CNC Retrofit for Bridgeport Mill: Restore Precision and Enhance Performance

The Bridgeport Mill is a legendary machine known for its versatility, durability, and reliability. However, as technology advances, many machine owners are considering retrofitting their older Bridgeport Mills with computer numerical control (CNC) systems. In this blog post, we will explore the benefits of CNC retrofitting, the process involved, and how it can transform your Bridgeport Mill into a high-performance machining center.

Why Retrofit your Bridgeport Mill?

1. Enhanced Precision: By retrofitting your Bridgeport Mill with a CNC system, you can achieve unparalleled precision and repeatability in your machining operations. CNC control eliminates human error and allows for microscopic adjustments, resulting in higher accuracy and improved part quality.

2. Increased Productivity: With a CNC retrofit, your Bridgeport Mill can operate continuously without manual intervention. CNC programming enables automated tool changes, multiple operation setups, and complex machining sequences. This leads to significant time savings and increased productivity for your shop.

3. Expanded Capabilities: CNC retrofitting opens up a whole new world of possibilities for your Bridgeport Mill. You can easily perform complex 2D and 3D machining, contouring, pocketing, drilling, and tapping. The ability to execute advanced machining operations enhances your shop's versatility and competitiveness.

The Retrofitting Process

The CNC retrofitting process for your Bridgeport Mill typically involves the following steps:

Step 1: Machine Evaluation

Before starting the retrofit, an experienced technician evaluates your machine to determine its overall condition, mechanical stability, and suitability for retrofitting. This assessment helps identify any potential issues that may need to be addressed.

Step 2: Design and Integration

Based on your specific requirements, the technician designs and integrates a CNC retrofit kit that best suits your Bridgeport Mill. The kit usually includes motors, drive systems, encoders, control panels, and software.

Step 3: Installation and Testing

The retrofit kit is installed by the technician or a team of experts. The process involves removing manual controls, mounting new components, wiring, and configuring the CNC software. Rigorous testing is conducted to ensure all the axes, motors, and sensors are functioning flawlessly.

Step 4: Training and Support

Once the retrofit is complete, training is provided to familiarize your operators with the new CNC system. Ongoing technical support and maintenance services are also offered to ensure optimal performance and troubleshoot any issues that may arise.

Choosing the Right CNC Retrofit Kit

When selecting a CNC retrofit kit for your Bridgeport Mill, consider the following:

  • Compatibility with your Bridgeport Mill model
  • Quality of components and reputation of the manufacturer
  • User-friendly software interface and ease of programming
  • Expansion options for future upgrades
  • Availability of technical support and documentation


CNC retrofitting offers an excellent opportunity to revive your Bridgeport Mill and elevate its performance to meet modern machining demands. With enhanced precision, increased productivity, and expanded capabilities, a retrofit can breathe new life into your trusted machine. Choose a reliable retrofit kit, consult with experts, and enjoy the benefits of a CNC-controlled Bridgeport Mill.
