    Mostly grinding is the finishing operation because it removes comparatively little metal about 0.25 to 0.50 mm in most operations and the accuracy in the dimensions is in the order of 0.000025 mm. grinding may be of two types 1. Rough or non precision grinding where the work is held in operator s hand.
