Two CBN grades were used for the tools: 7015 and 7025. According to the tool supplier (Sandvik Coromant, 2006), the CBN7015 grade (CBN-L) is a material with low CBN content and an added ceramic phase, while the CBN7025 grade has a high CBN content (CBN-H).Two types of ceramics were also used: CC670 and CC650. According to Sandvik Coromant (2006), the CC650 grade is an alumina-based mixed

CB7525 is a very tough grade and contains 90% CBN with fine grains in a ceramic binder. It is designed for grey cast iron machining and also performs well in hard part turning applications in heavy interrupted cuts (short contact time) as well as in very abrasive steels (tool steels, manganese steels). CB7925 contains 75% CBN in a ceramic binder.

Cubic boron nitride (cbn) inserts are used for iron-based alloys (e.g., cast irons, hard steels, iron-based composites). cbn is thermally durable up to around 1200 ºC (2192 ºF) and has high a strong defiance to chemical attack as well. Therefore, you face no problems when machining hard ferrous metals and performance is substantially better

Cubic boron nitride is the second hardest material in the world invented successfully in 1957. The hardness of CBN’s single crystal is HV8000-9000 while the hardness of PCBN is HV2500-5000, so its abrasive resistance is considerably better than tungsten carbide and ceramics.

The machining of hardened materials with hardness over 45 HRC has been an alternative to grinding since the 1970s, with the commercial availability of cubic boron nitride (cBN) and ceramic tools.

1. Introduction. Hard turning, a process of single-point cutting of materials with hardness above 45HRC, has emerged since modern ceramics were first made available for continuous roughing and cBN tools for continuous finishing .Finish hard machining has been a beneficial practice for machining industries due to its high productivity , , an option for dry machining, improved surface integrity

Sandvik Coromant’s CB7035 CBN grade uses a ceramic binder in conjunction with a design that combines a mechanical interlocking shape with traditional brazing techniques to increase insert strength. Compared with grinding, hard part turning provides the advantage of allowing much more machining to be completed in a single setup.

I would use a CBN tool from someone like Sumitomo. You might get some salesman to let you try a CBN insert or brazed tool as the CBN tools are sometimes more expensive than diamond. CBN works well on very hard steel Rc60-62 if you have a very stiff set up. Chrome is in that range of hardness so CBN should work on it and last better than diamond.
