In the realm of CNC (Computer Numerical Control) machining, precision and efficiency are paramount. To achieve these qualities, manufacturers often employ a technique called chrome stripping. This process enables the removal of a chrome surface from an existing component or the application of a fresh chrome coating to enhance the durability and performance of machine parts. In this article, we will delve into the intricacies of chrome stripping, its significance, and how it contributes to the production process.

Understanding Chrome Stripping:

Chrome stripping refers to the chemical removal of chrome plating from metal surfaces. It is commonly used in CNC machining to improve accuracy and ensure proper functionality of components. The procedure involves submerging the part in a specialized solution that effectively dissolves the chrome layer while minimizing damage to the base material. By removing the older and possibly damaged chrome layer, the targeted part gains renewed longevity, smoothness, and can even be recoated to restore optimal performance.

The Importance of Chrome Stripping in CNC Machining:

1. Enhanced Component Precision:
During the manufacturing or restoration of machine parts, precise tolerance levels must be maintained for seamless operation. However, over time, chrome plating on vital components may wear off or become imperfect, compromising their performance. Through chrome stripping, flaws caused by abrasion, corrosion, or irregularities are eliminated. Consequently, the stripped part can undergo re-coating or further refining, ensuring accurate dimensions and a long-lasting finish.

2. Surface Preparation:
Chrome stripping plays a crucial role in surface preparation before recoating the parts. After removing the old chrome from the workpiece, additional processes such as polishing, deburring, or even stress relief treatments can be performed if necessary. These augmentations result in a smoother, defect-free surface ready for the subsequent application of new chrome or different coatings like nickel or zinc.

3. Environmental Benefits:
While the procedure involves using chemicals for stripping, it is an environmentally friendly alternative compared to traditional mechanical removal methods. Chrome stripping allows manufacturers to maintain their sustainability goals by reducing waste generation and minimizing energy consumption during surface refinishing or restoration processes.

The Chrome Stripping Process:

Chrome stripping follows several essential steps to ensure effective removal of chrome plating from metallic surfaces:

1. Surface Preparation:
Before commencing the stripping process, thorough cleaning of the part's exterior is vital. This removes any dirt, grease, or debris that could hinder the effectiveness of the stripping solution.

2. Immersion in Strip Solution:
The prepared component is then immersed in a specialized strip solution designed to dissolve chrome plating while minimizing damage to the underlying metal. The concentration and duration of immersion are crucial factors determined by experts based on the specific requirements of the part being stripped.

3. Neutralization and Cleaning:
After removing the workpiece from the strip solution, it must undergo a thorough rinsing process to remove all traces of the chemical stripper. An acid neutralizer is often used to stabilize the pH level before final cleansing.

4. Final Inspection & Post-Stripping Processes:
Once cleaned and dried, the part should be inspected to assess its condition and determine further treatment if needed. Polishing, polishing compound application, coating with protective substances, or even recoating can be performed at this stage, depending on the intended use and desired outcome.


Chrome stripping plays a critical role in CNC machining, allowing manufacturers to restore and enhance precision, functionality, and durability of machine components. By effectively removing old or faulty chrome layers, maintaining strict tolerances, and providing a clean surface for additional treatments, this technique contributes significantly to the manufacturing sector. As CNC machining continues to advance, incorporating chrome stripping ensures superior performance, prolongs the lifespan of parts, and ultimately benefits industries leveraging the power of modern automation technology.
