| Research Abstract |
For improving the performance of small-diameter cutting and grinding tools used for precision machining, a novel high-speed precision air-bearing tool spindle is proposed. The proposed tool spindle employs an active aerodynamic bearing for suppressing the spindle vibration occurring at high rotational speed. Owing to the active control, the amplitude of the spindle vibration can be suppressed to be 0.1μm at the maximum rotational speed of 44,000min^-1(730Hz) .
