BN-S300 CNC CBN Insert milling engine block with high efficiency from Halnn Superhard

With the development of the automotive industry, and the engine industry develop fast. And Engine Block as the most important component, most belong to mass production. Already 80% of the manufacturers use auto-line CNC Lathe finish all the process, and improve the efficieny obviously. However, it also needs suitable cutting tools. The cutting tools need to be used in high speed condition, and have long tool life. 

The materials of engine block are gray cast iron, and have low hardness. Traditional cutting tools can machine. But for the high requirements on the engine block, traditional cutting tools(carbide insert, ceramic cutters and coating carbide insert) can't satisfy all the requirements, many manufacturers use famous brand (Seco, Sandvik ) Insert for milling and boring prosess.

CBN Insert has high hardness, stable performance and long tool life, also can obtain good product quality, so it often is used for milling engine block with high cutting speed. Especially Halnn BN-S300, BNK30 and BN-K20 PCBN inserts, is the most widely used for milling and boring engine block.

And BN-S300 belong to solid cbn insert, mainly used for milling engine block, BN-K20 and BNK30 are brazing pcbn insert, are mainly used for boring process to make sure high surface quality and long tool life. And all of them have been widely used.

The application case of Halnn superhard cbn insert BN-S300 milling engine block

Machining Materials: Gray Cast Iron

Process: Finishing Process
