Rebuilding cnc

[rgollar]

I am looking at some used cnc and my question is one is a linear rail and one is a box way. In the long run when they need to be rebuild which is easier to rebuild. Would changeing the linear rail be easier to change with the bearing than a box way needing to be rescrapped. Just wondering if any one had any thoughts between the two when it comes to rebuilding them. Thanks

The salesman always told me , "ya just slap some new linear ways on there". " "Boxways are much more difficult"...I have not had either done.

By Far linear ways will be much easier to rebuild.

 

BUT, it takes a lot or a lot of mis-use to damage these. With all the used machines on the market now and the low prices, you should be able to get a great machine cheap and I don't think you will need to worry about this issue for a long time.

 

Get a machine that has been well cared for and care for it the same when you get it.

Very true. 2 quick ways to ruin them are improperly mixed coolant and machining graphite. If I see a rusty machine I would look it over very carefully. A duplicating shop closed up several years ago (went to auction/forclosure)and I did not see much in the way of vacums when they made electrodes and one mill did have new linear ways recently and I wonder why.
