Milling Engine Block with gray cast iron materials use BN-S300 Solid CBN Insert from Halnn

Engine Block is one of the most important parts of engine, and is the base of the engine. Engine Block is the typical case parts, and it usually uses milling process machining all surface. And the engine block usually require high on the product quality, and surface roughness, ect. So it requires high on the cutting tools, which will need high cutting speed, high precision and high efficiency.

Specific for milling and boring engine block with cast iron materials, Halnn launched many cbn grades, not only can realize high speed milling process, but also can reduce the tool costs.

(1)  Milling Process: Halnn recommend Solid CBN Insert BN-S300, obvious process efficiency, stable cutting performance, can replace Seco and other brand CBN.

(2)  Boring Process: We recommend BN-S300,BNK30 and BN-K20 Brazed PCBN Insert, it has stable performance and has been widely used in Engine Industry.

(3)  Chamfering process: It can be made depending on the customers' requirements, the cutting performance will be stable .

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

Machining Materials: Gray Cast Iron

Process: Finishing Process
