Abstract
A milling tool for machining cylindrical sections of crankshafts comprises a rotatable tool drum adapted to be mounted so that it surrounds the workpiece and to be driven and which at one end carries an internally cutting, annular primary cutter head and adjacent thereto is formed in its shell with apertures for the removal of chips. An internally cutting, annular supplemental cutter head has axially projecting claws and is detachably but rigidly secured to the primary cutter head and is axially supported against the latter by the claws. In such tool, a satisfactory removal of chips is ensured, and the supplemental cutter head can be simply and quickly removed to convert the multiple cutter tool to a single cutter tool.
Claims3
A milling tool for machining cylindrical sections of a workpiece, comprising
- (a) a rotatable tool drum adapted to be mounted so that it surrounds the workpiece to be machined and to be driven, the drum having a shell formed near one end with apertures for removal of chips,
- (b) an internally cutting, annular primary cutter head peripherally secured to the shell at the one end, the primary cutter head having a first, inwardly directed end face and a second, outwardly directed end face, and
- (c) an internally cutting, annular supplemental cutter head including axially projecting claws detachably secured to one of the end faces of the primary cutter head, the claws supporting the supplemental cutter head on the primary cutter head against axial movement in relation thereto.
