Introduction

Yutaka Hayashi is a notable inventor based in Chiryu, Japan. He has made significant contributions to the field of grinding technology, holding a total of 4 patents. His innovative designs have enhanced the efficiency and accuracy of machining processes.

Latest Patents

One of Hayashi's latest patents is a grinding wheel with at least two wheel cores for circumferential grinding. This grinding wheel is designed for use in a grinding machine and is attached to a wheel spindle for simultaneously grinding at least two parts of a workpiece. The grinding wheel includes at least two disk-like wheel cores, each with an abrasive layer on its circumferential surface. A spacer portion is inseparably fixed on at least one of the wheel cores to maintain a space between the abrasive layers. Additionally, a first labyrinth portion is located on one of the side surfaces of one of the wheel cores to form a labyrinth seal with a second labyrinth portion arranged on the grinding machine. This design significantly reduces the number of separable parts, enhancing balance and stability during high-speed operations, which ultimately improves machining accuracy.

Another patent focuses on a method for machining a workpiece by renewing a tool's movable range. This machining apparatus allows for the movement of a tool in relation to the workpiece, with a tool movable range setting means that inhibits the workpiece from exceeding a reference size. The apparatus halts the tool's movement if it exceeds the set movable range, ensuring precision in machining operations.
