Hi all, I am new to this forum.
What is the expected accuracy and lifetime of a SX3 cnc ( with proper maintenance & machining condition ) ?

That's a good question!

I'm awaiting an answer by your side...

I asked the question because I want to buy one, but as this is a big money for me, I must carefully calculate the cost

long term accuracy, your gonna need to replace the acme screws with ballscrews.

I don't really see any other fault in the mill.

You'll need to replace the gibs over time. The x/y gibs are nothing but strips. I'm unsure of the z-gib. I haven't taken that apart.

I wish there was slightly more travel on the x, but as it stands it's pretty good for having a square column.

General question:

How long has the X3 been out, and who out there has really put one through the paces over this length of time?

Might make a good survey question.
