Introduction

Fujio Aoshima is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of electrical discharge machining (EDM), holding a total of 2 patents. His innovative approaches have enhanced the efficiency and effectiveness of machining processes.

Latest Patents

Aoshima's latest patents include a device for electrical discharge machining of a work in the form of a roll. This device is designed to provide a satinized indented surface by satinizing operation to a predetermined surface roughness. It features two rows of heads, each mounting one or more electrodes, mounted on either side of the rotary axis of the roll. This design increases the number of heads and reduces working time. Additionally, one of the rows of heads is movably mounted on a shaft, allowing for transient displacement to an out-of-the-way position during roll handling operations.

Another significant patent is related to the EDM of a roll using segmented electrodes that are short-circuited during the rough machining step. This method involves applying an electrical voltage across the workpiece and electrodes, which are formed by multiple segments separated by insulators. The electrical discharge operation is performed with the segments short-circuited in the rough machining step and insulated in the finish machining step, effectively reducing working time.
