TRICO MD-1200

[cpworkshop]

Greeting All,
I recently purchased a Trico MD-1200 mist system. The coolant here (Melbourne, Australia) which is recommended by Trico is VERY expensive. Does anybody know if alternatives can be used like WD 40 or even kerosene. I regularly use WD 40 or kerosene when milling aluminum at work. Would this damage the internals of the WD-1200?

Many thanks for any replies.
Cheers,
Chris

It might be expensive, but it barely uses any quantity of lube either.

Maybe try some kind of a vegetable oil, since one of the oils they (Trico) offer is vegetable base. Vegetable oils do tend to oxidize over time, which will plug the nozzle. But with a small drill, you can clean the nozzle ocassionally by hand.

As for your question about harming the system with other chemicals, it is basically a venturi siphon, so there is only the tank, the plastic tubing and the nozzle in contact with the lube, so there is not a lot that will go wrong in case you need to replace something. I would stick with the less volatile, light weight lubricants though. You do get quite a lot of air flow, and you don't need nor want a lot of stink in the area you are working.

Hi Hungflungdung,
Thanks very much for the reply. I have never used any vegetable oil throughout my machining career. All my oils have been petroleum (sulphur) based. Most of the oils referred to in this forum are easily purchased in the U.S, but not here. I will do a google to try and find a vege based oil. Thanks again.

Regards,
Chris

Hi
I use a mist system on my lathe and to be honest it is the same Sapon general purpose coolant, I used when I tried using Flood cooling.
I just found Flood tooo messy for my needs.
When not using mist I often use WD40 by brush, it stinks and it fumes really badly when it gets hot. No way would I think about using it in the mister.
The Sapon works really well for Aluminium or steel.
I am in Melbourne so you should be able to get the Sapon coolant. Let me know if you have a problem and I can get more details, where are you?

Hi Nigel,
Thanks for the reply. I already use Sapon A for flood coolant on my lathes and milling machines. This stuff generally tends to go off over time and stinks. It also tends to settle in tanks and gum up. After doing some more research I am going to run INOX. I already use it for tapping, screwcutting etc. and its a great anti corrosion. It dosen't smoke either like WD-40 when hot. Can even be used on food grade manufacturing.
Cheers,
Chris

Hi Chris
I agree with you about all the downsides of flood coolant, which is why I went to mist.
The benefit is that you always use Fresh coolant and there is very little mess. I think it must evaporate.
It still contributes to cooling and lubrication. I would not bother using anything else.
Inox is good stuff, only ever used it as preservative/lubricant.

Hi Nigel,
Out of curiousity, where do you work?

Cheers,

Croydon
2 small cnc lathes (100mm chuck) and a larger centre lathe (160mm chuck)

Had to make up more coolant today and it is Sapon GM that I use.
As I said before, didn't like it much as flood coolant but works great as a mist on both Aluminium and steel. I use a Noga mister (the deburring tool company).
Is the Trico MD-1200 a mister or a droplet design. The Noga is mist only and getting a very fine (invisible) spray can be a bit of a challenge at times. But even when the mist is visible, the lathe stays reasonably dry. Just needs a bit of a wipe down, certainl not coolant all over the place.

Hi Nigel,
The MD-1200 is a mister, well atomiser really. I haven't actually received it yet as it's coming from the U.S. Should be here sometime this week.

Cheers,

Hi There,

New to the forums but thought i'd post up something

Where I work we run 3 multicam (australian) routers, each had md-1200 trico units on them.. we ran some fuchs econocut or something? used to order it by the drum.

I found the guys used to just dump it on because it was so cheap... when we were machining a 5mm recess into 6061 t651 aluminium plate, we got plenty of smoke. I've since learnt that we are cutting too slow, and putting on too much oil...

In order to combat this we ended up putting in a Trico unit, running their vegetable oil and we have had very very good results, with only a little bit of smoke, but i've found that if i turn the oil down for the machining when we're cutting the profile i'm getting too much heat in the cut..

Hi Glenaux,
Thanks for the reply. I too run an Australian Multicam from home as part of a weekend business. I have a full engineering workshop set up in my garage for one off prototypes. Where do you work? Are you in Melbourne? What type of parts do you produce? Do you personally run the multicams? What year are your machines? Sorry about all the questions but its great to hear from somebody who has the same machines as me since there is not a lot of information on the web about them. What diameter cutter are you using for aluminuim? What feedrate for that cutter. I haven't got or fitted the Trico unit yet as it's still coming from the U.S. In future would you mind if I picked your brains with any questions with the Multicams?
Thanks very much,
Regards,
Chris
