Wobbly spindle, what's causing it please?
I have an XYZ 1500 mill (looks like a Bridgeport) with Protrak AGE 2 CNC and the finish is crap.
I know it's slightly out of tram in X, but more worrying is the fact that the bit wobbles at it's end (like the bit is bent).
So I got a bit of bar stock and stuck it in the spindle and at six inches length from the collet the runnout is about 1mm(!). Next I stuck another R8 collet in and still got a wobble- a bit less, but definately there.
*scratches head* what would cause this please?
Oh, I've cleaned both collets scrupulously and the collets too.
Many thanks in advance!
I love deadlines- I like the whooshing sound they make as they fly by.
