In order to realize a feed rate of 20 m/min for cutting operation of mediurn-and large-size machine tools, a new high-speed and high-accuracy feed drive system which has a servo-motor and ball screw combined with a hydraulic actuator has been developed. The previous papers clarified that this system is able to drive a table, weighing about 1 ton, ten times a fast as the conventional rate with considerable accuracy. This paper deals with the improvement of the hydraulic system which has an unfavorable time delay. The experimental results show that the time delay of the hydraulic system was reduced to one-sixth of the previous amount, and accuracy of circular interpolation for a 150 mm radius was improved to 149 μm at a feed rate of 20 m/min. This amount is smaller than for the previous system by about 100 μm
