ABSTRACT:
A high-precision punch and die apparatus having a stationary frame; a punch movable relative to the frame, the punch including integral pneumostatic bearing surfaces and at least one cutting edge; and a die adjustably mounted to the frame to receive the punch therethrough, the die including at least one cutting edge coactable with the cutting edge(s) on the punch. A pair of pneumostatic bearings are provided to constrain and guide movement of the punch through the die, each bearing having a segmented journal that includes a plurality of journal segments formed with a pneumostatic bearing surface, the journal segments being adjustably mounted, relative to the frame, to receive the punch therebetween so that the bearing surface on each journal segment is in closely spaced relation to an opposing one of the bearing surfaces on the punch. Also provided are means for controllably supplying a pressurized gas to the bearing surface on each journal segment, to facilitate constraining and guiding movement of the punch through the die, and means for effecting such movement of the punch through the die so as to move the cutting edge(s) on the punch into coacting relation with the cutting edge(s) on the die.
