NC servo feeders are integral to high-precision machinery, boasting simplicity in operation, high feeding accuracy, low failure rates, and extended service life. Despite their robustness, even the finest machinery requires regular maintenance to sustain peak performance over time. Daily and periodic maintenance routines are vital for ensuring the long-term stability and efficiency of your NC servo feeder. Let’s delve into the essential aspects of maintenance:

I. Daily Maintenance:

Lubrication and Drainage:

  • Lubrication: Keep the gear part of the NC servo feeder roller well-lubricated by applying gear grease. Regularly replenish or replace the gear oil to maintain optimal performance.
  • Drainage: Over time, the NC servo feeder may accumulate water in its three-point combination, disrupting its functionality. Ensure smooth operation by draining excess water through the designated button below the water collection point.


  • Check the functionality of the NC servo feeder’s timer.
  • Remove any debris lodged between the rollers.
  • Inspect for foreign objects within the gears of the NC servo feeder.
  • Verify the normality of oil and gas pressure, ensuring that pressure gauges indicate within acceptable ranges.
  • Detect and address leaks in the pneumatic supply system.
  • Tighten any loose screws and nuts connecting mechanical structures.
  • Ensure proper parallelism between feeding rollers.
  • Examine various parts of the NC servo feeder for damage, deformities, abnormal noises, or operational irregularities.
  • Scrutinize switches and indicator lights on the operation panel for any anomalies.

II. Periodic Maintenance:

External Power Wiring Inspection:

  • Examine the external power wiring for deformations, damages, leaks, or short circuits.

Operation Switches Check:

  • Ensure the functionality of panel buttons, checking for conductivity and oil contamination.
  • Assess if there’s any play in the operation panel buttons.

Punch Press Cam Inspection:

  • Confirm normal rotation and action of the cam.
  • Check for oil contamination and wear on contact parts.

NC Servo Feeder Control Box Inspection:

  • Verify intact wire connections and proper functioning of relays.

Oil Pressure Machine Piping:

  • Inspect the condition of oil pressure machine piping for any abnormalities.

Dust Accumulation Check:

  • Check the NC servo system for dust accumulation, ensuring proper functioning of the cooling fan.
  • Regularly inspect and clean the filter in the cooling fan to prevent overheating and potential damage to the control circuit or motor.

Special Attention:

  • Prioritize safety by turning off power before any work or adjustments.
  • Stop the air compressor and release remaining air before inspecting or repairing pneumatic devices.
  • Seek professional assistance for inspecting and adjusting electromagnetic, pressure devices, starters, etc.

By adhering to these comprehensive maintenance guidelines, you can prolong the lifespan and optimize the performance of your NC servo feeder, ensuring seamless operations in your manufacturing processes.
