PURPOSE:To make it possible to automatically replace and feed various rod materials with different diameters in such a way that a material support in a main spindle which suits the diameter of the material and a material support in a stocker are unitized and variously prepared. CONSTITUTION:A guide tube 10 is integrated in such a way that stock tubes 12, 13 and silent springs 16, 17 are enclosed in a material stocker 11, according to the diameters of materials W. The material W has its front end part grasped by a grip part 14b of a material gripper 14, they are accommodated and held in the guide tube 10, and unified with the guide tube 10. The material W moves a block 13c of the stock tube 13 from the tube 10 to the side of a main spindle 4, along a hole 11a of the stocker 11 and is fed into the main spindle. |
