TC 9-524 Chapter 5 GRINDING MACHINESG rinding is the process of removing metal by the applicationof abrasives which are bonded to form a rotating wheel. Whenthe moving abrasive particles contact the workpiece, they actas tiny cutting tools, each particle cutting a tiny chip from theworkpiece. It is a common error to believe that grindingabrasive wheels remove material by a rubbing action; actually,the process is as much a cutting action as drilling, milling, andlathe GRINDING machine supports and rotates the grindingabrasive wheel and often supports and positions the workpiecein proper relation to the GRINDING machine is used for roughing and finishing flat,cylindrical, and conical surfaces; finishing internal cylindersor bores; forming and sharpening cutting tools; snagging orremov

wheel is provided with an adjustable table tool rest and an eye shield for protection. On this machine, the motor is equipped with a thermal over-load switch to stop the motor if excessive wheel pressure is applied thus preventing the burning out of the motor. The motor revolve at 3.450 RPM maximum to
