Abstract:
A motor-driven machine-tool unit such as a multi-axis turning head or a motor spindle, having a stator unit and at least one rotor unit that is rotatable about a rotation axis, wherein the rotor unit comprises at least one tool receptacle unit having a tool clamping device that is adjustable in a longitudinal direction of the rotation axis and impingeable with a clamping force, for fixing and bracing a releasably fixable tool, wherein comparatively high requirements are met, in particular, in terms of the accuracy of the machining and/or the reliability in the machining. According to the present invention, this is achieved above all in that at least two clamping force sensors are provided for detecting the bracing of the tool clamping device, in particular the clamping force that is caused in the fixing and bracing.

Claim (Index 12):
A method for clamping a releasably fixable tool in a machine-tool unit, wherein a rotor unit that is rotatable about a rotation axis uses at least one tool receptacle unit having a tool clamping device that is adjustable in a longitudinal direction of the rotation axis and impingeable with a clamping force for fixing and bracing a releasably fixable tool, wherein at least during and/or after the adjustment and the bracing of the tool clamping device that is directed in the longitudinal direction of the rotation axis, for fixing the tool and/or in the case of a fixed tool, at least two clamping force sensors detect the bracing of the tool clamping device,\n wherein clamping force sensors which are configured as follows are used as such clamping force sensors: the at least two clamping force sensors are configured as proximity sensors for detecting a spacing between the rotor unit and the stator unit;\n the at least two clamping force sensors are configured as deformation sensors for detecting a deformation of at least part of the rotor unit and/or of the tool receptacle unit that is generated by the clamping force; \n the at least two clamping force sensors are disposed at mutually dissimilar angular positions about the rotation axis and/or are disposed symmetrically about the rotation axis; \n wherein the at least two clamping force sensors measure the clamping force by way of a deformation of at least part of the rotor unit that runs symmetrically about the rotation axis and is caused by the action of the clamping force, and determine the position and/or alignment of the rotation axis in a machining procedure of the machine tool.
