Machine tool with a limit stop device and method for operating the machine tool

摘要

The method involves moving a stop finger (18) of a stop device (15) by a travel drive (23) along a movement path in direction to the processing region into a stop position (43). The stop finger is continuously checked by a monitoring device (38), whether an obstacle is present in the movement path of the stop finger. The force for the return movement is provided by a retraction device (29), which is independently formed from the travel drive. A fast retraction movement is executed accurately in a direction. An independent claim is included for a machine tool with a finger support.
