Cheap DIY Flood Coolant For The Milling Machine

Main lesson learned for me is that different cooling systems result in different feeds and speeds. Makes sense, though. Thanks!

[@davidrule1335]

Good video, I like how you pointed out the inherent problems with the mist coolant systems and breathing it. For me chip evacuation is the problem especially with smaller end mills in deeper pockets. I use compressed air for chip evacuation and an occasional squirt from a spray bottle for lubrication. A cardboard shield will stop the hot chips from hitting you. My air compressors are set outside the building for noise and cooling.

[@DavidHerscher]

Im currently experimenting cooling systems myself. I'm using mist at the moment, but as you mentioned, the compressed air situation is less than awesome and I've got a pump system that will be replacing mist on at least the mill, and likely the lathe as well. As note on coolants, in my humble experience, the water soluble synthetics are just no good. They seem to want to cause rust. I bit the bullet and bought one of the oil based emulsion coolants and it's fantastic. Still mixes with water, but once the water evaporates the oil base stays behind and leaves a nice protective film on the machine. I've seen no rust with the oil emulsion, and at this point would run dry rather than put a water based soluble on the machine. The oil based emulsion also lubricates, so im able to take much heavier cuts and get a much better surface finish. Awesome vid, as always!

[@crichtonbruce4329]

I fully agree with your comments on oil based vs. synthetic emulsions. It might be different for those big CNC machining centers that pump gallons of coolant at high pressure, but for us small shop people oil based stuff is better by far.

[@wizrom3046]

Thanks for the tip. 👍🙂

[@densamme1752]

Love your videos, I'm not a machinist but have some knowledge of aquaculture and I have some small cheap tips that might increase the longevity of your pump. A nylon stocking over the pump is a good way to stop grit from wearing out the impeller (cheap ripstop, your grandma will have some). There are cheap and efficient floatswiches that you can mount in tubs to stop the pump from running dry. Most aquaponic/pond shops have them. A rough paintstrainer for the funnel is easier to clean than the metal net in the funnel.

[@brucewilliams6292]

Thanks for the tips. I will use them when I implement my coolant system.

[@jessehesch]

I think the chatter problem you experienced was related to the flood coolant having less lubricity than the oils you previously used. Some water soluble coolants are more grippy than an oil you would brush on, some are not. Usually, the more expensive water soluble coolants have better lubricity. Sometimes you can improve the lubricity by increasing the concentration past what the recommended value is, i.e. 15% versus 7%. Even if you “solve” the chatter problem with higher rpms, you are likely better off increasing the lubricity of the coolant by upping the concentration anyway, as it will result in less tool wear.

[@mrechbreger]

I think it could even have more lubricity for the task, and the mill wasn't rigid enough to push the endmill in. I also get chatter on a mini lathe because the tool prefers to slide until it bites into the material.

[@brenwyattm0rij909]

Looks good Mate. I used a low pressure fuel pump £10, a motor controller £8.50 and a gerry can £12. The gerry can has a small foot-print so doesn't take up a lot of room. The motor controller is mounted in the mill control panel and goes from a dribble to a full gush.

[@yt66228]

Nice project. I went through the same process when I first got into machining. The mess it produced was not worth the trouble. I discovered that using really thick cutting oil was the answer. The honey-like consistency holds the oil in place. Bobs your uncle!

[@GuyMarsdenMakesStuff]

Which cutting oil are you using? I'd like to try a thick oil.

[@crichtonbruce4329]

I built a setup not dissimilar to yours and it worked very well indeed. I used an oil based emulsion though. On aluminum it worked as well or better than kerosene without the horrible smell.

[@rodbutler9864]

I have a similar magnetic set up for my mini lathe but it’s gravity fed by a 2Lt PET bottle that I hook up about a metre over the lathe. I successfully converted my drill press to a light mill so now I’ll move my rig over there as well. Every little bit helps. …luv y’work.

I am setting up an identical system. Identical pond pump (as I had one lying around) in a bucket. I still need to add the strainer before installing it onto the machines. Mine will be a common tank to the mill and lathe. I have 1/4 and 1/2 inch flexy pipes to try, to see which gives the better coolant placement. But previously running with a spray of kero, I was burning up HSS mills like crazy. Changing to a hand oil/water spray dramatically improved tool life. So lookink forward to trying the flood cooling.

