Hello all,
I'm new here and this is my first post. I have an MV-55 with Fanuc 11M controls. I have been having intermittent problems with the tool changer lately. One problem has been the tool does not unlock from the spindle at times. The arm clamps to the tool holder and then as it moves down to remove it from the spindle, the arm will slip off and continue the tool change. As it rotates to bring around the next tool, the spindle tool is still in the spindle. Of course it ends with a crash of the new tool hitting the tool in the spindle.
The current problem is it will not complete a tool change.
All is fine until the tool is placed into the spindle. At this point everything comes to a stop. After a few seconds the alarm will come up. At that point I do M31, M35, to clear it up. This happens on every tool change. Sorry for such a long post. Any help would be appreciated.
