Grinding apparatus is disclosed with the preferred embodiment being an automatic ice skate sharpening machine. The workpiece is secured to the frame, and a grinding wheel, mounted on a longitudinally moveable carriage, is biased against the workpiece for relative grinding movement. Sensing means are provided for detecting the grinding resistance of the workpiece on the grinding wheel, and control means responsive to the sensing means are provided for regulating the bias of the grinding wheel against the workpiece, in order to avoid chattering.
Grinding apparatus comprising in combination clamping means for securing a workpiece; a grinding wheel and means for mounting said grinding wheel to said clamping means for relative movement of said grinding wheel with respect to said workpiece; sensing means for detecting the grinding resistance of said grinding wheel; means for producing a biasing force for biasing said grinding wheel such that engagement of said grinding wheel with a surface of the workpiece may be controlled; and coupling means, independent of said biasing force producing means and h...
