摘要

A grinding wheel assembly 27 comprising an outer wheel part 22 and an inner sleeve 26 which has an inner peripheral surface forming a mounting reference surface 23 by means of which the grinding wheel 27 is mounted for rotation on a shaft 29. The outer peripheral surface of the part 22 has an abrasive layer 21 and the outer peripheral surface of the sleeve 26 is formed with a pulley part 25 through which the grinding wheel is rotated. The grinding wheel assembly is mounted on a machine base 30 by clamping both ends of the fixed shaft 29 in split support arms 30 min . By this arrangement the assembly can be transferred between machines without introducing errors in the mounting position of the grinding wheel 27.
