Try ebay, or just google it and you'll likely find what you need.

I just bought one off ebay and it works just fine. They are pretty cheap for just a generic one. You may have to get creative on the plumbing though.

I've done many Vacuum Chucks for aerospace parts. send a few more clues to the sizes needed, Lip seals and correct vacuum bleeding is the key. Correct porting and manifolds too.

try Vacmat or better yet make your own. you are in a machine shop aren't you.

Ive got several vacum systems, the best ones are using the VacMat mats
as they give a good friction in xy and very good seal and the mat is .09 in thick
so you can machine down into it as well.

they want a bit too much for the plates so i made my own but i do buy the mats. simple stuff making the plates

Thanks everyone,

We did make our own,however, the pump we used did not have enough CFM I am figuring to hold our parts good enough. Thus the reason I asked. There is several configurations available and I didn't want to make the mistake of buying the wrong one..

the pumps i use are simple compressed air powered with a relatively slow pump down time. so i put a tank in line between the pump and chuck giving me plenty of instant power when i engage the chuck. also helps with leaks that occur when cutting thru the part into the mat

there is a place in Baltimore that sells the vacuum system that runs off the shop's air system the unit is about 6" x 4" and you can magnetize it to the machine cabinet. i am not sure of the name but i think it is called Linnair
