Machine tool for manufacturing and/or processing of screw holes in wheel disk, has rotatable tool spindles to milling cutter for simultaneous circular milling of screw holes in wheel disk

摘要

The tool (10) has a set of rotatable tool spindles to a milling cutter (12) for simultaneous circular milling of several holes, in particular screw holes in a wheel disk (14). Spherical milling cutters are applicable as milling cutters. The spindles are fastened on a common carrier (11) to make them move together. The holes are unilaterally or bilaterally chamfered by circular milling. An independent claim is also included for a workpiece, in particular wheel disk, with a set of holes.
