CNC machining has offered tremendous advancements and innovations within various industries. Precision engineering, accurate dimensional control, and seamless repeatability make it a reliable manufacturing process. Among its many applications, one crucial aspect that stands out is chrome stripping.

Understanding Chrome Stripping and its Importance:

Chrome stripping refers to the process of removing chromium plating from surfaces or components using specialized techniques. While chrome-plated finishes are aesthetically pleasing, there may arise situations where rework, refurbishment, or modification becomes necessary. This could be due to scratches, dents, corrosion, or even the need for color change. Thus, chrome stripping serves as an essential step before undertaking any further modification or repair work on CNC machined parts.

The Process of Chrome Stripping:

To achieve successful chrome stripping, specific steps and processes must be followed diligently:

1. Surface Preparation:
Before any actual stripping begins, proper surface preparation is vital. The component's surface needs to be cleaned thoroughly with proprietary cleaners or solvents to remove any contaminants like dirt and oil. This ensures maximum contact between the stripping agents and the surface.

2. Application of Stripping Agents:
Once the surface is prepared, the appropriate stripping agent is applied. Several methods can be employed, including chemical strip baths, electrolysis, or thermal treatments. Each method has its advantages and compatibility requirements based on the material being stripped.

3. Soak Time and Monitoring:
After application, the part is left to soak for a specified duration to allow the stripping agent to penetrate and weaken the chrome layer effectively. During this time, regular monitoring of the part's condition is essential to prevent overstripping, which could potentially damage the underlying substrate.

4. Rinsing and Cleaning:
Following the soaking period, the part undergoes thorough rinsing to remove residual stripping agents. It is vital to ensure complete removal of the stripping agent, as any remaining chemical residue can adversely affect subsequent processes. Post-rinsing, cleaning with water or specialized cleaners aids in preparing the part for further treatments.

5. Inspection and Surface Finishing:
Once stripped and cleaned, an examination of the part's surface is performed to assess its condition and determine if any additional post-stripping treatments are required. Depending on the desired outcome, surface finishes such as polishing, buffing, or coating may be applied to enhance functionality, appearance, or durability.

Advantages of Chrome Stripping:

1. Enhanced Aesthetic Appeal:
By enabling refurbishment or color change, chrome stripping provides versatility in design choices while ensuring a flawless finish that matches specific requirements.

2. Cost-Effectiveness:
Repurposing existing components instead of manufacturing new ones saves costs significantly. Chrome stripping allows for the reutilization of parts without compromising quality or performance.

3. Environmental Benefits:
Recycling and refurbishing parts reduce waste generation and overall environmental impact associated with discarding old components. It promotes sustainable production practices within the CNC machining industry.

4. Improved Component Performance:
Chrome stripping enables inspection and repair of underlying surfaces, eliminating defects, corrosion, and wear. This not only enhances component longevity but also ensures optimal functionality and operational efficiency.


Chrome stripping plays a crucial role in the world of CNC machining, allowing for efficient refurbishment, modification, or color transformation of components. The process requires careful execution, following appropriate methods and techniques to preserve material integrity while achieving satisfactory results. Embracing chrome stripping contributes to cost-effective solutions, reduced environmental footprint, and improved overall component performance in CNC machining applications.
