Videos like these are kinda of exciting, it is sort of like a glimpse through a brand new telescope for the first time.

It was interesting to see you using WD40 to machine aluminum. I hadn't realized that has become so popular outside the US.

I used it before reconditioning the big mill for the flood coolant mainly because it had great comments here in the zone, it's not easy to find in Spain too but you know, i prefer paying a little more for something that works than trying to find a cheaper solution than in the end, it comes more expensive.

Katran, perhaps you should take a look at a misting coolant system, it makes less mess than flood and surely you'll be able to push harder (flame2)

Hi Katran,
as a first i really admire how your workshop is super clean!
I have a few questions related to your gorgeous milling machine.

0) which is is the max size of the workpiece which can be hosted on such mill ?
1) which is the grade of the ballscrew you used ?
2) which is the grade of the THK linear guides you used ?
3) you mention that you used isel ballscrew. I presume that isel is the brand of the ballscrew, right ?
4) do you think that filling the aluminium extrusion with epoxy granite would improve machine stability/stifness ?
5) do you plan to share drawings of such milling machine, for example on grabcad ?

Best regards,
Andrea

Thanks .

0. max workpiece 450mm x 260mm x 250mm
1. Rolled ballscrew ISEL 2505 precision class C7 on Y and Z axis , precision
ground Leadscrew International 3210 on X axis .
2.THK SHS30 linear caged ball ( low noise , 4 way equal load )
3. ISEL is a german brand of ballscrews . True C7 , not like chinese crap
found on ebay ... I will upgrade later to G-Ten brand ( rolled C5 ) .
4. Yes , it would ... probably in the future I will do that ...
5. give me a message at "[email protected]" and I will send the archive
( neutral 3D / 3dm,step,iges ) . Files will be packed with WinRar .

happy ?

cheers

Hi Katran,
thanks for your availability, I've sent you an e-mail a few min ago

I noticed that you choose a "low noise" guide. Does "low noise" guides really makes less noise than "usual" guides ?

Moreover, I've got a question related to ballscrew accuracy (maybe it could be better to open a separate thread??)
You plan to upgrade from C7 to C5 ballscrews. Will such upgrade provide a significant improvement in the quality of machined pieces (accuracy of machined pieces). I do not have much experience, but i presume that vibrations of the spindle plays an important role in machining accuracy. Do you know is someone measured how accuracy of a machined pieces is a function of X,Y and Z ballscrews grade ? I think it could be an interesting test.

Thanks for sharing info about your machine.
Andrea

SHS series rails from THK really make a lot less noise ... balls are caged
in some sort of plastic chain . It realy makes a difference ...

Upgrading ballscrews is a "must" . At the moment , machine error is
less than a thounsand of an inch ( 0.02mm ) , but with C5 ballscrews I
hope to get 0.01mm .

Vibration of the spindle is a big problem . That's why I bought a big ass
Colombo ( 10HP , 380V/3ph , 18,000rpm ) ...

Check your mail ... file ( rar archive ) sent .

This is interesting as I didn't realize that WD 40 has such a wide distribution. It is actually a bit of a surprise that WD 40 works so well for machining aluminum. It is one of those mystery fluids that does so many things but none of them extremely well.

I used it before reconditioning the big mill for the flood coolant mainly because it had great comments here in the zone, it's not easy to find in Spain too but you know, i prefer paying a little more for something that works than trying to find a cheaper solution than in the end, it comes more expensive.

I could not live without WD40 it is magic stuff so many uses.

Great stuff, well done you have inspire me again as myy project stalled many months ago (despite having acquired servos, drivers SHS rails and some of the extrusion) - my confidence that I could build a machine that was accurate and chatter-free enough as I had in mind (also aiming for .5 ) was in question. Having seen this project I am going to start back up :-)

If you are still willing to send files, I'd also love a set (I think you use Rhino? I have this and SW available anyway).

Thanks again for the inspiration!

Sure ... give me a mail adress and I will send the files .

Hello


Nice project there.
Can you tell me whats the X axis shaft diameter in the first picture in your last post?
And what's the workable area of that router.



Greetings.

Working envelope of the router : 920mm x 650mm x 200mm with 140mm clearance under the gantry

I do not understand : wich X axis ?

Thank you for the fast answer.


Im talking about the longest axis.

Im doing a 600x600x200 cnc. Do you think 16mm diameter shaft will handle this measures?

I don't use shafts ... only linear rails ( THK ) . Depends on what you want to
machine ... for wood and plastic , 20mm dia shaft would be o.k ...but for
aluminum , you need linear rails ( profiled ) .

Awesome build!

Sorry man , I don't get it ...

[airkicker]

Katran, I`m amazed about your cnc Mill. Please, could you tell me, What servos do you use in this progect(kW-? torgue Nm -? Price -? Model -?), servodrivers and controller?

May be you could make the photo of your electical box of the mill?
I`ve bought the milling machine, and would like to count everything to convertion.

Till today, I do not know how find the right power, torgue servo do i need to my mill?.......

Sorry for my English.

All I can say is AWESOME JOB! Beautifully done!
