Method for changing a tool or a workpiece (300) on a machine tool (200), wherein the tool or the workpiece (200) is held under tension in a tool or workpiece holder (220) by means of a clamping ram (100), comprising the following steps:
- gripping the tool or workpiece (300) held under tension in the tool or workpiece holder (220) with a first handling unit,
- moving the arm (20) of a device (10) for handling a clamping ram (100) in a spatial direction (X) until the contact element (31) of the fastening unit (30) bears against the clamping ram (100),
- pulling out the clamping ram (100) by moving the arm (20) back in the spatial direction (X) until the clamping ram (100) is completely pulled out of the hole (310) of the tool or workpiece (200),
- removing the tool or workpiece (300) by means of the first handling unit,
- supplying of a new tool or workpiece (300),
- retracting the clamping ram(100) by moving the arm (20) with the clamping ram (100) in the spatial direction until the collar (112) of the clamping ram (100) bears against the new tool or workpiece (300).
