Fanuc CNC Machine Repair
Flip Error Codes Into Cycle Time.
A frozen FANUC—whether it’s a Robodrill, Robocut, or Roboshot—turns capacity into chaos. Midwest CNC Services rushes factory-trained FANUC techs anywhere in the Midwest TODAY, revives your spindle (or wire, or screw), and locks the bill with a flat-rate, written quote before the first hex key turns.
Fanuc Edition
Problems We Crush
Why is my Robodrill spindle howling and snapping carbide drills?
Bearings or balance are gone. We roll in with a mobile grind-&-balance rig, swap bearings when required, and restore OEM run-out before lunch.
Robodrill just threw ‘SV0401 Servo Alarm’—am I down for weeks?
Skip the factory queue. We scope the αi servo pack, reload parameters, and prove axis motion this shift.
Robocut wire keeps breaking and displays ‘PW0002 Power Alarm’—fatal?
We retune the generator, clean the wire path, and recal fluid conductivity so you’re slicing EDM parts again today.
Roboshot injection cycle stuck on clamp—hydraulic fault code 3004—are we toast?
Only if you wait. We reseal the clamp servo valve, flush hydraulics, and reset stroke encoders on-site.
Fanuc iHMI screen goes blank randomly—how serious is that?
HMI board or power-supply capacitance drop. We swap boards from stock, reload menus, and verify full graphics in one visit.
We keep skipping PM—should we panic?
Absolutely. Deferred maintenance is silent downtime. We craft a FANUC-specific PM cadence, lube criticals, and choke failures before they start.
