Title: Hiromichi Shichida: Innovator in Wire-Cutting Technology

Introduction

Hiromichi Shichida is a notable inventor based in Hino, Japan. He has made significant contributions to the field of machine tools, particularly in the development of advanced wire-cutting electric discharge machines. With a total of 3 patents to his name, Shichida's work exemplifies innovation and precision in manufacturing technology.

Latest Patents

One of Shichida's latest patents is a numerically controlled wire-cutting electric discharge machine. This machine features a numerical control apparatus that manages the feeding of a workpiece across at least three axes. The wire-cutting discharge apparatus includes a pair of V-type slot guides that stretch a wire between them. It also incorporates a first and second drive means that displace the work in two axes relative to the wire electrode, along with a third drive means that rotates one of the V-type slot guides around a predetermined axis. This design allows for precise control of the relative displacement between the workpiece and the wire electrode.

Another significant patent is a tool-indexing apparatus for machine tools. This apparatus consists of a member that moves in a linear direction, a set of ball screws connecting the member to a tool-post, and a stopper that restricts the linear movement of the tool-post. Two coil springs resist the linear movement of both the tool-post and the member. During operation, the member and tool-post are lifted, and once the tool-post abuts against the stopper, it is revolved using the ball screws and one of the coil springs, facilitating the tool-indexing operation.
