Hi
In a VMC I have a part which is a ring with a simple hole circle in a certain pitch diameter. The part is positioned by a properly fitted pin and is free only to rotate. Now i want to rotate my part in its pin so that one of the holes is properly aligned with X or Y axis.
How could this aligment be made?
Thanks
 
Find center of the ring.
Move in X to the radius of the bolt circle.
Use a holder in the spindle with a pin the size of your hole.
Jog down carefully in Z til the pin is in the hole.
Clamp part.

only thing to add is i use a .001 or .002" smaller pin in a hand tightened collet so if hole not aligned it just pushes pin into collet. normally to get pin close and handle mode adjust you can get within .002 fairly quick
 
I usually cut soft jaws for stuff like this.
Cut your OD of the part. Then drill & interpolate a pin hole in the correct position with respect to your bolt hole circle & geometry of the part.

Stupid question,but is that pin that you're using to rotate the part in the CENTER of the diameter?

Boy I'm sure glad I took a sip of my afternoon coffee before I read this one.

Hello Brent,
assface421 is taken. It was suggested some time ago that the user of assface421 settled on that handle because assface420 was taken. Therefore assface with a suffix exceeding 421 may be viable.

I'm not sure if all suffixes prior to 421 are taken, but assface181 is one that one may be able to get their teeth into.

Regards,

Bill
