Introduction
Daisuke Yoshiba is a prominent inventor based in Iwaki, Japan. He has made significant contributions to the field of cutting tool technology, holding a total of 2 patents. His innovative designs have enhanced the efficiency and accuracy of threading processes in manufacturing.
Latest Patents
Yoshiba's latest patents include a cutting insert for threading and a tool body and cutting tool. The cutting insert for threading features two opposing end surfaces and a peripheral side surface that extends between them. This design includes a first side surface portion and a second side surface portion arranged at different positions in a circumferential direction. A cutting edge is formed at the intersecting ridgeline portion between the first end surface and the first side surface portion, with a shape that corresponds to a thread groove. The second side surface portion has an inclined portion that enlarges outward, preventing the cutting insert from floating when engaged with a tool body.
The threading cutting insert achieves high shape accuracy for screws being processed while also reducing manufacturing costs. It features a plurality of tooth-shaped cutting edges formed in a cross ridge line portion between a rake face and flanks on the cutting side face. This design provides at least one finishing cutting edge for transferring the shape of a screw and at least one roughing cutting edge that is smaller than the finishing cutting edge. The finishing cutting edge includes a first flank and a second flank with a larger clearance angle, arranged sequentially from the rake surface toward the lower surface of the insert.
