PURPOSE:To effect all processing needle without reversing a work for improving processing efficiency by turning a copy device at an arbitrary position around an axis of the device directed perpendicularly to a flat plane of the device with respect to a reciprocating bench. CONSTITUTION:A cutter base 18 includes a cutter table 19 having cutting tools 19a, 19b and a copy device 21 having a styrus 20 mounted the eon. The base 18 being made free to turn is adapted to approach and slide in a direction of intersecting a central line of a main shaft. The cutter base 18 is inclined by 45 deg. to the side of a core press shaft 13, and intial copy processing for the work 12 is completed with use of a template 37 for an intial process. Then, the device 21 is forced to go back and to turn by 90 deg., and thereafter a remaining part to be cut in the intial process is cut by a template 38 for a reversing process, whereby all the process can be completed without reversal of the work. |
