ABSTRACT:
A camshaft shaping machine that is capable of providing a camshaft shaped with a cam surface inclined with respect to the cam axis is disclosed. The machine includes a pair of work heads (2) for clamping a camshaft workpiece (4) at its opposed ends rotatably about a longitudinal axis of the workpiece; an X-axis slide (8) movable along an X-axis that extends horizontally in a direction parallel to the longitudinal axis of the camshaft workpiece (4); and a Y-axis slide (11) movable along a Y-axis that horizontally extends in a direction orthogonal to the X-axis. An indexing table (13) is mounted on one of the X-axis and Y-axis slides (8. 11) so as to be turnable about a turning center (0) in a horizontal plane to angularly index and position, relative to the camshaft workpiece (4), a milling cutter (21) that is rotatably supported on a cutter head (20) to angularly mill the workpiece and thereby to permit an inclined cam surface to develop therein. The cutter head (20) is mounted on one of the Y-axis slide (11) and the indexing table (13) and operatively associated therewith.
