Reply with QuoteHi guys,
What is a cheap method for making cast in inserts? I hope to avoid having to have a whole lot made.

a few post back the German machine looks like a far better solution as well as being easy for me to cast so I am now rethinking my ideas and considering building something very much like the first smaller blue machine.

Hello jestah.View the links from post 4511-http://www.ktm-reiseenduro.de/tz/menue.htm-right click and view projects.Can be improved by metal inserts are cut, aligned and latched into the mold.In this version of the packaging system of the machine achieves the highest stability.Yancho Yanchev
What a way to upload photos?
Hi - here is Thomas from germay again!
Wow - your casts looks good!
Several days ago we produce a new version - called FS3MG.
Here some pics:
Hi Thomas,
That looks really professional.
Is this design also a two part design?
Do you have any pictures of the real machine yet?
Regards
Sandi
Hi!
Yes two parts.
Real pic's?
The pics above are the real machine.
Thomas
Congratulations to Thomas, the machine looks great.Do you steel it?Would it be convenient to share prices of the parts?Especially at ELTE spindle.Thanks,success Yancho Yanchev
Hi!
The parts are from mineral casting with steel-parts in it.
The surfaces for linears are specialized moulded.
For prices please contact me: thz@thomas-zietz.de.
Thomas
Thomas,
My apologies.
The pictures look so 'immaculate' that I was sure they were generated from the 3D CAD design.
The workmanship is so good and it is finished off so well that it looks like a generated image.
The machine looks great!
Regards
Sandi
Sandi,
okay i know what you mean.
Another thing: the photos are made with a "real" camera (nikon slr) and the right light.
Bye
Thomas
Beautiful machine Thomas! I have admired your excellent machine designs for a while now.
When you said; The surfaces for linears are specialized moulded does that mean you don't surface grind the surfaces after molding? I thought that was the standard way?
Or do you hold the steel surfaces already aligned in the mold, when the EG hardens?
Hi,
we don't grind the surface. We use a spcial resin with steel-powder and mould
the surface exactly with exact grinding gauges.
Bye,
Thomas
Excellent info, thank you Thomas! It's good to know precision features can be molded in and remove the secondary machinng processes. Clever technology.
Another concrete/granite build thread;
http://www.cnczone.com/forums/genera...ine_build.html
Where he has cast a machine base (ok out of reinforced concrete, not EG) but it might still have some interest to people in this thread. He also seems to be making a gantry from granite surface plates and is talking about EG too although the thread is new and he has not used EG in the build yet.
Hey Thomas,
you are the man that made it from hobby to pro...the first one from the forumcult...cool..!! Been reading for years now on cnczone and ecke.
Could you tell or maybe efen show a picture of the precision Jig..?
How cann i make a jig for my own machine in time.
Think you pour the base and gantry in the mould with there contact patches.
After that you pour in the surface stript for ballscrew and slides on y and x axes..?????
Kind regards,
Roy
we buy the linear surface material from Moglice. however, the replication gauge is very expensive, in China, no customer can afford it.
Besides replication and machine, is there any other method to make precision in linear surface?
Regards
Steven
Think Thomas uses DWH310FL...?
Is that replication gauge a very big precision jig?
For placing the linear surface material in and glue them in place?
yes, the replication gauge is very precision jig, and the price is very expensive.
Could one off you guys post a picture of it, or is it secret..?
Hi!
I don't want to post all over the acquired know-how here. Hope you understand.
But one I can say: the moulding with a gauge iss the one and only
method for cheap precision in series production. Grinding steel-inlays or griundung mineral casting itself is a mehod too, but today is no longer applied almost. Anyone who thinks that gauges would be too expensive, goes IMHO the wrong way. I speak always of a serial production.
And no - we don't use DWH today.
