1 TOOLS NEWS Update B076G Solid CBN Grade for Cast Iron and Sintered Alloy Good balance of wear and fracture resistance from the high-performance sintering technology. New solid CBN for improved cast iron machining. High-speed machining at large depths of cut. Series Expansion

Solid CBN Grade for Cast Iron and Sintered Alloy 100% Solid CBN structure For highly efficient machining at large depths of cut Inserts made entirely of CBN do not limit the depth of cut.

$Application range for higher efficiency machining MB730 MB710 Balance of wear and fracture resistance The use of CBN particles and a newly developed special binder delivers high wear resistance.$

2 Solid CBN Grade for Cast Iron and Sintered Alloy 100% Solid CBN structure For highly efficient machining at large depths of cut Inserts made entirely of CBN do not limit the depth of cut. For the high speed and efficiency of CBN finishing but now also for roughing applications. Application range for higher efficiency machining MB730 MB710 Balance of wear and fracture resistance The use of CBN particles and a newly developed special binder delivers high wear resistance. Mitsubishi s unique high-performance sintering technology gives high fracture resistance.
