HAAS TM2P tool changing ERROR

[rally210er]

Hello all,

the service in my area can not help with my problem, delirious filling up their pocket with money.
So I hope for help in this forum.

Maschine TM2-P
tool changer tenfold

Error description:
- tool change in program
- Machine goes to Z-position to put off the tool
- tool changer drives in from the left to the end stop
- tool is placed to the tool changer psoition perfectly
- machine activates the ventiles and gives free the tool
- lower tool- release sensor gets switched, ventiles switch perfectly
- machine moves up above the tools in Z-axis
- tool changer spinnes o the new tool (tool release is still on)
- machine goes down in z-axis do clamp the new tool (tool release is still on)
- machine stays still and waiting for clamping the new tool, but the ventil does not switch of
- 5 seconds later, red lamp and error
- 8-12sec later the tool gets clamped perfectly
- Error must be rectified manual (Recovery)

Randinfos:
Details:
- doesn’t matter witch tool place
- sensors above the spindle are working very good
- sensors are adjusted perfectly
-all axis sensors are cleaned, also the indicators

What can I do to make it work again smoothly?
It happens every or every second tool change, and we cannot work with the machine anymore.
Do we have to teach the tool exchange position?
How can we do this?
Is it possible that a ventile does not work smoothly and sticks?
The machine is working with clean and dry air.

Tnx for your help and response

Hi together,

I had some ideas and have been to the company

What I have done:
- Made a program with 25 tool changes
- The machine was running smoothly damn…
- Cleaning the whole tool changer
- Checking all tool changer sensors

- What I didn’d do:
- Rotating the spindel between the tool changes

- Two questions:

- tue the tool change there ist he spindel fixed
- Could it be, that the spindel tilt is too big during the change?

- I have made some videos and fotos. Is there somebody who can see something that is not in regular conditions?

Sounds like the 2 air valves that are above the spindle are not working correct, take the muffler from the top valve and see if it gets working as it should, these valves get messed up from dirty air ( water mostly ) you need a good air filter right at your machine and one at your compressor, also coolant mist gets sucked up by the fan on top of the spindle housing, you need to remove this and clean everything, so if you are using coolant there will be a gummy mess up and around the 2 air valves wiring connectors Etc, the top valve is only a $30 valve the large 3/8 valve I don't know but the cost would not be very much either, the manufacture of the valves there name is mac

Top Valve complete mac 11B-421BAAA

Just the body part # 1111A-000

Muffler are just a standard

The drawbar also may need a service also

[rally210er]

do you mean a service for the drawbar=spindle?
there is no air conection.

[mactec54]

do you mean a service for the drawbar=spindle?
there is no air conection.

There is no air connection for the drawbar correct, but you still need to after a few years of use take the drawbar out and service it, by cleaning and replacing any parts that are needed

The air valves and actuator are above the Drawbar, it is all very easy to fix, this is where your problem is

[rally210er]

So I will change the solenoid.
I will not take the MAC ventil, I will take a Festo part.
The original is 220€
The Festo part is a slide valve and the MAC is seat valve, that can stick easyly with bad air.
I toke the following components from Festo:
575566 VUVS-L30-M32C-MD-G18-F8
8030806 VACF-B-B2-16B
539710 MSSD-F-M16

Take the little bronze filters/mufflers off of the solenoids and try a tool change. When they get plugged up it will cause that problem.

The valve at the top is a pilot valve, your valve would have to be the same type, this mac valve from a supplier is les than $30 27.98 euro, you don't need to buy these valves from Haas, any good pneumatic supply store can get you these valves

The Bronze Mufflers cost very little also, $ 2.23 for the small one and $ 4.32 for the large one

Here are some German suppliers that will have or get the Mac valves you need

Thanks for the surpliers I know them.
I asked them for the spareparts, but the delivery time is up to two weeks, the Festo part will be at my site tomorrow.
I will check the mufflers.
Thanks for all the help.

As long as the Festo parts have the same function, then they will be fine, the Festo valve is just as good as a Mac, the mufflers you need to replace these

[rally210er]

It runns smoothly without any issues.
It is also half as loud as the old one was.

The other problems that these give are the quick exhaust valve which is the valve that connects to the bottom of your new valve, this is a $10 to $20 part, that has a rubber piece inside that gets damaged over time, the valve is called a Humphrey Quick Exhaust Valve Part # SQE2 1/4 pipe

You should change this valve if these other parts where failing, motor mounts also make a difference, the coolant and oil damage the rubber over time, you can change these without removing the belt, which you don't want to do unless you need a new belt, as this then would have to be re-synchronize with the Encoder for your spindle positioning for tool change alignment
