Abstract

PURPOSE: To improve the control response performance by changing the signal valve by means of the carriage with cam and the operation transmitting rod.
CONSTITUTION: The cam 85 is mounted on the carriage 45, on which the cutting feature with a drill 43 is installed, to contact itself with the roller 55h of the operation transmitting rod 55g provided to the signal valve 55. By this way, when the carriage is moved to contact the cam with the roller and the operation transmitting rod is pushed to change the signal valve from the first position III to the second position IV, pressurized liquid discharged from the vane pump 2 flows in the rear cylinder 46b and liquid in the front cylinder 46a is returned to the tank 39 on restricting itself by the variable flow regulator valve 56. After the feed speed of the cutting feature is made constant according to the piston speed, the signal valve is changed to the third position V, the liquid in the front cylinder is returned to the tank through the variable flow regulator valves 56, 57, the feed speed of the cutting feature is reduced. Thus the control unit 93 and the actuator 46 are not required to communicate themselves with a long passage, the desired end can be attained.
