How to turn on high oressure coolant in Mazatrol prog VTC250D/50 with a Mazatrol Matr

Turn on high pressure coolant in Mazatrol prog VTC250D/50 Mazatrol Matrix Nexus 2

Hi folks.

Machine is equipped with high pressure coolant and has never been used. I know M131 turns it on and is regulated with (I think M103-M107). Trying to make it come on in a Mazatrol prog and nothing seems to be happening. Does it have an external power supply that I am missing? There is a ball valve between two stand up filters. Safe to assume that just switches between the two filters? Many thanks!

Was trying to edit the title when I accidentally hit send. It is a Nexus 2 controller

Press the MDI key, use keyboard to type "M131" (without quotes) then enter, then Green button, should turn on whatever is enabled with M131. Look at your command screen to see if M131 is on. Perhaps you need to use the other 'regulating m codes' with M131.

Thank you Red!

Did exactly as you describe. Simply turning on M131 did nothing. I added M100 (lowest pressure 300psi) and also tried M106 (highest pressure 1000 psi) and got what looked like normal coolant flow (no difference between the low and high and what I normally see when using through spindle coolant. I added M51 (through spindle coolant). I was completely underwhelmed. My expectation was a lot higher, expecting "high pressure". I think I am still missing something. I am not seeing/feeling/hearing anything coming from the stand alone high pressure coolant unit. Thank you for your time. Very much appreciated.

If the high pressure pump is a Superflow unit and it's never been used, it isn't primed. There should be a big yellow button on the front of the unit, hit that, then try to M131 M106 in MDI. If it's hooked up correctly you will know if it's running, they are normally pretty loud. It may require priming several times to get all the air out of the system. There should also be a feeder pump on the tank that pumps coolant into the superflow, make sure that is coming on as well.

Thank you Hacker!

I do believe that it's a Superflow, and I've seen the button you talk about. I'm back to work on Monday and will take another look. Thank you for your time!

Here are some pics of the unit. I'm not noticing anything different from an M51. I can feel the unit rumbling, like it's doing something, but nothing that indicates "high pressure". The shop is kind of noisy but I can hear it humming if I get close to it. Nothing out of the ordinary happens (looks just like an M51 has been activated)when I hit the yellow button then M131, M106. How much time do I have between hitting the yellow button and inputting the MDI? Takes me a few seconds to get back to the key board. I do see a hose coming from the coolant supply and I can see pressures in the gauges connected to the filters. I've tried throwing the valve between the filters back and forth. One way reads slightly higher than the other, (maybe a 40 psi difference?)

Are you doing M131 M106 on one line? If the M106 is on a second line I don't think it'll work and it would be at the lowest pressure I believe.

Hiya Hacker.

I *was* putting it on two lines, as Red suggested above. I tried putting it on one line and I get the same thing. Still looks and acts like I've simply turned on M51.

There's a pressure gauge on the unit below the yellow button (see pic above) that reads zero in all phases of my tests. It reads from zero to 2000 as though that should register the pressure that I command (M100= 300psi, M106=1200psi) any thoughts?

I had a guy stand by the switch on the unit as I commanded the M131 M106 and he confirmed that it "clicked".

Mark

Hmm, yes the gage below the priming button is output pressure. It should have a reading on it. One thing to check, under the two filters there are ball valves for draining. Make sure they are both set to closed. If they are open it might not be building up any pressure.

OK, haven't seen those. Will take a look! If I am anything, it's persistent! LOL I appreciate your help and patience!

Mark

What does it do when you put your m131 in a simple OD turn program? If it alarms out your machine doesnt have the high pressure option m51 takes its place. It's just like air through you can have the buttons and mdi it but it's an option when you first buy machine that Mazak doesnt download to controls its does nothing. Also m104 is lowest m105 medium m106 is high those are m-codes after you put your m131 in your unit that your running.

I appreciate your thoughts Pete.

First off, it's a mill. I'm guessing that the commands are the same for the lathe. As mentioned in my original posts, nothing much different happens if I use just an M51 (thru spindle) or M131 (high pressure) with M100 (lowest) or M107 (highest). They appear to me, to be the same pressure. Not what I would call high pressure. The gauge on the high pressure "box" does not move when activated. I can feel the box humming, like something is working. The valves mentioned in the last post by CNC Hacker are closed.

Mark

Mark, I forgot to mention, the pressure is related to the size of the coolant orifice that it's pushing through. So if you're just running out the spindle of the machine with no tool loaded you might not see a pressure difference. Try loading a TSC drill or something if you haven't already. If you do that and it still doesn't seem to be building pressure you'll probably have to have a mazak tech come out, cuz it sounds like you're doing everything right and I'm out of ideas

Hi Hacker!

Sorry for the late response. Seems the only time I remember to respond is when I am not near a computer LOL

I had that feeling, so I did use a TSC tool. An indexable drill. <shrug> I'll try to remember to bring it up to the next tech that comes to work on something. Phone tech help has been sorely lacking.

Thanks again for your time and efforts!

Mark

Well, It's still a freakin mystery LOL

Mazak guy was visiting to fix a carousel dropping tool issue and I asked him to look at the HP coolant, too. Of course, he got to that part while I was off, and no one left word for me as to what the issue was. The gist I got was that "it wasn't hooked up properly from the factory". All said and done, it's working as it should. wow. If the spindle ever quits, we can use it as a water jet LOL

Thank you very much for all of your efforts and input!

Hello again folks!

This high pressure coolant is going to make me crazy! Now that it’s working as it should, I am having trouble within a program. Beat my head against the wall and can not see it for the life of me. Hoping one of you experts can spot the error.

Basically, the problem is that I have a through spindle coolant 82 degree indexable cutter and the profile of the insert creates long stringy chips that find their way into the coolant passages. I have tried an entire spectrum of feeds/speeds to cause that to not happen and to break the chip. I *was* using TSC (M51) My thought was to try the HP to maybe keep the chip out.
So I simply added M131 and M106 (on the same line and on different lines) with and without the M51. When that tool is called up, the HP does not come on. It *does* come on for the NEXT tool, which doesn’t have or need TSC.

So I thought I’d include my program to see what you think. My apologies for not having the lines numbered. I wanted you to see it as I wrote it without cleaning it up. Wondering if lack of line numbers could be part of the problem. I *did* remove any proprietary info.
I’ll add line numbers if it’ll make it easier to refer to things.

Without this M09 here, TSC works for all remaining tools, which they don’t need.

I always prefer to switch off coolant with an M9 if I'm gonna change which coolant mode to use. Otherwise it tends to stay on like you're seeing. M9 will stop all coolant, flood or high pressure.

Also you shouldn't need to do M51 and M131 M106 together. M51 thru-spindle is running off a different pump normally, since it's lower pressure.

Thanks Hacker!

I'll take another look, but I'm pretty sure that I tried every conceivable combination of commands and couldn't get it to come on for my 82 degree and off for everything else. One thing I think I missed was turning the coolant off with an M09 on the previous tool.

I appreciate your time!
