Abstract

The present invention relates to a spindle apparatus 100 for use on a numerically controlled machine tool, which spindle apparatus 100 has the following: a spindle housing 1, and a spindle shaft 15 which is mounted in the spindle housing, the spindle apparatus 100 having, furthermore, an electrically earthed section 4 which holds at least one rod element 20 which comprises an electrically conductive material, and the at least one rod element 20 being arranged in such a way that it makes contact with the spindle shaft 15 so as to bear tangentially against an outer circumference of the spindle shaft 15.

Description

technical field [0001] The invention relates to a spindle device used on a numerically controlled machine tool. Background technique [0002] Machine tools such as milling machines, lathes or grinding machines are currently state-of-the-art in the field of precision production of workpieces. In the case of machine tools, precision and reproducibility have been increasing over the past few years; firstly, through drives that can be driven very precisely, and through very precise measuring systems that are monitored using a wide variety of parameters The production process, and thus constantly provides feedback to the controller about the actual state of the machining operation. [0003] DE 10 2013 201 328 A1 discloses a machining unit for machine tools which detects, by means of axial and radial measuring sensors, the movement of the spindle axis, which can be caused by debris adhering to the cutting surface or from previous machining processes. other impurities to occur. ...
