Coated CBN Insert Performance Advantages
UHD Coated CBN Inserts combine a tough CBN substrate with multilayer PVD coatings, including TiAlN, TiN and TiCN, to provide improved wear resistance, heat resistance and cutting stability for hardened steel, cast iron and powder metallurgy machining.
The coating structure helps reduce cutting friction and suppress crater wear, oxidation wear and built-up edge formation, supporting stable surface quality and more predictable tool life in high-speed finishing, semi-finishing and selected interrupted cutting operations.
Coated CBN Insert Grades
Select the grade according to workpiece material, cutting speed, interruption level and required machining result.
