Galco retrofits obsolete CNCs
On machine tool mills, grinders, lathes and routers with FANUC FA America products. A complete retrofit upgrades both servo motors and drives, providing the best possible return in precision, speed, and efficiency.
Verification and Troubleshooting Tools
During identification, replacement planning, and commissioning, basic verification tools can help confirm electrical conditions and reduce rework. You may need a multimeter for standard electrical checks or an oscilloscope for signal troubleshooting when waveform behavior needs to be verified.
