This study deals with the feasibility of electrical discharge machining by means of a size-reduced in-pipe movable mechanism which will be employed to fabricate long and thin curved holes. To establish a curved hole machining method, the devices have been developed, which can machine curved holes. However, they cannot fabricate long curved holes. Thus, the authors planned to realize the long curved hole machining method which employs an inpipe movable mechanism. Actually, the in-pipe movable device to machine a long curved hole has been developed. However, the diameter of its machining hole is too large. To solve the problem, it is required to reduce the size of the in-pipe movable device since the diameter of the machined holes depends on the size of the device. In the study, therefore, the size-reduced in-pipe movable device is developed. From the result of the basic machining experiment, it is found that the device can perform a stable electrical discharge machining and make a hole.
