Best coolant

[machinist39]

I am looking for feedback on CNC machining coolants, we are currently using Hangsterfer's S-500 CF US., but we are in need of more coolant, so we are exploring the other coolants that people may use and if they suit our needs, we machine Stainless Steel, Mild Steel, Aluminum, Brass, Copper and alot of different plastics from Acetal to PVC. This current coolant leaves thick residue on the machines and on the parts if not washed off right away. We keep the refractometer setting from 7 to 9 as per our sales rep suggested. Any suggestions are welcome. Thanks.

I'm a big fan of Blaser Swisslube. Doesn't stink(actually has a nice smell to it, if you take care of it), going on 2 years in 3 seperate sumps, one of them rather large with lots of compartments. Went from 2000 to 4000 series and saw a decent jump in tool life. No rust, no funny things floating in it. If there is a problem, support is available. Good stuff.

I'm with bubba, we use Blaser 4000 series, we cut everything from stainless, aluminum, brass, hastelloy, p.v.c. etc....no problems with stink or skin irritation......Good stuff!

BTW this topic must have half dozen threads on this forum in the last couple years, please do a search.

I did a search for this information DareBee, I was just checking for any new coolants that machine shops are using at this present time, I have been visited by several sales reps recently that are telling me what I should use and frankly I was hoping to hear it from someone who has used a coolant recently that they seem to like.
Thank you for time and comments!!!!!!!!!!!!!!!!

I know I have a tendency to skip threads that are repeats especially when I have participated in them in the past, others may feel the same way.

I`ve used several types as well and Last year tried liquid ice. It`s clear 100% synthetic biodegradable no odor.Tramp oils seperate from it great on all applications . Made in Mathews, NC. $95.00 for 5 gallon pail mixes 3% on refractometer. Look up liquid ice on the net. Causes no skin irration problems.

Sort of feel the same way so in this case I did a search as an experiment; 'best coolant' gave 500 hits and the thread or post titles did not really give a good indication of what the content was. I sympathise with someone trying to find some information from past posts and finding they have to dig through 20 pages of information.

We use cutting oil Motorex Swisslube NX15. It doesn't sink and it works very well with all kind of material. There is no skin irritation

The search function on this board seems to have "looser" restrictions on what it will give you for any given search... It is a VERY tedious process to weave through all the nonrelevant material..

The problem for most newbies (I am one) is that we may not even know the correct search terms. I've often wondered why forum software doesn't automatically compile a glossery of common terms and topics so that those new to an area of interest have a ready made overview. It could also automatically grade threads that include the terms based upon replys and views.

I can recall when one had to haul oneself to the library and use the Dewey decimal system to find stuff - in books that often had to be reserved to get them and this was before there were message boards.

Now, we can go to the computer, on our own time, at any time, day or night and type in even a rudimentary couple of words and find out a lot of stuff about darn near anything.

Part of the DIY process involves searching for information and the learning of HOW to do it. The more you do, the easier it becomes. Sort of like filing only now you have to use god knows who's logic as opposed to your own. Therein lies the challenge.

Sadly however, even with the availability of instant gratification, it isn't instant enough. It has become easier to ask than to look in some instances.

I share the frustration of those who see the same inquiries over and over but also understand how folks not versed in doing research could have a hard time finding stuff.

However, to those in the latter category, I'd simply ask "how did you find this site???" I found it via a protracted Google search. The trick is search refinement which is a learned skill that has to be practiced.

For example, if you google a "power supply", you'll get a myriad of things that are impertinent. If you type in "CNC power supply", different refinement and much more focused.

Interestingly, typing in "power supply CNC" will show somewhat different results than "CNC power supply".

I'd contend that doing a decently focused "industrial coolant" search would provide quite a bit of insight into what's available...

Search refinements such as "grinding coolants", "cutting lubricants", "machining lubricants" would/should also be considered. If at first you don't succeed, try a synonymous name/term.
