Rough Machining Cast Iron Cylinder block with BNK30 RNEN120700ENS full form CBN Turning Insert
1. Halnn Tools BNK30 RNEN120700ENS full form CBN inserts face milling Cast iron Engine Block
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.
2. Why we Choose Halnn Tools BNK30 RNEN120700ENS full form CBN inserts 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.
