    Default Ballscrew Repair Needed

    Hi all,
    I have a Bridgeport Interact II with a Heidenhain TNC 151B controller. I have .009 backlash in the x axis. The backlash is in the nut for sure. I verified it by using a dial indicator on the end of the ballscrew and there was no measurable movement on the shaft itself.
    I used a pry bar, and by applying pressure on the ballnut I was able move the nut about .009.
    I put .009 in the controls backlash parameters but there was no difference.
    Has anyone sent their ballscrews out for repair? if so, do you have a recommended source for this service?

    Hi Ihave repaired a couple of ballscrews when the need arose. It may be a double nut type and you may be able to make a wider spacer washer to go between the two halves of the nut but remove all the ball bearings first and examine them from pitting and wear. Also examine the insides of the nuts. If all is good there a wider spacer may fix the problem. Also it is possible to get various size balls going up in small increments of size so a slightly larger set of balls may fix the problem but they will not need to be 0.09mm bigger but probably about half that much. It will depend very much on whether the Ball Nut you have is good inside or not and the ballscrew itself is good. Hope this helps.

    I have had excellent experience using Barnes Ballscrew in Michigan. They do a great job.

    Thanks IndyGreg, I will keep that in mind but over on our side of the world we tend to give things a go ourselves first, usually we are in a hurry, plus shipping to the US and back is very expensive. It is good to know who does these things. Thanks Russel
