CBN wheel recommendation.

Rorschach · 6 Jan 2021

I have decided to upgrade to a CBN wheel. I have the axminster 8" slow grinder which currently has a 30mm wheel on it. The spindle is either 18mm or 32mm depending on if you use the bushing or not. Supplier recommendations?

I will be sharpening HSS (metal) lathe tools mostly. I currently use a 120grit wheel, should I go for the same in CBN?

Anything? My google searches have not been very helpful as the results are heavily US skewed, even when adding UK to the search terms.

For a while Lee Valley here sold a 1 hp Rikon slow speed grinder with CBN wheels and tool rests as a package aimed at turners. It had an 80 grit and a 180 grit wheel on it. A 120 grit could probably serve in a single wheel setup.

Are the Axminster variants no good? Abtec do some but I remember them being quite narrow.

Just remembered that toolpost used to carry some, may be worth a call to Beaufortink (who’s taken over for some items) to see if they are going to continue supplying?

Axminster are out of stock and I don't think what they had was suitable anyway.

I'll try Beaufortink, they don't list anything on their site though.
