DEVELOPMENT OF THE LOAD COMPENSATOR FOR CYLINDRICAL GRINDING MACHINES.

This paper deals with the development of a high precision, high productivity cylindrical grinding machine with a load compensator which offsets the grinding force at the working point on the workpiece. The proposed compensator is mounted on the bed against the workpiece opposite the grinding wheel. The load compensator supports 98. 5% of the load and decreases the deflection of the workpiece held by the centers and loaded with 30 kg at its midpoint from 34 to 0. 3 mu m. That is, the apparent stiffness is improved from 0. 9 to 100 kg/ mu m.
