Abstract
A method and an apparatus for controlling a radial depth of cut of a rotary cutting tool in a machine tool, in particular in a machining center is disclosed wherein an eccentric mechanism for controlling the radial depth of cut of the tip of the cutting tool is not contained in a main shaft as in a conventional machine tool. Instead, it is provided outside the main shaft, and the radial depth of cut of the tip of the cutter is controlled by a tool holder to be automatically changeably fit to the forward end of the main shaft such that a tool holding shaft mounted to the tool holder by means of an eccentric mechanism so as to have the eccentricity relative thereto be adjustable is adapted to be controlled through a depth of cut central shaft passed through the bore of a draw-bar, concentrically disposed within the bore of the main shaft, by means of a servo-motor through a differential gear mechanism and the eccentric mechanism.
