding, etc., but the wear is greater than ceramic abrasives. The cutting disc grinding tool has a short production cycle, the equipment is simply invested less, the capital turnover is fast, and the production efficiency is high, which is conducive to professional production. Generally, the cutting disc abrasive has poor alkali resistance and water resistance, and cannot be stored for a long time. In the case of alkaline substances, the structure of the cutting disc degrades, affecting the strength and hardness of the grinding tool. In addition, the cutting disc grinding tools are expensive and the production environment is poor.The use of cutting discs is very extensive. The grinding wheel is mainly used in the steel industry, for the grinding of steel ingots, billets, steel plates and the appearance of various castings. In terms of output value, it ranks first in all kinds of cutting discs. The high-speed cutting piece is developed on the basis of the general cutting piece according to the grinding process requirement. The speed is 70-80M/S, which has the advantages of high cutting efficiency, good impact resistance and anti-bending function. Now it has been developed from cutting small metal materials to cutting large standard steel and steel plates. The standard of grinding wheels is increasing and the output value is getting bigger and bigger, second only to the grinding wheel. High-speed grinding discs are widely used in the grinding of welds in metallurgy, chemical, shipbuilding and other mechanical processing, finishing casting burrs and metal appearance.There are many standard products for cutting discs, which are used at speeds of 60-80 M/S. They are used in the grinding industry for cars, tractors and bearings. Its outstanding feature is the use of a surface grinding process. It can be made into an abrasive tool such as a gas wheel or a grooved grinding wheel, which greatly improves the grinding function of the grinding wheel. In addition, some resin grinding wheels are also widely used in various industries, replacing ceramic grinding wheels and rubber grinding wheels to varying degrees.
