Holy S#!t gotta pic of that thing?

+1 to that

 

Bet you don't have the guy who worked for Domino's last week running that thing!!

 

Does the operator have a telescope to see if the thing broke a cutter 200' away?!!?

I haven't been able to find a picture of it.

Its an SNK, but they don't even show a machine like it on the SNK webpage.

When the south gantry is ruffing wing skins,

it take 2 guys with push brooms to keep the chips out of the way.

gcode,

 

Inquiring minds just have to ask. What kind of rapid feedrate does something that big have?

Is it measured in M.P.H.?

I have a feeling no matter how fast the rapids are, it will still look slow

It rapids at 600 IPM for the X and Y axis,

400 for the Z. The A and b rapid a 240 dpm,

That looks pretty slow on sometime that big,

but there is a whole lot of iron moving around out there.

I usually do all my 5 axis positioning as a

400ipm curv5X toolpath. That way I always know exactly where the tool is.

I'm an hour away.......Be there soon with my digital camera!

I found a picture of the machine while it was

being built. It took about 14 months to build.

I've put a zipped JPG named 5X gantry.zip

in the All_pictures folder on the FTP

Seriously, Haas has some serious issues with this pull stud dilema. I had no idea that so many people had this same problem. I was gonna post the picture of the pull stud.I forgot the Haas tech guy took it to be Rockwell tested.

There was talk about having an Open House

this spring, but its summer now and it never happened. I was looking forward to inviting

some of the local forum.

You guys are making me nervous about the pull studs.

That thing aint normal thats huge, any one using any bigger machines?

 

Thanks for letting me see it.

 

How long does it take to process a scallop path on a wing say 100 feet long and 15 feet wide

[cadcamjim]

HOLY CRAP Gcode.

 

That wouldn't even fit in our building.

All the jobs I have cut in the last couple years would fit on that at one time :-)

[robk]

Please post the picture in this thread. I don't have access to the ftp, and I need to see this thing.

From the perspective of that picture, you are only seeing about 2/3 of the table. There is another 70 feet of table behind the guy taking the picture.

 

We run Boing C-17 wing skins on the high speed gantry. There are 8 different parts, but the biggest starts out as a piece of stock 110 feet by 20 feet by 1.25 thick. It was all programmed

with Mastercam and Predator VCNC. I wasn't involved in that project, but I've done quite a bit titanium work on the high torque end of this machine.

I don't think Dennis used any scallop toolpaths,

but there were a bunch of curv5X toolpaths.

They had to buy him a new Xeon workstation to get the job done.

I was only throwin out a number crunching path, thats amazing. That i hope is the biggest of your machines oh any idea about weight????Thats gotta be heavy, you guys got 20 feet of concrete under that? How about tolerance whats the accuracy over 250 feet. I gotta see it, some day I will.

[G Caputo]

110 foot long piece of material? Holy crap! The questions going thru my mind... I'll just say that is IMPRESSIVE ! Thanks for sharing gcode

Rob,

Check your email.

I have no clue how much it weighs, but they did

pour a 30 foot slab of concrete for a foundation.

The longest part we've run is 110 feet and we

held +/-.010 tolerances on that. The biggest problem we have is expansion and contraction

of the machine and workpiece due to temperature

changes. They are talking about enclosing it

in an air condintioned room to help with that.

First article prove outs are VERY STRESSFUL

[robk]

Thanks Gcode. That is awesome

You sure Jimmy Hoffa ain't burried under that thing ?

We had two pull studs in 1 week break on us. They were thru spindle coolant ones, but the actually broke and the end of the threads. We came to the conclusion that our custom wrenches we made were a little too beefy and we were actually tightening the pullstuds too tight. We cut down the handles on our wrenches and haven't had a problem since.

Acramil in City of Industry did that with one of their 120' machines. Said it works well for keeping things as they should be. They had a guy with a broom and another guy with a hose spraying the chips off the part. They kept the coolant tank temp regulated as well. When you gotta hold any kind of tolerance on big parts you gotta keep things stable else you'll be out $50-$100k in a heartbeat. The thermal expansion on Aluminum is 23.6 x 10^-6/ºC, in.

We made our own pull studs and haven't had a problem yet.

Made them from 4150 pht for our 40 taper.

And fortunately we do not have a Haas.

[jeff]

WOW!

What a machine!!!

I would hate to be the one to have to level that monster!
