NCB100 Binderless CBN

Precision and Longevity Through Innovative Technology
NCB100 binderless CBN grade stands out for its exceptional tool life and precision. Thanks to its higher hardness and improved thermal conductivity compared to conventional CBN grades, NCB100 enables more efficient machining and significantly longer tool life. These properties make it particularly well-suited for machining hard-to-cut materials such as titanium alloys and cobalt-chromium alloys.

The increased hardness of NCB100 significantly enhances the wear resistance of the tool. At the same time, the improved thermal conductivity ensures efficient heat dissipation during the machining process, which reduces thermal stress and thus also contributes to extending tool life.

Another advantage of NCB100 is the absence of a binder material, which results in a lower affinity for the materials being machined. This enables very precise machining and better surface quality over a long period. NCB100 is capable of ensuring excellent dimensional accuracy and surface finish over an extended period, which minimizes the need for frequent tool changes.

The combination of these properties results in improved productivity and cost savings due to less frequent insert changes compared to conventional tools. This makes NCB100 an ideal choice for applications that require long tool life with high precision, especially when machining demanding materials in the aerospace, nuclear, and medical industries.
