The spindle of milling cutter 6 runs in fixed bearings. Cam blank 3 and end cam 5 are rotated by a drive through meshing gears 1 and 2. Axial motion of cam blank 3 with slide 4 is obtained by profiled inverse end cam 5 which contacts fixed bar 7. Weight 8 holds cam 5 in contact with bar 7. Cam grooves a-a of various shapes can be milled by properly designing the working surface of cam 5 and by clamping bar 7 in various positions with bolt 9.
