BNK30 RNEN Solid CBN Insert rough milling engine block with high precision

Halnn Tools BNK30 RNEN CBN inserts rough Milling the engine block

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.

Why Choose Halnn Tools BNK30 RNEN CBN inserts rough Milling the engine block ?

The advantages of Halnn CBN Inserts machining gray cast iron part.

(1) Improve Efficiency: Compared with coating carbide insert, it can realize high speed machining,and the suitable linear speed will be: 250~450m/min for roughing process, 450~800m/min for finishing process.

(2) Improve Tools Durability: The tool life of Halnn CBN Insert is about 15 times of carbide insert.
(3) Improve Roughness: Halnn BN-K20 and BN-S30can receive the roughness within Ra1.6, is much better than carbide insert.

(4) Characteristics of Halnn CBN inserts: BN-S30 and BN-S300 adopt non-metal adhesive, improved the thermal conductivity and the strength, not only extend the insert lifetime, but also improve the impact resistance. And BN-S30 can be used for roughing process, BN-S300 can be used for finishing process. BN-K20 and BNK30 belong to brazed pcbn insert, both of them can be used for finishing process.
