The surface grinder opens up new possibilities because it could allow you to harden the things you make and machine them to a much closer tolerance. A surface grinder is an outstanding cut-off the instrument for reducing toughened shafting. The material used in surface grinding is 0.25 to 0.50 mm. Surface grinding is best if used for flat cutting.
