Fine Grinding (Polish Grinding)
There may be geometrical uncertainties, scratches and similar faults on grinded surfaces. In some cases, these faults have to be fixed, and the surface integrity should be provided by eliminating tensions. The processes, which are applied to improve the surface quality and to obtain the precise dimensions using special abrasive materials include honing, fine grinding, lapping, polishing. Fine grinding (polish grinding), one of these advanced surface treatment processes which is done if only a better surface quality is required, should be done after grinding process. Therefore, the quality of the mirror polished surface is directly bounded to the quality of the grinding process. The quality of fine grinding is defined by means of surface roughness measurements (Ra, Rz, Rt, Rmax).
Surface Roughness Parameters DIN ISO EN4287, 4288 & 13565-1 / 2
