Title:
CEMENTED CARBIDE CUTTING BLADE
Document Type and Number:
WIPO Patent Application WO/2021/256280
Kind Code:
A1
Abstract:
In the present invention, the ratio b/a is 0.30-1.00, where "a" represents a constant defined as a=Z1/(Y1)2 when an outer surface of a blade part is represented as YZ plane and a first point on the outer surface is assigned with the coordinates (Y1, Z1 (=1.00 μm)); b represents a constant defined as b=Z2/(Y2)2 when a second point on the outer surface is assigned with the coordinates (Y2, Z2 (=5.00 μm)). The blade part has a thickness T1 of 0.60-1.50 μm at Z1 in the Y-axis direction. When T1 falls between 0.60 μm and 0.91 μm, the relation 0.30≤b/a≤1.52T1-0.61 is satisfied. When T1 falls between 0.91 μm and 1.06 μm, the relation 0.64T1-0.28≤b/a≤1.52T-0.61 is satisfied. When T1 falls between 1.06 μm and 1.50 μm, the relation 0.64T1-0.28≤b/a≤1.00 is satisfied.
