    That's a pretty good verbal illustration!

    Keep in mind twin ballscrews doesn't necesarily mean DCG or any configuration of that nature. The key object for DCG is the "CG" part... Center of Gravity. Basically, the machine is designed in such a way that the "mass in motion" is balanced over its footprint, leverages, fulcrums, etc. There are twin screw machines that are not built to a "C of G" concept. Twin screw machines are not new, they've been around before. The collective assembly around the total design/thought process is what's "new"....

    Yeah, sorry - I didn't mean to oversimplify it down to just the twin screws!

    It is very clever stuff IMHO - you can probably build just about any design with enough iron and enough HP to move it all, but if if you don't waste iron fighting nature (gravity, inertia etc) you have more iron left to fight the cutting forces.

    This one is 155k sq ft.

    Anyway, been busy as hell here and still a ways to go. Got some more shots for you all....

    The tombstones is a quick throw together to get going. The actual ones are a little bigger than this one in the pic (with my youngest boy sitting on it). The chips are obviously a bit of a problem. I can cut chips faster than the machine can get rid of it.... but Toyoda is working on this issue.... All three machines are up...

    Next week.... More machines showing up (not Toyoda)... that will be another story...

    Oh man, looks like my auger prediction is coming true in the worst possible fashion! Have you had any major chip jams yet?

    New building looks great, let's see some parts!

    Wow!
    What a nice looking machine(s) !
    Lucky to have a "helper" too in there. Can he shovel chips too?

    Speaking of running hard, and shoveling chips....
    What ever became of D ( originally Danny Tuna?) who was going to run some huge jobs in 7075, with a few million lbs of chips??
    How did that work out?
    Inquiring minds want to know.

    D is here. I/he hasn't had time to reply lately but I keep an eye on the board while programming .
    Those parts have been running for a few months now, got three machines running them. I would really like to post some pic's for you guys but if the wrong person sees them we will get shut-down. CHIPS is a bad word right now. The guys were getting there xmass bonus account really built up untill the last check I got was 34 cents a LB.. I really want to figure out a way to store them also, but how/where do you store 30,000 Lb's a week?

    psychomill; those are some sweet looking girls ya got there,do they perform as well as predicted? Whats the spindle HP? Are they dual ballscrew? Sorry for all the questions didn't read the whole post.

    D, good to hear from you again! At the rate you're making chips, it may be worth contacting Kurt (yes, the vise maker) about one of their "Chipmunk" chip compactors. It will make storing those chips a lot easier, and depending on how much you're able to store, the difference in chip price between right now and 8 months from now, may very well pay for the machine. Hell, just the coolant recovery from those 3 machines will probably pay for the Chipmunk!

    Here's a nifty story of a guy who was running into a similar problem:

    Thank- You Joe, Have a call into Kurt for a salesperson to call. Just waiting to get one of those things in here to give it a try. That will sure make the old puck machines obsolete if it works as good as it looks. Theres an old wharehouse for lease down the street that looks like a perfect place to store alumnums till it goes up. If it goes down the guy that owns the building will have a big mess to clear out

    There's coolant. That was after an hour of cleaning it out and it took another hour.

    Joe, you and I talked about the augers before and yep, they're a problem. Seems someone didn't quite calculate the MRR of the machine cutting to machine removal. Factory is working on it....
    As far as for taking a look... you just need to get your lazy ass down here and take a gander. The "e" machines start coming in next week dude....

    feedrateoveridemacrowhennobodyslookin'
    I've seen some of these....

    As far as for hanging onto chips... no can do. I couldn't afford the amount of floor space it would take to store in a week... even with a puck machine. Got the same problem as D

    As far as the machine info.... It's only a 40 HP spindle which is a downer. But considering the chip removal problem, it's a good thing it doesn't have any more for right now. The machine is a twin ball screw machine. Performance wise, it's early yet but so far, looking real good other than the low HP. Accuracies are right there and good rigidity (so far). We're just getting them up so better info is still down the road. The 308 tool magazines will be in sometime around the next couple weeks.

    Biggest headache right now is with the new control. TMU and JTEKT are busting their balls trying to get it all straightened out but it appears that I'm effectively the Beta tester for this platform. I don't mind it and I knew it getting these things... but it costs time and that's no good.

    WOW! 30k lbs a week. When I heard that I was wondering if one of Kurts could keep up with that, but they claim the machine can process 1200lbs/hr. It would be neat if they had smaller units and you could just park it right under the chip conveyor. Maybe they do?

    There are other companies that make smaller units where you could park it under a conveyor provided you had high dump conveyor. I've put together many systems where the machine conveyor dumped onto another conveyor that fed a puck machine directly. You can line up a number of spindles that way. Even did one system that after the puck machine did its thing, it dropped off the pucks into a large bin outside of the shop for pick-up.

    Psycho, I hope your chip wash down works better than the one on our vertical...if the coolant level is not perfect, the TSC won't work along with the chip wash...minor detail, but can be a real PIA. The logic and sensor hardware really doesn't make sense, but for us it's fine...I don't think it work too well with a serious amount of aluminum chips though.

    Are you getting better than 6 cuin/min/HP with these? Lets see, that's about 3 cubic yards an hour of chips...hope you have at least a wringer if not a pucker! I'm not sure those augers will really cut it...they just never seem to move enough material - maybe a couple of belt conveyors in there would do the trick.

    Congrats on the new toys...looking forward to the pics of the next ones!
