Abstract
A machining device for machining crankshafts has a rotationally driven disk-shaped base body with blade inserts arranged peripherally thereon. A first supply line for a cryogenic cooling medium is arranged concentrically with the axis of rotation and is thermally insulated in at least some sections. The tool has a plurality of second supply lines for the cryogenic cooling medium running across the axis of rotation and leading to the blade inserts, the second supply lines each being thermally insulated in at least some sections. A distributor unit connects the first supply line to at least one of the second supply lines for supplying the cryogenic cooling medium to at least one of the blade inserts. The cryogenic cooling medium can be conducted directly to the blade inserts which are engaged with the crankshaft that is to be machined.
