Finish Milling Gray cast iron Engine block with BN-S300 SNFN120716 CBN Cutting Tool achieve high linear speed
Halnn Tools BN-S300 SNFN120716 CBN Cutting Tool rough Milling the engine block
Halnn Tools PCBN tool processing boron cast iron, boron-copper alloy cast iron, wear-resistant alloy cast iron and other high wear-resistant cast iron cylinder liners, turning-grooving, rough machining, fine cylinder liner inner hole, semi-finished car, fine car The outer circle, the end face and the outer circle of the finished car have long tool life and high processing efficiency. The cutting performance of PCBN tools is much higher than that of coated carbide inserts, which can increase the life by nearly 5 times with greatly improved efficiency.
Why Choose Halnn Tools BN-S300 SNFN120716 CBN Cutting Tool rough Milling 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 within 0.004mm, 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 .
