Abstract

The invention relates to a hard finishing machine (1). The machine has one tool (4) which is arranged on a tool spindle (3) and a rotary table (5) with an axis of rotation (6) which is aligned vertically, and a workpiece spindle (7) arranged on the rotary table (5) which carries the workpiece (2). To increase the flexibility of the machine, the rotary table (5) has a first rotational position (I) in which the workpiece (2) can be machined by the tool (4), a second rotational position (II) where the workpiece is loaded on the workpiece spindle (7) at a first station (8), and a third rotational position (III) where the workpiece is unloaded at a second station (9).
