Abstract
An electrochemical discharge machining device includes a base, a sensor disposed on the base, a shaft rotatably disposed on the base, an electrode disposed at one end of the shaft and contacting with a work piece, an isolating element disposed between the sensor and the shaft, and a control module connected to the sensor. Current flows to the electrode via the shaft to machine the work piece, and the force exerted on the electrode by the work piece is transmitted via the shaft and the isolating element to the sensor converting the force into a signal sent to the control module for raising or lowering the base to maintain contact between the electrode and the work piece. The sensor serves as a detecting mechanism to ensure appropriate contact between the electrode and the work piece.
