This paper introduces a novel tool clamping device based on the shape memory alloy in a micro-spindle system. Experiments, such as clamping/unclamping operation, repeatability of the clamping force, hysteresis characteristic, time drift of the clamping force, and comparison of the clamping forces according to basic designs were performed. These experimental results present the feasibility of the shape memory alloys for clamping tools in a micro-spindle.
