The Development Trend of Cutting Tools
Cutting tools have been improved to endure severe environments in cutting operations. Especially, ceramic film coating technologies are important. Recently, film structure is optimized and tensile stress in film is controlled, as a result new tools which have the newest coating achieved double the tool life and 1.5 times higher efficiency compared with conventional tools. In tool design, progressive molding and sintering techniques allow more complicated tool shapes which have high rake angles to reduce cutting force, higher accuracy equivalent to grinding class tools and more excellent performance.
