Swarf cyclone pre Henry?

[julianf]

My CNC machine generates a fair bit of alloy swarf.

It's not long curlings at all, but small chips / splinters.

I suck it up with a Henry, but it's tiresome changing bags all the time. Plus they get damp from the cutting lube and that reduces suction anyway.


I'm thinking of getting one of those cyclone things and bolting it to the top of a blue plastic clip top drum.

But...


Is a henry a suitable driver for this? It's a low volume high pressure device (so far as I'm aware) whilst most extraction systems are high volume.

Anyone used a domestic vac cleaner on a cyclone before? And how did it work?

I’m probibly speaking rubbish, but since the cyclone is directing the swarf into the drum, very little will go to the henry. If it picks up the swarf, then it should still do that atrached to the cyclone.

I have a mini cyclone attached to my sandblaster, and the dust goes into a coke bottle screwed onto the 3D printed cyclone. I run the whole thing from a 12v car vac (like a micro henry). The vac never fills.

Julian have constructed 2, the Chinese plastic variety with 2 cylinder vacs sucking used for wood, the other a variation of the http://www.jpthien.com/smf/index.php?topic=137.0
Used for removing cast iron swarf & dust this has a Clark fan sucking through a 205 ltr drum
There are a few threads on here about them

Hope all well

Chinese cyclone as an intercept between blast cabinet and a George (wet Henry). Works well.

Ive often wondered if one of yhose ash can things you see in aldi would work for picking up swarf

I use a Dyson in the garage for cleaning the chips / swarf off the mill and lathe.

I keep eyeing up a large road cone that has been sat across the street from our house for a while, it has cyclone potential I think.

is it alli or steel alloy?

You mean like this:-



It works for me but on powder coating, it could do with a better suction, one of these days I will get a squirrel cage fan on it. I have a cooker extractor multispeed motor that may get strapped to a board as a test.

I have one - theyre a bit rubbish. Hoses seal badly. Internal filter just blocks up, so you remove it, and then all the light stuff goes through to the henry anyway.

Plus capacity is limited.

(edit - mine is the non powered version)

aluminium

 

[julianf]

If it picks up the swarf, then it should still do that atrached to the cyclone.

I guess what you say is obvious really! Ive just had so much bother with my aldi thing leaking (and hence reducing suction) that maybe i cant see the simple answers any more - thank you!

Looking on ebay, seems there are two types.

This one -

Which people above have.

And this one -

Same sort of cost. One mounts inside the drum (ill probably use a 60 ltr blue clip top drum), but other than that its just the bore.

Im guessing a henry nozzle is 2", right? So id want the white plastic one? Or do you get some sort of increase in vortex from restricting the diameter or something (ie is the 2nd one just smaller, or is there some maths behind the reduced bore?)

 

[julianf]

just one more -

Wrong.

A very quick measure on Henry
Tools 30mm dia.
Hose 37mm OD

Boss to henry body:
ID 44mm
dia of screw in boss 58mm

It is cold and wet this morning and Henry is still in the van so don't take those as 100% accurate.
