I know the 16T ATC is over the top for stock X2's so I've started sketching a 3rd Automatic Tool Changer.
It will be the little brother of the 16T.
Smaller, lighter, cheaper and a little different with components that will be X2 work envelope friendly.
Builders will have a choice of 8,9,10,11 or 12 tools depending on how many large tools they want to run.
There won't be any medium sized toolholders, the chucks that I used for them are pretty crappy.
Better off with the bigger 3/8 chucks that fit the large toolholders.
I'll be adding these plans to the 16T DVD-ROM and will be giving free upgrades to the folks that already bought one.
I'll make this little brother in the next couple months but the plans will be done in a couple weeks.

That sounds great. I was already planning to order the first one from you (just for your original changer) but this suits me even better. The 8 tool setup should be plenty for me for a long time.

I do want to get the asammons "monster" conversion done first then add your ATC to it. I'm assuming the 8 tool ATC is also rotary ?

I'll place an order with you soon,

i wonder how hard it would be to modify all this to a x3 mill...

Hey Steve,
should only take me a week or so, actually this weekend and maybe next, to make the CAD drawings.
It'll be rotary just like the 16T just smaller.

Teyber,
The only mod for an X3 would be a shorter swingarm than what I used.
I have 13 inches from the spindle to the column versus about 9 I believe for the X3's.
The 2 things you X3 guys have to work out first is a power drawbar and spindle control.
No ATCing without them.
Wouldn't think it would be too much trouble if you're really set on it,
I would permanently lock the quill and borrow the electronics from an X4.

Hey Hoss, I was just looking at your youtubes right now! I'm learning a lot. It's all great but why another tool changer? I mean you already conquered that. How about something new like incremental sheet metal forming? Or finish that trunion table you talked about in that other video?

Oh this won't take long, I wanted to make one that works for my X2 buddies.
The trunnion is a definite but the "incremental sheet metal forming" is a new one.

Looking forward to seeing the video of that trunion table! I've got a newb question if you don't mind. When you are tapping the holes for this table how come you need a stepper motor with a belt to the spindle? I mean X2's have reverse right?

Nope X2's like most mills aren't reversible.
The stepper drives the spindle in concert with the Z axis to move at the same pitch of whatever thread I was cutting.

I have the Procunier tapping head Hoss....A bit like in your sig I got it for £20 brand new from fleabay a few years back (jammy bugger eh!) I'm paying attention now so get on with it (getting tired of toolchanges but MT3 wont like an ATC! so new machine on the cards soon)

[SScnc]

but MT3 wont like an ATC!

Why would this be ? My 3/4" MT3 collet releases my TTS clones fairly well, I may have to reduce the diameter of my TTS clones just a touch so they will actually drop out yet still seat firmly in the collet. Is this going to be a problem for me with an ATC ?

Morse Taper is a bugger to get it to release......Thats why you get a big hammer with the machine

I'll wait for R8 before I attempt it....Probably also give Hoss some cash for the inside look at the programming etc too :beer:

I may start the Hoss fanclub!

Thats a steal on the Procunier:cheers:
I was looking at one when I was trying to figure a way to tap all the holes on the tooling plate.
MT3 should be OK, LMS's Zbot power drawbar has an MT3 version.
My power drawbar can put almost 1100 pounds of force on the drawbar at 100 psi,
should be able to pop it loose.

Well after a quick search we'll have to add this to the projects list.
Cool stuff.

Glad you plan on trying it! Looking forward to seeing it! I'm wondering if your steppers will have enough torque driving directly like that to push the metal down or if you'll have to gear them down with timing belts in order to be able to do it. I'm also wondering if anyone knows where to get that bit and what it's called?

[Kipper]

A while ago we used stainless discs in an angle grinder for getting dents out....I wonder if it works on friction expanding the metal?

Who's going to try it first

Are you serious? How?

[Kipper]

Are you serious? How?

Hit the dent in the centre with the disc...the metal expands so quick it stays expanded....Never questioned it...just used it.... I think it was "reinvented" a couple of years ago...... Google is your friend

If you read the comments on the youtube page it's done by forming over a male die.

[hoss2006]

Apparently there are 4 methods to the Incremental Forming Process.
Negative die-less forming, also known as single point incremental forming (SPIF).
Positive die-less forming, also known as two point incremental forming (TPIF).
Negative with-die forming and Positive with-die forming.
I found this PDF that explains it.
The cool stuff I linked to before is the SPIF dieless method.
Probably the one I'd try first.
Should be a fun project, after this one of course.
Found another video that shows a cooler Positive-with-die method like the other video.

[pete from TN]

So are you saying that there is a mold or form under the sheet steel and the round ball is just spinning on the sheet metal with a lot of force pushing the steel down over the form using a small offset accounting for the thickness of the finished steel? IS it a heat generating process or is that thing vibrating up and down on the steel? Looks real cool tho and just another kind of amazing process that is afforded to us by the miracle of cnc control.... VERY COOL MAN>>> Hoss if you can make your X2 do that then you truly are a wizard!!!! peace...
