Method for operating a cogging or profile grinding machine and cogging or profile grinding machine

摘要

The method involves accommodating a grinding tool (4) on a tool spindle (3) of a gear or profile grinding machine (1). Two workpiece spindles of the machine are temporarily driven to the tool spindle for cooperation of a workpiece with the grinding tool. The workpiece spindles are pivoted around respective rotation axes (7, 8) for movement from a grinding position (I) to a loading position (II), where the workpiece spindles are rotated independent from one another. The rotation axes are arranged parallel and at a distance to one another. An independent claim is also included for a grinding machine for grinding a workpiece.
