Cutting Edge Treatment Speci cation Optimal cutting edge treatment applied to various grades and geometries to avoid cutting edge fracture caused by the heavy loads generated during the machining of high-hardness materials such as hardened steel.
High-precision type World's smallest class edge treatment for coated CBN in hardened steel machining. Lowers cutting force. Strong Edged Suppresses cutting edge chipping and fracture. Stable tool life in interrupted machining. HS High-eciency type Suppresses crater wear and its resultant edge chipping. Stable tool life in high-speed, high-feed machining. ES LE LT LS
