Okuma tailstock issue

[T_MALENA]

All you Okuma guru's... I have a couple LB4000's with w-axis tailstocks. I can get the t/s to advance & retract, jog, handwheel etc. But I'm wanting to get the t/s to advance in at a specific time & stop at a location(with no pressure on the part), run the program & then retract back at end of program. I should refer to this as the t/s w-axis because I removed the t/s & replaced it with a alum mounting block & air driven tooling.

 

I keep getting alarms. My Okuma rep is telling me it needs to see pressure on the t/s in order to run. I'm not buying it. Any ideas?

 

Thanks, Tim

M120 No work confirmation?

M156 Center work interlock OFF?

M167 Ignoring tailstock advance/retract interlock ON?

M432 Tailstock error detect OFF?

Thanks Chris. I'll try it.

If none of those work, and nobody else has good info, email me and we'll see if we can get the straight dope

It thickens. The parameters were "adjusted" on one of the machines. I'll have to table this for a little, need to let production run their machines for the rest of the day. Someone has the tailstock barrier & turret barrier over tweeked. As soon as I try to jog the t/s it alarms. Disabled it'll move.

It would be so much easier if these machines were locked. At least I'd have a reason to be yelling at myself - although arguing/yelling at myself does keep people away.

What does this do? Let's change it and find out...

I may be a bit late and you may have figured this out by now. I was able to trick the machine by setting different home positions for the tailstock. when i wanted the tailstock advanced without pressure, i would set that position as home. then in your program, tell the tailstock to go home. I don't work on Okuma's anymore so the code is not fresh in my mind. I could look it up if needed though.

hope this helps.
