Need Help!- CNC coolant help.

I was wondering if theres a flood coolant system thats ready to go that would work with a minitech mill, pan splash guard, pump and any thing else i need. And what is a good brand of coolant that wont harm the minitech mill and that i can wash underwater with out having to worry about toxic stuff splashing or going in sewers.

I have used compressed air but then noone should be without glasses that cover absolutley everything so ther is no chance for bouncing stuff to come in from the side to the eyes becahse it flies small metallic parts all over.

Another way is water but then the metal will corrode alittle if it is such a metal.
Can also use ultrasound washers to was the parts if you use alittle bit of oil

My system is just a cheap solvent tank from HF. Probably $49. It came with the tank, pump and flexible nozzle. I added a valve, some hose, and modified the tank for the hose and drain.
I use Koolmist 77. I am able to powder coat parts without having to wash them after machining. I do sand them some, but not all parts get sanded. It does not interfere with PC, so it is some good stuff for me.

The only drawback is that it will break down polycarbonate if given half a chance. It simply wicks into the material and reduces its impact resistance.
I imagine that larger machines use a better type of polycarbonate that may be coated on one side or both sides to resist any coolant leeching in.

It is said to be non toxic and the chemicals are inert. It also says to mix 4 ounces of coolant with a gallon of water. I probably use just a little less than that. Never have any rust on the machine or in the chips left in the tray.

Koolmist 77 seems to have a few drawbacks. I wouldn't mess around with anything that you have to worry about. I'd go with Blaser BC 230 coolant. It's about as close as it comes to "mix it and forget it". Human, machine and environmentally safe. Check out a review on the stuff at http://www.cncreport.com/product-rev...oes-it-cut-it/

I've also been using koolmist 77 for years I like it because of how clean the parts come off and it never has irritated my skin or lungs.
Usually if I'm running aluminum and not hogging compressed air works great
Team pierson I've also heard good things about Blasocut.

bigtoad... maybe you can confirm or correct this. I had a neighbor that switched coolants and it started to turn his stainless steel guide covers black. I'm thinking it was koolmist, but I might be confused with another. Any experience with that?

[LeeWay]

I haven't used any stainless. I haven't noticed any staining other than when it dries, it may leave a blue spot. It can be wiped off though.

I use 2 - 5 gallon buckets and some tubing connected to the loc link coolant hose and nozzle setup. Works like a champ, no hassle, blasts coolant. A pump from an aquarium could be used to run the coolant from the lower tank to the upper one for about $30 or so, but I just use an empty coffee can and scoop it up every hour or so of machining.

I use a detergent base coolant,many are available, clean parts, good lube in the cut. Misters are nice, but I like breathing air only.

I have been using coolmist 77 for about 10 years now and use it in both misting and flood. I use it misting on the cnc mill for mostly aluminum and use it in a flood application in the haas lathe. I also use it on the cold saw and doall horizontal bandsaw. Parts come off clean and on the cold saw its nice because once dry you can mig weld right over it and no porosity problems. I have 1 job that uses allot of 1x065 square tube with all kinds of angles and having to clean cutting oil off all the parts would kill the job. Yes there are probably better cutting oils out there but it is easy and works for everything I need it to. Need more simple things in life.

any sugestion for a good flood pan that would catch all the coolant, that can support a cnc and have a place to hook up some tubing? maybe even a flood table.

Are coolant reusable? like if i collact the coolant i can reuse it for more machining or once used it over?

Dont think im gonna go with misting, like the other one has said, i love natural air. I live in an appartment so air circulation isnt great.

[nanopile]

Hehe, i made a temporary airventilationsystem using a wodden frame to vent the air.
But then that is mostly for the soldering i do, that smoke isnt supposed to be good to breathe.
