OSCILLATORILY DRIVEN MACHINE TOOL

摘要

Disclosed is an oscillatorily driven machine tool comprising a tool spindle (34) that is mounted so as to be pivotable about its longitudinal axis (35), a driving motor (14) that is coupled to a hydraulic generator (22) for generating an oscillating fluid flow which drives a hydraulic motor in the form of a rotor motor (30). Said rotor motor (30) drives the tool spindle (34) in such a way that the tool spindle (34) oscillatorily rotates about its longitudinal axis (35). The rotor motor (30) comprises symmetrically arranged rotor blades that are disposed at regular angular distances from each other.
