Abstract
Disclosed herein is a method for processing an orifice capable of processing recessed portions and orifices, each having a unique hole diameter different from each other, to high positioning accuracy and in a short time. A press includes: a B-axis angle indexing devicedisposed on a base, the B-axis angle indexing deviceincluding a table B; an A-axis angle indexing devicedisposed on the table B, the A-axis angle indexing deviceincluding a table A; a chuckdisposed on the table A, the chuckfor holding a work; a base Zdisposed on a base, the base Zbeing operable in an axis Z-direction; a base Xdisposed on the base Z, the base Xbeing operable in an axis X-direction; a punch holding portiondisposed on the base X, the punch holding portionbeing operable vertically in an axis Y-direction; and a plurality of punchesheld on the punch holding portion in parallel with the axis Z. The press is used to perform a pressing cycle at a desired position by changing a posture of the work and moving the punch in the Z-direction continuously using punches having different leading end diameters and shapes with the work held in the chuck.
