Building CNC machines from Epoxy+Granite

in the german CNC-forums they show their selfmade 'stone'-bases and mill-beads and discuss different mixtures and methods of mixing and finishing. The best mixture seems to be small pebbles, coarse sand, fine sand and some glass-dust or cutted glass-fibres with 6% to 10% epoxy.

Beefed up Minimill | OpenBuilds

I wanted to use the minimill to mill aluminum. At first, I had some wobble due to the wheels, so that didn't really work. I already had a 500mm long C-beam to use for the X-axis. I stiffened up the column by adding 2 C-beams together and filling the inside cavity with epoxy granite mix (which added about 4.5 kg or roughly 10 pounds), which I ...

Langmuir MR-1 Gantry Mill

Langmuir MR-1 Gantry Mill. Hopefully a YouTube video will be acceptable to all involved: while still allowing for discussion. The landscape is ever increasing for the gap between hobby and industrial machining. Interesting, looks to have quite a bit of steel in the frame, unlike the Triumph.

CNC Milling Machine : 18 Steps (with Pictures)

The epoxy granite is a mixture with epoxy and gravel filler with different grain sizes. The sizes are chosen to make the most possible dense gravel mixture. This saves expensive epoxy and it makes the machine heavier and more stable. One important thing is to make sure that the mold lies flat on a reference surface.

Epoxy Granite > Filling steel tubes with epoxy granite- machine before

There is research data to show that filling steel with epoxy granite results in improved vibration damping. I am planning a steel weldment with epoxy granite fill for a metal mill. However, the epoxy granite may end up a bit different. There are some interesting papers on using crumb rubber (rubber granules) in the mix to improve damping.

Epoxy Granite Inquiry

Epoxy Granite Inquiry. Say I was building an industrial sized cnc mill out of EG. It is not practical to prepare an entire batch for one casting. From that point there seem to be two reasonable options. Cast the frame in parts and bolt them together. Alternatively, still cast the whole frame, but in layers.

Advice needed on filling my mill with EG

The stiffness of epoxy granite being on the order of 1/8th (maximum) that of steel, means that if you fill the .75" thick sidewall, 8 inch outside diameter steel pipe, you've only added 1/8th of the difference (402-226)/8 is 22in^4 equivalent. this means the epoxy granite will take 22/(226+22) parts of the strain, or about 9%
