Vacuum table Setup Advice

[GEOFFREY]

Just to put my twopenorth in. I personally think that if you are cutting small parts in ally, don't bother with trying to use vacuum without some other form of clamping device. Use clamps, jigs, fixtures or whatever, but I think you will waste a lot of time and money with vacuum alone. I also do not believe that you will get away using only a single phase pump. If you are cuttig small parts from a large sheet area, it may work, really vacuum hold down is fsr better suited to timber/board type products. Anyway, good luck, but don't wastew too much time, effort or money. G.

How is 250mm by 150mm small?

It's not untill you start cutting thru it.!! . . . Just like a parachute works fine when canopy is inflated but punch a few holes in it and you'll reach mother earth much sooner than you'd like.

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

[andy_con]

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

[JAZZCNC]

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
