Halnn Superhard CBN cutting tools processing auto cast iron parts solutions

Auto parts are made from gray cast iron with a variety of shapes, the choice of cutting tools to be considered the tool and the work piece gap, must not have any interference.

Halnn Superhard provide professional and efficient cbn cutting tool according to process various structural automotive cast iron parts. Select different cutting tools model number according to different parts, not only increase productivity, but also reduce processing costs.

1.Auto parts brake disc processing

① Roughing: Select Halnn superhard developed non-metallic adhesive CBN insert BN-S30 grades, is also suitable for the finishing procedure, when roughing brakes disk, often using rhombus inserts and square inserts. High processing efficiency, and can well controll precision demand. such as CNMN120416, CNMN120718; SNGN120412; SCGN0904 brakes are usually used to roughing brakes disc inserts model number.

Halnn Superhard non-metallic binder CBN inserts BN-S30 grades features:

1).High hardness, good wear resistance;

2).Non-metallic (ceramic) as a binder, a strong impact toughness;

3).Good stability and good reliability;

4).It can meet all kinds of machine tools cutting processing;

5).High-speed cutting efficiency high;

6).Dry Cutting reduce environmental pollution;

②Fine finishing: Halnn Superhard cubic boron nitride inserts BN-K20 grades belong welded CBN inserts, only suitable for a small margin for fine finishing procedure. Inserts have many models, such as the triangle, rhombus, etc., VNGA120408; WNGA080408; TNGA160408. Fine finishing cutting speed can reach up to 1500m / min. The cutting tool can withstand high-speed cutting in the case of machine tool rigidity enough. Processing efficiency is 20 times of coated carbide inserts.

2. Auto parts engine block processing

Automobile parts engine cylinder mainly adopts milling processing, Halnn superhard latest launched overall cubic boron nitride inserts BN-S300 grades, can high efficiently milling engine block. Such cutting tools are more resistant, higher processing precision, overall rigidity and stability is very good, especially suitable for the milling engine cylinder surface.

Halnn superhard CBN inserts BN-S300 grades fine milling engine block cutting parameters: ap = 0.3mm,Fz=0.12mm / r, line speed n=2800,Vc=1700m/min. Compared to imports PCBN inserts, 3670mm/min feed rate, Halnn superhard BN-S300 grades cubic boron nitride cutting tool life is higher than imports PCBN cutting tools, and cutting tool costs is less than imported PCBN inserts.

3. Auto parts belt pulley processing

Auto Parts belt pulley finishing cutting tool selection BN-K20 grades. BN-K20 grades cutting tools are mainly used for gray cast iron fine finishing procedure. In addition to the processing belt pulleys, Halnn superhard BN-K20 grades cubic boron nitride inserts can also be processed clutch pressure plate, flywheel, axles axle housing and other gray cast iron materials.

Cutting parameters: ap=0.3mm, Fr=0.25mm/r, Vc=550-700m / min. Compared to coated carbide cutting tools: not only ensures a good belt pulley roughness and cutting tool life is 5.5-6 times of coated carbide cutting tool.
