Expanding Mandrel, turning/ production

[mkd]

Any one got a tooling source / method?

second op needs to hold a 1.0 dia bore of a 1.3" long part.

Macturn has an 8" Kitagowa hyd 3 jaw.

 

need to thread, mill hex (@B0 or B90), face OAL.

 

anyone ever load multiple parts on a single mandrel with center support?

would be nice to have two mandrels; one in/ one out.

 

opinions?

ah, yes.

Hardinge has them too. They require a form filled out to match up with your draw tube. Don't think i have the lead time for all that.

 

might have to settle on something to load in the 3 jaw. Pitfalls?

as far as multiple parts check out speedgrip mandrels, specifically:

I have turned the jaws on a 3-jaw then opened the jaws to clamp on ID.

You might want to consider Mitee-bite.

You might want to consider Mitee-bite.

only think of them for milling..

 better adjust my thinking.

 

i got a cheap mandrel locally. one part at a time with a center screw. Gotta finish these by the end of the month...
