- the automatic handling of the workpiece during feeding and discharging of the workpiece can be simplified and at the same time a good hold of the particular ferromagnetically executed workpiece can be achieved in the holding device.
- the holding device has a replaceable adapter for receiving the workpiece, wherein the adapter is designed in particular to receive more than one differently shaped workpiece.
- the Adaper can be easily replaced, so that the workpiece spindle can be easily and inexpensively adapted to other workpieces to be produced.
- the adapter for different workpieces adapted functional surfaces have to accommodate more than one type of workpieces can.
- a lateral surface for a workpiece with a smaller inner diameter project more strongly in the axial direction than a lateral surface for a workpiece with a larger inner diameter.
- the retaining device has retaining shoes designed as a magnetic shoe for tensioning the workpiece in the retaining device.
- the holding shoes can form a tray on which the workpiece can be stored before the holding device can be extended for receiving the workpiece.
- the holding shoes may preferably form an axial stop for the workpiece and / or exert a sufficient holding force on the workpiece, so that the holding device does not push away the workpiece in the axial direction during extension.
- a locking device is provided for holding the spindle.
- the spindle lock can be released so that both the workpiece and the grinding wheel can rotate.
- the invention further relates to a magnetic outer cylindrical grinding machine for cylindrical grinding and surface grinding of annular workpieces, with a workpiece spindle according to the invention for holding the workpiece during grinding, wherein a first grinding wheel for cylindrical grinding of a radially outer circumferential surface of the workpiece and a second grinding wheel for surface grinding a first end face of the Workpiece or a grinding wheel is provided both for cylindrical grinding of the radially outer surface of the workpiece as well as for surface grinding of the first end side of the workpiece.
- different grinding wheels or a common grinding wheel can be used.
- a feed arm for feeding a plurality of separated workpieces into the holding device, wherein the feed arm has a movable loading mandrel for displacing the workpiece, wherein the loading mandrel can be positioned in the axial direction in front of the spindle and / or in front of the holding device.
- the feed several workpieces to be ground can be inserted, which can be separated by means of a singulator.
- the individual workpiece can be picked up by the loading mandrel and, in particular, positioned in front of the holding device within a plane running perpendicular to the axial direction of the tool spindle.
