Efficient way mirror grinding, ELID widely used

In various optical systems, the high reflection mirror has been widely applied, which fused silica, silicon, silicon carbide, and glass materials such as the most popular in some applications where very strict, with nanometer-scale surface roughness submicron form accuracy and low damage optical parts is very much needed as efficient mirror grinding method ELID (ELID) grinding is widely used in hard,  cubic boron nitride  such as processing mirror grinding, grinding after cutting the shape of the workpiece can get better accuracy and surface roughness, but will produce subsurface damage and abrasive wheels . these defects must be in a subsequent process for using free abrasive finishing process in recent years the development of magneto-rheological finishing Technology (MRF) is a micro-injury can reduce the surface, dents or scratches certainty optical parts processing methods. article analyzes and MRF finishing grinding mechanism and characteristics.
