Abrasive machining is not considered to be a precision grinding process, but that's not to say it isn't precise. Abrasive machining can take the place of "large-chip" machining processes like milling, planing, broaching, and turning. Compare the surface finish and the precision achieved with the large-chip processes to the surface ...

Such materials not only preserve the life of the wheel but also help it push through concrete. Besides grinding concrete with these types of discs, you can also use them to grind granite, stone, marble, masonry, and similar materials. Although a concrete grinding wheel can offer great longevity, these tough discs eventually wear down.

Turning is very similar to 3D profiling in that the stepover, in this case determined by the feedrate while turning, results in scallops that match the shape of the turning insert. We use this to good effect when turning threads, but if we want a smooth shaft, we'll have a surface finish requirement that must be met.

If surface finish matters you might need to make coolant-fed pads for the rests, or plan on a post-grind buffing using a belt sander or similar (like they polish crank journals with).

After all, the process looks very similar. Concrete burnishers, also called power trowels or helicopters (so named for their rotating blades) are mechanical, and they spin in a similar fashion to a concrete grinder. But the similarities end there. Burnishers aren't powerful enough to grind down a concrete surface.
