The invention relates to a method for the grinding of a profile () of a workpiece () with a gear or profile grinding machine (), wherein the profile () which has to be ground is successively at first ground during a roughing operation with a roughing grinding tool () and is afterwards ground during a finishing operation with a finishing grinding tool (), wherein a stock of the profile () which has to be removed is ground by the roughing and the finishing operation, wherein the roughing grinding tool () and the finishing grinding tool () are arranged coaxially on a common tool spindle () or on two separate tool spindles and wherein a translational movement is created between the grinding tools () and the workpiece () in a direction of a first axis (x) for carrying out a grinding stroke. To improve the cost effectiveness and the quality of the grinding process the invention is characterized in that the at least one tool spindle () or the workpiece () is swiveled around an axis (A) of rotation which is directed in the direction of the first axis (x) by a predetermined angle (&#x3b1;) during the execution of the roughing operation or the finishing operation from a basic position (I) into a swivel position (II) in such a way that the grinding tool () which is not in operation can be passed over the profile () to be machined without collision.

Method for the grinding of a profile of a workpiece

The invention relates to a method for the operation of a gear or profile grinding machine () for the grinding of pre-geared or pre-profiled workpieces (), wherein the machine comprises at least one tool spindle () which can carry at least one grinding tool () and wherein the machine comprises at least two workpiece spindles () which can at least temporarily be driven to the tool spindle () for cooperation of the workpiece () with the grinding tool (). To improve the ratio between primary processing time and secondary processing time the invention proposes that the at least two workpiece spindles () are pivoted around a respective axis of rotation () for transportation from a grinding position (I) to a loading station (II) and vice versa, wherein the rotation of the two workpiece spindles () takes place independently from another. Furthermore, the invention relates to a gear or profile grinding machine.

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