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”


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.

High toughness of cutting edge

Results

Increased effi ciency with BC8110 due to fewer tool changes required.

BC8110 achieved 2.5 times longer tool life and could continue machining.

Longer tool life meant reduced insert indexing.
