BNK30 CNC Brazing CBN Inserts Finish Turning Cast Iron Engine Block With Better with high efficiency

 

 

1. Halnn Tools BNK30 CBN Inserts Boron Cast Iron Cylinder Liner

The cylinder liner of the automobile engine is a cylindrical part placed in the hole of the cylinder body of the machine body, and the upper part is pressed and fixed by the cylinder head. The piston reciprocates in its inner hole, and its working environment is very harsh. Therefore, the cylinder liner should have sufficient strength, rigidity and heat resistance, and should have good wear resistance.

 

 

2. Why we choose Halnn Tools BNK30 CBN Inserts Boron Cast Iron Cylinder Liner

 

Most of the cylinder liners are made of wear-resistant cast iron such as boron cast iron and alloy cast iron. Since these cast irons have high hardness points, the tool wear is large. When cutting with a carbide tool, the cutting speed is low, the tool wears quickly, it is difficult to improve work efficiency and machine efficiency, and some materials are difficult to grind.

As a new type of super-hard material tool, CBN insert revolutionized mechanical cutting technology. It provides an economical and efficient cutting method for difficult-to-machine materials such as wear-resistant cast iron. A large number of facts prove that CBN inserts are in line with the development direction of today's tools - improving life, improving cutting efficiency, reducing processing costs, ensuring high precision and low roughness, and meeting the processing requirements of difficult materials.

Wet Cutting

Machining effect: Compared with coated carbide tools, the cutting speed of Halnn Tools BNK30 CBN insert is more than twice that of coated carbide inserts, and the service life of the tool is 4 times that of coated carbide tools. Above, the processing efficiency of the boron alloy cast iron cylinder liner is doubled. For the mass production and processing of the boron alloy cast iron cylinder liner, the BNK30 material CBN insert is used to improve efficiency and save cost.
