Abstract
A grinding wheel assembly has a support disk centered on an axis and having an outer edge and a pair of axially opposite faces. An annular abrasive ring is juxtaposed with the outer edge, and a flexible hinge formation joins the ring to the outer edge of the disk at one of the faces. An actuator body of controlledly radially variable dimension joins the ring to outer edge of the disk at the other of the faces for deforming the ring and flexing the hinge formation so as to vary a shape of an outer face of the ring radially of the axis. Thus with this system the exact shape of the outer face of the abrasive ring can be controlled remotely. The control can be very accurate, and can be monitored by sensors in a feedback system to ensure exact position of the outer ring surface.
