High Speed Turning Boron Cast Iron Cylinder Liner With Halnn Tools SNGA120412-8S CBN Insert

 


 

1. Halnn Tools BNK30 CBN Insert Turning Boron Cast Iron Cylinder Liner

At present, CBN tools are widely used in foreign processing cylinder liners. This is because the cylinder liners are mostly made of wear-resistant alloy cast iron such as boron cast iron, boron-copper alloy cast iron, etc., and these wear-resistant alloy cast irons have high hardness points for the Inserts. The wear is very large. When the cylinder liner is processed, the cutting speed is low, the tool wears fast, and the working efficiency is difficult to improve. The use of CBN tools can greatly improve work efficiency, product quality and reduce processing cost. Therefore, more and more domestic Cylinder liner manufacturers use CBN Inserts to cut cylinder liners into new processes and technologies.

 


 

2. Why we choose Halnn Tools BNK30 CBN Insert Turning 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.

6.Application Case 

 

Machining Process: Machining Cylinder Liner  

Workpiece Materials: Boron Cast iron Cylinder liner

Insert Grade: BNK30

Cutting Parameters: Vc=850m/min,Fr=0.2mm/r,ap=0.3mm

Processing Type: 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.
