Description:

Abstract:

A grinding wheel energy absorbing apparatus wherein a grinding machine wheelhead carries both a grinding wheel within a grinding wheelguard and the grinding machine base is fitted with a rail and the grinding machine wheelguard is fitted with an extruder plate having uniquely configured extruder holes therethrough, and an extrudable jerk block is disposed between the rail and the extruder plate, such that during the grinding wheel breakage, relative movement of the wheelguard to the machine base causes the extrudable jerk block to be forced through the extruder plate and energy is thereby absorbed.
