Abstract
PURPOSE: To eliminate exothermic effect upon stopping of a main spindle and an idle time therefor by a method wherein the stock held by a material sending chuck of a material feeder main body is rotated in synchronism with the rotation of the main spindle and the main spindle is not stopped even when the stock is being fed.
CONSTITUTION: The bar having polygonal or deformed section is carried onto a bar supplying track beforehand manually or automatically. The outer periphery of the bar is coincided with phases of the material feeding chuck 26 of the bar feeder, arranged at the back side of the machine tool, and the same of holding sections 31a, 6a of a main spindle chuck 6 of the main spindle 4. The material feeding chuck 26 of the material feeder 18 is rotated in synchronism with the main spindle 4 while the main spindle 4 is being rotated and the main spindle is not stopped in an automatic feeding operation of the continuous bar, further, the main spindle 4 and the chuck 26 are rotated in synchronizing and one cycle is completed after the bar has been consumed already.
