On some of our FANUC wire EDM machines, the Z axis stops when
I move it . The torque alarm comes on.
This doesn`t happen all the time.
A few people have told me that if the Z axis is over-greased this will happen,
and if the wrong grease is used it may also happen.
And if the grease is old and dried out it will happen.
Is this a common problem due to poor maintenance, or something else ?
Also There is no obstruction to the Z axis.
Thanks, Tom
