Smaller dia grinding wheels have higher max RPMs, and it looks from the machine pics like the saw blades are pretty small diameter so a grinding wheel in their place would be similarly small. The necessary wheel is probably $20 or so. I also think the offset correction table is probably workable, but it's nice to have things as mechanically perfect as possible to start with.

How well would a grinding wheel work > with that? Spindles only go to about 4000 rpm. And what is max rated speed for grinding wheel? AFAIK it is not much higher than 3000 RPM. There are special wheels also for aluminium. But I think that applying offset to Z position to compensate for bed flatness error is a lot more cost-effective solution.
