<p>: A rotary tool positioning unit for machining workpieces is disclosed having a rotary tool holder and a plurality of slide bearings cooperating with one another in such a manner that the rotary tool holder is capable of independent translational movement in either of two directions perpendicular with respect to one another and capable of independent rotation about either of two axes perpendicular with respect to one another. One of the translational directions is parallel to one of the rotational axes. The unit also includes an eccentric crankshaft cooperating with two slide bearings perpendicular with respect to one another for imparting a reciprocating movement to the tool holder in a direction perpendicular to the longitudinal axis of the tool holder.</p> |
