Abstract
There is provided a printed board machining apparatus that is capable of improving machining efficiency without hampering machining accuracy. The printed board machining apparatus includes a pressure foot which is provided with a port whose one end is opened at a lower surface of the pressure foot facing a stiffening plate, and whose other end is connected to a compressed gas source to blow out gas from the port at a pressure which does not interfere with the pressure foot pressurizing the stiffening plate and printed boards in machining the printed boards. It is noted that the gas is blown out during a period of time at least when the pressure foot and the stiffening plate are moving relatively in the horizontal direction.
