Small Collets

[graemeian]

I want to build a special operation lathe using a collet system to hold the part. I would like the pull type such as the 5C or the R8. However, I am looking for something smaller. My part is 1/8" in diameter, I would like to adapt a pneumatic draw bar to tighten the collet. I am looking for a small collet system. Is there anything available?

Thank you.

Look for a 3C collet system (goes as high as 5/8" diameter), Hardinge makes collets this size, as well as emergency collets that you can bore out to whatever size or shape you need.
