Haas Question!

[TeccBoxx]

This is a little off topic but wondering for you Haas gurus out thier if you can help me out.

 

We are currently running a program that we have ran numerous times before but without any alarms the spindle turns off and it keeps feeding. We thought maybe it was the program so while I was checking it we popped in another program and it did the exact same thing the spindle stopped and it kept feeding through the rest of the program.

 

We put a new guy on our machine last night and we are thinking he might have changed a setting we don't know about.

 

Does anyone know of a setting or possible fix to this proplem?

 

Anything is greatly appreciated.

I would dry run the program and see what line it is shutting off the spindle.

 

I cant think of anything that would kick the spindle off during a feed move unless commanded.

 

hope someone else has a better answer.

got me stumped!

I recall a Haas do this a few years back.

I think it was a loose board or wire somewhere

 

Id have someone check it out.

 

 

PEACE

My Milltronics did something similar and it kept getting worse...(finished job) and it was a loose wire plug-in.. I went around and tightedned all connections and re plugged all plugs. Plug on Z axis "felt funny" and think that was it.

I had a similar problem where the spindle stopped

then the table would drift till it stopped.

 

It was a while back the Haas dude changed a few

things back there and cleand it out.

 

Periodicaly it would happen again. He removed and

tested boards Etc.

 

He left without a solution.

but

After that 3rd cleaning visit it never happened

again.

 

(He also cleaned servo connections thoroughly the last

visit.)

 

Wierd haas thing.

We have several and I mean several Haas's here. We have had that happen but usually with an alarm with the spindle. The machine should alarm out if its in a cutting cycle.

No parameter or diag would cause this if your operater messed with.

 

Couple things to check if there are no alarms.

Check to see if the spindle turns freely when machine is off.

May have a broken belt if the motor does and spindle does not.

 

The other problem could be the Spindle orientaioton switch.

 

This last consist checking wiring connectin

 

Check the Motif PCB to spindle drive Cable 720.

 

Call you local Haas guy and they are pretty good for over the phone trouble shooting.

[Justin Beebe at Folsom Tool]

Go to www.haascnc.com Then go to customer service, then technical forum, then "Ask The Question Man". They respond in about twenty-four hours for free. If you can't wait that long call them like Bill suggests. Until then blame the new guy.

Tazzer, could you post the solution when you find the problem..........could help someone else sometime.

 

 

 

 

sounds like something loose, does it happen at the same place in the program or is it random????
