We Specialize in the Repair
and Refurbishment of NC/CNC,
and Robotics
Galco Industrial Electronics specializes in the repair and refurbishment of NC/CNC & Robotics from hundreds of manufacturers. Since 1975 our technicians have been repairing NC/CNC & Robotics and other industrial electronic equipment including Circuit Boards, Drives/Motors, Power Control Equipment, Test Equipment, and many other Industrial Controls.
CNC machining and robotics requires tight tolerance and precise calibration of all components in the system so that they may work together to output the best product possible. Regular maintenance of these systems is required to keep all components running smoothly. Any single component failure could cause an entire system shutdown.

CNC Machines are Some of
the Most Reliable Pieces of
Equipment in your shop
CNC Machines are very durable, very consistent, and offer the kind of precision you need for your most demanding applications. But the complexity involved in a CNC system can lead to several issues. Even the smallest problems can be frustrating, derailing the exact, pinpoint precision the machines are designed to provide. Improper tools, settings, maintenance and programming can all lead to machining errors. Keep an eye on your material during machining to catch CNC machine errors early. Rough edges or burning are signs of bad tools. Material sliding around during cutting may indicate loose bolts or excess debris in the machine.
Common NC / CNC Faults
Bad or Intermittent Connections

Loose or faulty connections can be unpredictable in CNC systems. Make sure your system is properly connected to a power supply. This includes both motors and drives. Be sure there are no faults between the CNC machine and its controller.

Axis Not Homing or Working

Your CNC system should maintain machine zero and part zero indefinitely if working correctly. Loss of positioning is a sign of mechanical or electrical problems. Typically, this can easily be explained by mechanical slippage. Any of the axes can suffer loose clamping bolts, and your mill can rotate or shift front to back in an undesirable manner.

Servo Drive and Motor Faults

Servo motor failure can be attributed to several factors. If there is no rotation, check for loose connections or foreign matter in the motor. An excessive duty cycle can lead to overheating, or worn bearings. If you are using a DC motor, consider the degree of wear on the brushes.
