CBN Grooving Tools For Cast Iron Cylinder liner Cutting Tools/Cylinder Tools

1. Advantages of Halnn CBN Grooving Tools

1.Comparing with other CNC tools, it can realize high cutting speed and improve the process efficiency.

2.Comparing with coating carbide insert, the tool life will improve about 9~15 times, and the costs only about 7 times of coating pcbn inserts, which is more economic.

3.With Halnn CBN Grooving Tools, the surface roughness and precision both get improved.

4.We can offer customized service as the customers' requirements.

2. Halnn CBN Grooving Tools for Cylinder liner

Most cylinder liner are made of abrasive resistant cast iron, such as boron cast iron, alloy cast iro, ect. All of them have hard pots, so it will wear rapidly with tungsten carbide tools, and also some materials can't machine with tungsten carbide inserts.

CBN tools, as one new superhard cutting tools, make it possible process the wear resistant cast iron with high hardness and make sure the high precision, good surface roughness and improve the cutting efficiency.

Halnn has researched new cbn grade BN-S300 and BNK30 specific for gray cast iron machining, both can be used for roughing and semi-finishing process. The following is cutting parameters of BN-S300 and BNKK30:

Machining Materials	Process	Cutting Speed Vc(m/min)	Cutting Depth ap(mm)	Feed Rate Fr(mm/r)	Recommend CBN Grade
Gray Cast Iron	Roughing	400-1200	1-10	0.2-1.0	BN-S30, BN-S300
	Finishing	600-2000	≤1	0.05-0.3	BNK30, BN-K10, BN-K20

Zhengzhou Halnn Superhard Materials Co., Ltd is a high-tech enterprise specializing in the production of ultra-hardened tools, and the leader of professional hard material processing tools in China and the first to research new cutting tools specific for gray cast iron, kinds of wear-resistant steel/cast steel, hardened steel materials.

The predecessor of Halnn Superhard Material Co.,Ltd is Henan Superhard Material Institute which is the earliest to make research on processing the brittle and hard materials with cubic boron nitride tools and High-Grade Diamond Tools. As the pioneer of Industry tools in China, Halnn adhere to the initial business philosophy of "Not seeking large and complete, only insist high-precision and professional". With more than 10 years experience, Halnn has researched one by one new materials grade, new technology and become the most famous cutting tools brand in superhard cutting tools industry.
