Rough grinding In rough grinding the grinding wheel are used 1. For removing the excess material from casting, forging & weld materials 2. For removing the sharp corners, burrs or other unwanted projections from the work piece. Ø Rough grinding does not give good surface finish & high dimensional accuracy Ø
Precision grinding is used for imparting the good surface finish & high dimensional accuracy to the work piece.
