When you have to build your machine in a tent you know you have gone way beyond hobby CNC.

Thankyou Mark for sharing this awesome project with us all.

That there is no hobby build for sure. I like steel builds, but this one has a very serious purpose behind all of this expense and effort. There's some quality design and welding going on under that tent. Maybe this will eventually get moved to a more permanent industrial location.

I suspect that it will be stiff enough for most of us watchers. I wonder what it will weigh when completed. We need a poll for that, and a piece of scrap steel from the build as a prize for the correct guess.

Thanks for posting this build here.

yes... but DIY work

This will eventually get moved to a more permanent industrial location.

yes... it will be moved... or hold out

I wonder what it will weigh when completed

about ~3000kg

When I look at your pictures I can only say - holy crap! that's some awesome piece of gear your building there sir! - very nice!

[rab]

that's a very interesting machine,
what will you make with it ?

[austin.mn]

HOLLY SHNIKIES! That is one heck of a large machine!

What are you planning to cut with that machine?

[LazyMan]

Keep the pics coming! This is just too cool.

[markcomp77]

its for surface treatment of mold (mould) for thermo forming machine (moulding machine)

about ~3000kg

Thanks for your answers Mark. I can only be envious of building something of that scale. 3000 kg = 6613 lb and 13.88 oz = a lot of metal.

I will try asap

Wow.

[fortyonethirty]

Awesome! What is the intended use?

[Splint]

Excellent work gentlemen, I'm looking forward to updates.

[Jesse B]

That thing is truly amazing. Excellent work!

[RomanLini]

I knew it was big... But that picture of bartuss standing INSIDE the machine kinda bumped it from big to BIG...

This si the first thread I've seen of a guy standing inside the CNC machine he was building!

Great thread!

No comments on the CNC drill press?

It looks like the drill press did a fairly good job but it does look like it leaves some chatter marks.

Great job so far.

Hei - may be this is not just a curiosity for the rest of us...

I think every amateur CNC'er dreams of playing with a 5-axes machine, but very rarely
have I seen a working sample here on the zone - the 2-axes rotary head is particularly
difficult to design...

But, here we have a professional 5-axes machine, and we might be able to get more info
on the design. So, would it be possible to scale this monster down to a size that would
be acceptable for an amateur machine? May be a factor of 4, resulting in 857x625x425mm
overall, with travel of 625x375x250 - quite nice for a medium-sized amateur machine!!!
Weight would be about 50Kg (1/64 of the full sized machine...)

May be some of the geniuses here at the zone could come up with a feasible design - I
know that not everything scales nicely: the spindle is probably the most troublesome,
but who knows? Think about it: a real 5-axes amateur CNC router!!!

Great work! Can't wait to see the video and the sound of 7000oz-in stepper motors.

Here is a nice small 5-axis machine. You could fit a dozen of these in this big monster. I think it is big enough to park the car in it and attach a buff to the spindle and have a CNC car polisher

[epineh]

This is a cool build, can't wait to see it in action

I was wondering...with 5 axis tool zero-ing, do you have to zero the tool twice ?
Say if you were machining out something like a cup, once the head assembly rotates 180 deg to the other side (I can't explain it any better, hope someone understands) the tool offset (away from the centre point) will have to be known and allowed for to use different length cutters.

I would imagine you would zero the tool facing one way, then spin the head 180 deg and zero again, then add some kind of offset, or do I have it wrong ?

Cheers.

Russell.
