Mist Coolant (Fogbuster)

I like that. Really neat.

Hafta say I started out considering using a bar in a toolholder to carry mine but I didn't want to "waste" a toolholder and, not having 3D printing, making a specific mount seemed too much trouble. But my T2 styes have those locating pins just right for hooking over so …

My flexi-nozzle uses the same interlocking flexi-tube as most the flood cooling systems do – The air supply flows inside that, and also within is a 4mm OD FESTO plastic tube that carries the oil to the nozzle. The base has two entries – one air and one coolant, from the mixer contraption. The base has a magnet undet and can be parked anywhere convenient..

Magnet under base – from a small loudspeaker…the groove around the circular magnet below is where the voice coil used to be..

Coolant inlet pipe fitted – 2nd hole is air inlet.

Well its been a little while, and I've been a little busy work, but I have finally got my fogbuster copy build and running. I built the main unit a while ago and just needed to sort out a bracket to attach it to the locline. I don't have a 3D printer… but I do have a CNC machine now! The bracket design was way over the top with lots of fillets and curves, but it was a good opportunity to learn how to hold such parts. So I loaded the system with some coolant (big thank you Alan Wood for supplying some coolant to get me going!) and started cutting out the bracket.

In operation the coolant valve only needs opening a crack, and with less than 10psi it pushes the chips away from the cut and provides a steady stream of coolant droplets without any mist and fog!

The only time I got a fog was during testing when I had filled the coolant reservoir with water (thankfully no oil) and tested the pneumatic solonoid valve without the needle valve on the fogbuster in place… Oops! A litre of water instantly atomised over the workshop.

Thank you for the help everyone.

Congratulations on a very smart job.

You should do a write up for MEW.

Although the internet finds plenty about fog buster projects it all seems pretty Americentric and "what I did with some handy bits" sort of thing. Fair enough if you want to play development engineer but a lot of people would prefer to simply follow the words and music to get something neat, workmanlike and functional that "just works".

Your version looks to be just that.

In the winter would this not be to invite condensation in our cold workshops and all that goes with it ? When using old speaker magnets I fill the gap where the voice coil was with resin to stop metal particles or swarf getting in. Very smart job ! Best wishes, Noel.
