Engine cylinder liner is installed in the cylinder bore, in order to have the heat load and mechanical load capacity, it needs sufficient strength and stiffness, the workface needs a high precision and finish, excellent wear resistance and corrosion resistance. Therefore, the engine cylinder mainly is made of cast iron, such as alloy cast iron and boron cast iron.
With the continuous development of the automotive industry, the production of the engine cylinder continues to improve. while ensuring product quality, efficiency and cost is also one problem that the engine liner need to think, So they will require high on the cutting tools life, processing efficiency and the stability.
Halnn, professional hard materials cutting tool experts, with long-term accumulation of technical strength and strong technical research and development team, successfully developed solid cbn insert, widely used in the field of cast iron. For the engine cylinder liner, Halnn researched BN-S300
solid cbn insert grade, which can achieve high efficiency and lower the costs.
BN-S300 is solid cbn insert, is installed on the indexable tool holder, which is easily operate. With BN-S300
solid cbn insert machining cylinder, it will produce large qty heat, some of them are taken away by the chips, which will make sure the good surface quality of the product.
Example: Machining the cylinder with BN-S300 solid cbn insert
Machining Materials: Boron Cast Iron
Machining Part: Cylindrical
Machining Process: Finish machining
Insert Model: BN-S300 SNGN1204
Cutting Data: Vc=850m/min, Fr=0.25mm/r ,ap=0.5mm
Machining Type:Wet Cutting
Compared with some brand ceramic cutter, the cutting speed can improve about 1.7 times, and the tool life will improve 4.8 times, the processing efficiency will improve several times.
BN-S300 SNGN Solid CBN Insert has 8 cutting edges, and both the double side of the cbn inserts can be used, it can be used both roughing and finishing process, and has excellent wear resistance and impact resistance.
