Vacuum table Setup Advice

[andy_con]

im after some advice on vacuum pumps for a vacuum table setup.

i want to do exactly this -



no idea if its the right sort of table, but been looking at this table as its the perfect size for my mill

would this pump do and im assuming im going to need a liquid seperator as my mill has flood coolant?

I think it should work. A friend has similar size pump and the plate you aim to use is fairly small.

ok thanks

im assuming as im machining all the way through a vac-mat will be better as it wont suck as much coolant in and a proper holed matt?

It will not suck dust and metal, that's for sure, due to the micro holes. It will hold steadier also, due to friction.

how does it work with a normal holed mat? does the table suck metal into the pump?

(sorry ive never used a vacuum table before)

Depends how fine is the sucking hole. Not the vacuum hole you see on pictures 3-6mm, but the real sucking hole in the vacuum hole center, it could be 0.5-1mm . Its a good idea the vacuum table to be made from 2-3 pieces and that could be dismantled for cleaning or repair.



The vacuum table from the first link was ok and they have mats. any mat from superstore 2-5eur per meter will do the job, some experimenting is needed. cause they sell ridiculously expensive the mats.

Or just DIY around the vac-mat

My friend Ralf use's one of these pumps http://m.ebay.co.uk/itm/271844104827 for his diy vacuum system quite successfully, below is the build video from his youtube channel:

There are some other videos there too, detailing his machine and the vacuum setup.

We develop a thin film for hard works may be it can do the job? Please take a look at the movie. https://www.youtube.com/watch?v=PbCqkUomf5M
