Ultra-precision grinding
 
Ultra Precision Machining Technology marked a level of state machinery manufacturing industry has a very important role in improving the performance of mechanical and electrical products, quality, longevity and development of high-tech products, and other aspects. Currently, ultra-precision machining is the machining error of less than 0.01μm, surface roughness of less than Ra0.025μm processing, also known as sub-micron processing. Now, ultra-precision machining has entered the nano-scale, called nanofabrication.
 
Grinding or polishing (Lapping or Polishing) is a smooth mirror surface of the workpiece to produce ultra-precision grinding technology, which aims to make the surface roughness and flatness reaches a certain allowable range, often widely used in hard and brittle metal, ceramic, glass and precision machining wafers and other materials surface.
