Grinder with additional movement has grinding mechanism removably attached to grinding shoe movable by actuator with horizontal and vertical movements parallel and normal to surface

摘要

The grinder has a grinding mechanism (6) removably attached to a grinding shoe (1) that is movable by an actuator (2) with at least one horizontal movement (H) parallel to the surface. The movement also has a vertical component (V) that is perpendicular to the surface. The vertical movement is essentially sinusoidal against time.
