ABSTRACT:
A dresser apparatus for dressing a grinding wheel to a desired cross sectional shape, the apparatus including a dresser frame connected to a stationary dresser base, and a slider block slidably connected to the dresser frame. A follower frame is mounted to the slider block for sliding movement with respect to the slider block in a second, substantially vertical direction. Linear actuator means are disclosed for causing the slider block to slide in the first direction with respect to the dresser frame. A cam is provided, corresponding to the desired shape of the grinding wheel, and a cam follower is attached to the follower frame and postioned thereon so as to bear on the cam surface. In one embodiment the cam follower causes the follower frame to move in the second direction according to the shape of the cam surface while the linear actuator means moves the slider block in the first direction. In another embodiment, directed to dressing wheels with a flat or reverse angled surface, a second linear actuator provides the vertical movement. A grinding wheel dressing tool is affixed to the dresser arm and positioned so as to bear on and dress the grinding wheel in conformity with the shape of the cam surface. The dressing tool is attached to the dresser arm, and the cam follower to the follower frame, at an oblique angle with respect to the grinding wheel axis.
