Re: [CAD_CAM_EDM_DRO] Vacuum pump for vacuum chuck?

Tim,
 
Maybe both a shop vac and a vaccuum pump.  Using check valves it is possible to set up so that the shop vac starts the process and then the pump takes over to put a bit of presure on the part.   Remember that you only get about 14psi clamping pressure with a good vacuum pump.
 
 I use a Robinair pump for some non machining tasks (RTV evacuation) and am pleased with it.  Lot of bang for the buck.

Thinking that for a variety of my projects I need a vacuum chuck. Any
suggestions on what type of pump I should be looking at? Do I want a
real vacuum pump that can pull a relatively high vacuum, but the CFM is
low or is there another style of pump that would work better. Most of
the items I am expecting to clamp will be slightly to moderately air
permiable.

Thanks,
Tim
