Title:
WOOD-CUTTING CUTTER AND METHOD FOR REGRINDING SAME
Document Type and Number:
WIPO Patent Application WO/2023/234389
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a wood-cutting cutter which is used for the cutting processing of a woody material and that can be easily reground. The wood-cutting cutter has a hardened layer provided on a surface of a cutting blade thereof, the hardened layer comprising a base material that has been modified by nitriding or carburizing. The surface hardness of a blade portion is more than 40 HRC. The wood-cutting cutter is formed of tool steel. The hardened layer formed on the surface by nitriding or carburizing is integrally formed with the base material, and is therefore less likely to experience damages that occur independently due to regrinding, such as delamination, unlike in the case of a coating layer.
