Abstract

PURPOSE: To provide a tail stock to accurately and efficiently cut a slender, deflectable and heavy workpiece such as a crankshaft.
CONSTITUTION: A sleeve 3 is fitted in the body 1 of the tail stock of a lathe so that the sleeve can be moved in and out. The sleeve 3 is provided with feed means 15, 7 and a driver 19. The pitch of the feed screw 15 is selected on the basis of the lead of automatic locking. The lead angle θ of he screw and the angl θL of the automatic locking are related to each other as θ<θL or θ>θL. A thrusting force P1 is caused towards a rotary center 5 by energizing te driver 19. Another thrusting force P2 capable of causing reversal against the energizing of the driver 19 is applied from the side of the sleeve 3. Both the thrusting forces are related as P1<P2 on the basis of the angle θL. As a result, a workpiece is machined without being deflected.
