Abstract

PURPOSE:To prevent damage due to contact of the both with each other, etc. in such a way that when incipient tremor is detected during machining, power supply is interrupted, electric conduction is stopped, at the same time, a spindle is controlled so that the electrode can be separated from the work, and it is locked at the determined position. CONSTITUTION:Sensing signal 19 from a P wave sensor 18 which senses incipient tremor of the earthquake is given as input to a conditional circuit 20 to be connected to an operating circuit 15 and to a servo control circuit 14. Provided that P wave is sensed, a switch 22 on the switch circuit 21 is put to be in the condition as shown in the figure, and a power circuit 13 is turned OFF. Output is produced from the conditional circuit 20 by means of transfer of the switch 22 to the state as shown in the figure together with the sensing signal 19 from the P wave, and it is given as input to the servo circuit 14. The servo circuit 14 controls a servo 24 in the reverse direction extraneously to the fact that potential difference has turned out to be zero between signal lines 23a and 23b, and a spindle is sent up. And, it is brought to be stopped in the condition that it is sent up just for the determined distance.
