When sucking and holding the sucked work on the suction work holder, air is blown out from a vacuum hole formed on the upper surface of the table to release the suction and float the work, and at the same time, the work of the suction work holder is stopped. The work is delivered to the suction work holder by sucking air from the vacuum hole, and air is ejected from the vacuum hole opened in the suction work holder when the work on which punching has been completed is placed on the mounting portion. The gist is that air is controlled so that the suction is released and the work is dropped, and at the same time, the air is sucked from the vacuum hole formed on the upper surface of the mounting portion and the work is transferred to the mounting portion. (Claim 1).

According to the above technical means, the work feeding means sends the work to the upper surface of the table adjacent to the work feeding means, cuts the work when it reaches a required length, and mounts the cut work on the upper surface of the table. Then, based on a predetermined program, when the moving means is controlled to move in the X and Y directions to suck and hold the work placed on the upper surface of the table, air is ejected from a vacuum hole opened on the upper surface of the table. At the same time, the suction is released and the work floats, and at the same time, the work is sucked through the vacuum hole of the suction work holder and the work is delivered to the work holder. Drilling. When the processing is completed, the moving means is controlled to the mounting section, and when the work is mounted on the mounting section, air is ejected from the vacuum hole opened in the suction work holder to release the suction and drop the work.
