ABSTRACT:
In a work feeding device for a plate work processing machine (e.g., a turret punch press), when a ball screw (1) is rotated by a drive motor, a ball nut (103) in mesh with the ball screw and fixed to a worktable is moved in the work feeding direction. Here, the ball screw is divided into a central portion (3) and an outer portion (5). The outer portion (5) thereof is formed of an ordinary material (e.g., steel), and the central portion (3) thereof is formed of a hard material (e.g., cemented carbide) of high longitudinal elastic coefficient. Since the maximum number of revolutions of the ball screw (i.e., the resonance frequency of the ball screw) can be increased, it is possible to move and locate plate work at a high speed, thus realizing a high speed punching processing to improve the working efficiency.
