ABSTRACT:
The present crankshaft milling machine comprises at least one milling slide in which the drive spindle is rotatably supported. A milling tool with axially spaced disk cutters is also rotatably supported in the milling slide and operatively connectable, for example, by a clutch, to the drive spindle. One support bearing of the milling tool is constructed as an axial thrust bearing. The clutch between the milling tool and the drive spindle is constructed to transmit torque moments and it is unable to transmit axially effective forces or loads. The clutch and divided bearing shells permit the exchange of the milling tool including the arbor carrying the cutters as a unit.
