Chrome stripping is an integral process in the production of high-quality, precision-engineered products. When it comes to CNC machining, chrome stripping plays a crucial role in achieving desired finishes and functionalities. In this article, we will explore the significance of chrome stripping in CNC machining and delve into the various aspects of this essential manufacturing process.

What is Chrome Stripping?

Chrome stripping, also known as chrome removal or reverse electroplating, involves removing layers of chromium from a metal surface. The purpose of chrome stripping varies depending on the desired end result. It is commonly used to repair damaged parts, prepare surfaces for re-chroming, restore components to their original state, or enable further machining processes.

CNC Machining and Chrome Stripping:

CNC (Computer Numerical Control) machining is a highly sophisticated manufacturing technique that utilizes automated tools guided by pre-programmed computer software. It offers unparalleled precision, versatility, and efficiency in creating complex parts and components. With the integration of chrome stripping within the CNC machining process, manufacturers can achieve superior finishes, corrosion resistance, and improved material properties.

Key Applications of Chrome Stripped Components:

1. Surface Preparation: Chrome stripping allows for complete removal of existing chrome plating before applying other coatings or treatments. This ensures proper adhesion between different layers, reducing the risk of delamination or peeling.

2. Repair and Restoration: Damaged or worn-out parts often require refurbishment before they can be reused. Chrome stripping enables the elimination of damaged regions, effectively preparing the component for further repairs or restoration work, such as welding or reshaping.

3. Precision Enhancements: By selectively removing chrome plating from specific areas, CNC machinists can create intricate patterns or cavities that enhance functional features. This opens up possibilities for customized designs tailored to specific applications.

4. Specialized Coating Applications: Chrome stripping allows for controlled surface preparation, enabling the application of specialized coatings like thermal spray or ceramic finishes. These coatings enhance wear resistance, improve thermal management, or provide specific electrical properties.

Chrome Stripping Process in CNC Machining:

The chrome stripping process occurs before or after conventional CNC machining operations, depending on the desired outcome and precision requirements. The general steps involved are as follows:

1. Cleaning and Surface Preparation: The component is thoroughly cleaned to remove any contaminants, oils, or debris that may interfere with the stripping process.

2. Immersion Bath: The part is immersed in a chemical solution specifically designed for removing chromium plating. Electrolysis is then employed, causing the chrome ions to be reduced and separated from the substrate, facilitating easy removal.

3. Rinsing and Drying: Once stripped, the component is rinsed in water to remove any residue left by the stripping chemicals, followed by air drying or forced drying using appropriate methods.

4. Post-Stripping Treatments: Depending on the intended purpose of the component, post-stripping treatments such as passivation, polishing, or coating applications can be performed to ensure its final functional and aesthetic qualities.

Benefits of Integrating Chrome Stripping in CNC Machining:

1. Enhanced Precision: Chrome stripping enables CNC machines to achieve finer tolerances and intricate designs, resulting in precise and accurate components.

2. Improved Durability: By optimizing the surface finish through chrome stripping, components gain better corrosion resistance, wear resistance, and overall longevity.

3. Cost Efficiency: Reusing stripped components reduces waste while retaining their original structural integrity. This provides cost savings compared to producing entirely new parts.


In the world of advanced manufacturing processes, chrome stripping holds a significant place alongside CNC machining. The combination ensures superior quality, performance, and customization opportunities for engineered products. Understanding the importance of this symbiotic relationship empowers manufacturers to create exceptional end products by harnessing the capabilities of CNC machining and incorporating chrome stripping techniques.

Remember, whether it's for surface preparation, repair and restoration, precision enhancements, or specialized coating applications, chrome stripping is an essential step to unlock the full potential of CNC machining. CNC Milling
