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.

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 .