[@SouseMouse]

The black tub is good for keeping light out, so that helps avoid algae growth. If this is going to sit unused much of the week you may want to add an aquarium bubbler to keep the coolant oxygenated and suppress anaerobic growth.

This vid has given me food for thought for my mill cheers chap

[@AnthonyHandcock]

It'll be interesting to see if the coolant damages the pump. In my service engineer days I used pond pumps and aquarium pumps with pure kerosene and it 'rotted' them over time. The 'over time' was still long enough that it was a far cheaper alternative to the machine manufacturer's replacement pump if it had been available... Which it usually wasn't. Given their prices and easy availability it's not really an issue as long as you accept that the pump is a consumable.

[@trollforge]

Try a scrapyard for a Diesel fuel pump.

[@Bosbulls]

We used a washing machine drain pump on a large parts washer at one of the places I used to work. That system had a 200lt drum full of kerosene and that pump ran probably 6 hours a day 5 days a week. We cleaned wet brake components for large earthmoving machines. That pump lasted a couple of years and costed in the region of $15.

[@AnthonyHandcock]

@@Bosbulls It's one of those things where you think to yourself "Well... I'm no plasticologist but what's the worst that can happen". Well... That's what I thought anyway. My pond-pump bodge would last about a year and the appallingly badly made genuine article would last a couple of years at over ten times the price.

[@karlmansson8319]

Solder follows the heat. Heat the part from the opposite side from where you are applying the solder and it will flow around. Blasting it straight on will just burn it. Also on the subject of stainless: sharp tools, slow speeds and high pressure is the way to go. Stainless work hardens in an instance so a blunt center drill will create a hard spot in a millisecond if you don't keep pushing it and make chips.

[@artisanmakes]

Yeah I forgot how much i disliked machining stainless, especially 316

[@johncoops6897]

You cannot really solder properly with the part tightly clamped in a dirty great big heatsink (vice)

[@artisanmakes]

Seems to work fine. I don't solder much so the vise has always worked. Plus I have lighting set up for filming the vise so it's easiest for me to use it.

[@karlmansson8319]

@@artisanmakes I mean, it machines fine. You just have to be on your toes and not hesitate. But a carbide spotting drill would probably have helped there. But they’re expensive. I don’t use them personally. Try heating the part from behind sometime though and use plenty of flux with the part on a fire brick instead of in the vise. I think you’ll find that it saves you a lot of work and comes out both cleaner and with a higher chance of actually being water/gas tight.

[@rondonovan4293]

Thanks , you answered my questions as to pump and coolant

[@CanadianPenguin_]

You should add a screen/filter to the funnel or a screen divider in the tank to help protect your pump life. Also it would be easier to clean those screens than pulling out the pump to clean/unclog.

[@glenlivingstonegl]

I was thinking the same thing, maybe a larger diameter 3D printed ring with a fine screen inset thats removable it will sit higher in the funnel when its not running pull the screen and blow out the build up into a trash can and replace it, it's an added laye of protection for the coolant,pump and associated parts

[@David-hm9ic]

Great info! I've had a mist cooling system for a long time but don't use it any more because of the fog. Some of the things in my current shop don't need to be exposed to coolant mist. I had to mill some 1-1/4" (32mm) deep x 5/16" (8mm) wide slots in the past few days and all I had for a lube/coolant was WD-40. It took a whole can to do the job. I was wishing for a drip or low flow flood system the entire time. FWIW, your compressor should be more than big enough for mist coolant. It looked in the early video that you had a LOT of air flow driving the mister, as in far too much. It only takes a little mist to do the job.

[@Justamanonamission77]

This guy never backs down from a challenge!! It's truly good to see someone who tries to make smaller machinery work better. Good job on the workaround! Curious what product you used before coolant? Like what was it and where did you get it? I'm in Canada and would like a spray bottle solution for now.

[@MrCrankyface]

Have you considered adding a small wall/gutter on the outside of your table? Would only add a few millimeters and keep all the coolant on the table. Granted some will still fly around the place when you mill at higher speeds. Also at 15:10 when you're milling steel, if that cut in particular was iffy I suspect it might be because the flow of coolant might be preventing your chips from exiting the cut. My experience when playing around was that the chips get extra sticky with coolant, so you really need to aim the coolant to help the chips move away from the cut direction. That's just my 2 cents anyway, really like your videos.

