Repair of XYZ 1060 VMC

Posted on 5th April 2021

XYZ 1060 VMC with a bit of an unusual fault. It initially started out with a Z axis brake fault, when the emergency stop was engaged the head fell under gravity and hit the dead stop.

The motor was diagnosed as faulty and overhauled by a third party and refitted by our customer. Unfortunately now when referencing the machine, the Z axis would climb to It’s extreme limit, max out on current then fall out of control down to the dead stops, It was at this point our customer decided to give us a call as the machine was now deemed to be in an unsafe condition and unusable.

Damaged Z axis

On inspection we found the Z axis reference and hard overtravel switches to be damaged from the previous head crash on dead stops, these were replaced and realigned. We also found the counter balance cylinder to be inefficient as the seals were badly worn, this was rebuilt with new seals and refitted and tested by us.

On further inspection the Z axis brake relay was found to have a loose connection which we believe was most likely the root cause of the original fault which then cascaded into multiple failures due to cause effect syndrome. Our customer’s exact words “I wish I’d called you in the first place!”
