Halnn BN-S30 CBN inserts for turning Brake Discs with high efficiency
Brake Discs, as one of the main automotive parts, we usually use gray cast iron as
the main processing materials. With the mass production of brake discs and the
increasing costs on the raw materials, the manufacturers has much difficulties on
the profits. In order to make sure the profit ,they need to find the cutting tools
which can be used for turning brake discs with high speed turning .Cubic Boron
Nitride, as the cutting tools which can offer high efficiency , can improve the
processing craft and the processing efficiency.
In the past times ,the manufacturers use common lathe machine the brake discs. The
turning Craft is that roughing---semi-interrupted turning-finishing. It required
high on the precision and Parallelism of the brake disc . At beginning ,the
manufacturers use carbide insert turning brake discs .And it has good effect for
common lathe and small production .
With the development of the modern society, CNC Lathe will replace the common lathe
turning brake discs with high speed turning. When with high speed turning ,the
carbide cutting tools will be not wear. The cutting speed with carbide insert can
arrive 350m/min ,if the speed above it ,the carbide insert will be wear, so it will
change the insert frequently.
In current times ,Specific to brake discs manufacturers with mass production ,they
usually use cubic boron nitride cutting tools. Cubic Boron Nitride Cutting Tools are
the best cutting tools on processing the brake discs with high efficiency. The main
advantages are high efficiency, high quality and high precision .For example ,Halnn
BN-S30 and BN-K20 CBN insert ,which is researched non-metal adhesive solid cbn
cutting tools specific to brake discs
Halnn Superhard is a professional china cbn insert brand which include design
,produce and service. In 2007,Halnn already launched BN-S30 solid cbn insert
specific to high speed turning gray cast iron industry, which make cbn insert made
in china seen by the world.
The big difference between non-metal adhesive cbn insert and traditional cbn insert
is that improving the impact toughness with non-metal adhesive. Even though the
brake discs belong to Precision casting, it also will have some problems in the
casting process ,such as sand, which will lead to collapse or not-wear.Halnn BN-S30
don’t have these problems.
Application Case of Bn-S30 CBN insert roughing brake discs:
Machining Type: Roughing
Cutting Parameters: ap=2.5mm,Fr=0.45mm/r,Vc=350m/min
Processing Effect: Compared with coated insert, the productivity will be reduce
half .but the lifetime will be few times than coated insert.
If the precision required high ,Halnn will recommend you with BN-K20 welded pcbn
insert.Bn-K20 is researched for finishing process.
Cutting Parameters: ap=0.25mm，Fr=0.2mm/r，Vc=800m/min.
Processin , g Effect: Compared with coated insert ,when the cutting speed is 2.5~3
times of coated insert ,the insert lifetime will be about 20 times of coated insert
