Successful cases of CBN tools in Halnn (Coating CBN inserts for machining gears) Cutting tools is a key role in the machining. As machining technology continues to improve, high precision and long life are increasingly sought after attributes by factory. In order to meet the ever-leaning and diversified needs, Halnn continues to innovate and enrich our product line, which provides strong support to help you achieve high efficiency and high precision machining. At present, Halnn BN-H05, BN-H10 and BN-H21 are the three common grades of coated PCBN inserts on the market. At the same time, Halnn has also upgraded the number of cutting edges, which doubles the number of cutting edges, and coupled with the exquisite coating technology, the life of the tool has been significantly improved.
