Z axis torque alarm
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.
Re: Z axis torque alarm
Don't know about your Fanucs, but I've seen it happen several times on our Brother HS-70A's.
You have to be very careful greasing the Z-axis.
Over vigorous application will pop the seals, and then your in trouble.
After replacing two Z-axis units on ours we rarely grease the "Z" any more.
