BN-S300 Solid CBN Insert Fine Milling Engine Block achieve high linear speed 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. 

In order to meet the requirements of the automotive components industry, Halnn superhard, the predecessor of China superhard cutting tools, has researched so many cbn grades for machining engine, it not only can realize high speed cutting, improve the working efficiency, but also will guarantee high surface roughness and long tool life.

When milling engine End Surface, we usually use Halnn Superhard BN-S300, which belongs to solid cbn insert, it has excellent cutting tips, and the tip has high strength. In the process of milling engine with high cutting speed, it can obtain surface roughness Ra1.6.

For boring process, we recommend BNK30 and BN-K20 process, which is brazing pcbn insert. Comparing with common pcbn insert, it has more cutting edges, and perform stable. They have been widely used in engine industry.

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

Machining Materials: Gray Cast Iron

Process: Finishing Process

Insert Model: BN-S300 SNEN090308ENS

Cutting Data: Vc=1700m/min, Fz=0.12mm/r,ap=0.3mm

Machining Process: Dry Cutting

The performance:

When milling engine block end surface, if the margin is large and the cutting speed is high, the cutting tools will be easily chipping or wear rapidly. You can contact with us, We can offer you professional service. Online contact way as follows: skype:cbn_inserts_angels, Wechat:Halnntools
