They look like the machines that made my ones

anyways... lets see some vids of them in action... red hot chips flying everywhere

And they have a bed big enough to strap an operator to, and yell "I'm gonna scrap you for doing all that damage to the mill yesterday!"

Very Nice, I'm not jealous because I can't envision ever needing or using one. I can appreciate the technical complexity.

The boys from Brighton have a song that covers those, "Fat Bottom Girls" yep they do make the world go round - so I'm told.

Hell I get excited over a 40" X 20" X 20". Well good on ya, someone has to buy them. So what do you all make - mostly? Wind Turbine Parts? Fusion collider parts for Alien Spaceships? Shirley not replacement hip joints for elephants! (I had to borrow an Ox word!)

Can't imagine the power bill - I would dim lights for 10 miles - TVA would have ta open up the gates on the Turbines full tilt!

"Can't imagine the power bill - I would dim lights for 10 miles - TVA would have ta open up the gates on the Turbines full tilt!"

Makes me wonder what you been doing with thet Litz......TVA just announced a 20% rate hike to go into place in October. How many amps you pullin?

I meant on the Fat Girls. My Little Slim Trim Litz Honey sips juice at 30 amps at the most. Highest bill was $140.00 with compressor, lights, A/C and Brad Paisley playin on the Stereo and the VMC running full tilt.

Naw, if I had a big honkin machine like that Toyoda they would have to lay in a new feeder line, otherwise the neighbors A/C would run backwards. I'm on a 25KVA transformer and the next move for the bigger shop is getting the three phase run. just gotta find out who I have to press to get the USDA funds (grant) to lay in the line.

What an amazing piece of gear.

Like Mitty I can get plenty excited about a VF-3 so this is just over the top.

Thanks for taking time to post the epics up, maybe a few more when you can.

The electric bill is no problem, the chips and scrap will more than pay for that.

But imagine how many pounds of aluminum it will take to feed it and keep it busy for a month! Then X3!

psychomill - How does it feel to sign the contract for a purchase like that - is it just another number, or does it make you worry about the outcome?

Psychomill's company turned a measly $450,000,000 profit in the first quarter of 08, so he's probably more concerned about what these monsters are gonna produce, and how to do it, than about cost of the machines themselves....

Cum'on guys - it's only 40 horse eh?

Is that all? Thats only 1.8 Billion annual and to think they say the economy is broke! Are they foreign owned?

They list
Spindle Drive Motor(15min./cont. rating) 40/29.5 HP (30/22 kW)
Spindle Drive Motor(optional) 49.5/40 HP (37/30 kW)
Spindle Drive Motor(optional) 40/33.5 HP (30/25 kW)


Is yours the 49.5/40?



105,800 lbs, just in raw materials it costs about as much as most of us would dream to put on a "little" machine

Yep slow in the wide open,but devilish fast when your 12" deep.
Safe Z before XY.(ha?)
you can test the meddle of 40HP with a 6"facemill ,50 taper, put the amp gage at 100 percent iffin you desire,eh?
It always seem to suck gettin such a virgin beauty dirty for the first time.
Askin the price is kinda like asking a Farmer how many cows he's got.
Or how much does your wife weigh?
At the risk of being told to search,what is your end product pshco mill?

Showing it with its clothes off really is porn! I had always wondered how the really big machines were delivered. Were all the guts delivered in one pre-assembled chunk like that? And how many lorry loads did the machine in the first post come in?

Cheers.

It always feels good ... just wish it were all mine! I've been part of many projects much much larger than this though in the past so this isn't the largest dollar amount for machines on a single purchase for me... but none the less...

$450M in the first quarter eh Joe? I guess it is a bit slow... ... considering I believe were toying with the 40 billion mark in assets. Of course, the market is down everywhere including overseas.. it may take more effort.

This has always been my belief and personal policy regardless of the size of shop I own or work for. I don't care nor lose sleep about the costs up front, I only care about what it's going to make me which takes care of the cost and burden on its own. The size of the shop doesn't matter either, this has relativity. But I'm opening up a can of worms here. Let's not go down this road... its a whole different thread.

The spindle goes like this:

40/29.5 HP (30/22 kW) is a 6k spindle.
49.5/40 HP (37/30 kW) is a Hi-Power 6k spindle.
40/33.5 HP (30/25 kW) is the 15k spindle.

We have the 15k spindle.

Isn't that standard operations? And I was off on a couple things. The max feed is 1181 ipm... the rapids are at 1653 IPM although I've seen this number at different rates for some reason. But its 1653 according the machine books. The acceleration is at .3g which I think it could be better even at this size/config. At least .4 but any-hooo....

How many lorry loads??? How about 6 of them for each machine. And yes, a lot of the "guts" is already on. But the floor is still littered with parts and boxes and crates, etc, etc.. The machines I have coming in next month will take 9 trucks each from what I hear.

Psychomill just curious what the lead time was on your machine?

Does anyone do DCG machines of that size? I would have thought that rapidly accelerating a moving colum that large entirely driven at its base would be rather tricky - especially if it's cutting with the spindle at the top.

Nine trucks per machine - that is big iron! I hope they are far enough apart for mutual gravitational attraction not to affect their accuracy

Now I'm very curious as to what those next machines are, still Toyoda, or another brand?

The lead time on these particular machines was real short. When we we're looking for this capacity, it just so happened that Toyoda had 4 of them in build. We took 3 of them right away. I think we're only 3 months into it right now .. maybe 4. The "short lead" though also is the reason why the machines aren't totally to our specs. The 330 tool hive won't be in until October so they came with the 60 and 120s (which is how they were being built in Japan). Machines also showed up with 6k spindles and one machine has the wrong table type on it. This part of it was all a surprise when it showed up so I bitched at Toyoda about it. None of them ever told us. Anyway, there will be some field swapping going on.... If I had to guess, I'd say these machines are in the 8 month plus range for a build to spec. Toyoda has some capacity and they don't sell nearly as many machines as others so build time may not be that long when compared to others in this envelope.

DCG (which is a name copyright/patent of Mori Seiki) machines are built by several machine builders. Some of them by design, some by "accident" if you will. One of the big reasons the acceleration drops off on machines this size is the column weight and torque or leverage when in motion with the latter being the biggest problem. Some of the innovations because of this is also moving to a "stepped" or staggered guideways for the X axis. The intent on DCG is to be as centered as possible. With the strokes and windows at this size, "it's as best as its going to be" idea. We'll see....

The next machines coming in next month is.....

DCG?

Is that where the table and the ram both have X screws? Like those slot card machines from Mazak and Mori?

It stands for Driven at the Centre of Gravity - and basically involves putting two screws on either side of the mass you're wanting to accelerate so that you can get linear acceleration without any torque skewing due to the centre of gravity being a fair distance from the screw. They have a vey nice flash marketeering explanation of it on their Japanese site: http://www.moriseiki.com/english/index.html - click on the 'Driven at the Centre of Gravity" bit.

The reason I asked about it was because on a machine the size of the ones psychomill has, I would guess it would really help smoothly accelerating the column - imagine accelarating a jelly (jello ??) on a plate by moving the just plate vs moving the plate and pushing the top at the same speed.

Yeah, sorry - I couldn't think of a more generic name - balanced/twin-screw drive I suppose would fit. There must be a hell of a lot of moving mass in the columns on those big big girls - bring on the vids
