Addressing Unwanted Noise in Fanuc Servo Systems

Fanuc servo systems are a staple in modern manufacturing and factory settings, known for their reliability and efficiency. However, like all mechanical systems, they are prone to issues, one of the most common being unwanted noise. This blog aims to provide insights into the causes of such noise in Fanuc servo systems and offer practical solutions. Remember, T.I.E. Industrial offers an array of refurbished CNC parts, including those for Fanuc control systems, making us your go-to resource for maintaining and repairing your equipment.

Understanding the Noise Issue

Noise in servo systems can range from a mild humming to a loud grinding sound. It’s more than just an auditory annoyance; it can be a sign of underlying mechanical or electrical issues that may lead to more significant problems if left unaddressed.

Common Causes of Noise in Fanuc CNC Machines

1. Wear and Tear of Mechanical Components:
   Over time, components like bearings and gears can wear out, leading to increased friction and noise. Models like the Fanuc A06B series often exhibit noise due to wear in their mechanical parts.
2. Misalignment:
   Improper installation or alignment of the servo motor can lead to uneven wear and noise. This is particularly true for precision models like the A06B-6096 series.
3. Electrical Issues:
   Problems with the drive or control system, such as imbalanced voltage or current, can also cause noise. The Fanuc A06B-6079 series is an example where electrical issues might manifest as noise.
4. Lubrication Issues:
   Insufficient or old lubricant in the servo system can increase friction and lead to noise. Regular maintenance is crucial to avoid this problem.

Diagnosing the Noise

Before jumping to solutions, it’s essential to accurately diagnose the source of the noise. This involves:

· Visual Inspection: Check for visible signs of wear, damage, or misalignment.

· Listening: Identify the type of noise and its source. Is it a grinding, screeching, or humming sound?

· Testing: Use diagnostic tools to test the electrical components for any anomalies.

Solutions for Noise Reduction in Your Fanuc Servo System

1. Regular Maintenance:
   Regularly servicing your Fanuc servo system can prevent many noise issues. This includes cleaning, lubricating, and checking for wear and tear.
2. Replacement of Worn Parts:
   If a component is beyond repair, replacing it is the best option. T.I.E. Industrial provides high-quality refurbished parts for Fanuc systems, including hard-to-find components.
3. Realignment and Calibration:
   Proper alignment and calibration of the servo motor and its components can reduce noise significantly.
4. Electrical Troubleshooting:
   Addressing electrical issues, such as voltage imbalance or faulty wiring, is crucial for noise reduction and overall system health.

Preventive Measures

To prevent noise issues in Fanuc servo systems:

· Regularly Schedule Maintenance: Regular checks and maintenance can catch potential issues early.

· Use Quality Parts for Repairs: Always opt for high-quality, reliable parts, like those provided by T.I.E. Industrial.

· Train Your Staff: Ensure your staff is trained to recognize and address the early signs of wear and noise issues.
