Good morning all, I hope that everyone is well. Some time back, I had a job for my Sodick AQ 750, that required some 0.197" +/- 0.0002" features, both holes and slots in a 0.200" thick plate. Prior to starting the job, I cleaned and aligned the guides and head...did everything that one would expect to need to do in order to achieve the desired result. Well, I had a difficult time with hitting the tolerance, both diameter and roundness. As it turned out, the C guide, located below the lower guide had a pretty healthy groove cut into it; once changed, the features cut to spec...multiple cuts of course. My quandaries are A) why/how does this worn guide effect the cutting of this feature, and B) why was this worn so much? The wear was in the Y+ direction of the guide. Since that occasion, I have taken the lower head apart, and have noticed the same issue with the C guide; a notch worn on the Y+ side. The guide itself is sapphire; apparently a diamond one is not available. Regardless, the issue is still occurring, the Sodick rep doesn't have an answer....does anyone?
