Hi guys,

Just curious. 270+ pages on Epoxy Granite. Too much to read and to be honest, someone can use the info there for their PhD thesis or something. Anyone actually made a working table (Nevermind, happened to browse thru page 150+ and saw the results).

There is a sticky on the subject, missed that one?

Hello mate,

the Germans do the same in 5 pages and with nice results,
They are my neighbours, i`m from the Netherlands.

They don`t talk much, but say a lot.
This, we dont see that often, the inverse off politics.
:boxing: I regret that the shaming smiley isn`t there any more, was nice.

Regards,

Here the machine,

Hi Sven,

I actually saw the sticky but so much info I was dumbfounded. I however realised there is actually a result done by someone here somewhere on page 150+.

Hi Roy,

The picture you attached is it taken from the website or it it your work? Interesting. Really like the dovetail ways. I wanted to do something similar for a mini mill table but a guy in a local institution here who runs a machine shop in the school never did cut the metal for me (probably busy with students) so the project was shelved.

The table size and travels look abit small.

Hi Alex,

here are some links to nice machines on the cncecke, not all epoxy granite.

You must log in or registrate

And last a picture off a machine i would love to make if there was budget off around 1500 euro.

Hi Roy,

Tried to register. But not sure whether I manage to register. Still ahven
t receive any email from them. And plus its in german. Can't understand.

Alex

[veteq]

ach so,

registreren is registrate
login is login,

maybe the mail will come tomorrow, otherwise try again.

regards,

roy

[alexccmeister]

I understood those words but after registering, nada! I don't understand the words after that. Nothing recognisable I am afraid. Still no mail. It is possible to attach the pictures to this thread? Sorry for the trouble Roy.

I was able to register. A few pix on my cnccookbook blog so you can see what they're doing:

Search "German Epoxy Granite".

It's very nice work!

Cheers,

BW

[alexccmeister]

Wow! Just wow! Thanks Bob. And thanks for the ingredient

That is similar to what I wanted to do. My only problem is getting precision cut metal pieces done. Can I get that kind of cut surface with an X2? I have all the stuff like steel reinforcement, epoxy, stone, quartz and etc minus the steel inserts. Can't wait to do this project. Now I just have to find the extra dough and time.

here guys,

if i have some more time i will show some different machines.

regards,

get your translating right

No vacuum or vibration, just get the mixing order right. (trial and error)

30% Basaltsplitt 2-4 mm (links), 30% Fugensand 0-2 mm (mitte), 30% Quartzsand 0,1-0,4 mm (rechts) und 10% Epoxyharz L und harter L von R&G.DE

Put the **** in the mould and compress by hand a little bit (piece off wood)

Note that there are lots of different formulations for E/G. You'll want to try some experiments before committing to any particular mixture. Availability of local aggregate materials will be a factor too.

I have used E/G to fill my mill base and partially fill the column in order to increase dampening and rigidity. It was very easy to do and those components are now significantly more "dead" if you ring them with a piece of metal.

Here is the home page for my CNC conversion:

http://www.cnccookbook.com/CCMillCNCHome.html

The E/G work is a link off that page, see the list at the top.

As for whether you can produce surfaces as shown, I don't know why flycut pieces on your mill wouldn't suffice for the same sort of metal inserts. Hoss gets a fine finish on his Sieg mill. There are other interesting alternatives as well. For example 1-2-3 blocks are cheap and fairly precision, and they have threaded holes. You could contrive to use them at similar places to where this German has metal mounting plates.

Hi Bib,

Thanks. I just need to sturdy up my mill abit. I am getting some unwanted vibrations. Especially from the Z axis. And my Z axis cnc kit isn't helping either. Its moving about too much if there is a large load acting on the spindle. This is mainly due to me drilling an ocersize hole where the cncfusion kit is seated on the dovetail. Very annoying. Due to his as well, I am getting alot of backlash on my Z axis evertime I move teh head up and down.

And thanks for the link. I have bookmarked your website for reference.

Veteg,


Wow, those machines are extremely impressive! Look virtually like commercial quality machines.
Thank you for posting the pics and translated "recipe".
I have joined Peter's CNC Ecke forum but have trouble with finding where any of the tests and recipe's are for E/G. Wish I could speak some German.

Could I just be a slight pain(nuts) and clear up some of the translation?

Fugensand - ? Is this a particular type of sand?

Epoxyharz L und harter L von R&G.DE - Epoxy Resin and hardener
I assume it's from here;http://shop.ezentrum.de/4DCGI/ezshop?hid=27&sprachnr=2
But does not specify which or is it not that crucial? Do you know?

Have you started any build yourself?

Myself, I'm playing with the idea of making some parts for a grinding machine I have in mind.

Thanks also to BW for the blog! Very nicely done and great pics.

Cheers everyone!

Hello mates,

Here the link for the right epoxy,
It`s a epoxy resin and a harder.
You need for both the L type
and mixed 100:40 by weight or volume.

This combination of epoxy and harder need to be mixed with 3 extra components:

(you have the mix of epoxy resin L and harder L (100:40))
mix this with;
- basaltsplit (small rocks named basalt)
- sand 1 ( quartz sand
- sand 2 ( fugensand (sand used for construction, fillersand( to fill )))

I would love to make a machine, but dont have money.
( 3000 euro, rolled preloaded double nut screws 0,023/300mm, preloaded linear bearings 1 axle 2 rails 4 wagons, Hf servo drive spindle, closed loop controller. etc. etc. etc. ( we should make 5 or 10 for us here)

G'Day Veteq,

Thanks for clearing the ingredients mix up. ...and the link too.

Sorry to hear you can't do your dream machine.Yeah it's expensive to do a build. Especially new components!
Even bargains I got on eBay add up so quickly, but I wouldn't have a chance otherwise.
If eBay is still not your thing, you might try Chinese parts sources from Alibaba if you're desperate like me.
I've only just started looking into this myself. I don't know if it's worth it yet because the real price is in the quality (unknown) and the import costs.
I'm only considering this because I can not afford one sold here (around $2000USD + delivery) and no one makes them in Australia.

My only other alternative is to make a base myself out of E/G! Well, I might try it anyway if all else fails.

Good luck Veteq

Regards to the Netherlands from Australia!:wave:

hello again,

indeed, i have to be realistic, the paypal account is made.

Here another nice link, one off the starters of the german epoxy thread

http://www.thomas-zietz.de

choose "neu im programm".

Beautiful renderings! Do you have photos of the actual machines? They look very nicely designed and implemented.

[Mavyryk]

Thanks. We try for a blend of beauty, practicality, and performance.

The motor and encoder/scale images are real pictures taken from shipped IronMan XE systems.

The PCX and Spartan are renderings.

Stay tuned for real pictures in the coming months.
