CNC table re-finishing

[CORBIN92087]

I've wondered this for sometime now...Is it common for CNC users to periodically regrind or refinish there table in the machine? Ive noticed the last couple of times switching in and out vices and jigs, that our table isnt quite as smooth as it once was, which no ****...its gonna happen sometime. So what should be used to re-finsh???

It is common to stone the table from time to time. I don't think you would need to re-face it.

Where can I purchase the stone at?

I actually cut the table on my Fadal 4020. I used a 9" fly cutter, that I welded and gusseted to a holder. It was crowned about .005" in the the X direction. About the last 8 to 10 inches of the table were low. It's not a big deal to do it, but I wouldn't do it if the table is still flat.

Nice welds, but that must have generated a lot of heat. Did you have to re-machine the fly cutter to true it up after you added the braces?

Luke,
Generally any stone will do. I use a stone that is really supposed to be for knife sharpening.
