HAAS 8-Station Pallet Pool - Kremin CNC Reviews

In this video, Trevor from Kremin Inc. shows you an in-depth look at their HAAS Pallet Pool they purchased for their HAAS UMC 500. The 8-Station Pallet Pool was the right addition for the project, but not without it's drawbacks.

I found your video well after buying a VF2SSYT +3 pallet pool and fighting shavings under the table at pallet change.

We found a work-around by removing one pallet and calling it into the machine at the end of each program....running a thru-spindle coolant/fan cycle around the table and using fan to dry it off as well. That took our failures from about close to 100% to under 5%. We also probe each pallet before running the cycle. If there's a chip under my table, I know and it stops (or moves to next scheduled and tests it.)

We did demand the problem be resolved before making payments and HAAS Factory actually did a software update which allowed us to select "Pallet-zero" or basically empty the machine with an M-code that replaces M199. This ends the program/empties the table/runs our chip wash cycle, and then moves on to the next scheduled pallet if another pallet is scheduled to run.

At this point we would consider purchasing another rig just like the current setup.

You might want to inquire with Haas about this, as it was done in an official update.

Good Luck

We always run a cleaning program on our automated machines it also is a lot nicer to load aun unload parts that are free of chips and you hardly ever have to spend time cleaning the palletpool

Add a wash down nozzle to clear chips under the pallet.

Thanks for the review, very informative. Have been looking at exactly this setup, and it's good to know about those issues ahead of time.

Haas isn't the only one that has issues with the chip problem under the pallet, I've run Doosans and DMGs that also had it, and the 5 axis machines are the worst offenders. Nature of the machine. If you're running a pallet changer lights out, you should be running a washdown cycle every pallet change. It's just good practice, period. You're lucky enough to be able to write your own subprogram with a haas and easily call it with an alias M code. Most chip fans nowadays allow through spindle coolant so you can wash down and then blow off all in one tool. Rotate B axis all the way to one side, rotate C two or three times with coolant blasting, rapid B axis to other full extent, make a couple passes with chip fan and c axis rewinding to 0 then done. As others have said, reliability is the main goal of lights out, not absolute speed.

Does the machine also have air plumbed through the table? If so, you could rig up a series of air nozzles below the pallet to blow any chips or contaminates out of the way of the locating pins/clamp cylinder, and you could tie the air blow off function to a spare M code in the control that could be output when you post your code, or integrated into the pallet scheduling. I have seen some brands of horizontal machines have this same set-up, but it is obviously a different beast.

This is good to know. Thank you for the information.

For dealing with the chips, consider a spindle chip fan

[metaltradesolutionsllc]

What brand of vise is on the two pyramids in the pallet pool? They don't look familiar to me.

Thank you for another great and informative video! I like a couple of the solutions people posted and was brainstorming a little. Then I realized that there are too many unknowns for me to be useful at this time. I'm glad I watched the beginning again because at first I thought that you had installed it yourself and I didn't catch any sarcasm in the cute little clip the first time. lol

Can you clean the pallet while the changer is doing it's very slow pallet swap on it's own enclosure side (putting down pallet 1, turning, picking up pallet 2?). I can't imagine the 20 seconds or so this takes wouldn't be enough time to change out to a chip fan, cover the pallet locks in flood coolant, and blow it off.

[inuyashacoolieo]

While I agree that they should add some kind of air purge under the pallet to clear chips, even if it adds 2min to your cycle that's really not much. You said you want to get 20hrs of unmanned operation out of the cell so that's about 2.5hrs of time per pallet. You only have 8 pallets so assuming it's 2min to change + 2 min of wash down, you're only losing 32 min to changeovers over the entire run. That's only about .03% of your total cycle time so pretty good in your case. The whole point of automation and running lights out is that you don't have to pay someone to stand in front of the machine. So, what's a couple extra minutes to guarantee peace of mind?

[jasongreenawalt]

We have to wash down under our pallets every cycle or have the same problem

[jasonruch]

I guess your machine needs a whole lot of memory to run a system like that?

Keep telling the truth and documenting the problems.
