The main components of resin grinding wheels are abrasives, resins, wetting agents, etc. They are characterized by finer particle size, higher hardness, uniform and dense internal structure, regular appearance, and precise size. Due to the elasticity of the resin grinding wheel, the pressure generated on the steel ball during the grinding process is relatively small. Under similar grinding conditions, the steel ball processed using resin grinding wheel instead of grinding process has higher accuracy, better surface quality, lower vibration value, and better silencing effect after the bearing is assembled. In addition, resin grinding wheels have high grinding efficiency, and their production efficiency is more than twice that of cast iron discs. Although the price of resin grinding wheel is higher than that of cast iron disc, its processing efficiency is high, the durability of the grinding wheel is high, and its comprehensive cost is even lower than that of cast iron disc grinding. At the same time, the resin grinding wheel special grinding fluid (oil) is relatively environmentally friendly, and the surface of the processed steel ball is easy to clean.
