Latest Patents

One of Taguchi's latest patents is a method for electrical discharge machining of a work in roll form. This method provides a uniform satin finish to the roll surface in a short period of time. To prevent streaky patterns on the satin finish, a plurality of divided electrodes are arranged at predetermined spaces and fed traversely. This design allows for improved working efficiency, enabling the satinizing electrical discharge machining of multiple rolls to be completed within the lifespan of the rolls used in rolling mills.

Another significant patent is an apparatus for electrical discharge machining of cylindrical work. This invention focuses on producing a satin-like roughened surface of uniform roughness on the outer surface of satinizing rolls. The process involves decreasing the discharge current in proportion to the area being worked, ensuring a constant flow of current per unit area. The apparatus includes position detecting means to monitor the electrode's movement and control the off-time of the current pulse, enhancing the machining process.
