Fine CBN particles increase cutting edge toughness.
The high fracture resistance allows stable performance even during interrupted machining.
Optimization of the sintering conditions strengthens adhesion between fine CBN particles. This increases both fracture and wear resistance.
The SF type offers a sharper cutting edge, leading to the reduction in cutting resistance and burr development and an increase in surface finishes. The SF type is the first recommendation but to increase cutting edge strength and chipping resistance there are also the SE, FS, GS and TS edge preparations.
Increased fracture resistance even during heavy interrupted machining.
The above application examples are customer’s applications, so it can be different from the recommended conditions.
