We see from your search that you're looking for information on the term "CBN Wheels",
and we have a large number of manufacturers' news releases and technical articles here on Manufacturingtalk which will be of interest.
Let me be your guide.
Start with
the news release Grinding crankshaft pins and bearings in one from
Emag UK, which we summarised at the time by saying "A cylindrical grinding machine built for machining passenger car engine crankshafts up to 500mm long, grinds pin bearings and main bearings in one set-up".
A couple of weeks before,
we featured the news release CBN form grinding wheels offered from
Engis (UK): "Electroplated CBN wheels offer substantial benefits - particularly when grinding exotic alloy steels; the tough crystals stay sharp longer as they tend to be self sharpening under cutting stress".
In November 2007, we covered the news from Tyrolit
concerning its Polaris and Genis superabrasive wheels
- take a look at OD wheels grind hard/'exotic'/tough alloys
which says: "Two ranges of external cylindrical grinding wheels have been introduced for large volume production of components from difficult materials such as hardened steel and tough exotic alloys".
Take a look also at the news release from Danobat Group, Cylindrical grinding developments shown,
as well as Affordable drill sharpener is modular from Kitagawa Europe,
and Modular grinders chase crankshaft pins from Emag UK.
