Although he currently holds no granted patents, his work in developing advanced cutting inserts showcases his expertise and creativity.
Latest Patent Applications
Hiroaki Hayashizaki's latest patent applications include two notable inventions. The first is a drill insert designed to ensure sufficient chipping resistance under large cutting loads. This drill insert is detachably attached to the distal portion of a drill body, which rotates around an axis. The insert features a polygon face that serves as a rake face, with a cutting blade formed at the intersection of the rake and flank faces. The cutting blade includes a honing face with two convex curved faces, each having different curvature radii.
The second application is for a cutting insert formed in the shape of a tetragonal plate. This insert has a pair of tetragonal faces and four side faces, with four cutting edges formed at the ridge lines between adjacent side faces. Each cutting edge consists of a major cutting edge and two minor cutting edges extending from its ends. The design includes tetragonal rake faces that enhance cutting efficiency, with major cutting edges extending in different directions to intersect in an X-letter shape.
