Mubea Rotaflex CNC Clamp Repair in Puerto Rico Restoring Smooth Axis Movement

A clamp that will not move can stop an entire aluminum extrusion machining process. On this Mubea Systems Rotaflex 4-axis machining center in Puerto Rico, the issue started with Clamp 3 not moving, then expanded into clamp lag errors and mechanical drag.

Finding the fault at Clamp 3

The first step was to verify the drive settings because the drive had been replaced. The settings checked out, so the wiring was measured next.

That test showed an open wire. The break was located at the connector on the clamp. The damaged section was shortened, reconnected, and secured so Clamp 3 could return to operation.

Solving Clamp 4 lagging errors

After Clamp 3 was repaired, the machine still reported Clamp 4 lagging. The drive settings were checked again and were correct.

The wiring told the real story. The insulation was soft and failing, leaving conductors exposed. The power connection was rewired, and the missing brake was replaced to restore proper control.

Restoring smooth axis movement

A mechanical issue also needed correction. The motor bracket was digging into the pinion rack, so it was shimmed up. Reinforcement plates were made, drilled, and fitted to the clamps. All clamps were reinforced.

The Maxon controller settings were then adjusted for smoother movement. A backup of the NC PLC was completed before test running the machine.

This Mubea Rotaflex CNC clamp repair restored controlled clamp movement and gave the machine a safer baseline for production.
