Grinding Machine With Energy Absorbing Breakage Guard
US Patent:

Filed:
Jun 27, 1975
Appl. No.:
5/590956
Inventors:

Assignee:

International Classification:

Abstract:
An improved grinding machine includes an energy absorbing device which harmlessly dissipates the energy released in the event of a failure of a grinding wheel during a grinding operation. The energy absorbing device includes a plurality of cutters which are mounted on a common actuator plate. In the event of a breaking up of the grinding wheel, the fragments of the grinding wheel inpact against the actuator plate and move the cutters to cut away metal from blocks mounted on the base of the machine. As the metal is cut away, energy is dissipated and the kinetic energy in the fragments of the grinding wheel is harmlessly absorbed.
