Anyone selling buttress thread to 5/8-11" adapters ?
So you can use CAT40 tooling on a manual Deckel ? Could get some threaded rod from Deckeldapter guy, and make my own...but I vaguely recall someone somewhere offering the completed deal, but I wasn't paying attention at the time. For that matter would be nice to buy buttress to M16 adapters to use BT40 tooling too.

Singer also has the opposite converter for tooling...That is to say a ring ID threaded to fit the 20mm Buttress and with the OD turned to take the grippers from a CNC spindle.
I have a number of these and they work fine...allows the standard 40 Deckel collet to be run in your CNC machine.
Or a standard manual arbor for horizontal work to run in your FP-NC...
What i use them most for is holding my buttress threaded Deckel test arbor in the CNC machine to set the head for angle or true to an axis etc....

Well i like the ability to use the horizontal arbors and not have to stock duplicates of a tool i would rarely use on the CNC. And of course the test mandrel as stated before.

Milacron, the part you seek is called an Anzugsbolzen apparently.
Here's a current ebay item : 120562976263
For posterity's sake, the price is € 7.20

There are several companies that make S20 to M16 adapters but I haven't found one that makes S20 to 5/8NC ones. I've spent a fair amount of time looking but no luck.
For M16 versions, you could try Haimer USA:
Haimer GmbH - Pull Stud
(last one on page)
there's also Schunk:
There's also KFH, or just get them from Singer.
Spannzangenfutter, Collet chuck, SK40 - KFH - Hersteller von Fräserspannwerkzeugen

Uh...Chris....that's not what we're talking about... those are pull studs. What we are talking about would look like below...

or... you could try Haimer USA:
Haimer GmbH - Pull Stud
LAST one on page. (Pull Stud with saw thread S 20 x 2) Not the first.
Regardless, this afternoon I ordered aprox 32" of threaded S20 rod from Mr. Deckeldapter and will just make my own. A slight cringer as I just got in an order from Singer today and could have got a few of these for essentially free shipping if I had the foresight to ask about these a few weeks ago ! But it's ok since I'd really rather have S20 to 5/8-11" anyway...got more CAT holders than BT.

The ones Singer has are really nice, too bad you missed including it with your order...
His ebay shop has two versions, one is more expensive and has the buttress portion with ground threads.
I've seen at least 5 versions of the same thing from different manufacturers, with minor variations so you'd think someone would make an inch version.
FWIW, Singer's I liked the most as they have a broached hex in both ends and the hardened & ground thread makes for smooth insertion.
Schunk's catalog drawing looks identical to the Singer part, maybe that's his source?

Other versions only have a screwdriver slot in one end or a single wrench flat for tightening so the internal hex is nice.
Online prices vary a lot, Singer's cheap version is a bit over 7 euro each, Amazon.de is 14 Euro:
Anzugsbolzen Deckel SK40-M16 S20x2 GSW: Amazon.de: Baumarkt
12 Euros here: KWT-Tools - Anzugsbolzen DIN 2080 S20 x 2 / M 16 401.20.16.S
to the sphincter clenching 16 euros each in Holland:
G057 S20x2 - Budget Tools Web Shop
Budget tools my ass.
blah, blah, blah... anyway, if anyone with a cnc lathe wants to make some I've got a Solidworks model of the stud in either 5/8NC or M16 flavor. Free for the asking.

Seems that you will most likely be finish machining your adapters with one of your CNC machines & then have to fiddle around getting the threaded rod set up for concentricity.
The great attraction of a CNC lathe to me is fast/easy/repeatable threading........or have I been led up the garden path ?

Mr Milacron just bought out the entire global supply of S20 threaded rod.
Guess I'll have to make some more someday.

Amazing - this buttress thread was the first thread I ever did on my 9x20 (Correction the first thread I ever did) - still got some stock sitting on the shelf.
Now if I had a CNC......
Maybe Milacron doesn't have a 9x20 lathe and his are all too big.

Those threads would run slow enough to use local cutting oil applied by a brush.
Run those studs out of 4142 pre hard material. Plenty strong and will finish like glass if you get it right....about 300 SFPM for turning and thread at about 800 RPM......

Lots of ways to skin this cat. Grind up a proper threading tool and bang 'em out on that snazzy Schaublin you've got. Grind up a tool for a boring head a threadmill 'em on one of your CNCs (doubt you have a threadmill with the buttress profile).

Sounds like the same old story, so many small projects and no time to do them. You dont get paid to make the things you use. I think of that everytime I buy a soft jaw that I should be making them myself but I never seem to come up the the time to do it. I did buy some material to make several sets a few months ago. But then I got busy and havnt had the time to program the machine. Now that I think of it I believe I did use that material for something else after all....
Well I will get around to it soon enough, after I install the air dryer, build a rack for the new collets, make storage for the ring gages, make a rack for the allen wrenches, organize the file cabinet, get someone to clean the cat poop off of the front stoop, wash the windows and before I forget program and run some parts for my customers. Nothing to it, I should have those vise jaws made before lunch.
Good luck Don...
