Abstract
In order to improve a device for the non-circular machining of workpieces comprising a machine frame, a workpiece spindle held on the machine frame and operated as C-axis for a workpiece to be machined, a Z-slide displaceable on the machine frame in the Z-direction in relation to the workpiece spindle and having a Z-axis drive, an X-axis drive in the form of a linear motor arranged on the Z-slide for advancing a tool in the X-direction towards the workpiece, and a numerical control system for activating the X-axis drive in correlation with the rotation of the workpiece spindle, such that more precise work results are obtained, it is proposed that the linear motor serving as X-axis drive be a three-phase asynchronous linear motor with a primary part fixedly arranged in the X-direction on the Z-slide and a secondary part movable relative to the primary part.
