    Nov 21 2014 · As the accuracy in dimensions in grinding is on the order of 0.000025 mm in most applications it tends to be a finishing operation and removes comparatively little metal about 0.25 to 0.50 mm depth. However there are some roughing applications in which grinding removes high volumes of metal quite rapidly. Thus grinding is a diverse field. 4.
