ABSTRACT:
A wire electric discharge machine having a simple mechanism for retracting and collecting a cutoff piece (machined chip or machined product). A cutoff piece receiving basket for receiving a cutoff piece produced during machining is attached to a support bar mounted to a lower guide block, the basket being rotatably supported by a rotary support shaft. A bearing provided in the support bar is located immediately short of a cam block, and then fitted into a slot by X-axis movement. A moment is applied to the support bar by Y-axis movement to rotate the cutoff piece receiving basket around the rotary support shaft, so that the basket is retreated to above a cutoff piece collecting box and then turned over, whereby a cutoff piece received in the basket falls into the collecting box. The cutoff piece receiving basket may be rotated manually or rotated by use of a robot, a special-purpose motor, an air cylinder, etc.
