Abstract
Machining of a hard, brittle and difficultly-machinable workpiece by a grinding wheel made of superabrasive grains. The grinding wheel is rotated at a peripheral speed of 1000 to 5500 m/min., and the grinding wheel and the workpiece are moved relative to each other in the machining direction at a feed speed of at least 30 mm/sec.
