I've been having a problem with my Mori Seiki SH-403 ATC arm cycling. Intermittently it will not complete the ATC cycle, not always on the same tools.
It will begin the cycle, get partway through, then just stop and bounce a bit. This usually happens anywhere from the first tool change in the program, to after 4 hours of production. Manual tool changes (T#M6 method) work fine as well as using the ATC MANUAL OPERATION in the Custom menu. It usually only seems to happen during a production run.
So far we've tested, checked, and found that all the following are good:
-Motor
-Piston Assembly on top with cam follower
-Both sensors
-Contactor in electrical cabinet
-Hydraulic solenoid block that controls tool clamp/unclamp during ATC Cycle
-Cam followers inside the ATC and all associated roller bearings
-Gears all look good inside ATC. No missing teeth or anything.
My techs and I are pretty much all out of ideas on where to look next. The only alarm it throws is EX0159 (ATC ARM H.P. STAYING OFF).
Any ideas? Anything would be appreciated.
