Abstract: A spindle shaper machine tool successively performs a plurality of operations on a work piece without removal and replacement of cutter heads on the spindle. The cutter heads are superimposed on the spindle, a fluid pressure jack quickly shifts the spindle to align a selected head with a work piece and the work piece is either manually or automatically advanced across the rotating selected tool. In the automatic shaper tool, a collar bearing stop for each cutter head is also provided on the spindle to abut the work piece or a template controlling the cutting of the work piece. The jack can be manually actuated by the operator or automatically actuated at the completion of a cutting cycle. Various combinations of cutter heads and bearing stop sets are mountable on the spindle to perform selected operations such as rough and finishing cuts, heavy-duty and light cuts, cutting and sanding, adding or modifying cuts and the like.

Abstract: A noise reducing cutterhead for planers which includes a cylindrical cutterhead member having a plurality of circumferentially spaced axial grooves therein receiving cutter blades, the blades having an axial length less than the length of the cutter head, the blades being spaced from one another in each groove and the blades in successive grooves being staggered in axially offset relationship, the blades being held in place in the cutterhead by a wedge lock member and being adjustably received in the grooves.
