Chamber flush - oil or water soluble?

[GenePoole]

That ain't happenin.

I just use a small dam with oil absorbent media. I throw a small sheet of this into the catch bucket as well and change it every week or so. I also have a cheap brix refractometer from amazon. I check it every few weeks.

After using my set up a few times now I’ve decided the catch pan need to be turned like machinest John’s. being parallel to the ways it’s just to long for my liking.

I generally keep an oil absorbing pig mat in the bottom of my chip tray anyway...

Are there any modern coolants that don't end up stinking and growing biomaterial?

I've never even heard of anyone actually having coolant go rancid--at least in the last 10 years or so.

This is looking nice.

ASTRO-CUT BCL - Monroe Fluid

ASTRO-CUT BCL is a heavy duty BIOSTABLE semi-synthetic general purpose metalworking coolant containing approximately 20% mineral oil. This product, when diluted with water, forms a translucent amber emulsion which offers excellent workpiece visibility, good lubricity, and superior cooling...

A friend used Hangsterfers S-500CF (and chlorinated prior to the CF) in his CNC’s for many years. I have a bunch of it I got from him. He never had issues in his machines with it and neither have I. He runs tramp skimmers but is super lazy about checking the concentration. Too busy running machines I suppose. He’s using something else now but I’m blanking on what it is. I haven’t heard anything negative about that one either.

I was concerned about coolant going rancid so did some research and found one that people recommended. You guys probably can't get it over there but I'm sure you'll have something similar or better. Proper workshops are turning it over all day so it's not such a big deal. If I started having problems with it going rancid I was going to add a little fish tank aerator on a timer to prevent it going anaerobic.

Saw on Titans on CNC one shop was having issues. Turned out someone was pi$$in in the tank on nightshift!

I use Hsngsterfers in my little Haas cnc mill and also use it in my manual lathe that has a built in sump and pump. Sometimes my machines sit for weeks without use and the coolant stays fine and doesn't get rancid.

This is why I hate people.

Emailed Monroe this morning and asked what to run on a manual machine that's semi-transparent and good for turning, drilling, threading, etc.

They said BCL is the ticket.

Common chlorine bleach will do a pretty good job as a sump dis-infectant

 

[LVLAaron]

Speaking of... if anyone is 2 feet shorter than me and wants to come take the sump out of my 1440, I'll buy you a pizza.

Is this scary to anyone else?

 

[DaveTooley]

I was ashamed of my worn out catch pan so I replaced it. That's 3 chambers worth of debris.

Not really.

I'd be curious what the MSDS for Simple Green says. That shit will drop you to your knees in a confined space and they sell it at Home Depot. I've never heard of any serious side effects either.

 

[LVLAaron]

Thanks, and good point.

I ended up dumping a gallon of astro swiss in my tank and will just run that. I just need a little drizzle for threading and drilling and it seems to be fine for that. I just don't trust what I can't see, and I can't see under my cross slide/compound/bearings, etc. I'd be devestated if it got rusted in there somehow.

 

[LVLAaron]

I'll try a Noga or a proper kool mist system.

I got the noga mini-cool. it's worth every penny over the 20 dollar chinese knockoff.
