With the rapid development of modern technology, more enterprises producing gray cast iron adopt CNC machine tools to improve production efficiency and reduce processing cost.The universal application of CNC machine tool also enables the cutting tool industry to continue to develop.Besides，In the field of gray cast iron processing applications, cubic boron nitride tool gradually replaced the traditional carbide tool.
As a leading brand of professional hard material processing Tools, Halnn Tools provides a variety of green and efficient cutting and grinding Tools and solutions.We manufacture and sell the products of two leading brands - cutting tools and grinding tools.We also undertake the super hard heat - resistant wear - resistant spare parts or tools to develop custom business.Halnn Tools has professional cutting Tools products in the field of finishing gray cast iron. They are CBN insert BN-K20 and BN-H11 .Both of them are cubic boron nitride cutter.Their processing effect all obtains the user's affirmation.The following is a brief introduction to the above two brands of the difference.
First of all, the similarities are that BN-K20 and BN-H11 are both welded cbn tools, and the cutting depth of them cannot exceed 0.3mm.
The difference is in terms of durability, the cutting speed of CBN insert BN-H11 brand is about 350m/min tool which is more durable. While CBN insert BN-K20 brand is more durable at high speed.

The following case is about gray cast iron processing with Halnn Tools CBN insert BN-H11 brand.

Processing Effects compared with coated carbide cutting tools:
Efficiency has been significantly improved and overall production costs have been reduced.
There are more enterprises which pay more attention to efficiency will choose BN-K20 brand CBN tool.

The following case is about gray cast iron processing with Halnn Tools CBN insert BN-K20 brand.

Processing Effects compared with coated carbide cutting tools:
Compared with coated carbide tools, the single insert life of BN-K20 cubic boron nitride tool is 5.5-6 times that of coated carbide tools. Besides, its surface roughness can reach ra0.7-1.6.
