What do you mean when you say “fine diamonds at a high angle and RPM should be breaking off the burr”?
Specifically, what do you mean by “breaking off the burr”?
My thinking is that a 0.5 micron particle is extremely miniscule. Also the amount of abrasive particles in compound is very small and what little there is, is distributed throughout the compound. It’s a lot like a very poorly manufactured abrasive belt with very few, randomly placed abrasive particles that are poorly adhered to the belt substrate.
I just try to imagine exactly what impact that has on the burr. While I have no proof, I would suspect that it acts like any other fine abrasive and may remove a minute amount of steel. Basically, just continuing the sharpening process at a very fine level.
This may very well abrade away some of the burr, and because it is such a fine abrasive, create less burr than is abraded away. I do know that very fine abrasives like that will remove very fine scratches, polish the bevel and further smooth the edge even if only a very small amount.
Obviously, unless you have created a really big, mean, nasty and tough burr it can be removed by repeated bending back and forth until it fractures off using a plane leather strop and doing it by hand. But that can take more time than I like so I use the Kally @ 1750 RPM – (about 1800 ft/min) belt speed. That said, I don’t really understand how the moving belt impacts burr removal compared to just bending it back and forth. I’m still trying to figure out exactly what that means.
Anyway, that’s my thinking when I ask, what do you mean when you say “fine diamonds at a high angle and RPM should be breaking off the burr”?
