New machine build - big 5 axis

[Bartuss1]

My previous 5 axis machining made ​​into steel.
more tests big 5 axis on saturday

big.

[DonFrambach]

what are you making out of that huge stack of mdf?

[Bartuss1]

Hoof trimming the thermoforming plastic

That's a nice table! I eventually want to build my own but for now im working with a EZ CNC table, I like it alot!

[Bartuss1]

we did rebuilding Z axis - ballscrew, 2xpiston fi 100x2000mm's
reduced the cross-section with 500x500 to 300x300 mm's

[aarggh]

The effect of momentum on this must be enormous surely?

cheers,

I wrote an ebook about this machine



The book is a lot of pictures, drawings with dimensions and descriptions.
And the whole history of the machine

cost about $ 20

here you buy

This moment is small
I wrote the ebook for some interesting observations.

I would say the heck with the machine that size, I want a space that large, then I could fill it will all kinds of 'toys'!

Hi Bartosz,

I bought Your e-book about giant 5 axis machine and have few more questions:

1. You vaguely explained most important thing for me - about leveling long ( all axis are long in this monster) axis, mounting rails... You mentioned that grinding would be impossible or astronomically costly, so what decision did You make ? Did You use self leveling epoxy or shims ? Because I cannot imagine how to weld 9 meters long structure with 0,2mm tolerance.Same question for Y and Z axis if its different technique.

2. Did You use any measuring equipment to check straightness, perpendicularity,parallelism of axis ? how to check parallelism between axis 5 meters distance apart ?

3. "therefore lower cup ring is slidable in the vertical axis in the range of 2-3mm".
Can You explaine more, or give some pictures how did You make slidable fastening to Hiwin trolley, or maybe I completely misunderstood the construction.

With all due respect to Your work, I recommend to give e-book to edit to someone who is proficient in English, because there was plenty of places I didn't understand what You mean. (Not one or two places, but 10,20 or more...) Writing in forum is OK, but then You ask money, it's a bit different.

Greeting from neighbourhood, Lithuania

Straightness of - pads with feeler
plane of - water pipe device - two tube, garden hose and water
angles - the diagonal measurement of the milling and setting the gate on the drive rack gear

the lower ring isn't connected with the cup axis, but it is tightly folded.
