Abstract
In a machine tool with at least two axes of movement (2, 7) defining, respectively, the mobility of a first function-supporting unit (1) and of a second function-supporting unit (5), only the first function-supporting unit (1) is provided with its own servo drive, while the second function-supporting unit (5) is driven by the movement of the first function-supporting unit (1) through a coupler unit (13) that can be switched between an engaged and a disengaged state.
Claims23
Machine tool with a base, said machine tool comprising:
- a first and a second axis of movement (2, 7),
- a first function-supporting unit (1;
- 24) which by means of a first displacement-actuator unit powered by a drive motor responsive to controls is enabled to move relative to the base in accordance with a first displacement path corresponding to the first axis of movement (2),
- a second function-supporting unit (5;
- 26) which by means of a second displacement-actuator unit is enabled to move in accordance with a second displacement path corresponding to the second axis of movement (7),
- wherein the second displacement-actuator unit comprises a first coupler unit (13;
- 32) which can be switched between an engaged and a disengaged state, said second displacement-actuator unit also comprises a drive-input section which in the engaged state of the first coupler unit (13;
- 32) is enabled to be driven by the movement of the first function-supporting unit (1;
- 24) as the latter is being moved along a displacement path corresponding to the first axis of movement, and said second displacement-actuator unit further comprises a drive-output section which is driven by the drive-input section and which drives the movement of the second function-supporting unit (5;
- 26) along its second displacement path.
