Cutting edge design for CBN cutting materials

The ATORN cutting edge range includes various
distinct cutting edge designs. The standard range in- A
cludes different chamfers on the cutting edge. These
include sharp-edge (A) to high chamfer versions B
(G), depending on the application. The use of high C
chamfers on the cutting edge can achieve very good
surfaces, but the forces are increased. Sharp-edge D Cutting forces Cutting edge stability
variants are the appropriate choice for long projec- <Rz
tions with unstable conditions. E
