- Is the cutting fluid in your coolant tank full of oil and chips? Worse yet, is it beginning to stink from the effects of bacterial infestation? In this video, we first look at cleaning out a marginally dirty tank. Then, we move onto a really dirty tank, and the steps involved in cleaning the machine's entire coolant system when it's been overrun by neglect and contamination.

Our shop is so busy right now we don't have time to spend to clean our tanks that well even considering some of them really need it
That was satisfying to watch
Any chance you can demonstrate how in the world you clean out the integrated coolant tray of the ST10? So far its been a frustrating mess.
0:27 delicious smoked cheese & garlic soup!
🤢
Now what do you do with the extra 100 gallons of cleaners and rinses? Some of us small shops don't like to have barrels of waste water sitting around.
Super perfect
Inside our machine, we have a chip auger system. The coolant we run drains down to the auger and collects all the oil and chips and get mixed in. if the coolant levels in there rises too far up it'll get drained out to the reservoir tank, but we still get all the crap left behind in the auger. I've been trying to find some sort of drain plug to get rid of that and can't seem to find it anywhere. Any recommendations on how to deal with that? I'm a fairly new CNC Operator, and our shop just got their first CNC Machine here, so no one knows a thing about CNC Machining or how to properly maintain them. Thanks!
Does anyone know what the chip scoop used in this video is called and where I could get one? any search for chip scoop gets me restaurant supplies.
now show me the best way for a mini mill, as you can't pull the sump out on those and it causes real problems.
Pretty ridiculous if anyone lets their tank get to this level. When I was maintenance at a shop there were a couple dozen machines to maintain and the tanks were cleaned every single month. Tanks were emptied with a chiperator which sucks up the coolant and puts it through a filter and holds it till it's time to put it back in. All chips and oil (which never built up) was cleaned out and the tank wiped inside and out with cleaner and all screens cleaned. Cleaned coolant was returned to the tank and if top offs were ever needed we had a DI water system that ran through the shop with a valve system that siphoned off pure coolant from a drum that could be set to 7.5% just by the trained eye and checked with a refractometer. That fresh coolant was ran through a hose to any machine and whatever percent could be added to correct the concentration. Coolant tanks absolutely never had a smell to them and the haas machines I took care of were clean inside and out, top and bottom, even under the way covers with extra care. It's no excuse to have crap in your tanks. If you can't hire a entry level worker do it yourself, have an operator do it, or just suffer with your nasty shit!
Small shop with high demands placed on it. Things fall behind. Hard to get ahead of these things when you're constantly digging out of a hole.
What type of coolant is used in this video to remove the alkaline treatment?
That was cool
We never did any of this when I worked for an engineering company.
But at least I know why the coolant smelled the way it did now.
Yeah, it's a total biohazard. Makes me wonder why they don't formulate the coolants with a biocide agent since this is such a rampant problem.
Thanks too
we use a Desoiler that separates the oil from the cooling avoiding to clean it manually
Это ещё идеальное состояние. Вот когда открываешь бак, а там как в фильме люди в черном где в ячейке камеры хранения, на тебя смотрят пришельцы и кричат славься джей😂
It's good to provide oil skimmer for that machine
what kind of coolant do You recommend
I work on two identical machines at work using identical coolant but one tank turns bluish green after a while of not changing it and the other one thickens from white to like a thick Tanish color? Anyone know why they are turning 2 different colors?
Sir can I know what are the problems are employed both machine and job/tool by using this kind of coolant (oiled coolant) pls explain me sir please,..........🙏🙏🙏🙏🙏
Its so smart and simpl
Ever since we switched to a fully synthetic coolant, never had a bad smell come from it, even when it is very used. Still have a tramp oil problem, but the bosses think changing coolant or getting a skimmer is too costly.
skimmer is the best!!!
Why didnt Mark from " tip of the day" do this video?
3:41 "Spray Bottle" what are they using in it to clean the surface of the tank?
who do you give the bad coolant to?
I machine nothing but platinum at work, you should see our sludge 😉
Haas can you tell us, what can we do with the dirty coolant? Is there a safe place to throw it without polluting the environment?
Hi d3mandd - This is a very good question without a simple answer. The first place to look for information about disposing of your dirty coolant is to check with the Federal, State, and Local authorities in your area. Depending on where you’re located, the laws can vary regarding what is classified as a hazardous material and what is not.
Waste coolant/cutting fluid should never be disposed of into a storm drain, the sewer, a septic tank system, the ground, or any other non-approved location.
A good source of disposal information can be your coolant supplier or manufacturer. They may have guidelines for how to dispose of your particular waste coolant in the most efficient manner.
Another place to start would be to contact licensed waste haulers in your area; they should be able to tell you how to deal with your waste coolant.
The EPA web page below provides links related to solid and hazardous waste within the U.S., broken down by state and then by territory. An online search for “disposal of waste metalworking fluid” and other similar searches can also yield useful results.

