Hello I am Portuguese and I really liked your project and wanted to make a similar but I wanted to know what dimensions of the engine you used thank you and keep up the good work
With the engine you mean the vacuum pump? Currently, I plan to use one, two or three pumps of the 2660 series from Thomas (by Gardner Denver). Used ones are very inexpensive on ebay.
Currently, the table isn't finished. But I milled a small vacuum pad before and it works very well. For the test I only used one pump of type 2660 from Thomas by Gardner Denver. I published new information to the choice of vacuum devices (see hackaday.io/project/166349-diy-vacuum-table/log/166256-more-information-and-schedule-of-next-video)
Congratulations for your work! Please I have an answer. Why the drills must be 0.2 or 0.3mm . Which is the effect that it causes. what happen if i choose 1mm drill?
Thank you very much! The larger the drills, the larger the air flow is when holes aren't covered correctly or milled through the workpiece. It is a simple calculation. The airflow depends among other things from the area (cross section) of the holes. Area of a hole with 0.2mm diameter: pi * 0.2^2 = 0.13mm^2 Area of a hole with 0.3mm diameter: pi * 0.3^2 = 0.28mm^2 Area of a hole with 1mm diameter: pi * 1^2 = 3.14mm^2 Thus, for one open hole with 1mm diameter you can have 25 open holes with 0.2mm diameter and 11 open holes with 0.3mm diameter, respectively.
Die genaue Zahl habe ich leider nicht mehr, da ich zwischendurch mal Bohrer entsorgt habe :-D Aber es sind sicherlich so um die 18 Bohrer gewesen, wobei 10 davon wirklich billig waren, also die waren auch qualitativ recht schlecht. Am Ende haben es die 0,3mm Bohrer gebracht, da konnte ich mit einem einzigen Bohrer die halbe Platte machen.
Geiles Teil...!

yes I mean vacuum pump but don't know how much flow you need to have for this messa
Have you tried to see if the table works?

Hello, very good work. can you tell me where you bought your 0.3mm drill bit? thanks
Bought them on ebay. Tried different brands. The drill bits with a bigger shaft worked best, a good clamp required.

Oh Mann, 0,2 Bohrungen... wieviele Bohrer/Fräser hast du verbraucht? Grüße Arno
