BNK30 CBN Inserts-the right choice for machining brake disc
With the rapid development of the auto parts, people recommend higher requirements on the auto parts. And brake disc, as one of the most important parts, it also required high on the product quality.
With the increasing competition of brake disc industry, more manufacturers begin to use CNC lathe to machine brake disc, and also it proposed high requirements on the corresponding cutting tools, it will need both the high efficiency and the long tool life. At this time, Halnn CBN inserts will be your right choice to machine the brake disc, and will ensure high quality surface and size accuracy.
As the predecessor of China Superhard Cutting Tools, Halnn offer the customers whole solutions together with the cutting tools. In 2007, Halnn already researched BN-S30 solid cbn insert for turning brake disc with high cutting speed, and make it possible to machine the gray cast iron parts with Chinese cbn insert.
Recently, Halnn also researched new cbn inserts BNK30, which can be used for high speed machining brake disc with cutting speed 500~2000m/min, which will satisfy the manufacturers because it ensure the stable performance, and has obvious advantages in finishing area. Compared with the carbide insert and coating insert, the tool life of the insert will be improved several times.
For example, BNK30 machining the brake disc
Workpiece Materials: FC250
Machining Process: Roughing
Workpiece Hardness:HB180~241
Roughness requirement: Ra1.6
Insert Model: BNK30 CNGN1204
Cutting Data: Vc=681m/min, Feed Rate: Fr=1.0mm/r, Cutting Depth ap=1mm
Machining Type: Dry Cutting
Processing Effect: Compared with similar product, with same cutting data, the tool life of BNK30 machining brake disc is about 1.45 times of previous cutting tools. The details as follows:
