Abstract

PURPOSE: To increase the drill service life by controlling the drilling and feed speed in accordance with the drill thrust load of the drill.
CONSTITUTION: A thrust load detector 24 is installed inside a drill spindle 21 and is connected through the output of a feed speed position control circuit 37 and a thrust load operational calculus amplifier 45. By doing so, the drilling thrust load of a drill 23 detected by the thrust load detector 24 is imput through a strain amplifier 43 and a ropus filter 44 to the thrust load operational calculus amplifier 45 for effecting the designated operational calculus. After that, multiplying the output of the feed speed position control circuit 37, it is imput to a sirvo drive unit 38 comparing with a final drilling feed speed of a speed comparator 53. Then, a feed motor 12 is controlled and the feed speed of the drill is reduced according to the speed of drill blade wear-out
