Milling Engine Block with gray cast iron materials use BN-S300 Solid CBN Insert from Halnn

Engine Block is one of the most important parts of engine, and is the base of the

engine. Engine Block is the typical case parts, and it usually uses milling process machining all surface. And the engine block usually require high on the product quality, and surface roughness, ect. So it requires high on the cutting tools, which will need high cutting speed, high precision and high efficiency.

In order to meet the requirements of the automotive components industry, Halnn superhard, 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.

 The application case of fine milling engine block surface with BN-S300 solid cbn insert

Compared with imported pcbn, the tool life of BN-S300 is longer , and the tool costs on each component lower obviously.

When milling engine block end surface, if the margin is large and the cutting speed is high, the cutting tools will be easily chipping or wear rapidly.
