Finish Boring Cast Iron Cylinder head with BNK30 SNEN0904ENS CBN indexable Insert full form

1. Halnn Tools BNK30 SNEN0904ENS CBN indexable Insert Rough Machining the engine block

Engine Block, usually is made of gray cast iron, which has good strength, Stiffness

and wear resistance. And as the base of the engine, the engine block require high on the surface quality, for example, both side Flatness need within0.03mm, Cylinder roundness will be within0.004mm, and the Verticality will be within0.03mm, Surface Roughness require Ra1.6.

In order to satisfy all above requirements, the cutting tools need be used for high speed, and has high precision and high efficiency. It also can be used for milling engine block with large working allowance .

2. Why we Choose Halnn Tools BNK30 SNEN0904ENS CBN insertsCBN indexable Insert ?

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.
