How is 250mm by 150mm small?

What is it exactly your wanting to cut and how many and size of holes/cutouts.?

no word of a lie exactly this



I machined this case in separate panels, it took forever. so I want to machine these panels but on a vacuum table

Not sure why that would take for ever and certainly doesn't need a vacuum table. Those panels would take minutes using conventional hold down methods.!
Couple of intial clamps until few holes drilled then screw it down and carry on. Simplizzzz

yeah so square up on the table using a test dial.

clamp

drill some holes

remove and fix down to a jig

put back in mill and re-square using test dial

machine the rest.

or put straight onto a vacuum table and do the whole thing in one go

No no your making it far more complex than needed. If one off then just have base board you can screw into. Clamp it down do the first op which is drilling cycle then stick a few screws into it. Remove clamps and carry on with rest of the cycle.

If got lots of same to do then do the same but with permantent fixture jig with toggle clamps and holes already in to accept threaded bolts.

Standard stuff really and not complicated or timely.!
