Abstract

PURPOSE:To shorten the air-cut interval from the end of the quick-feed to the gnawing into the work rationally as much as possible, by constructing such that it is fed with the intermediate speed higher than the cutting feed speed until the cutting tool will enter into the cutting state. CONSTITUTION:The feed controller 3 for the cutting of such as a drill is equipped with a feed motor 4, encoder 4a, feed drive 10, feeding speed controller 11, magnification calculating command device 12 and a speed setting exchanger 13. The device 10 will provide the quick-feed speed, intermediate-feed speed, cutting-feed speed, final speed and the quick return speed while when the speed command of the comparison will change under the operational state of the intermediate feed speed, the motor 4 is exchanged to the cutting feed speed and from said speed to the final speed. Consequently the air-cut interval can be shortened.
