Thanks for the comments about my glasses guys. I am somewhat new to wearing them, so the slide is hard to get used to, especially when I sweat with doing my first video work with John. Hopefully some of the content proved useful to you.
We found out lately that coolant is a huge tool and it matters A TON in machining. We have been through many different coolants in our quest to find the best all purpose coolant - 5 in the past 2 years. Our shop of around 80 machines does a large variety of materials, from cast iron and steel to aluminum to exotics and we ended up landing on the Castrol MB50 and couldn't be happier how much better our tool life and finishes are. Great all purpose coolant.
Hey John, TDS DOES NOT represent water hardness. TDS includes everything dissolved in a water, not just solids which contribute to hardness. Nor does the "TDS meter" you showed always give an accurate TDS, as it is based on using conductivity as a coarse proxy. To accurately measure water "hardness", you want to find "Carbonate Hardness" (sometimes incorrectly called "Alkalinity"). You can use a small and cheap titration kit that gives you accuracy to 10ppm. This value is usually half that of TDS. If you are running your shop RO based on TDS, you may be getting a very low Carbonate Hardness a a result, which begins to affect the PH and them cause corrosion issues in your machine and/or parts. My industry is commercial coffee, where water quality is critical but for a different reason! We made a small document for our engineers who work on espresso machines to help understand it if you want a copy. Love the vids as always.
Water hardness is not TDS. TDS is looking at the bigger picture, though both should be looked at together. When we analyze water we look for the anions(chlorides and sulfates) and cations (magnesium, calcium, sodium and others). Contact me at jwiley@qualichem.com if you need some assistance.
I switched to 251C Quali- chem 5 years and it is lights out better then the Sto-cool shit my First Hurco came with. A video this long and they didn't talk about the one vital must in extended coolant life. Coolant circulation and filtering. I can easily get two year out of a coolant fill. Separating out the way oil is also vital. I have 7 CNC machines and the coolant is moving in a circle 24 hours a day. Good water, correct concentration, and circulation and way separation and problems are gone.

I have a hobby lathe and whilst there is a lube pump option, I don't have the space so what I do is mix up water soluble oil into a spray bottle and if the work needs it I squirt or light spray the work. It's a good compromise as I can't make large chips, so heat isn't a big issue, but it helps with the cutting tips. As for water testers, go you to your local aquarium store as they will have dirt cheap water testers. I run a tropical tank and have to test for hardness as I live in a very soft water area and have to add bicarbonate of soda to bring the hardness up.
The noga mist coolers work well with or without coolant. I also have a pressure pump sprayer like some auto body shops use for a solvent wipe. Works well for some MQL but watch out for hot fractures when spraying some cutting tools
Coolant is better for most things and filling a bottle from cnc machine is easy :D Oil just makes so much smoke it is not fun. Also coolant will evaporate from the chip pan and leave a nice fine oil film, unlike oil which makes a mess, especially flying everywhere from the manual machine.
In some countries of Latin America some machinists use something called" taladrina" which is a preparation of very light engine oil,liquid soap,and water ,and it works cooling the work and the tools for cuts when working on lathe or milling machines ,and prevents oxydation of iron when there's leftovers on anything!
What is the coolant recommendation for the occasional use home shop? Mixing a batch for a machine sump that might sit unused for a number of weeks is problematic. Can it be sealed in a container between uses to keep it from going rancid? Interested in what others are doing.
I've been using soluble oil diluted with distilled water for lathe, mill and grinders with no problems growing anything or going smelly. Probably not so cheap for a production CNC environment unless they distilled there own but fine for the quantities I need. 180 litres for well over a year.
Get a good quality coolant, mix it correctly and use RO or DI water, and you should be good to go for many months. If you are in AZ, contact Star Metal Fluids for assistance.
There are some aspects from the first video that I was expecting to see in this one. e.g. how to prepare a cutting fluid for a new machine. What is the right TDS value for coolant? etc
Very informative video. Thanks for sharing. I've just started using a mist system, so this was helpful for me. I'm using a semi-synthetic fluid that's multi purpose and since I have an RO system, I'm using that for my water supply.
On my God! I just enjoyed hearing two people talk about coolant for 20 minutes... What's happening to me..? Oh well, I still liked it. P.S. What metals can snake oil be used with? Will tool life suffer? Sounds like it will...
I just had RO and a water softener installed at my house. Installer said they won't run RO through copper pipes because RO water is slightly acidic and would eat the pipes. Does pH come into play here when using RO water for coolant base? If no factor, I'll just fill some gallons out of my house rather than buying distilled.
So long as the water is mixed with a well designed coolant, the pH is managed by the additives in the coolant concentrate. RO water only gets very slightly acidic, and that really has more to do with the starting pH than the RO process.
Coolant is important because use of the tool creates friction which creates a lot of heat and eventually that heat over hardens the tool material from the produced heat,so therefore it makes the tool very brittle,because that's just what happens when metal is over hardened.
The best coolant for everything is water. Question is what oil mix's with water and is the best lubricant. 50 years of machining experience tells me machine it then protect it. Thanks.
@@wiley635 I did learn, I was just half joking.

Hi Tim, Foaming is due to various reasons: water being very soft, Smaller tank sizes compared to pressure, flow rate of coolant inside machine, Blockage of Pipes, Higher Coolant concentration..
With water hardness, at what point do the TDS cause issues? Like currently I have 310TDS in the well water, what would I shoot for as a balanced number? The softener works to bring it down to about 25, but what about the salt left in the water. Will that cause issues in the first batch as you want some minerals. Also how much of each mineral is a good or bad number to have? Then the RO water I can get has about 4-7 TDS to it, just trying to find a good mix. I cut lots of steel, stainless and aluminum with coolant, but have lots of carry off and issues while welding. Have had a local rep out from Toronto Lube to try some 251 also, but the coolant also has an effect on welding porosity.
Send us a water sample and we will give you some guidance. While water softeners may appear to reduce TDS, the salts used to accomplish the softening might be worse that the water you are starting with...as with most things, the devil is in the details. The cations and anions that exist in your water are the real concern. Contact me at jwiley@qualichem.com to get started.
Hey John couple of questions. Where can you buy QualiChem as a smaller hobby user? I saw you had 55gal drums of the stuff in the shop when i was there for the class but it would take me a decade to go through one of those on my little 18gal sump. Also it would be nice to list out some of the good formulas for multi metal with some of the pro's and cons to each, the qualichem website seems to be lacking with only two case studies and no product data sheets openly accessible.
How about using osmosis to treat your water. you can really get low TDS values I get from 450ppm down to 9ppm. Is there any recommendation for the hobbiest(all materials, prevents corrosion of the machine and parts, and won't go bad if its not used for a long time) which you can get worldwide (in germany)?

I'm using Blaser 735 (the clear stuff) and it leaves a white powder light substance on my ATC door and on tool holders. I use DI water with the coolant. What might be happening?
Cast iron needs good corrosion control. While the tools may not need the performance, the freshly cut metal needs the protection. We suggest running the coolant as you would on any metal. Contact me at jwiley@qualichem.com if you need some help.
I hate suds I can never pick the right one, a rep comes in says this is good we try 5L then buy 25 L then after a couple of months it breaks down leaves oil every where, then wash machine down debug wash try another type and then go down the same road they work fine in a squeezey bottle on the manual machines.
