Abstract

PROBLEM TO BE SOLVED: To provide a plate stock working machine reduced in installing space and installing cost, small in the error of working precision for a product capable of cutting off a nesting product. SOLUTION: One part of a work W is clamped with a first carriage 47 in the front side of a punch press 1, moved and positioned to/at the working position of the punch press 1, and punched. The remainder of the work W is clamped with a second carriage 51, moved and positioned to/at the working position, and punched. Since the second carriage 51 is used in common, the work W is moved and positioned as it is without being re-clamped to/and the shearing position an L shear 69 disposed at the front side in the conveying direction of the work with the second carriage 51. Since an L blade unit 67 is moved in the direction orthogonal to the conveying direction of the work and positioned at the shearing position, the work W is cut off in an optional position.
