Nick, I am saving up for a fog buster setup which does not cause misting (There's a couple of videos on youtube). But it is quite a big more expensive than the vertex setup so I'd be interested how you get on with the vertex set-up.

Heres the Noga same as Fog Buster in operation. **LINK**

Better suited to very light milling, lathe work forget it.

I did get delivery a couple of weeks ago.

IMHO Rubbish.!!! ………. A total waste of time and money.

Got one thinking it would be better than the drip feed we rigged up for the show CNC's as mentioned in a previous post.

Not so, either all or nothing and when it was working you were eating it. Now gone back to a more engineered drip and air feed of the admittedly lashed up setup we had on the ARC demo CNC's.

This Vertex unit wants to be rehoused in that fiels just off the M1 at Shepshed where my Iphone now resides.

Replying to Bogstandard2 (mainly)

Not having ever set up a system and only ever having seen the system rigged up by Arc for the previously mentioned show my understanding was that the primary function of the air supply was to blow the chips away and prevent re-cutting (hence improving the finish) and the addition of the oil drip just added a little lubrication to the cut. The requirements for milling are obviously different to turning where the workpiece throws the cutting oil everywhere and getting rid of the chips is not an issue.

I am just thinking out loud here, has anyone ever considered vacuum removal of chips, I have a kool Mist system, I came across at auction, got it for a tenner I think, about 5 years ago, I've never gotten round to trying it, partly because the nozzle is missing and also I read about fogging problems so pushed it to one side, this thread has re sparked my interest, but I got to wondering if it could be workable to use a system of spray and vacuum, and possibly a centrifugal separator to remove chips " lets say Aluminium I machine a lot of this stuff, and re cutting of chips is the biggest cause of tool wear and poor finish, especially in deep pocket machining.

Your thoughts……….

Most of my daily work is aluminium 6082 not the best to machine certainly not the worst. Can fill a wheelie bin in 1 1/2hrs to give you some idea. Cutters last absolutely ages even hss and leave a decent finish even at 1250rpm machines top speed (too slow.) Main reason I don't or try not to let the cutter and job heat up. If it starts to get warm I don't bother with Noga or coolant pump just a squirt with soap bottle and coolant.

Slotting deep I also do weekly mainly dry because can see what I am doing visually. Every so often blow out with air gun, no vaccum available will have half that power plus be cumbersome. Depths can be 6 dia x 24 deep to 8.5 wide x 42 deep interrupted or not, never a problem and need to be a good finish on expensive items.
