I have a strange issue here it seems...
I got in a pr of Hardinge Swiss lathes with 18T controls, with a pr of Iemca Boss 325 feeders some time ago.
Just now got the first one running finally, but:
I am getting error #221 "Movement With open Collet" is the title of the alarm in the manual, and on the panel.
But I am also getting a rider to the alarm on the panel of the feeder of "Beating Feed".
(That phrase not mentioned in the manual)
I am only getting this alarm after completion of the first part on a new bar.
So it loads the new bar
Chucks up
Runs Top Cut routine
Opens collet
Repositions the headstock (feed-out)
Closes collet
Runs that part
Opens collet = FAULT
So it has already done a "feed-out" once and ran the next part before this happens.
It happens every time that it AUTO loads.
My Iemca Service guy is clueless - says that is not a normal issue.
I have adjusted the "B" parameter (pusher length) by a 1/2" to make sure that the bar was in the pusher good.
I tightened up the remnant knife goot'n tight.
I am leaving knife [slide] marks in the bar!
And honestly - prior to those changes - I did have the bar fall out of the pusher a cpl times.
Not anymore.
By the wording of the alarm definition, it seems to only be related to the actual loading distance, and so I have added up to 15" to param #5 [Lube Shut Off] dimension to see if that would help, but nadda.
But if the issue is actually the bar sliding up in the pusher a little further, it should have done that on the first feed, not the 2nd...
It's never done it any other time - other than that second feed.
"It's never done it any other time - other than that second feed."
Until just now!
I had just written that sentence and then had to go out and clear the alarm as it was about to end of bar.
And this time it just did it on the second AND the third feed!
Now I s'pose that it is still possible that I don't have the knife set tight enough, but IDK the routine for that. I haven't found that in the manual, but I am only running 3/8" 4140, so compared to a 7/8" bar, I'd think that I have it pretty good? And again - it doesn't doo it on the first feed.
All collets/pushers are all brand new. (Hardinge / Iemca)
Anyone out there experience this before?
