For the automotives, engine is the most important component. With the Increasing competition, high speed milling the engine already become very important in this industry. And it is important for reducing the costs of each parts.
In modern times, most manufacturers use CNC lathe instead of common lathe, and the engine require high on the surface quality and the precision. So choose the right cutting tools become very important for milling, boring and turning process.
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 .
