Title: The Innovations of Susumu Sawafuji
Introduction
Susumu Sawafuji is a notable inventor based in Mitaka, Japan. He has made significant contributions to the field of measurement and slicing technology. With a total of 5 patents to his name, his work continues to influence various industries.
Latest Patents
One of his latest patents is a hole shape measuring method and apparatus. In this innovative measuring apparatus, an arm is lowered to insert a measuring sphere into a hole in a workpiece. The measuring sphere is then lowered in the depth direction of the hole. This design allows for the detection of back pressure from compressed air at multiple locations using an air/electricity converter. The detected values are compared with a master reference value by a controller, which converts the detected value into the inside diameter of the hole. This method enables the accurate measurement of various hole shapes.
Another significant invention is a slicing machine with a built-in grinder. In this design, the rotational center of the grinding wheel is eccentric to the slicing side in the slice feed direction, relative to the rotational center of an inner diameter saw. This configuration allows for a smaller diameter of the grinding wheel and a shorter slice movement distance of the ingot. Consequently, this innovation provides a cost-effective slicing machine with a built-in grinder, where the slicing time is reduced, and the grinding face remains accurate.
