摘要： A grinding wheel support, for instance of a large gear grinding machine, moves up and down during the grinding operation in a non-horizontal guide and is driven by a linear motor which does not possess any self-locking action, for instance a piston-and-cylinder arrangement which is powered by a pressurized oil pump. A brake retains the grinding wheel support in its rest position. During the transition from the rest position into the position-regulation mode the grinding wheel support must not carry out any uncontrolled or undesired movements. Therefore, the grinding wheel support, starting from the time that it is placed into operation out of its rest position, is allowed a certain upward movement play, in order to render possible a surge-free placement into operation of the actual position regulation operation of the position regulator. For this purpose a position measuring system measures a starting position-actual value in the rest position, to which there is added a part of the movement play by means of a set value former, in order to thus define a starting position-set or reference value. The position regulator then controls the pump until the grinding disk support has reached the starting position-set value under the action of the linear motor. At this point in time the brake is released and there can begin the actual position regulation operation.