[@dev-debug]

Cut a circle out of a piece of scotch bright and put in on top of the screen in the funnel. It will capture quite a bit of the small particles that will eventually eat the pump up.

[@HolyDiver22]

The trick with 316 SS is to just push through in one go. It has really good work hardening properties, so it’s quick to harden and dull bits. Make sure you run the HSS drill 100-300 rpm I’ve found.

[@Diego-sz8lo]

Nicely done! In my experience, the coolant should be a little bit more "milky", but maybe I'm wrong who knows. Great little project

[@schrauberhugo2594]

That depends on the kind of coolant: emulsions are milky, solutions are transparent and only light tinted.

[@artisanmakes]

In my limited experience dealing with coolant, emulsified oils tend to look very milky. This is a semi synthetic and it is my first time using it. This could be what it should look like. Granted I am only mixing it at just over 6% concentration.

[@schrauberhugo2594]

@@artisanmakes 6% is really enough when it comes to preventing tool wear. Higher concentration nearly only improves longevity and corrosion prevention. Even pure water gives very good results, but corrosion becomes a problem in the long run.

[@petersgrayson]

I was researching this the other day as I am preparing shopping list to get mill etc and what I want. It's interesting cooling is not so straightforward. Mist is considered iffy, heat cycling is likely. Dry with some of the modern coatings (if feeds etc right) is recommended. Flood is ok, if you ensure flood is done right and actually cooling the bit, chips or even not enough flood can be worse (the flood burns off before it reaches the actual tool). Coating wise if doing aluminium, avoid coatings with aluminium in them. I am planning dry with air for chip removal, I won't be using it often and the flood tank and mess etc is more effort than its probably going save me. Google flood vs none mill there are plenty of good forums with heaps of information that actually convinced me not to bother with flood for what intended diy use I will do. If you look at Tormac systems (there popular on KZbin :) ) or high end cnc videos, they use multi jets with some pressure (not dribble).

[@wizrom3046]

Clever setup! 👍 You could try putting a stainless pot scourer in the trough on your mill table, it will let the coolant drain through but will catch most of the chips keeping them out of the pipes and funnel and the scourer can be removed and rinsed clean in seconds. And yeah, that coolant looks way too dilute... Too watery. How is its lube properties? It should feel really oily and greasy rubbed between your fingers, if it feels watery and your fingers stick then it's a bad lubricant.

For my diy setup I used a 5 gallon parts washer for the tank and pump. They go on sale here in Canada for about $60.00. In the end, I found it easier/cleaner to just use carbide end mills.

You need a oil skimmer , magnet and a much better filter on the intake side of the pump. Experiment with a rubber disk around the base of the vice. Shaped as a shallow cup with a drain tube. This will capture the coolant before it runs on the base. One other thing. With a magnet glued to a clear plastic sheet in front to keep you from getting coolant splashed on you.

According to most trade standards, you can label anything (oil, solvent, reagent etc) that contains more than 30% synthetic main active components fully "synthetic" :) Good work! There SHOULD be something to help lubricate that coolant product, check with the manufacturer.... Also, I'd get a smaller nozzle for the flex head.

You could quite easiely add .35 liter more coolant oil since adding 1 liter to 18 liter giver you little more than 5% 1.35 liter gives you 7%. Also think it looks to clear. Otherwise if you are going to change out the fluid calculate the oil you have to the percentage what you want. So for 7% 1liter/7 then for the water take (1l/7)x93. It becomes like 13.28 liter so 13.5 will set the level a bit under 7%. Also when i worked in a shop we always mixed the coolant in 15l or 30l buckets. Then poured it in the coolant tanks and machines.

Hassle factor: high, Coolant effect for HSS: needed, Mess factor: high, Need to replenish and filter coolant: high, effect on cutting performance: improved a little, Negative effect of water on cast iron: high Conclusion: Use carbide mills and skip the flood coolant. They handle the higher RPM's and heat just fine and you don't need the coolant at all for hobby use. For drilling and tapping, use a little oil. *** I've a got a slightly larger set up than you, but not by much. I use carbide mills exclusively. From time to time I'll put some oil on the mill IF I am machining aluminum since it adheres to carbide. All the rest, I machine it bone dry and my mills either break or I wear them out after many hours of use. *** Hot metal chips, you did solve that problem, but then so do thin leather gloves and a long sleeved shirt!