Could you give me a few more specifics as to a recommended High Alkaline Cleaner? Thanks
Hi Richard Giess - Thanks for your question and interest! There are a variety of these high alkaline cleaners available on the market. It is best to choose one that is formulated specifically for cleaning machine tool sumps. In the rare instances when we’ve needed to clean a dirty coolant system, we obtain high alkaline cleaner from our local Castrol metalworking fluid vendor.
It is probably best to start by contacting your coolant supplier to see if they can provide or recommend a particular product. You can also search online using the terms “machine tool sump and system cleaner” or “alkaline cleaners for machine tools." Hope this helps!
Could you be more specific and tell us which cleaner you used.
local distributers like Grainger have Zep Heavy-Duty Alkaline Cleaner
Would a dilute mixture of Ammonia work ?
Also, a brand name for the Oil absorbent rags you show would be nice.
Pig oil absorbent rags, whamex xt for cleaner
oh wow..
My last job let they're screw machines tanks get so bad that people were breaking out because of the bacteria. So they put out hand sanitizer. I don't work there anymore
There's gotta be a better way! I'm not doing that anymore crawling on the floor shovel tanks. The big machines are a nightmare. Why can't you design the conveyor to catch oil and sludge and dump it in chip bin
Look up sump sucker.. big BIG vacuum that is specifically designed to suck up coolant, chips and sludge. Just need a drum or tote to discharge it in then clean tanks and rinse system well.
Spoiler alert there's stuff for that already (i mean probably from the 80's), but usually optional even on high end machines . The chip accumulation is what it is , some conveyors and tanks accumulate less , some more .
Six urinal cakes full stream for 1/2 hour tip out jet wash refill easy
I can't stand cleaning coolant tanks. there's always a layer of chips and sludge at the bottom. and it smells.
How often were they cleaned? If them smelled I bet you're not cleaning them often enough, you're not using DI water, or you're keeping used up coolant.
My work neglects cleaning our machine extremely. What can that bacteria cause? illness or skin problems????
Do you breathe oil mist?
And if you do?
Both. Symptoms like sneezing, coughing, headache,severe sore throat. Right now I'm having headache and sore throat from breathing the oil mist. Maintenance guys don't care about it!
Oil mist, transmission fluid mist, coolent mist (jcut) and the machines are rusty as hell so probably some rust also.
What is the correct parameter of coolant - pH, and hardness?
Hello Andriy, Good question. We cover proper pH and hardness levels in our "Tools of Coolant" video. Here is a link to that particular section of the video. ua-cam.com/video/itQOP_JjilM/v-deo.html
Here you'll find that we recommend pH readings between 8.0-10.0 ( on the alkaline side) and hardness levels between 150-400 ppm.
Note though that many modern coolant concentrates are capable of functioning well at hardness levels above 400 ppm, so if your coolant is not exhibiting signs of corrosion or bacterial infection then there is no reason to replace that particular batch of coolant. Just test your coolant regularly to ensure it's chemistry is not suddenly changing for the worse.
Thanks for the question.
Thank you.
What difference does it make to operator, machine, or machining process whether there are bacterias in coolant or not?
Hi Zbigniew Śliwa - Great question! When your coolant is kept clean and the proper concentration levels are maintained, the chances of severe bacterial contamination remain low.
If proper maintenance is not sustained, it can lead to bacteria contaminating your tank and coolant plumbing.
The bacteria have a number of negative effects:
They eat the soluble oils that provide the lubricating characteristics of the coolant. Sooner or later this can effect cutting tool operation and surface finishes. Generally these oils also provide the corrosion protection for your parts, and as they are depleted so is the coolant’s ability to protect your parts from rusting.
If you begin to smell an obnoxious odor coming from your tank then it is likely that bacteria have taken hold of the tank and are emitting sulfurous gases as they digest the tank’s contents.
Finally, once a bacterial infection has taken over your tank, you may experience skin infections as you handle the parts and tools that come in contact with the coolant.
All of this hassle is unnecessary and can be avoided if you properly maintain your coolant.

I was not aware. Thank you very much.
It can also have a personal toll. About 7 years ago i worked on a horizonatal mill that had a worn sheild. It would let coolant spray on the operator during fixture swaps or when the coolant through sprayed just right. I got coolant sparayed on my face and i apparently had an abrasion or cut that it found. My face had got a staph infection and my left eye was completely swollen shut.I was nearly iunrecognizable for a week. I still have a large "bag" under my left eye froom the skin that never shrank back to it's original condition. Don't let your foreman or leadman pressure you into keeping production up at your own personal risk.The Doctor said i could have died with that big of an infection so close to my brain. I have also had staph infections in finger cuts that swelled so much the skin started splitting. I think the cnc machine manufacturers should incorporate Ultraviolet lights to head off the bacterial growth that is almost nearly certain, and employers don't alot the time for tank cleaning, not do they like dumping coolant. All it takes is a sneeze or cough for the process to start.
@@kenmoll2896 That's terrible! Those coolants should have mandatory biocide in them! Unfortunately UV-C would most likely break down and damage the oils long term.
Je n'ai pas
Have you tried to let a piece of copper in the tank ?
It kills bacteria.
A better way of using copper for its murderous proclivities towards bacteria and scum would be to electroplate the whole tank, first in zinc as copper doesnt take on steel directly through electrolysis, but does onto pre-plated zinc and other more friendly metals on the chart of electronegativity of elements... That said, yeah, richly copper plating the whole inside of the tank would not make it sterile, as chips landing in there would provide area that is not copper plated for scum to thrive in, but it surely would benefit the whole system... Also, copper plating the whole thing, inside and out would provide a much cleaner surface, along with oxidizing lovely over time to that classical copper green, while preventing rust and bacterial thriving... A fine idea, fine sir...
@@camillosteuss
Paint the whole tank with marine hull red paint.
It's made to avoid marine growth on the hulls ,there is copper particles in it.
I don't know if it's compatible with cutting oils ,so it needs to be checked.
Dumping some copper tubing donuts a bit every where should do it i guess.
It's not like if they can't cut copper pipes in pieces in those workplaces lol.
Dont have time for all that extra stuff. Just clean the tank and fill it where I work.
So, why don't you include installation, that scoops the chips, whippes the oil off the surface, deionize tap water, fills coolant, kill bacteria and monitors all the process, to call a warning for maintenance?
Like my Job dude
Here is an industrial tool that reduces the machine cleanout time up to 75% and keeps the operator away from the chips and coolant: ua-cam.com/video/kDRiVk105xc/v-deo.html
or you can get synthetic coolant and avoid this headache....
