CBN Grinding wheel trouble

[tinyjames]

I'm after some advice or help tracking down Bushings for my Grinder

I have a grinder with a 12.7mm shaft and a Tru-Grind CBN wheel with a bore of 15mm, now I can't believe I'm the only person that has had this problem.

Axminister sell bushing for larger bore's but not the 12.7 mm bore.

the wheel dimensions are 150mm x 40mm x 15mm with a bore of 15mm

I could exchange the wheel for a 150mm x 25 mm x 10mm with a bore of 12.7 but I really feel this wheel is to narrow for a 1" skew chisel and this is not a route I want to go down
So does anyone know of a supplier of the bushing needed

I haven’t read the spec but if you search for 12.7 to 15 bushing adapter on the auction site you get a few hits.

thank you for the advice I have ordered two bushings but they will not arrive until the new year so as a get me by I have ordered 15mm nylon rod so I can drill it out to 12.7mm or 1/2" just hope it will work if not I will have to go back to my white grinding wheel until the new bushings arrive

Careful if you use a bushing CBN wheels are heavy if it runs out of true.

Any machine shop could make one of these in no time

Slightly over size but maybe it could be reduced a bit?
