CBN tool interrupted cutting hardened steel parts

Halnn, formerly known as Henan Superhard Materials Research Institute. As a CBN tool production base in China, it is

constantly innovating in CBN tool development technology and always leads other manufacturers in the superhard

tool industry. Through continuous research and practice, Halnn has made a major breakthrough in the welding CBN tool,

breaking the statement that CBN tools can not be interrupted.
 


BN-H20&BN-H21 grade CBN tools from Halnn, and the structure is shown below.



 

The most obvious difference between the two grade CBN tools is the cutting edge. The cutting edge of the BN-H20 grade 

CBN tools can be used both above and below, while the BN-H21 grade CBN tools has only one side available. If the 

required accuracy is not high, it is a slight intermittent cutting condition, and the BN-H20 grade CBN tools is selected. If the 

precision is high and it is a strong intermittent cutting condition, the BN-H21 grade CBN tools is selected, and the effect is 

remarkable.

The case of interrupted cutting hardened steel is as follows



1,Semi-interrupt cutting hardend steel parts

                            



2,Heavy interrupt cutting hardend steel parts

                            

The above two CBN tools are widely used in automobiles, molds, bearings and other fields due to their outstanding 

performance advantages. Halnn, the first brand of Chinese national knives, has absolute production strength and technical 

capabilities, and is committed to making the world no longer difficult to process materials.
