How much CBN circumferential wobble is acceptable?
I have three high quality 8" CBN wheels mounted on two different grinders. Composite stone wheels faces can be trued up with a diamond tool or special stone. That obviously can't be done with the CBN wheels.
This is the best way I can describe it:
When the grinders are shut off and slowing down, if I hold a tool on a sturdy rest and just ever-so-slightly touch the tip of the tool to the spinning wheel, it sounds like ring of an old fashioned telephone bell as the steel grinding wheel body rings with each light bump of tool. It is not severe, but it is noticeable even when the machine is fully on.
Is this common?
Is it my grinders (Jet and Dayton)?
Can anything be done about it?
Thanks,
TA
