Hi I am considering buying a CBN wheel to use for sharpening lathe and mill tools.

Axminster sell a large wheel that is electroplated with CBN. All the T&C grinders I can see in back issues of MEW use cup wheels.

When I search for CBN cup wheels I seem to just turn up ones that are resin bonded.

Questions are;

Could I use an 8" wheel to sharpen mill tools or do I need a cup wheel?

Does any one know about the life time of resin vs electroplated CBN wheels?

I use an 8" plated wheel on an ELU grinder with an Acute grinding system.

I bought one of these cup wheels (ebay No. 281852200370 ) recently and may be suitable for you. I believe it is diamond rather than CBN but the coating is electroplated and the wheel seems to be nicely made. I have not used it yet but looks promising. The body is steel and quite heavy which is probably no bad thing. The blurb says it is suitable for carbide and HSS. Three weeks from China is a pain but the price is very good.

I bought a 6” cbn wheel from “The Toolpost” 18 months ago. Delivery took a while and it was not cheap but I am happy with it. The balance is excellent and it is partly coated on the flat side of the wheel.
