  • Machine tool having a rotary table
    Patent number: 9533392
    Abstract: A machine tool includes a clamping mechanism for clamping/unclamping rotation of a rotary table. A load is measured when an unclamping command is output and then the rotary table is rotated after a set time set in the timer passes, and the set time of the timer is changed in response to a magnitude of the measured load. In this way, it is possible to prevent the clamping mechanism from being damaged due to a subsequent command given before unclamping ends, and extend a life span of a component.
