2020 wholesale price microgrits- Graphite grinding wheel, resin powder, mirror polishing wheel, roller bearing steel – Kemei

Due to the small expansion coefficient of graphite and its ability to withstand the changes of rapid cooling and heat, it can be used as a mold for glassware. After using graphite, the castings obtained from ferrous metal have accurate size, smooth surface, high yield, and can be used without processing or a little processing, thus saving a lot of metals. In the production of cemented carbide and other powder metallurgy processes, graphite materials are usually used to make the boat dishes for pressing and sintering. Crystal growth of monocrystalline silicon, regional refining vessels, brackets, clamps, induction heaters, etc., are all processed with high-purity graphite. In addition, graphite can also be used as insulation board and base of vacuum smelting graphite, high temperature resistance furnace tube, rod, plate, grid and other components.Graphite grinding wheel is mainly used for ultra precision grinding, polishing and mirror grinding with small grinding allowance. This kind of grinding wheel has good elasticity, high precision and low roughness of the workpiece to achieve mirror effect

It is mainly used for mirror surface polishing and ultra precision grinding, with a surface finish of ra0.01. In addition, it has green silicon carbide micro powder grinding wheel, which is used for fine grinding and ultra precision grinding with a relatively large processing amount. It can be used for external circle polishing, plane polishing, cutting edge grinding of cutters, centerless grinding stone and ink grinding wheel, and micro powder grinding wheel, which can be used for fine grinding and polishing of cylindrical workpieces such as connecting rod, piston rod, piston pin, bearing roller, etc Optical process, welcome to sample orders from major manufacturers.
