Abstract
A water drive spindle has been developed for applying it to diamond turning machine. The water drive spindle is tested for diamond turning in the present paper. A linear stage system is designed and its performance is evaluated, prior to the diamond turning experiments. Optical quality surfaces were obtained in the diamond turning using the water drive spindle and the linear stage system. The surface roughness of the workpiece was typically R_a 0.03μm. Influence of the pressure pulsation of the water flow on the machined surfaces was experimentally studied. Rotor vibration due to the pressure pulsation was observed in the experiments.
