ABSTRACT:
A grinding machine for workpieces having pairs of surfaces which are disposed opposite each other and each of which must be treated by the grinding wheel has one or two inverting heads each of which can removably receive one end portion of a workpiece so that the two surfaces of the workpiece remain exposed. The inverting heads can be turned in synchronism through 180 degrees between first positions in which the first surface of the workpiece can be treated by the grinding wheel and second positions in which the grinding wheel can treat the second surface of the workpiece. The inverting heads are further movable to intermediate positions in which a finished workpiece can be replaced with a fresh workpiece. Several workpieces can be accumulated into a stack which is inserted into a cassette and the latter confines the stack during introduction into, movement in and evacuation of stacked workpieces from the grinding machine. The inverting heads are turned by pairs of arms which are articulately connected to the respective inverting members and to a work support which is movably installed in the frame of the grinding machine. The workpiece or workpieces rest on the support during treatment of their surfaces by the grinding wheel.
