This machine is mainly used for grinding polishing of precision optical glass, quartz, crystal, metal and non-metallic high-precision flat components. Machine is equipped with high-power worm gear reducer, large thrust ball bearings. Granite countertops in different environments, different temperatures, a small amount of deformation. The machine is equipped with stainless steel countertops, sink clean and beautiful, easy to clean, and frequency control, the output torque. 
 Workpiece rotation system to increase the driving wheel rotating mechanism played a very good rotation capabilities for processing large parts, and fully meet the processing requirements of high-precision optics.
