here's a basic list

you need to measure these - its hard to tell by looks, there are seemingly endless styles and sizes. still, you may not get an answer, there are just too many possible collet standards or even proprietary ones

Do you have any pictures that show the back end. These look like what are called 2D collets used for holding bar stock in capstan lathes. If you go to the Hardinge website you should be able to find pictures of 2D collets.

That picture is hard to tell for me. They also look like mill chuck collets....

They look a lot like Swiss Screw Machine Collets.
Would be nice to see if they are threaded on the bottom.
They could be any number of collets, do you have any info on what sizes they are? If they are 1" and under, they are most likely Scew Machine Collets or Tool Holder Collets.
Still just guessing though.

Tough to tell with that photo.

are these small or large, at a first glance they looked like those used by MAXNC but after looking more closely they appear to be larger. Picture is so small but did u buy them?

[rhino]

nah, i didn't buy them. they are too big for my application. plus i haave opted for a 6" three and four chuck. i did find a company that had them, but i forget what they are now, i'll let you know.

[leberen]

dont worry, if they're too big for u to use they're certainly too big for the maxnc... they just looked familiar. sometimes its too easy to buy stuff on ebay.

[dertsap]

Definitely Swiss Screw Machine Collets. check out the Hardinge Tooling website. www.hardinge.com I have no idea as to what size or machine configuration, but definitely Swiss Screw Machine. More than likely an old Nakamura-Tome early 80's. Could also be a Cam style Brown&Sharp Swiss too. Now I miss my Tsugami and Star even more.

What your seeing in the front where the tools are is a Guide Bushing, about 3-4 inches behind it(depending on the Z Axis Stroke) holding the bar stock is the Spindle Collet. The Guide bushing is stationary and so are the tools X and Y are in and out A and B are up and down. The Z is always Positive respectively unless you want to position a tool in front of the Bar Stock without cutting it is Z(-) Negitive. Fun Machines really as all parts are complete with out any secondary operations. Turning, Milling, Cross Drilling at any angle you can imagine. You setup/program/proveout/walk away and check every hour. Holds .0001 all day even in Inconel X750.
