Tooling Help! Live Centers

stenger · May 18, 2018

I am trying to find a solution to a work holding problem. I am looking for a tool that incorporates a MT3 taper and a live collet holder. I am trying to hold onto a cylindrical part for support while performing a 4th axis operation. I am unable to use a conventional live center.

Any help would be great

I've seen live 3-jaw chucks for tailstock use, but not a collet receiver. However, I'm a manual shop and have no idea what might be available in the cnc world.

I saw one being used in an online vid but I cant find one for sale.

Post the video. Maybe someone can help.
I know this isn't a collet, but this is what I use. Mine is a 5" with 2 piece jaws and "set-tru".

If this is a slow rotation,and a small diameter,low volume,just get a blank morse taper and drill and bore a precision hole. Slather on some center lube. Edwin Dirnbeck

If it is a hollow tube you are working with, make a plug to fit inside it that has a center drill mark for your live center to engage.

I will be gripping on the outside of the part.

Sounds like a pick off on a swiss or other automatic/cnc lathe

Only, your not driving it with the tailstock.
