I have a new toy, an Abene mill, and it came with a collet holder
attached, but no collets. The holder is an INT 40 (or CAT 40) taper,
but I can't figure out what collets it will hold - here are some
measurements and data in case anyone can provide some guidance:

Markings: LOFAB 3035

diameter of hole in screw on cover 1.511 inches
diameter at front of taper 1.60 inches
taper depth 2.90 inches
whatever collet it uses will snap into the screw on cover, but there
is no eccentric like one sees on some Erickson type holders

any suggestions as to what else to measure to provide some idea?? It's
not erickson, at least not any of the sizes I could find to try out

thanks for any help

Sounds like it might be a C5 collet. Don't have my drawing handy, but
if it is, the taper is a Jarno taper. I am in the process of making an
adaptor for my old Atlas, since someone gave me a full set of the
collets.

Thanks, but --- it;s most assuredly not a C5 - thie C5 is pulled by a
drawbar, wheras this collet holder has no threads at the base of the
bore, and anyway, just for grins I tired a C5 collet and it's very
much wrong - this is a single long taper, not a short taper like the
C5.

Not sure what you mean by an eccentric, unless you're talking about the
cam on one of the quick change systems. That doesn't usually work on
the collet, though.

I've got a TG100 holder in front of me and it's smaller, so if you've
got a TG holder it's probably a TG150.

I think that you are thinking of the 5C collets, commonly used
in lathe spindles and in spin indexers. I suspect that the C5 is quite
different, and may be what I have a few of in a 40 NTMB adaptor. I got
mine at Cabin Fever a few years ago -- and the collets which I have are
mostly uncomfortable sizes. :-)

Enjoy,

Collet nosepieces like the ones for the Erickson ER series
collets have an eccentric lip which hooks under a groove in the maximum
diameter point of the collets. This eccentric lip allows the collet to
be hooked under it and tilted into the nosepiece, and when you loosen
the nosepiece, it draws the collet out enough so that you don't need to
tap on the back of the workpiece to release it -- unlike the collets
which came with my old Unimat SL-1000 all those years ago.

Enjoy,
DoN.

Universal engineering made an accupro collet that looks like a tg series
collet. It could be that series.

John

well, from that page, it seems that it might possibly be a Balas
FlexiGrip series C80 collet - now the question is, where can I get
one to confirm, or is there some other way to confirm?

How about osting a picture or two in the Dropbox or on your web pages?

If it's not needed in a rush, watch ebay. Buy one to confirm.
Otherwise call Hardinge workholding department. They may have some not
listed in catalogs or may be able to make them.
Is the collet holder removable? If the collets are hard to find or expensive
maybe try a holder for a more common series collet.

I googled "abene mill" and found this page:
http://www.plastikosmd.com/AbeneMill.htm
If this is the same mill maybe the owner of it would be interested in
helping you.

Thanks, Don. The TG collets have the same self-extracting feature, but
they just snap in to the cap. It is handy. Wish my router had the
same - I hate banging on the sides of the bits to get them to release.

Going back to the start of the thread, I verified my memory that
this is a 40-taper adaptor, so yes, it is removable. There are a lot of
such collet holders in 40 taper. I use some of them on my Nichols
horizontal mill.

Good Luck,
DoN.
