HELICAL POT BROACHING MACHINE ABSTRACT OF THE DISCLOSURE A helical pot broaching machine has a pot broach mounted to a base support structure. Means for rotating a part while it is being pushed through the pot broach is mounted in- line with the pot broach and is connected to a driving piston mounted in-line with the rotating means. The rotating means includes a helical nut housing mounted on the inlet of the pot broach and a threaded helical lead bar connected to the driving piston at one end through a swivel joint. The lead bar has a collet attached to the other end which attaches to a part at the inlet of the pot broach. As the piston vertically pushes the lead bar and attached part through the pot broach, the helical nut imparts rotary motion to the lead bar causing the part attached thereto to be also rotated as it passes through the pot broach.
