Abstract

PURPOSE: To perform efficient operation of turning machining the whole surface of a work, by inverting and reholding the work in a chuck after a completion of machining at an end part of the work and machining a root part of the work.
CONSTITUTION: After a work large contour part W' is turning machined, a front holding tool 32 of a holding device 27 holds said large contour part W' to open a chuck C. Then operation of an air cylinder 48 causes said front holding tool 32 to slide in the direction of an arrow mark B on a slide bar 28. Simultaneously with the above, a rear holding tool 33 is also slided in the direction of an arrow mark A by operation of an air cylinder 49 to exchange positions of the front and rear holding tools 32 and 33 and hold a work small contour part W" with the rear holding tool 33. Thereafter the rear holding tool 33 in the direction B and the front holding tool 32 in the direction A are shifted to again exchange their position. Then a rotary plate 26 is 180° rotated by operation of an air cylinder 22 to exchange the front holding tool 32 with the rear holding tool 33 and bite the work finished large contour part W' with the chuck C. In a state of this position the small contour part W" is turning machined.
