Who wants to make a really big MM?

Ok, not a MM, but in some ways it has some similarities.

... The cutting area is bigger than most shops! :)

That EEW site is to advertise those monsters for sale - they have already sold 45 in various sizes.

I like the "extrusion" (smearing) :)

Looks more like a Gantry Crane than a CNC machine. :)

What on earth do you make with one of these? And after you've made it, how do you move it?

[Gerald D]

Doug, have a look at Milling and extrusion of a concept car (http://www.eew-maschinenbau.com/fileadmin/Dokumente_deutsch/video/automobil_en_2_mov.wmv)

Gerald,

That was so cool. I suppose this means I will have to take the roof off of my garage so I will have enough room for the smaller model. What do they charge an hour to cut those models?

[smreish]

Those car model's you see in the video typically cost anywhere from 25-50K dollars depending on detail of model and final finish required.

A lot of times the CNC will over cut the model by 1", then hand trowel on a machinable wax or clay, then re-cut the model.

So, you have to cut a lot of models to pay for that 3M+ dollar machine!

On the average, people like 3dcutting.com in Canada offer this type of service on a lower scale for a much more reasonable price point.

To answer your question Nils, the industry typically bears about a 300$ per hour run charge plus material on those models - all inclusive.

Sean,

That cut price seems cheap for the cost of the machine.

[servant74]

Keeping them busy would seem to be the point to make $$ at this.

For a MM, what is a reasonable hourly rate if someone wanted cutting done?

Say that they get $300/hr for $300MM machine investment, then that is a
$20K (equivalent if purchasing a put together MM, IMHO) would be about $0.02/hr
if that is the same rate.

[Gerald D]

We run in the $20-$50 per hour range.

Gerald, why such a wide (30$) variable rang ??

Since on this subject, I’d like to read more about this, meaning, you guys doing this as part of your business, how much some of you are charging ?
What are those fees, meaning, drawing & programming as part of those hrs rates or seperat ?
How much $$ /hr for : CAD / hr, then CAM / hr and the machining alone ( the time the beast at works). Surly some charges a single hourly rate for all, that too be interesting to exchange on.
I guess what I’m asking is detail info on how you guys making a living out of this are managing those charges ??
Thanks... Robert ;)

(BTW Gerald, change my post location if you fell this is not a proper location for my questions or you feel it could drift of this thread :eek: )

[Gerald D]

That range is the prices available around Cape Town, not only for us. Some guys are trying for more customers, some include/exclude programming, sandpapering, rough cut, smooth cut, etc., etc.

[servant74]

Sounds like a reasonable range in many markets. Since I don't have one built yet, roughly how much gets cut in an hour (excluding sanding, programming, etc).

Do most cuts get a 'rough cut' or two and a 'finish or smoothing cut'?
Are the rates like were posted including or exclusive of materials?

[Doug_Ford]

That was a fascinating video. Thanks Gerald.

Thats an amazing video.
