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.
