Face Milling Gray Cast Iron Engine Block With BNK30 RNEN090400 CBN Turning Tools full form from Halnn
1. Halnn Tools BNK30 RNEN090400 CBN Cutting Tool full form face milling Cast iron Engine Block
For the automotives, engine is the most important component. With the Increasing competition, high speed milling the engine already become very important in this industry. And it is important for reducing the costs of each parts.
In modern times, most manufacturers use CNC lathe instead of common lathe, and the engine require high on the surface quality and the precision. So choose the right cutting tools become very important for milling, boring and turning process.
2. Why we Choose Halnn Tools BNK30 RNEN090400 CBN Cutting Tool full form face milling Cast iron Engine Block ?
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.
