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.
Dispersal of the newly developed Ultra Micro-particle Binder for sintered CBN and Micro Grain CBN suppresses cracking to prevent sudden fracturing.
*BC8110 is recommended to improve wear resistance.
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.
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.
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.
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.
