1. A device for correcting the position of at least one element of a machine tool, comprising:
a first machine tool element; a second machine tool element; and at least one compensation element wherein the at least one compensation element is located between the first machine tool element and the second machine tool element, arranged to alter an adjustment travel between the first and second machine tool elements, and arranged to pivot one of the first and second machine tool elements relative to one another about a pivot axis at a joint connecting the first and second machine tool, wherein
the machine tool is a milling machine having an open frame structure, the open frame structure including:
a first structural part having at least one spindle with a spindle axis and a tool configured to be driven about the spindle axis,at least one second structural part having at least one clamping device for at least one workpiece, at least one of the first and second structural parts includes the first machine tool element, the second machine tool element and the at least one compensation element in the respective structural part, and an inclination between the first and second structural parts is adjustable by actuation of the at least one compensation element,
the at least one spindle axis is aligned in a tool clamping plane perpendicular to the spindle axis,the at least one clamping device for the at least one workpiece is aligned in a workpiece clamping plane,the tool clamping plane and the workpiece clamping plane are aligned essentially parallel to one another, andadjustment of the inclination the first and second structural parts adjusts an inclination between the tool clamping plane and workpiece clamping plane,the second structural part includes the second machine tool element,the second machine tool element supports the at least one clamping device,the at least one compensation element includes a plurality of compensation elements disposed between the first and second machine tool elements,the joint is disposed on a side of the second structural part facing the first structural part and is a play-free flexure bearing,the plurality of compensation elements are disposed on a side of the second structural part opposite from the joint, andtwo of the plurality of compensation elements are paired and arranged at a distance from another two of the plurality of compensation elements,the device further comprising a machine-internal measurement system arranged to measure at least one of the inclination and a change in the inclination for use in determining a magnitude of a change in adjustment travel of the plurality of compensation elements required to maintain the inclination between the tool clamping plane and the workpiece clamping plane at a predetermined inclination. |
