Title: Takao Nakamigawa: Innovator in Cutting Tool Technology
Introduction
Takao Nakamigawa is a distinguished inventor based in Narita, Japan. He has made significant contributions to the field of cutting tool technology, holding a total of three patents. His innovative designs have advanced the efficiency and effectiveness of cutting tools used in various industrial applications.
Latest Patents
Nakamigawa's latest patents include a cutting insert and a cutting edge-interchangeable rotary cutting tool. The cutting insert features arcuate cutting edges that protrude toward the outer circumference of the distal end. A chisel part is formed at the intersecting ridge line between the flank faces of the pair of arcuate cutting edges. Additionally, a round honing is created on the cutting edge tip of the arcuate cutting edge, particularly where the radial angle is 30 degrees or less. The curvature radius of the round honing in a cross-section perpendicular to the edge length direction of the arcuate cutting edge ranges from 20 to 40 micrometers. Furthermore, the chisel angle formed between the distal end part of the arcuate cutting edge and the chisel edge of the chisel part is between 150 degrees to 170 degrees when viewed from the insert front.
Another notable patent is for an indexable rotary cutting tool and insert. In this invention, the cutting edge portion of the insert includes a peripheral cutting edge, a bottom cutting edge, a cutting edge of a corner R, and a chamfered surface. The radial rake angle of the cutting edge of the corner R has a negative value across the entire edge length region, reaching a minimum value at an intermediate portion located between two boundary points in the cutting edge of the corner R.
