Manual three jaw chuck with optical encoder
Manual three jaw chuck with optical encoder
(OP)
Hi everyone,
This is my first post at eng-tips, so I hope I'm in the right place. I am looking to either build my own or even better purchase a manual three jaw chuck for TIR gauging of castings. Currently we chuck a part up, position an indicator on the feature we want to measure and manually/slowly rotate the part. I would like to find a system that has a three jaw chuck attached to an encoder of some type so that I will be able to automate the data collection from the unit. Has anyone seen something like this? Sound reasonable?
Thanks,
Fred

Some years past when I was making pistons for a living, there was an apparatus called a Tallyround that did what you describe. Very accurate and gave a good representation of the ellipse we wanted. A bit pricy as I recall though.
