Machine tool, in particular grinding and / or EDM machine and method for replacing a tool assembly

摘要

The invention relates to a machine tool (20), for example a grinding machine and / or an eroding machine (21). The machine tool has a machine base (22) and an axle assembly (23) for moving a tool carrier (25) and / or a workpiece clamping device (26) relative to the machine base (22). On the machine base (22) there is a transport device (75) with preferably exactly two transport places (76) for one tool assembly (27) each. A robotic arm (42) with gripping means (44) is adapted to grip and move either two workpieces (38) or, alternatively, a single tool assembly (27). As a result, a workpiece change with the workpiece clamping device (26) can be carried out directly via the robot arm (42) or a tool module (27) can be picked up and removed from the transport device (75) in the transport device (75). The transport device (75) can be moved out of the working area (A) of the machine tool (20) and into the working area (A) and, in cooperation with the axle arrangement (23) of the machine tool (20), change the tool assembly (27) on Carry out tool carrier (25).
