grinding machines, bufting machines. and reciprocating surface grinding machines. UTILITY GRINDING MACHINES The utility grinding machine is intended for offhand grinding where the workpiece is supported in the hand and brought to bear against the rotating grinding abrasive wheel. The accuracy of this type of grinding machine depends on the
Initially with the grinding wheel running, a no-load power P NL is dissipated in the spindle bearings and by motor windage. With the grinding fluid switched on and the grinding wheel close to the workpiece, additional power P f is dissipated by grinding fluid drag on the grinding wheel. After contact is made between the grinding wheel and the workpiece the depth of cut builds up and hence the
