Manufacturing “long” shafts begins in this cell that has been setup with (2) 4-axis lathes and (2) 3-axis lathe.  This cell is designed to handle low to medium volume production runs of pistons, shafts, or acme lead screws up to 6 inches diameter x 30 inches long.

Once an acme lead screw is processed through this cell, it is moved to a thread grind department consisting of (3) Reishauer thread grinding machines.  The acme thread is ground from solid, deburred, and sent outside to gas or ion nitride.  Upon return, the screw is magnetic particle inspected (NDT), shot peened (as required), finish ground, final NDT, and final inspected.
