Hi guys, new to the site and also new to Mazak!!
Wondering if anyone could offer any suggestions for a problem we have with a Nexus 510c (Heidenhain iTNC530)?
The Y axis will make a whining/groaning noise towards the back of the stroke, but only after a long move or continuous back and forth movement in that area. Only seems to do it above 90% feedrate and also when the X axis is all the way over to the right.
If the X axis is centered or over to the left, the noise in Y is either very quiet or not there at all.
When the Y axis is making the noise I can feel it in the front bearing housing (if I hold a screwdriver on it). I have turned the ballscrew by hand (with a spanner)with motor still attached, it doesn't feel notchy nor over tight, although I do have to use a spanner to turn it.
It has been suggested it could be the Y axis thrust bearings, but would this tally up with the noise being present/worse when the X axis is over to one side?
Apologies, I am electrically biased and from a background of bespoke CNC grinders, automation and lathes - I have zero experience with Mazak, and limited experience with CNC mills!
I spoke to Mazak service about the problem but they didn't have any suggestions other than sending an engineer out.
The machine is not alarming out and the finish/accuracy has not been a problem for the job it was on when making the noise, but the noise is stilla concern!
Any advice much appreciated!
