PURPOSE: A device of a mobile cut/hole metallic frame for producing a side frame of a truck is provided to reduce the time of exchanging the metallic frames to minimum and to improve the productivity of the press operation by making the metallic frame possible to be moved freely with that the ball screw axises are rotated by driving motors. CONSTITUTION: The device of the mobile cut/hole metallic frame for producing the side frame of the truck includes a holder(50), metallic frames(70a, 70b), a control box(63), motors(59, 61), ball screw axises(55, 57) and a supporter(53). The metallic frames(70a, 70b) are installed on the holder(50) and are moved according to the kind of cars. The control box(63) inputs the control value. The motors(59, 61) are driven according to the control value of the control box(63). The ball screw axises(55, 57) are connected to the motors(59, 61) and rotated. The supporter(53) supports the ball screw axises(55, 57).
