machiningpolycrystalline diamondCBN

SUMIBORON Binderless is a polycrystalline cubic boron nitrid (CBN) that directly binds nanometer- or sub-micron-level CBN particles without binder materials. Binderless CBN is harder and has better thermal conductivity. Therefore, it enables higher efficiency and longer tool life in machining of hard-to-cut materials, such as titanium alloy and cobalt-chromium alloy. Advantages of binderless CBN grades ■ Higher efficient machining and longer tool life have been realized by the effects of higher hardness and thermal conductivity ■ Achieves high precise machining and better surface integrity because of less adhesion by not containing any binder materials ■ High-efficient finishing of hard-to-cut materials, such as titanium alloy and cobalt-chromium alloy, cemented carbides and cermets ■ NBC100 is able to maintain excellent dimensional accuracy and surface roughness for a long period ■ Shows improved work efficiency and cost reduction by less frequency of exchanging inserts
