Title: Yasuo Hamatake: Innovator in Cutting Tool Technology
Introduction
Yasuo Hamatake is a notable inventor based in Toyokawa, Japan. He has made significant contributions to the field of cutting tools, holding a total of five patents. His innovative designs focus on enhancing the efficiency and effectiveness of cutting processes.
Latest Patents
Hamatake's latest patents include advancements in throwaway rotary cutting tools. In his semi-finishing cutter design, rectangular tips and square tips are arranged in a staggered pattern along the axial direction in the second to fourth step portions. This configuration allows for a single cutting edge to be formed by pairing one rectangular tip with one square tip. As a result, the frequency of contact with the blade root is effectively reduced. This design enables an increase in cutting speed and faster cutting feed, making the semi-finishing process more efficient. The simplicity of the rectangular and square tips allows for the use of commercially available throwaway tips, providing an easy-to-use semi-finishing cutter without raising costs. Additionally, in his rough cutting cutter, square tips and rectangular tips are also arranged in a staggered pattern. The design features rake angles that gradually increase from the tip end to the back end of the tool body, which helps suppress chatter vibration during machining and reduces the roughness of the cut surface.
