CNC Retrofit for Bridgeport Mill

In this blog post, we will explore the process of retrofitting a Bridgeport mill with a CNC (Computer Numerical Control) system. A CNC retrofit can enhance the capabilities of a manual mill, allowing for precise and automated machining operations. With the rise of computer-aided designs and the need for increased productivity, a CNC retrofit is a cost-effective solution for improving the performance of your mill.

Why Retrofit?

Manual milling machines, like the Bridgeport mill, have been reliable workhorses for decades. However, they are limited in functionality and require extensive manual labor. By retrofitting your Bridgeport mill with a CNC system, you can enjoy numerous benefits such as:

  • Increased productivity: CNC machines can perform complex operations quickly and accurately, reducing production times significantly.
  • Enhanced precision: With CNC controls, you can achieve micron-level accuracy, ensuring parts are machined to exact specifications.
  • Improved repeatability: CNC systems allow you to save programs and replicate them consistently, reducing errors and improving overall efficiency.
  • Expanded capabilities: A CNC retrofit opens up a world of possibilities, enabling 3D machining, engraving, and more.

Choosing the Right Retrofit Kit

When retrofitting your Bridgeport mill, selecting the appropriate CNC kit is crucial. Factors to consider include:

  • Compatibility: Ensure the retrofit kit is compatible with your specific Bridgeport mill model.
  • Features: Evaluate the features offered by the kit, such as spindle control, tool changers, and coolant systems, to determine the best fit for your needs.
  • Ease of installation: Look for kits that come with clear instructions and tutorials to simplify the retrofitting process.
  • Reliability: Research customer reviews and testimonials to ensure the kit you choose is reliable and from a trusted manufacturer.

The Retrofitting Process

Retrofitting a Bridgeport mill generally involves the following steps:

  1. Machine preparation: Clean the mill thoroughly and ensure it is in good working condition.
  2. Stripping down: Remove unnecessary components and accessories, leaving only the essential parts.
  3. Installation of CNC kit: Follow the manufacturer's instructions to install the CNC retrofit kit, including mounting the control panel and connecting the motors.
  4. Wiring and connections: Connect the spindle motor, limit switches, and any additional accessories, ensuring proper electrical connections.
  5. Testing and calibration: Power on the system and perform various tests to ensure all components are functioning correctly. Calibrate the CNC system for accurate positioning.

Maximizing the CNC Retrofit

Once your Bridgeport mill is retrofitted with a CNC system, there are several ways to optimize its performance:

  • Training: Invest in operator training to fully leverage the capabilities of your CNC mill.
  • Tooling and fixtures: Use high-quality tools and fixtures specifically designed for CNC machining.
  • Maintenance: Regularly clean and lubricate your mill to ensure smooth operation and longevity.
  • Software upgrades: Stay up-to-date with the latest CNC software versions and take advantage of new features.


A CNC retrofit for your Bridgeport mill can transform it into a powerful and versatile machining tool. With improved precision, increased productivity, and expanded capabilities, the retrofit is a worthwhile investment. By carefully selecting the right kit, following proper installation procedures, and optimizing the CNC system's performance, you can unlock the full potential of your mill and take your machining projects to new heights.
