PURPOSE:To facilitate memory operation of the device by moving a tracer provided with a position detector along a mandrel, storing the locus of moving, and performing drawing work NC controlling forward and backward movement of a drawing roller based on the memory. CONSTITUTION:A tool rest 2 to which the drawing roller 1 is mounted is placed on a reciprocating stand 3 on a fitting stand 4 to allow movement in the direction of X, Z axes by hydraulic cylinders 5, 6. A copying touch piece 12 of the tracer 10 provided on the stand 2 is positioned on the mandrel 8 through a position detector 10, a position controlling mechanism 13 and a driving mechanism 14. Then, the tracer 10 is moved along the mandrel 8 and the locus of shifting is stored. A work on the mandrel 8 is drawn NC controlling and driving forward and backward movement of the roller 1 based on the memory. Thus, the labor for mounting and setting of a copying template etc. is eliminated, and the good memory reproduction is obtained by simple memory operation. |
