I've been trying to wrap my head around this question. This comes up when we have one of our CNC lathes that gets bumped or crashed and we are dialing in an ID toolholder to get it back to X zero.
I can use a coaxial indicator mounted in the chuck and sweep it and it will look fine. When I use a test indicator mounted on a mag base it is still way off. I realize you really have to be careful with spindle droop when using a mag base for this. Anybody have a suggestion what mag base or attachment works best with the least fighting droop?
My thought is that with the co-ax depending on the length of the attachment and it is different how much you you move X to get the dial to move on it.
I'm not sure this makes any sense, but are there any thoughts?
