Coolant

[Shawn Wentzel- Wenteq Inc]

What do you guys prefer for cutting fluid on aluminum? I am using valenite VNT-700 but had a Master chemical rep come out and says that Valenites stuff will wear out my machines. They said I should use Trim E-206. Thought I would ask people not trying to sell me something.

I am using cimcool 540 currently, for the last 6 weeks, but do not recomend it, I can not stand it. I will be going back to trim, it is hands down the best i used, I did try some rustlick stuff once that was alright to.

[Chris Rizzo]

coolant wear out a machine??? That's a new one. Tell him his voice wears out your ears.

 

We use Blaser 4000, and I swear by it. I've used some cimcool products and hav'nt seen anything work nearly as well as a Blaser product.

The 4000 is a bit overkill for aluminum, but I feel it does minimize galling/smearing when running surface toolpaths on aluminum.

 

I'm certinaly no coolant expert (and no salesman either), just m2c.

We've used trim e206 before.

That's a water soluable if I remember correctly.

No complaints from me.

Currently we have been using Hangsterfers,not sure which style though,but it smells good

I had heard some coolants (mainly all synthetic) can devour the plastic and rubber products-seals, electric cables,chip wipers etc.

Blaser 2000 very nice stuff

This is exactly true!

My company has been using the Castrol Synthetic coolant for a long time and we have had many problems in the past.Switches sticking,seals rotting out,we even have problems with any aluminum fixture that is bolted to steel and ran in the machine for a period of time.

It is like an electrolisis effect happens ans it yes, Rots out the aluminum!

 

I would not suggest using synthetic coolant at all.

Good side of it,it never stinks!

 

Here is an example of aluminum fixture.

Notice the white powdery substance that used to be alum......

We've used VNT-800 for about 5 years and Valcool Turn-Tech for years before that. Tell the guy he's full of sh!t.

 

I also suggest doing a Forum search for 'coolant' because we've had a couple of really informative threads about this subject over the past couple of years.

We just switched to Hangsterfers a month ago. No complaints so far. This stuff is pretty good also , Motorex Swisscool .

 

 

We're also using the Chip Trap and a small drum coalescer to help keep it clean.

We've been using the Castrol stuff since before I got here. Don't have anything last long enough for the kind of problem Brendan is showing though, all short run jobs.

I like the blaser. and yes you might have a problem with it chewing paint off and wilting rubber, but there is a solution. no not liquid, a refractometer.

run concentrations to suit need at time of use. I would recommend 3-5% normally. For more intense situations I'd say 7.5-14%, but be prepared to break the rules and add water to the mix to bring it back down to save the paint job.

[?Mark]

I noticed over the last 2-3 years that when it comes to coolants nobody here seems to be using DuBois 2050 AC.

 

It's quite expensive, but the best coolant by far that we've ever used (oil based).

No rust and skin problems at all. The best part is we clean tanks only every 18-24 months.

I ran Blaser 2000 from 1985 to 2001 and never had a problem with paint. We only switched to Hangsterfers 500 because we moved and have a local distributer. Both products seem to be very simular and still no paint problems. We don't machine much in the way of tough materials or much stainless but both coolents work very well on alum, copper, and steel.

[kinglouie V]

Gary,

 

The only time you would have problems

is if you consistantly run a high concentration

of coolant. I have had to add water to it since dispite their claims of the tritation, water evaporates quickly under use. Good stuff though.

In fact, I prefer it.

[Boris Schatalow]

You should definitly stop using Valenite-VNT-700.

Even when you the the right blend ratio on the refractor meter, this collent will rust your machine from the inside out.

I say this from my own personal experience. I was able to prevent further damage to my machines by switching to Blaser 2000. This coolant has worked the best for me in every sense.

[Tom Szelag]

Maxim VHP here. We run a lot of Aluminum, Ultem, Polycarbonate, some steel. No problems.

[MetalMarvels]

I have been running Blaser 2000SW for a while now. No more red swollen hands or other problems. However, keeping the H2O level up is always a challenge here in Colorado. It usually takes two to three 5-gallon buckets of water a day to keep the coolant at the right mix.

[Bob_Looney]

I ran blazer for years, it left a slim in tank and on machine, switched to hangsterfers and it removed slime from tank and left it on machine. switched to trim e-206 and have no slime anywhere, clean and shiny cnc. coolant has been in cnc for 3 years with just make up. wouldn't switch for anything.

[dott]

I use BlasoCut 2000LF. Sswitched from simi-synth about 2 years ago. I had all kinds of tapping problems in aluminum and salesmen would tell me it was the coolant. I thought they just wanted to sell me coolant. I never believed them until I switched, mainly due to cost of coolant and freight. Running 10% but could go a little lower.

[Tom Szelag]

I should add with the Maxim VHP apparently in the 6 years we've had our Fadal the coolant has only been totally changed out once. No smell, no corrosion (provided its kept at the right mix), no slime, no skin irritation.

 

Like Gary though defin gotta keep adding water to keep it at the right mix with the CO atmosphere.
