COATED CBN

BC8100 series for machining of hardened steel

FEATURES

The coated CBN grade BC8100 series and non-coated CBN grade MB8100 series for cutting of hardened steel uses new developed optimized substrate technology CBN base material. The new ultra-micro-binder prevents sudden fracturing and longer tool life. The BC8100 series coating exhibit excellent fracture resistance and wear resistance by using a special PVD coating suitable for each cutting mode.

Newly Developed Special PVD Coating

The newly developed Ultra Micro-particle Binder prevents sudden fracture

Dispersal of the newly developed Ultra Micro-particle Binder for sintered CBN and Micro Grain CBN suppresses cracking to prevent sudden fracturing.

Application range

*BC8110 is recommended to improve wear resistance.

Recommended cutting conditions

Cutting example and application example

BC8105 Highest Accuracy

Use of a CBN substrate with excellent wear resistance and chipping resistance, together with a high-lubricity coating film,controls the occurrence of boundary wear and exhibits outstanding surface roughness.

Suitable for finishing with surface roughness Ra 0.6 μm or Rz 2.4 μm or less.

BC8110 High Speed Turning

Use of a CBN substrate with excellent wear resistance and chipping resistance, together with an extremely hard coating
film, provides the highest flank wear resistance of the entire BC8100 series.

BC8120 General Application

Use of a CBN substrate with excellent fracture resistance and crater wear resistance, together with a coating film having superior wear resistance, combines both fracture resistance and wear resistance while exhibiting outstanding crater wear resistance.

BC8130 Tough Machining

Use of a CBN substrate with excellent cutting edge strength, together with a coating film that combines hardness with impact resistance, allows it to exhibit outstanding cutting edge strength and fracture resistance.
