Japanese Patent JPS5912414

Kind Code:

B2

Abstract:

There is disclosed a method for giving by electrical discharge machining a uniform satin finish to the roll surface of a work in roll form in a short period of time. To prevent the occurrence of any streaky pattern on the satin finish work surface, a plurality of divided electrodes, which are divided and arranged at predetermined spaces, are each fed traversely a distance corresponding to the electrode mounting pitch while maintaining the predetermined spacing between the electrodes. To improve the working efficiency, a plurality of rows of divided electrodes are provided, and by virtue of this improved working efficiency, the required satinizing electrical discharge machining of two or four rolls for use on a rolling mill can be completed within the life time of the satinized rolls being used on the rolling mill.
