of the macro cutting force is small, heat cutting, will not change the surface deformation and extrusion of chemical/electrical properties, so the machining accuracy and surface quality are good. Compared with other material removal process, ultrasonic grinding device can achieve higher precision and surface finish. In most of the ultrasonic grinding equipment, can obtain the average surface roughness is 0.50 microns. Use the appropriate method, can get 0.25 microns of surface roughness.
