I have looked at them -- they are available in the US.

A pro woodturner in Eugene Oregon uses and swears by them over the diamond wheels some are using. They work effectively for the proturners --

They do require being sent in to be retrued occasionally - and supposedly outlast diamond wheels.

so -- how many premium grinding wheels do you wear out each year??? If you are going through several you probably need to move to something like this.
 
CBN wheels used for production grinding processes sharpening tool steel and HSS almost bet involves some type of tool holder and feed mechanism. Bet industry selective on what they sharpen on CBN and diamond wheels too.

Peter Child kind of a pioneer in modern woodturning taught for many years. His book The Craftsman Wood Turner out of print but still available. Go to Google books and will find some articles where Peter Child talks about free hand hollow grinding sharpening on 6" grinder with no guards and running at 3000 rpm.

Think his son runs the family business Peter Child link posted here. Peter Child occasionally post on Wood Central turning message board.
