Troubleshooting Aging CNC Machines with Refurbished Fanuc Parts

By: Heather Johnson - May 12, 2026

CNC Machines do not age like fine wine. This complex equipment requires regular care to maintain exceptional performance. Older CNC machines can be challenging, but with the right strategies and access to parts, these machines can continue to perform efficiently and are not ready to be retired. 

Many manufacturing facilities still rely on aging CNC machines, and addressing their maintenance needs is crucial for sustained productivity. Let’s explore common issues faced with older CNC machines and provide solutions, mainly focusing on refurbished Fanuc parts.

Common Issues with Older CNC Machines

Older CNC machines, while robust, can face several challenges as they age. Here are some common issues:

  • Wear and Tear
    • Over time, the mechanical components of CNC machines, such as servo motors, power supplies, and controllers, can wear out, leading to decreased performance and potential breakdown.  
  • Outdated Control Systems
    • Older CNC machines may struggle to keep up with newer models as technology advances. This can result in inefficiencies and compatibility issues with modern software and tools.
  • Component Failures
    • Critical components such as motors, drives, and controllers can fail, causing significant downtime.
  • Difficulty in Finding Replacement Parts
    • As manufacturers phase out older models, finding genuine replacement parts becomes increasingly difficult. Many original manufacturers may no longer produce or support these parts, making it necessary to find reputable third-party suppliers.

The Importance of Regular CNC Maintenance

The need for regular maintenance cannot be emphasized enough, as it is essential to keep older CNC machines running smoothly. Here are some maintenance tips:

  • Schedule inspections to identify potential issues before they become major problems.
  • Ensure that all moving parts are adequately lubricated to reduce wear and tear.
  • Regularly calibrate the machine to ensure accuracy and precision in operations.
  • Clean the machine, especially regarding metal shavings and dust, to prevent blockages and wear.
  • Upgrade specific components to improve performance and sustain operations.  

Some additional tips for extending the life of your CNC machines include:

  1. Keep a Maintenance Log

Keeping a detailed maintenance log can help you track the condition of your CNC machines and schedule timely inspections and part replacements. This proactive approach can prevent unexpected breakdowns and extend the life of your equipment.

  1. Train Your Staff

Properly trained staff can identify potential issues and perform routine maintenance tasks effectively. Investing in training for your team can ensure they have the knowledge and skills to keep your CNC machines in optimal condition.

  1. Use High-Quality Parts

Using high-quality parts, such as refurbished Fanuc components, can significantly improve the reliability and performance of your CNC machines. Partnering with T.I.E. Industrial, a leading supplier, ensures you have access to the best parts for your equipment.
