Abstract

PURPOSE:To improve the positioning accuracy of the spindle by rotating-positioning the spindle at the point where the rotating energy of the spindle becomes low. CONSTITUTION:DC motor 5C of the spindle is decreased to be close to zero by the regeneration braking of the speed control amplifier 5B. The relay contact 8 is turned on after a period of time which is set in advance and where the rotation is almost zero to establish the position control system. The rotating angle theta of the spindle 2 is at the point P at the moment the relay 8 is turned on, and the angle theta is converted to the electric signal at the resolver 7A to turn the DC motor 5C so that the output voltage EP of the phase discriminator 7B is turned down to be the stable point S1 of the position control system. The motor 5C is stopped when the rotating angle theta reaches the point S1 as the stable point where it is position-controlled to complete the positioning of the spindle 2, and the tools can be smoothly exchanged.
