Anyone know how to shift home position on a C axis built-in motor lathe main and sub spindle?
2000 Fanuc 18i-TA Control. (Mori MSC-501)
The dirt...
This hex threading job I sought threading info on earlier has forced another situation I'm unfamiliar with. Being as it's hex stock I need to use Phase Synchronous (M34) part transfer to work both ends of the part.
Problems:
1) Both spindles are of the built in type and do not have a normal Servo Amps driving their C axis positions. Resetting a home position by flipping a Parameter 1815 bit is not a thing here. The two Spindle Amps are A06B-6088(M) and A06B-6078(S).
2) When both spindles are homed in their respective C axis modes, the jaws are off by around 9 degrees or so. I'm almost positive it is these home positions the machine uses to synchronize the jaw positions during the transfer.
3) Anyone know how to shift these positions? I've been through the parameter manual including spindle motor settings. Other then C axis homing speed, anything that has to do with orientation has nothing entered as far as I can see. Typical M19 orientation is an option on these machines that I do not have from what I gather. I most definitely have Phase Synchronous transfer.
4) Chucks are not mount rotation shift-able. They are where they need to be to work properly.
I have a call into Mori but am doubtful on how long it'll be before I hear anything, while the job just keeps getting hotter.
Non technical chuck questions related to experience of others running dual spindle lathes.
1) Seeing as I have to change things anyway, I would like to orient the main spindle jaws to allow room for tighter access to the face of the chuck on X axis ER32 Live tools. X axis drill lengths are very limited on this machine. Being able to run the live tool nose into the rotational area of the jaws has already proved beneficial on one job. Just thinking it would be nice if C axis home was the setting to allow that to happen. Curious if others have needed or wanted this too?
2) When I fix the orient of the jaws for pass-off, is it smarter to have the jaws directly opposite each other, or rotated 60 degrees apart allowing the sub to nest in tight to the main chuck for a closer pickup? Just wondering what others think about this need or no need. My experience is limited on part transfer.
Any and all help is much appreciated.
