Abstract

PURPOSE: To make it possible to set the degree of acceleration and deceleration of a spindle simply and freely and thus enable tapping with high precision by making the normal and reverse rotation of a tap spindle by means of the cam groove of a cylindrical cam.
CONSTITUTION: A case frame 12 is rotated by a motor 25 started and a ball screw nut 15 equipped with a follower 16 fitted in the cam groove 4 of a cylindrical cam 6 is moved up and down on a ball screw lever 14 by the action of the cam groove 4, not being rotated on its own axis. Accordingly, the ball screw lever 14 rotates lightly in both normal and reverse directions in accordance with the moving speed of the nut 15. Simultaneously, a tap spindle 18 is rotated and, by the screwing of the lead male screw part of the spindle 18 with the lead female screw part 23 of a multispindle tap shaft 19, the tap at the tip of the spindle 18 lowers or rises, making a right screwing movement in accordance with the screw thereof, thus the tapping of a work to be worked on a working table provided in a tubelike boss part 8 is conducted by a tap 28.
