My new machine - Guess the make!

[didineedthis]

Worth the wait.

Yes mate i would rather wait for 6 months and get what i want as it does look like a solid build

What size have you gone for?.

1200 x 1200 :)

I've been on this forum since April 2020, asked a few daft questions, got my head around what I'm after and have recently collected and set up my new machine.... Maybe you know the chap who made it?..... Goes by the name Jazz something or other.....

Anyhow, after many lengthy emails and conversations discussing needs/wants type of build, this Jazz bloke who also likes to be called Dean has rustled a few part together to produce my first CNC. Feels solid as a rock and weighs more than one too. Me and 3 mates were at our limit lugging this brute into my workshop.

Just like to say a massive thanks to Dean for all the info, the 4 hours I spent with him 'upt North showing me the ropes. Has got me off to a cracking start and he is a top bloke to boot. I'd gladly recommend anyone chatting to Dean to see if he can build something to their needs. Can't see you going wrong really with the knowledge he has.

Anyhow, here are a couple of pics and I even tidied my workshop up all special like.

Very nice machine and shed, but everything looks so clean and sterile, like nothing has been used before. I wish I could keep my place this clean. OK, my CNC is just as clean, but that's in my normal home office/hobby room/electronic workshop, my other machines, like drill, saw and so on is in a hobby workshop, where it is clean to be a workshop, but not as sterile as your place. I like clean work spaces, so I honestly envy you for the cleanliness.

I have in the past worked in mess. You get used to it. My workshop is small, 120² ft. I’ve got lots in there so it needs to be tidy. At the end of each day I whip round and tidy up. Therapeutic! The next day when I go in it’s fresh and tidy..... keeps my mind fresh and tidy!

You can also consider doing what I did.

I would just try to lower it from the castors to the floor and let it rest on some extra wooden blocks. To me it was a big improvement when I did that. It is less dramatic than having to do what you plan to do, but of course, if the floor you have is not stable enough, then you might need to reinforce it, but I would still not bolt the machine to the floor, or to any concrete pads.

I’ve seen your incredible machine and post. I don’t need to move.... as you said, my floor is not solid. That’s the issue.

I just mean that in my experience, moving the machine may be necessary, if for nothing else, for cleaning behind, or when something is dropped which can't be reached otherwise. I think if a machine is bolted it should have enough space around it on all sides. Anyway, the concrete pads idea may be good, but it is a bigger job. I'd still start with the simpler thing first, and would remove the castors and let the machine rest on wooden blocks or a thick wooden plank, like a beam. Maybe that would distribute the forces more than enough and would still give you improvements and stability. As it is now, the actual surface your 400kg machine is resting on is extremely small and all that mass plus the extra force generated by the movements is transferred to the floor through that small surface contact. If you increase the surface which is touching the floor you distribute the forces in a better way. But of course, you will get the best stability of you bolt it to the concrete pads, so if you KNOW you never need to move it, then it is a good idea in my opinion.

The machine isn't sat on castors, it sits on 80mm Dia adjustable machine feet.

Thanks. Looking now on a bigger screen I can see that clearly now.

Fwiw..
Haas machines are all solid bolted to the floor via adjustable anchors.
Part of the included-in-cost installation is very precisely levelling the machine.
To within about 0.02 mm.

Everything flexes, and the modern machine beds or frames wont be straight unless they are mounted perfectly level. +/-.
And if they cut a part of max size, it wont be perfectly flat, straight, and level to within 0.02 mm guaranteed (which is not so accurate in fact).

A VM6 will cut a huge mold to within 0.02 mm, volumetric, mostly much better than 0.01 mm, no problem.
Linear scales, a 13.000€ option, wont make it any more accurate, but it will insure the client gets what they paid for.

My client was extremely happy, with the VM6 with scales, replacing a machine, chiron, that had been 4x more expensive in it´s time.
Making very very intricate 3d molds in steel, maybe 3000 kg each, that really needed to be accurate.

The molds cost about 250.000 € each, and need to have errors of no less than 0.04 mm, otherwise it shows in the final product.
A truck bumper might need upto 8 pieces with 8 molds.

I´m on the ethical edge with disclosure.
The general parameters above are known to anyone making molds industrially.
It´s not right to go into any more details -- most of which I don´t even know.

0.02 mm volumetrically is hard to do.
On a single axis, a short distance, it is trivial.
Anyone local cutting keys for locks does that.

The difference is about ...
2x-3x the distance, 3x, so 3x pwr 3 = 27,
times 3 axes, 81 times less rigid/accurate.

...which confirms my conclusions in this thread about permanently keeping a CNC on castors. Bolting may be necessary for that machine, and I am sure it is, but even for hobby machines, a solid base is necessary, even if not bolted, and that can not be provided if the machine is resting on rubber, silicon, or plastic wheels. They simply can never provide enough stability for the use case.

Oh yeah, one up manship! Mine is a mere 600x900. Dean can I order a 1201x1201?!

Here are a couple more bits and bobs I’ve racked up in the last week. Still honing skills but learning all the time. Even went barmy and spent £20 on a proper make bit instead of my Banggood specials! Now that I do not want to break!
