i saw a youtube video with a twist on the epoxy machine frame
https://www.youtube.com/watch?v=eAe3TlsVKcc
Its a sheetmetal skin thats filled with epoxy & rock
The video also shows a very nice spindle
and uses real precision workholding system.
Once I had a Swiss Dixie CNC electrode mill for use while working at AGie
It had no table at all, just a System 3R shank bolder.
That is a hydraulic clamping bore for 20mm shanks.
The shanks has cross pins to establish height reference
The bore established X0Y0
by turning the unclamped shank against a vertical pin, the C reference
was had.
and 4 such pins allowed 4 indexes at 90deg.
Work material was brazed onto the top end, and could be
removed and replaced with a few microns of reproducibility
This allowed multiple work pieces to produced accurately
That was great for sink EDM .
The video shows ITS tooling clamping work to table
which is reconfigurable but not a persistent true position like the Dixie.
I favor no table for small CNCs, instead a workholding system like the ITS
( or Erowa 3R Hirschmann Istema Imea what you like or can afford )
