What do you mean "run across the Y axis"? Where was the indicator mounted, and how was it moved?
.025 sounds fishy.

I owe a Quantam/Kasuga 60x30 CNC Mill, running indicator across "Y" axis gives me a total of .025 error. Could i just take a fly-cut acroos entire table to make flat? Or what other methods to repair this issue?

Exactly ".025 sounds fishy"...
indicator mounted on spindle
MrMagooo,
Inspect the rails, trucks and ball screw for pitting/roughness to be sure they are not the culprit or you could be chasing that .025 forever.
Is that .025" or .025mm?

MrMagooo,
If this difference seems to be in one spot then that would seem to me to be indicative of a bad section on the rail. ???
That is a big machine. Have you checked it for level lately?
No way would I face the table off. There has to be some other problem. Have you tried various 'pry tests' on the table and vertical head to see if you have detectable movement on any rails/ways?
First you get good, then you get fast. Then grouchiness sets in.

In particular check for levelling screws hidden away under the machine in addition to the ones at the corners which are easy to see. It is possible to apparently "level" a machine just from the corners but if the inner screws are not helping support things the whole machine sags when the Y axis is run in and out.Originally Posted by HuFlungDung
I would use a straight edge to insure that the problem is with the bed or bed alignment and not in the rail system of the spindle (gantry).
It is a general, unwritten rule NOT to disturb a factory surface on a machine - especially a table unlsee it is proven to be out or damaged and no other options exist. I doubt the table is cupped or whatever - you are likely seeing the product of wear. I would strongly suggest finding the error instead of cutting the table to compensate.

Consistency is a good thing....unless you're consistently an idiot.
sounds like an out of level condtion to me.
