action of grinding machine

Grinding - 2: Cutting ActionTo be successful with grinding, it is necessary to understand some basic principles. Grinding uses a method of material removal called abrasion . Rather than cutting like a lathe bit, the material is slowly worn away because the abrasive is harder than the material being ground. In truth the grinding wheel acts like many.action of grinding machine,Grinding - SMEGrinding employs an abrasive product, usually a rotating wheel brought into controlled contact with a work surface. ... honing stones rather than a grinding wheel provide the abrasive action. Electrochemical action removes about 90% of the workpiece metal; the honing stones cut most aggressively on high or tight areas.
