Haas TM1 Air supply question.

[Ken_Shea]

Any one know the CFM requirement for the Haas TM1 ATC?

Need to get a small compressor to run the mill while I look for parts to get the regular compressor up and running.


Thanks

I think if you look at the Haas website the recommendation is 4cfm for their machines but I think that is overkill. I have run six machines at the same time on a 12.5 cfm compressor so in a pinch you could probably get by with something as small as 2 to 3 cfm.

Thanks much Geof,
That's good news, and fast too

I don't know the exact number but, I'd say that anything with a tank should work fine to keep it running with occasional toolchanges--one to two horsepower should do it.

Of course, this depends on how many toolchanges you're talking about. If you're running production with a toolchange every minute or so, you'll blow up just about anything not rated for continuous duty. It'll also not keep up with the toolchanger if it's constantly bleeding air every minute or so.

No production Greg, the TM1 has what I believe is a cleaning blast but that does not last long during change.

Thanks

We were all responding at the same time. I figured even a little pancake, nail gun compressor would do it, then I thought about the slow tool-change time on that machine and how long the blast is running. Then I thought about you making dozens of little parts with a short, mill, drill, tap, chamfer cycle. You could see how that could overload a tiny compressor.

I'd have to be on the look out for lots of back to back changes but that doesn't seem to be the norm. Tool changes on a TM1 are actually not that slow, most often referred to as slow but that is due to the factory defaults of the built in 10 second delay, which has long since been changed to none or comparing them to to those ultra fast changers, then, it is slow by comparison.

A guy could test one of the small compressors with an air nozzle, pressure the compressor up till it shuts off, open the air nozzle full blast and count the seconds till it kicks on or pressure drops to 85 psi or less.
May try and borrow one of those 1 1/2-2hp units with a 13 gallon tank first.

Ken-

We ran our TM-2 on a 3HP compressor for a couple months.

I don't mean to hijack the thread, but what is this 10 second delay? I haven't noticed anything of the sort on the TM1 I have here.

On our TM-2P there was a ten second delay and beeping before each tool change and I just figured it was a warning for people using the open machine to get out of the way. It was really annoying and didn't stay that way very long.

Oh. Lame. Our machine is second hand and doesn't do that thankfully. The spindle stop and head retract seem like pretty obvious clues that it's about to change tools. Not that I would stick my head/hands/feet anywhere near it while it's running!

Upping the rapid speeds to 400IPM also made a HUGE difference in tool change speeds. After using 400IPM rapids for awhile, the default 200IPM seems ridiculously slow.

Thanks for the reminder, not sure why I have not done that yet, bumped the RPM up quite some time ago.
