Cutting resistanceForces dispersed in a linear direction can cause sudden fracturing.
Forces dispersed radially help to prevent sudden fracturing.
Cutting resistance
Conventional
Dispersal of the new Ultra Micro-particle Binder in BC8110 prevents linear crack development that can cause sudden fracturing.
The newly developed “Ultra Micro-particle Binder” prevents sudden fracturing

“Ultra Micro-particle Binder”
Coated CBN Grades for High Hardened Steel Turning
Newly developed special ceramic coating
Chipping caused by built up edge is prevented with improved welding resistance.
Prevention of welding
CBN sintered body“Ultra Micro-particle Binder”
Improved wear and chipping resistance.
Improved adhesion of the coating to the CBN surface increases peeling resistance.
TiAlSiN Coating
TiAlN Coating
Chipping caused by built up edge is prevented with improved welding resistance.Improved adhesion of the coating to the CBN surface increases peeling resistance.
Excellent stabilityTiAlN-base coating
Ultra Microparticle Binder controls cracks.New particle-activated sintering method is employed.
