Latest Patents

Yasushi Goshima holds a patent for a cemented carbide end mill. This end mill features 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 a cross-section perpendicular to the end mill axis, it exhibits a smoothly concave shape that is radially inward. The core of the end mill has a diameter that is 62% to 68% of the outer diameter. The cutting edges are made from ultra-fine cemented carbide and are coated with a titanium-aluminum nitride hard film. This design enhances chip discharging during groove cutting and minimizes the inclination of cut grooves and corner wear of the end mill. He has 1 patent to his name.
