The utility model is suitable for a metalworking field provides a metal processing facility, including frame, drive arrangement, transmission, anchor clamps to and die set, transmission include gear and with the gear engaged with rack structure. Adding man -hour to the metal, will treat that the less one end of diameter is made into to the one end of machined part to it is fixed to pass for the die set anchor clamps with it, drive arrangement passes through transmission and drives the anchor clamps motion to to treat the machined part pulling, process die set treats the compression of machinedpart, makes and treats that the diameter of machined part reduces. The utility model discloses still be equipped with the motor with program control to control mold moves, through wheel and rack matched with transmission, makes metal processing facility avoid beginning processing and finish the shake phenomenon with man -hour, and transmitting movement is more accurate reliable, and program control's motor can make with not needing frequent manual operation man -hour, the one -step refining shaping.
