Title: The Innovative Contributions of Toru Sekiguchi
Introduction
Toru Sekiguchi is a notable inventor based in Toyama, Japan. He has made significant contributions to the field of drilling and milling technology, holding a total of three patents. His work focuses on enhancing the efficiency and effectiveness of cutting tools used in various industrial applications.
Latest Patents
One of Sekiguchi's latest patents is a drill designed with multiple flanks. This innovative drill is capable of suppressing inter-layer peeling (delamination) while maintaining hole diameter accuracy, even when the number of holes to be worked increases. The drill features a first flank with a ridge line forming a cutting edge, a second flank adjacent to the first with a ridge line forming a land portion, and a third flank with a ridge line forming a chisel edge. Additionally, it includes a fourth flank surrounded by ridge lines forming the first and third flanks, along with a trough line forming the second flank.
Another significant patent is for a cemented carbide end mill. This end mill is characterized by having three or more cutting edges formed on its periphery, with flutes provided between adjacent cutting edges. The land width of each cutting edge and the flute width maintains a ratio of 1:1.5 to 1:4. Each flute has a helix angle ranging from 35° to 60°, and when viewed in cross-section, it has a smoothly concave shape radially inward. The core of the end mill has a diameter that is 62% to 68% of the outer diameter, and the cutting edges are made from ultra-fine cemented carbide, coated with a titanium-aluminum nitride hard film. This design enhances chip discharging during groove cutting and reduces corner wear.
