Application Scope of Abrasive Belt Grinding

Application scope of diamond abrasive belt

Diamond abrasive belt is particularly suitable for processing hard and brittle non-metallic materials and non-ferrous metals. Therefore, it is widely used in the grinding and polishing of complex surfaces of hard and brittle materials such as stone, building materials, glass, special ceramics, monocrystalline silicon, polycrystalline silicon, jade, silicon-aluminum alloys, hard alloys and other hard and brittle materials. With the rapid development of the construction industry, electronics industry and photovoltaic industry, it will certainly create a bright future for the development and application of diamond abrasive belts and various special-shaped products.

Application scope of CBN abrasive belt

Due to the hardness of CBN second only to diamond, and the advantages of small grinding force, low grinding temperature, high grinding ratio, good chemical stability during abrasive belt grinding, it is particularly suitable for processing tough and hard iron-based alloys such as vanadium-containing alloy steel, cobalt-based alloy steel and other special high-speed steel cutting tool rough grinding and grinding; precision grinding and finishing of heat-resistant steel, stainless steel and high hardness alloy structural steel made of precision parts; because of its small grinding force and low grinding temperature, it is an ideal abrasive for titanium alloy grinding, and it is more suitable for precision grinding and finishing of machine tool guideways, instruments and micro-bearing parts; processing of complex-shaped workpieces (insertion cutter, high-precision gears, cam grinding, blades, etc.); precision grinding of other quenched and hardened tools and grinding of various materials parts with local thermal stress and thermal shock sensitivity.

The superhard material abrasive belt products include annular abrasive belt, sanding disc, grinding sheet, hand polishing block, etc., which can process various shapes of workpieces with high surface quality and precision requirements. Not only the service life is longer, but also the grinding efficiency is high.

Development trend of superhard material abrasive belts

Development of special binders. Due to the different requirements of superhard material abrasive belts in different fields, it will be necessary to develop special binders for specific fields of use.

Research and development of micron-level superhard abrasive planted sand. At present, manual planting sand is used, and its shortcomings are that the uniformity and directionality of the abrasive cannot be effectively controlled. American companies use point glue machines to manufacture resin-glue abrasive belts, which can better solve the problems of uniformity of abrasive distribution and flexibility of abrasive belts, and can save superhard abrasive materials and reduce costs.

Development of high-precision and ultra-precision superhard abrasive abrasive belts. At present, precision grinding usually refers to the processing technology with processing accuracy of 3 to 0.3μm and surface roughness of Ra0.3 to 0.03μm. Ultra-precision grinding requires processing accuracy of 0.3 to 0.03μm and roughness of 0.03 to 0.05μm. Because of the basic characteristics of superhard material abrasive belts, applying them to precision and ultra-precision grinding is one of the main directions in the future.
