ABSTRACT:
A pneumatic marking tool (35,123) is attached to one of the punch mounting holes (9) of the upper turret disk (3) of a punch press. When the punching striker (13) is moved down to its lower dead point, compressed air is supplied from a compressed air supply unit (103) to the marking tool to move the marking stylus (49, 129) up and down repeatedly at a high speed. At the same time, the work (W) is moved in a two-dimensional way by the Y- and X-axis work driving mechanisms (27, 29) of the punch press, in synchronism with the repetitive marking stylus motion, to engrave characters and/or symbols as a form of gathered dots all under control of the numerical control unit (33). Therefore, it is possible to mark or engrave any required characters and/or symbols without occupying a number of punch mounting stations of the upper turret disk and without the use of any punch press of high punching frequency, thus eliminating the laborious setting work required whenever the plate thickness of the work changes.
