Abstract

A plain grinding machine wherein a grinding unit with a spindle for grinding wheels is reciprocable along the bed and is indexible about a vertical axis to transfer work holders between one or more indexible turrets or a magazine and a socket which is reciprocably mounted on the bed. The spindle of the grinding unit can further carry and rotate a clamping device for a workpiece to be treated by the internal grinding wheel of a holder which is separably secured to the socket. The clamping device can be stored in a second magazine which further serves for storage of one or more tool holders or tools. The grinding unit, the socket and each holder has clamping elements which can separably secure a holder to the socket, to the magazine or to the grinding unit. The control unit of the grinding machine transmits signals for actuation of the grinding unit when the latter is used as a manipulator to transfer holders between the socket and a turret or between the second magazine and the spindle.
