Title: Hiroyasu Shimizu: Innovator in Superabrasive Technology

Introduction

Hiroyasu Shimizu is a notable inventor based in Okazaki, Japan. He has made significant contributions to the field of superabrasive technology, holding 2 patents that showcase his innovative approach to manufacturing processes.

Latest Patents

Shimizu's latest patents include a "Superabrasive Grain Setting Apparatus" and a "Superabrasive Grain Setting Method." The superabrasive grain setting apparatus is designed to arrange superabrasive grains on the surface of a manufacturing mold used in grinding tool production. This apparatus features a grip and raising mechanism that allows the mold to be turned from a horizontal to a vertical state. It incorporates a six-axis control robot, which consists of a base arm mechanism with three controlled axes and a wrist unit with three controlled axes. Additionally, the apparatus includes a superabrasive grain supply device that stores the grains and separates them one by one for suction. The suction nozzle is equipped with a bent nose portion to facilitate the drawing of superabrasive grains.

The superabrasive grain setting method involves a two-dimensional coordinate preparation step, where a non-cylindrical area of the mounting surface is developed into a circular-arc belt-like surface. A grid pattern of mounting points is established on this surface, ensuring that the points do not create consecutive lines in the circumferential direction. This method enhances the precision of mounting superabrasive grains on the manufacturing mold.
