BNK30 SNEN1204ENS Solid CBN Inserts Fine Milling Engine Block Achieve Roughness RA1.6

BNK30 SNEN1204ENS Solid CBN Insert Fine Milling Engine Block achieve roughness Ra1.6

1. Halnn Tools BNK30 SNEN1204ENS CBN insertsFine Milling the engine block

Engine Block, as the base of the engine, it required high on the precision and surface quality, for example, side Flatness need within0.03mm, Cylinder roundness will be within0.004mm, and the Verticality will be within0.03mm, Surface Roughness require Ra1.6.

With the increasing competition on this industry, traditional cutting tools(carbide insert, ceramic cutters and coating carbide insert) can’t satisfy all the requirements . Many manufacturers can only use international brand (Seco, Sandvik, Sumitomo,ect) cbn insert, but it costs so high. So manufacturers are searching other cutting tools which can replace international cbn inserts, and reduce the tool costs.

2. Why we Choose Halnn Tools BNK30 SNEN1204ENS CBN inserts Fine Milling the engine block?

In order to meet the requirements of the automotive components industry, Halnn Tools, the predecessor of China superhard cutting tools, has researched so many cbn grades for machining engine, it not only can realize high speed cutting, improve the working efficiency, but also will guarantee high surface roughness and long tool life.

When milling engine End Surface, we usually use Halnn Superhard BN-S300, which belongs to solid cbn insert, it has excellent cutting tips, and the tip has high strength. In the process of milling engine with high cutting speed, it can obtain surface roughness Ra1.6.

For boring process, we recommend BNK30 and BN-K20 process, which is brazing pcbn insert. Comparing with common pcbn insert, it has more cutting edges, and perform stable. They have been widely used in engine industry.
