I'm refurbishing my 1988 Lagunmatic CNC and I have reason to suspect the ball screws are worn out. The previous owner told me it probably needed new ball screws and i found that the table had several thou of play in X axis before I disassembled it; I should have done better checks to determine whether it was in fact the ball screw or the thrust bearing. But I got ahead of myself and just took it all apart, including (unintentionally) unthreading the ball screw from the ball nut, so the balls are now loose in a ziplock bag. I don't want to waste a lot of time trying to reassemble it to verify it's worn before sending it off. I'm pretty confident that it is, so I'd rather just send it off to be checked out by someone less stupid than me, and re-ground/re-balled if possible or quote replacement if not. So where do I send it? Is there anywhere near Houston TX known for doing a good job so I can just drop off & pick up locally? How much does a ball screw refurb typically cost?
