Your machine is cold?

[Delw]

Has anyone ever recieved this pop up on there machines?
I came into the shop today to modify a bracket for the kids tvs they got for Christmas.
turned on the machine and called up my warm up program, hit the start button and that pop-up popped up. I don't recall seeing it before. is there a thermostat on the machine? the machine ran Christmas eve till about 3:30pm, was off Christmas day.
Its actually pretty cool, even though I run the warm-up every morning, I just never noticed it.

It is a time and/or temperature thing.

If the machine has not run for several days you will get the warning to run a Warm Up programe, or if the machine goes below a certain temperature, something around 50F you will get it.

During the summer I can go for weeks without seeing it but in the winter it pops up every time I power up the machine and press cycle start.

This is a good thing that HAAS put in their machines. It prevents damage and increases the machines life.

One more reason to buy a HAAS machine.

Thanks geof, its been a little cool down here lately at night, Ive had the machine off before for 30+hours but havent ran it in the cold before as I got it in the late summer.
I was just curious how it worked.

I was trying to hook up Tvs in the kids rooms and the mount santa brought wasnt sufficient and would requiere a different location into the wall rerouting cable and electrical. would have been easier to goto the store and buy one, but my little girl (9)told me to goto the shop and make one and showed me how it should work on the existing mounts. " Yeah dad (agreeing with mom) its just two little brackets shouldn't take you but a hour or so" Damn they make it look so simple but theres always something that can be made better then org. planned.

Toby Agreed, what I would really like to see HAAS do is put the warm up program for the spindle on a button( marco) so you just hit the "Warm-up" button and your done with it.
have it right next to the reset button. this way you just hit a button after the machine goes to home.

That is a good idea. I have 3 different Warm Programs for both Lathes and Mills.

Identified from Old to New. I modify them according to what a shop has on their floor.

It is never good to run spindles, ball screws, and ways while they are frozen.

There are usually ignorant comments like "your too scientific" and I just laugh.

LOL, I always manage to make more good parts than the rest but they have not figured out why yet.

It takes all but 3 seconds to hit "list program" "end" "warm up" "current commands" "cycle start". Plus you only do it once a day.

[Delw]

Actually its takes a little longer then 3seconds your way.

if your in edit mode and type in O02020(my program number for warm up) hit cursor down it takes less than 3 seconds

There a reason why I mentioned a button its so people dont forget,. there could be a parameter built in that you can turn off if you for some reason dont want to run the warm up program.
Obviously there are things that would have to be taken into account and thats why it was probably not done via haas, like big tools for example would suck for someone to have the wrong tool in and have it crank up to 10k rpms during warm-up

Yep; which is one of the reasons I edited the warm up program on my 15,000 rpm spindle machines. An unbalanced tool at 10,000 rpm makes a funny droning sound but is not likely to damage anything in only a couple of minutes running, at 15,000 I worry that the bearings will get toasted.

I worked in a shop that ran the Spindle at 15k for 30 minutes every morning with tool 1 in the spindle, a 3 inch shell mill. LOL, I mentioned that was a bad idea, got dirty looks, nasty comments, and ignorance. They had to replace the spindle bearings after 18 months.

Start at 500rpm and kick it up 300 rpm every 2 minutes while moving the XY at 20IPM full table travel with 5 inch radii in the corners. when you start getting up around 2500 rpm, cycle back down to 500.

15 minutes from when the shop foreman does the morning start up. Your good to go all day.

If you are running the Haas Warm-Up program every day you don't need to cycle the speed up and down.

However, if the machine is not used for two or more weeks, and especially if it is cold, then you should run the Haas Run-In program. This one does cycle the higher speeds to guard against overheating the bearings. In addition for the Run-In the spindle bearing purge air pressure should be boosted up to about 30 psi from the normal 18.

I can attest to the need to do the Run-In correctly. My GR510 has a 15,000rpm spindle and after it was installed it was not used for several weeks. Then I ran the Warm-Up and the spindle housing finished up too hot to touch. After a panicky phone call to Haas I knew the correct procedure; use the Run-In program with the air pressure boosted, monitor the spindle housing temperature and if it gets warm to the touch Reset and start the program again.

Our machines run 24/6 and it will come on sometimes after the machine has been running for days. I just chalk it up to a glich. We do have warmup programs on each machine and we will run them after a day of sitting. They have XYZ axis moves as well as the spindle. The lathe since it grows .006" (wonderful HAAS SL20) always runs this warm up cycle unless it is actually making a part.
