摘要： There is disclosed a device for electrical discharge machining of a work in the form of a roll for providing a satinized indented surface by satinizing operation to a predetermined surface roughness, wherein two rows of heads each mounting one or more electrodes are mounted on either sides of the rotary axis of the roll for increasing the number of heads and thereby reducing the working time. One of the rows of heads is movably mounted on a shaft on the side of roll handling operation of the roll for transiently displacing the heads in their entirety to an out-of-the-way position for solving the problem caused by roll handling and by the increase in the number of heads.
