ABSTRACT:
An apparatus and method for machining and threading the end of pipe or bar stock which uses a pallet shuttle for clamping and locating the end of the stock to be machined and utilizes a lift-and-carry transfer bar system to move the work elements in a horizontal plane in synchronism with the shuttle motion of the pallets from one registry station to the next registry station. Separate idle supports are selectively raised and lowered in a timed relation to carry the work elements on the transfer bar. End location rollers are utilized to position the element axially and to unload the elements. A series of machining stations are positioned at the respective registries to machine first one end of the elements in a series of steps and then the other end of the elements in a series of steps.
