Thread: Epoxy granite or mineral casting
the machine base is for engraving machine
In terms of recipe and process, it's not easy to say in short words
That is a nice looking machine there. The type of mineral base and how you go about it would be of interest to a good number of us for many different reasons (not just machine building). IF it is part of your day job I could see a bit of reluctance to part with the information. If it is not in that type of area please do tell and as far as long words and thick reading, have you ever looked at a TM or FM for a vehicle from the US military (6 pages on how to check and change oil and that is not including any special models of the vehicle).
Give the guy a break, he's only trying to make a living selling his machines lol
This is my first post at MYCNCUK
This is an old thread but I hope the information helps, I have made a machine using Epoxy. It has a cast base and also two cast carriage ends. And these have a low friction cast in bearing surface on round shaft.
The machine is loosely based on the Worden grinder, however no sheet metal is used. It is very solid I can just lift it. There is very
As far as the epoxy mix is concerned I just used fine screened quartz gravel from a garden supply and washed sand. And Yes I used a little steel reinforcement. It is not hard to do and you do not have to use advanced calculus and have a chemistry degree to get a good result. Most resin suppliers are familiar with casting with epoxy aggregates.
I apologise for just posting a link here but I did the write up about two years ago here: New technology in Model Engineers Workshop | Model Engineer
It is a fairly lengthy post. there are many photos.
The machine has been in constant use ever since, I use it to grind lathe tools, the finish is almost mirror with a diamond wheel. No chatter.
Since then I made a CNC router with a mate for a community project A "Mens Shed" Located at Bright Central Victoria Australia.
Most of it is laser cut 5mm steel.
If anyone is interested it can be found here:
Laser Cut Frame CNC Router New build
Next up is a new router for me this time. I will post directly when I start it. It will also be based on laser cut parts.
