CNC machining has revolutionized the manufacturing industry with its precise, automated processes. However, over time, these machined parts may become worn or damaged, losing their aesthetic appeal and functionality. That’s where chrome stripping comes into play as an effective method to restore the beauty of CNC-machined products. In this article, we will explore what chrome stripping is, its importance in the CNC machining process, and how it can be used to produce flawless components.

Understanding Chrome Stripping:

Chrome stripping refers to the removal of a chrome-plated layer from a metal substrate using specific chemical agents. This process is essential for restoring or preparing materials for further processing, such as refinishing or re-coating. While chrome plating enhances the appearance and corrosion resistance of components, it may develop imperfections, impurities, or wear and tear over time. Through chrome stripping, the old chrome layer can be removed, allowing for thorough inspection and potential restoration of the underlying material.

The Importance of Chrome Stripping in CNC Machining:

1. Surface Preparation:
For precise CNC machining, having a clean and defect-free surface is crucial. Before starting any machining operation on a component, it must undergo thorough cleaning and stripping procedures to ensure optimal adhesion between the new coating or finishing layer and the base material. Chrome stripping facilitates this vital surface preparation step by removing unwanted layers, providing an ideal foundation for subsequent treatments.

2. Dimensional Accuracy:
During the chrome plating process, certain tolerances are accounted for, leading to an increased thickness of the final part. Consequently, if the component requires strict adherence to specified dimensions, chrome stripping becomes necessary to eliminate any undesired buildup. By stripping away the chrome layer, the original dimensions can be accurately achieved during subsequent CNC machining operations, ensuring compatibility and consistent product quality.

3. Quality Inspection:
Wear and tear, scratches, or even microscopic cracks can occur over time on chrome-plated surfaces. These imperfections could be detrimental to a part's performance and longevity. Chrome stripping enables thorough inspection of the underlying material for any damage or structural issues before commencing further processing. By identifying and rectifying such flaws early in the CNC machining process, the final product's reliability and lifespan are enhanced.

Chrome Stripping for Flawless CNC Machining:

The following steps outline how the chrome stripping process can be effectively integrated into the production cycle of CNC-machined components:

1. Disassembly:
Before chrome stripping, disassemble the component if possible, as it allows better access to all areas and helps avoid potential damage during the stripping process.

2. Chemical Bath Selection:
Choose an appropriate chemical bath according to the type of chrome plating used. Different types of chromes require specific chemicals for effective stripping without damaging the base material. Consulting with experts or referring to industry guidelines is recommended to ensure safe and accurate results.

3. Immersion and Agitation:
Immerse the components in the selected chemical bath, ensuring complete coverage. Agitate the solution gently to expedite the stripping process and aid in the removal of old chrome layers. The duration of immersion varies depending on the thickness and condition of the chrome layer.

4. Rinse and Neutralize:
Once stripped, rinse the parts thoroughly to remove any residue or remaining chemicals. It is crucial to neutralize the surface using suitable agents to prevent future corrosion and ensure compatibility with subsequent treatments or coatings.

5. Surface Restoration:
After chrome stripping, inspect the stripped metal substrate for any damaged areas or imperfections that may require repair or preparation. Treatments like re-machining, polishing, buffing, or sanding might be necessary to restore the desired surface finish and prepare the component for additional processes.


Chrome stripping plays a vital role in restoring and improving the quality of CNC-machined products. By removing the existing chrome layer, it allows for thorough inspection, dimensionally accurate machining, and precise surface preparation. Effectively incorporating the chrome stripping process into the production cycle of CNC-machined components yields flawless results while ensuring the longevity and durability required in various industries. With its ability to revive worn or damaged parts, chrome stripping proves to be an essential technique in maintaining the integrity and aesthetics of CNC machined materials. CNC Milling CNC Machining
