Hello!
We have Kitamura MyCenter 1 with Fanuc 3M control. The machine is old, I belive that it´s around 1983.
The machine has been working fine, but yesterday it stopped.
It´s has been doing very simple program, that only uses y- and x- axis and the spindle is running 5krpm.
The machine stopped in the beginning of the program. When I command in MDI the spindle to run example 5krpm the spindle starts to run, but VERY slowly. I belive that the speed is 3rpm. Also the Z-axis is dead, the X- and Y- axis are working fine. The machine has no alarms, not in the front panel and all the servos have no errors in the cabinet. All ready-lights are green.
In MDI when I command to change tool, the spindle orientates with the right speed, but stops after that (because the Z-axis is not working)
I also tried to start with Cancel + P, but no help.
What is the component that shares spindle and Z-axis? That could be the culprit...
Thanks, is someone has even a clue/suggestion for this problem!
