The hardness of cutting disc is the main characteristic that determines the abrasive properties. Super hard abrasives itself has very high hardness, so the grinding wheel can be processed a variety of high hardness materials, especially ordinary abrasive is difficult to process materials. For example, diamond abrasive tools are used to process cemented carbide, ceramic, agate, optical glass, semiconductor materials, stone, concrete and other non-metallic materials and non-ferrous metals. Satisfactory results can be obtained by using CBN abrasive tools to process tool steels, die steels, stainless steels, heat-resistant alloys, etc., especially to process ferrous metals such as high vanadium high speed steel. The grinding temperature of the super-hard cutting disc is low, which can greatly improve the surface quality of the workpiece being processed, and avoid defects such as cracks, burns and tissue changes.
The cutting discs are made of high strength resin and selected special abrasive. The linear speed allowed by them is large, all of which exceed 50 m/s. Cutting sharp, cutting heat is minimal, the sample thermal impact layer is shallow, thus minimizing interference. The cutting sheet is widely used in the industries of machinery, automobile, ship, metallurgy, chemical industry and so on. Polishing sheet professional grinding general metal, stainless steel, broken fire steel, tool steel construction metal, casting gray iron, hard cast iron metal. This grinding wheel is not easy to burn and heat, cutting speed, high efficiency, durable. It also greatly improves the stress condition of the machined surface of the parts, which is conducive to the extension of the service life of the parts and improves the comprehensive economic index. Ultra-hard cutting pieces wear less, use a long cycle, high grinding ratio, under the condition of reasonable use, can get a good economic effect, especially with ordinary abrasive difficult to process materials, better economic effect!
