SNFN120720 Solid CBN Cutting Insert Milling Cast iron Engine Block with better wear resistance
1. Halnn Tools BN-S300 Solid CBN Inserts Milling Cast iron 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 BN-S300 Solid CBN Inserts Milling Cast iron Engine Block ?
CBN Insert, the hardness is only second to diamond tools, has stable cuttingperformance, long tool life, and has been widely used. CBN Insert are mainly used for milling and boring engine block with gray cast iron materials. Specific for different process, we can choose different cbn grade, and can obtain best performance.
Specific for milling the endsurface and face of the engine, Halnn recommend BN-S300 solid cbn insert, it not only can be used for large margin in roughing process, but also can meet the roughness Ra1.6 in finishing process.
Specific for boring process of engine, Halnn recommend brazing PCBN insert BNK30 and BN-K20, BNK30 is one new materials for machining gray cast iron parts in high speed condition, the cutting speed can reach 200m/min, it has been widely used in engine processing.
