The solutions of CBN cutting tools machining auto cast iron parts
Auto parts are made from gray cast iron usually has a variety shape.When choose the cutting tools to machining these auto parts, we must consider the work piece gap,can’t have any interference.
CBN cutting tools can offer various structural characteristics of automotive cast iron parts.Select different cutting tools model number according to different parts,it not only increase productivity,but also reduce the processing costs.
1.Machining Auto parts disk brakes
① Roughing:Select non-metallic adhesive CBN insert BN-S30 grades.
It is also suitable for the finishing process,when roughing disk brakes,we often choose rhombus inserts and square inserts.It has high processing efficiency,and also get well precision.For example,CNMN120416,CNMN120718;SNGN120412;SCGN0904 grades are usually used for roughing disc brakes CBN insert.
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.-speed cutting efficiency high;
6.Dry Cutting reduce environmental pollution;
②Fine finishing:Cubic boron nitride inserts BN-K20 belong welded CBN inserts

It only suit for a small margin for fine finishing process.It has many models,such as the triangle,rhombus,and international model 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. Machining Auto parts engine block
Automobile parts engine cylinder mainly adopts milling processing,China launched solid cubic boron nitride inserts BN-S300 grades,can high efficiently milling engine block.Such cutting tools are more wear-resistant,higher processing precision,overall rigidity and stability is very good,especially suitable for the milling engine cylinder surface.
BN-S300 CBN inserts 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,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. Machining Auto parts belt pulley
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,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.
