Abstract

PURPOSE:To make a disk safely machinable from an angulate plate material by installing a work cutting part eliminating the corner part of a workpiece and a work turning part turning a end face of this workpiece. CONSTITUTION:A cutting motor 67 is driven, and a second carriage is traveled to the left by a reciprocating means in a state of rotating a round tool 65. With this operation, a corner part of a workpiece is cut off. Next, a work turning part is started, making a tool rest 72 go up by means of rotation of the cutting motor, and an end face of the workpiece is turned by cutting tools 72a of the tool rest 72. At this time, since a lower side one of these two cutting tools 72a is made so as to be more plenty in an infeed rate than the upper side one in terms of design, this turning operation is finished with one process alone. With this constitution, a square plate is machined into a disk.
