Hello,
The turret has a noticeable face runout during indexing (looking at the side of the turret, you can see it wobble as it goes around). Sometimes when it retracts, the coupling teeth clash on the flats and it does not completely index. Of course this puts the tool far off center and forward. The more lopsided the tools are, the more likely this will happen. It is somewhat random and not always the same tool. In the past, I have heard it clunk during a tool change, but it always fully completed the index.
I did have a crash during a tool change recently. Perhaps that crash pushed it over the edge? However, it did not knock the turret out of alignment.
I did clean off the proximity switches. I don't think there is an additional electrical problem. I think it is wear and or damage.
I don't have an exploded view of the turret. I have only ever had it apart far enough to change the alignment pins.
Anything I should know before continuing to diagnose and disassemble it?
I have a few jobs to finish on the lathe first. I am using the optional stop during tool changes to visually make sure the index is completed before continuing.
Thanks,
Bill
