New guy makes first $$$ mistake

[RMagnusson]

Well....yeah, so. I'm pretty new to CNC (like 3 months) and while we were setting up our machine I put a bunch of Velocite no. 3 in the coolant reservoir for our Mazak FJV-25. Needless to say that is a SPINDLE cooling oil and not a CUTTING oil/coolant. I just saw 'spindle coolant' in the operating manual and figured, 'Well its coolant, and 20 gal wont fit anywhere else so....'

Due to our combination of accessories we dont even have a large spindle oil tank, jsut a small Precise chiller unit.

Anyways, could someone recommend a good cutting fluid? I would like to get this solved asap and maybe with some input from pro's like yourselves I wont end up in this bind again.

And if anyone has any bright ideas on what to do with a ton of Velocite #3, I'm all ears...


Thanks for reading,

We used Valenite VNT700. No smell problems ever experienced.

The stuff is water soluble and suitable for grinding or cutting depending on concentration. Real good at NOT rusting and we have a lot of uncoated steel and iron stuff and even in summer when it is hot/humid and stuff rusts if you look at it funny, it protects.

You can get it dyed blue or dye free. The "700" changes to something else in dyed vs non dyed. W or W/o dye doesn't seem to affect performance.

The Velocite oil can be used for light way oil or even anti rust inhibitor. Frankly, Dexron ATF works better and is cheaper as an antirust inhibitor. We usee a mix of Velocite (1 & 3 I think) in our grinder and went to Dexron instead.

When in danger when in doubt, surplus whatever can be sold for SOME sort of price on EBAY.

Ok, cool. We do have an old Mazak Harley tool cutter/grinder.

We will be doing mostly aluminum parts, sounds like we can just use the velocite to wash them to keep 'em rust free before shipping?

My boss is still probably gonna me, but if we can use it for something then I'm a little less busted.

Thanks again.

i rather doubt that your aluminum pieces will rust before shipping but that will make sure i guess.

the best way to kept you aluminum from rusting is to hold in the air with an aluminum magnet in the moon lite before you ship

Thats some funny stuff

[RMagnusson]

Lol. I take it aluminum doesnt rust easily..

Did some Google-ing and now know the properties of the material we will be working with....and can hopefully avoid future public displays of ignorance

I guess I'LL just have to bath in the velocite to keep the rust outta my brain.

Rmagnusson thats how we all learn you might have made a mistake but you tried hang in there

You should also think about Houghton "HOCUT 795-B" for your coolant. Never seen it get any smell at all.

[RMagnusson]

Thanks Lakeside. Its not really that bad, my boss is pretty cool. The velocite really cleaned the crap outta the lines and pump though, haha.

Some Castrol Syntillo 9918 came highly recommended by out consultant friend so thats what we're running. Seems ok I guess.

geeze! who runs a cnc center without knowing ferrous vs non?!

amazing, and congratulations!

I recomend you sell your useless spindle coolant and look into an edition of machinery's handbook! even a very very old copy is very very usefull!

Good luck!

hot tip: iron dosent rust, so i use iron for everything most people use aluminum for.
