CNC (Computer Numerical Control) machining has revolutionized the manufacturing industry by offering unparalleled precision and efficiency. In this article, we will explore the intricate process of chrome stripping using CNC machining techniques. From its significance to the step-by-step production procedure, let us embark on a journey into the world of chrome stripping.

Understanding Chrome Stripping:

Chrome stripping refers to the removal of chrome plating from an object's surface for various reasons, including restoration, repair, or preparation for re-plating. The goal is to eliminate the existing chromium layer without damaging the underlying material. This technique finds applications in the automotive, aerospace, and electroplating industries where chrome-coated parts need servicing or refinishing.

The Role of CNC Machining in Chrome Stripping:

CNC machining plays a crucial role in the precise execution of chrome stripping processes. The automated nature of CNC machines ensures consistent results, reducing human error and enhancing overall accuracy. By programming the machines with specific instructions, every aspect of chrome stripping can be meticulously controlled, from tool movement to material removal rates.

The Chrome Stripping Process:

1. Surface Preparation:
Before initiating the chrome stripping process, it is essential to prepare the surface by thoroughly cleaning and degreasing it. Any contaminant left behind could interfere with the subsequent steps.

2. Protective Measures:
Once the surface is ready, it must be protected from any unintended damage during the chrome stripping process. Applying masking agents or tape to areas that should not undergo treatment is crucial. Additionally, protective coatings may be added to safeguard sensitive components surrounding the chrome-coated area.

3. Precision Tooling:
Based on the complexity and dimensions of the part being stripped, appropriate tooling needs to be selected and programmed into the CNC machine. High-precision tools, such as end mills or grinding wheels, are utilized to gradually remove the chrome layer.

4. CNC Programming:
Before executing the stripping process, a CAD (Computer-Aided Design) file needs to be converted into machine-readable code using CAM (Computer-Aided Manufacturing) software. This code guides the CNC machine's movements and specifies the toolpaths required for efficient removal of chromium without causing damage.

5. Machining Execution:
With all preparations in place, the CNC machine commences the exacting chrome-stripping operation. The programmed instructions guide the machine as it carefully removes the desired amount of chrome with each pass. Throughout the process, operators monitor critical parameters such as cutting speeds, feed rates, and coolant application to ensure optimal results.

6. Post-Stripping Finishing:
Once the chrome plating is successfully stripped, meticulous post-processing steps follow. Precise cleaning techniques are employed to eliminate any remaining chemicals or debris from the surface. Special attention is given to avoid scratching or damaging the base material during this stage.

7. Additional Processing Options:
Depending on the intended use of the stripped part, further processing options may include polishing, buffing, or surface treatment to restore its appearance or improve its functionality. The versatility of CNC machining allows for seamless integration of these additional steps.


By leveraging the accuracy and automation provided by CNC machining technology, chrome stripping has become an incredibly precise and efficient process. Through careful programming and execution, chromed parts can be seamlessly refurbished or repaired, ensuring their optimal performance. From automotive enthusiasts eager to restore vintage cars to aerospace professionals seeking to maintain precision components, CNC-machined chrome stripping offers a reliable solution for removing chrome coatings while preserving the integrity of underlying materials.
