Moving Type Tail Stock |
摘要 |
A tail stock moving mechanism, in which a tail stock that holds a work with a predetermined pressure force is moved by a ball screw and in which control required for holding the work with the predetermined pressure force is implemented, is accomplished in a predetermined order wherein, the tall stock 1 holds a position of the work 5 and is supported by a ball screw 2, torque generated by a drive motor 3 that drives the ball screw 2 is detected, and when the torque reaches a predetermined reference value, then operation of a brake 4 to limit rotation of the ball screw 2 and cutting off of an input from a power supply to the drive motor 3 are performed. |
