Abstract

PURPOSE: To relieve indexing inertia of a spindle carrier, improve locating precision and thus to obtain product machining at high precision by arranging a bar material holder only on a spindle line corresponding to a bar material delivery position.
CONSTITUTION: A bar material kept on a feed holder 12 is delivered until 1 it comes to contact a stopper 15 and thus held on a holding unit 5; then after the feed holder 12 moves back, leaving delivery size and cutoff width of the bar material, a main spindle 6 rotates to the sized cutoff. Next, another main spindle 6 is brought to a bar material delivery position through indexing of a spindle carrier 4, thus the feed holder 12 operating for feed and cutoff.
