Introduction of long carbide blades
Takuhiro NAKAGAWA, Ryuichi SAKAMOTO
Key words long carbide blade, cemented carbide, diffusion bonding

Abstract

Cemented carbide is known as having high melting point and extremely hard material. However, manufacturing a long tool was limited due to such characters. Then, we established the manufacturing technology of long carbide tools by using diffusion bonding, and produce them on a commercial basis. The long carbide products are applied to blades etc, showing excellent durability (abrasion resistance) compared with steel blades with high quality.
