//angled calibration sphere//

Anyone know why anyone would need an angled calibration sphere? My company has one and I want to replace it with a regular vertical calibration sphere!

If it has 2 spheres it is needed for calibrating a star probe in various angle configurations as a single ball won't accomplish all angles without shanking out.

Oh okay thx I never need to use a star probe, I just use a disc probe instead. Other than that no need for an angled calibration sphere right?

[Jim Poehler]

Not that I know of.

I use the angled sphere if I have to calibrate a right angle probe where the tip is facing up.

After reading your post. It may have clear my problem.
When I am calibrating the probe has been shanking on the post of the calibration sphere. its a sharp angle, if that makes any sense. if I were to guess um, A-115, B90. almost facing all the way up. Its a vertical small sphere .663, just a guess. But when I change it to the 1 inch sphere it doesn't shank. Could it be best to use a angle calibration sphere as FUNKWAT? or do I have a different issue?

Also, would I be getting a wrist angel error if the probe is facing all the way up?
