CONTROLLING METHOD FOR OPERATION OF SPINNING MACHINE

摘要

PURPOSE:To improve the working efficiency by determining a working cycle with a computer, inputting this into a storage medium, operating a controlling mechanism utilizing this storage medium and working a blank in accordance with set stage. CONSTITUTION:A blank W is lifted by an up-signal of a blank receiver 20 up to a prescribed position and the blank W is put by the advance of a tail stock 5 between the tail stock 5 and a mandrel 4. At the same time, a drawing tool is changed over to an operation circuit against a drawing roller 6 and a backup roller 16 is advanced to a position opposite to the drawing roller 6. The blank receiver 20 is lowered down to a relief position, the driving motor of a main spindle 3 is operated to rotate the main spindle 3 at a high speed, coolant is operated and a starting signal for the drawing operation by the drawing roller 6 is given. The controller 31 reads a drawing cycle stored in the storage medium IC inputted into an input part 32 and drawing operation is carried out based on this result. This drawing cycle is formed by a computer 2 and inputted in the storage medium IC.
