Abstract

PURPOSE: To improve the control response performance by directly installing the driving motor and actuator on the casing that contains the oil pressure control circuit.
CONSTITUTION: The driving motor mounting face 1a, actuator mounting face 1b and operation transmitting rod projecting face 1c are provided to the casing 1, which contains the oil pressure control circuit 92, oil pressure pump 2 and signal valve 55, to install the motor 32 and actuator 46 directly and to make the operation transmitting rod 55g project. While the carriage of cutting feature is moved, the operation transmitting rod 55g is pushed by the cam 85, the signal valve 55 is operated, pressurized liquid discharged from the vane pump flows in the rear cylinder 46b, liquid in the front cylinder 46a is returned to the tank 39 through one or two variable flow regulator valves to control the speed of piston, that is, the speed of carriage 45. Since no long passage is present between the oil pressure control circuit 92 and the actuator 46, the desired end can be attained.
