Dust removal for carbon fiber?

[vinot]

I'm finishing my milling machine and I still have no idea how to better remove the dust. Originally I worked with carbon-kevlar and a carbide saw, and it was the hell but I think mainly because kevlar, it can't be cutted, only bitted. So I don't know how dust will be working only with carbon laminate and a milling.

Searching in cncforums I saw the "cyclone" system, but I don't know if it will work with carbon dust in a milling machine.

Will I require a complete clossed room for the milling machine? can have a well powered solution to avoid room?

any suggestion will be very appreciated.

thanks,

Toni

Enlose the area and the tool and put a vac to it running to an outside filter.

Thanks!

anyway I have resolved it. With an industrial wood vac, very surprised about results, almost clean. No problem with carbon dust nor polyurethane dust!

really nice!

You do have the collection system on the outside right? The carbon dust will go trough standard bags, you need something as tight as a couple of microns and they are really expensive.

I solved carbon fiber dust problem year ago when once tried with coolant.

No, it's qutie a simple air vacum, tomorrow I will post some photos about it. Anyway, I only have to do some cuts over a laminate of fiber (3 mm of section).

Till now (very few cuts, not yet solved cnc routing ( the dust becomes absolutely absorved by vacum, and filter looks fine. Also it becames a mixed powder of maybe... 0.01%?? within the polyurethane. Just as a curiosity, I will post also a photo looking at the router: I attached an "air deflector" to avoid air stream against the working area. Carbon powder from magnets appears clearly, much more than I could see at the bag of my air vacum!!

Regarding coolant, the same way: not too many cuts to do. Well, till now... I hope my job is going to rise up now with my new cnc milling super-machine running! No, seriously, I don't imagine how much dust removal I have to do to get involved in a serious problem. Of course that I will have to do lot of improvements into my first-new machine to use coolant, so...

Tomorrow I post them...

A word of advice: You are going to want to give everything a good wipe down every once in a while. I have worked in a composite shop dealing mostly with carbon fiber for a little over 4 years now, and if i know anything about it, i know that the dust gets EVERYWHERE. And there is pretty much nothing you can do to trap all of the dust. It sounds to me like you wont be creating near as much dust as we do, but it can turn into a real pain if you dont keep on top of it as much as possible. Our shop is decently sized, with all of the grinding, trimming, cutting, and so on done in a room separated from the rest of the shop and the dust has still managed to find its way into every nook and cranny in the place.

Edit: Forgot to mention that you would want a dust removal system in place as well, but it seemed like you already knew that much.
