That’s going to be the next job I think. Spindle itself is running true as I’ve clocked it off the collar and the spindle nose itself-0 runout.I'd mount the 'collet chuck' in the mill and a lathe tool to the mill table and skim the OD. Should then show no runout. Stick that in the 4 jaw on the lathe, clock it, then recut your taper for the ER40 collets
No and no, fixed head.i'm unfamiliar with your mill, but does the head tilt? And does it have a quill?
Ah shame you could of cut the taper in situ.No and no, fixed head.
I’ll work I’m sureAh shame you could of cut the taper in situ.
