Verfahren und Vorrichtung zum Bearbeiten von Kurbelwellen o. dgl. Werkstücken

摘要

The invention concerns a method and device for machining the bearing seats of automobile crankshafts or similar workpieces, the workpiece being rotated at approximately 20 to 100 rpm by means of a holder device in which the workpiece is mounted so as to be rotatable, and a tool which is disposed orthogonally to the workpiece being advanced thereto. Bearing seats can be machined economically yet with exceptional quality by advancing a rotary cutter tool, rotating at high speed about its axis, tangentially to the bearing seat to be machined.
