I´m planning a plasma table for mass production of rondels 600 mm dia from 1250 * 2500 mm sheets, blue anealed steel. The surface of the material is very smooth with a deep blue color, and I need to keep this finish. I haven´t been working with plasma-cutters before, and now I´m worried if the slag/ dust from the plasmacutter will collect on top of my material or if most of the slag/ dust will blown through the table. If the material gets dusty I´ll have a problem later when I´m working the material i a press (scratces in the material etc) and spotwelding it (scratches in the electrodes).

I want to make a automatic loading/ unloading system for my machine and I don´t have time to dust off each part. This is going to be a fully automatic factory. Yes!

I'm sure a good down draft table would minimise the dust. Murphy's law (If it can go wrong it will) dictates it will not be dust free under any circumstances.

What type of material are you cutting? If it is steel you can run a peice of tube with magnets along the surface right before stacking... If it is automated loading you will have no problem mounting a row of magnets somewhere before the sheets are stacked. And Yes the magnets pick up every little bit of particles...

The magnet thing is a good advice. Thanks! I´ll be cutting mild steel, 0.6 mm to 1.5 mm thickness. Perhaps the dust problem will be less siginficant compared to cutting 1/2" etc. I guess the torch must move quite fast on such thin material... Servos?

Servos or steppers would work... Plasma has no cut force on the head, so I would probably go with steppers... Just use a 4 to 1 gear or pulley reduction and your IPM shold be were you need it..
