ABSTRACT:
A machine combines metal rod chamfering and stamping operations into a single machining operation. Cutting the chamfer on the end of the rod is accomplished by a rotating cutting tool affixed to a chuck which rotates with a spindle about an axis co-linear with the axis of the workpiece. Both the chuck and the spindle contain a hollow bore along their rotational axes. This bore holds a stamping rod which is free to move axially within the spindle. A stamping impact unit is located at the opposite end of the spindle which acts upon the opposite end of the stamping rod. At the desired moment within the chamfering operation, the stamping rod is hammered into the end face of the workpiece by the impact unit. The imprint end of the stamping rod functions as a mechanical stop to locate the depth the workpiece is inserted into a clamping collet.
