ABSTRACT:
A method and apparatus are disclosed for feeding oil to a turret punch press in which an upper tool is adapted to be repeatedly moved vertically relative to a lower tool formed at the upper end of a cylindrical die. Conventional hand lubrication or the like can be carried out in order to feed lubricating oil to the contact surfaces at which the upper tool and a supporting member therefor make sliding contact with one another. A material is positioned on the upper face of the cylindrical die so as to mask the cylindrical die. Atomized cutting oil is periodically fed to the inside space of the cylindrical die, and is prevented from escaping therefrom due to the presence of the material before punching of the material and due to the extension of the upper tool into the lower tool after punching of the material has been carried out.
