In the world of CNC machining, chrome stripping plays a crucial role in achieving high-quality results. This process involves the removal of unwanted chrome plating from various surfaces, ensuring smooth and accurate machining operations. From improving adhesion to enhancing durability, chrome stripping is an indispensable step that helps in producing exceptional products. In this article, we will delve into the significance of chrome stripping in CNC machining and explore its various applications.

Understanding Chrome Stripping in CNC Machining:

Chrome stripping refers to the elimination of chromium coatings from metal components before undergoing machining processes. By removing the existing chrome layer, be it electroplated or hot-dipped, manufacturers can optimize surface quality and ensure precise measurements during CNC operations.

The Process of Chrome Stripping:

1. Surface Preparation:
Before initiating the chrome stripping process, proper surface preparation is essential. This includes thorough cleaning and degreasing of the component using industry-approved solvents to remove any contaminants such as oils, dirt, or grease.

2. Chemical Bath:
The next step involves immersing the component in a chemical bath or utilizing specially formulated stripping agents. These substances break down the chrome layer by either dissolving it or creating a reaction that makes it easy to peel off without damaging the underlying material.

3. Mechanical Removal:
In some cases, especially with thicker chrome layers, mechanical methods are employed to strip away the coating. Abrasive techniques like sandblasting or grinding may be used to effectively eliminate the required amount of chrome while maintaining surface integrity.

4. Rinsing and Drying:
Once the chrome has been stripped off, the component must undergo rinsing to remove any residual chemicals or particles. Subsequently, the part is dried thoroughly to prevent corrosion and prepare it for further processing.

Applications of Chrome Stripping in CNC Machining:

1. Preparing Surfaces for Coating:
One prominent application of chrome stripping is when parts need to be coated with alternative materials like polymers or other metal alloys. By removing the existing chrome layer, a clean and receptive surface is obtained, allowing for optimal adhesion of coating substances.

2. Surface Repair and Refurbishment:
In cases where components have been subjected to wear and tear or corrosion, chrome stripping becomes instrumental in restoring their functionality. Once the defective chrome is removed, further repairs can be executed seamlessly, ensuring enhanced product performance and longevity.

3. Dimensional Accuracy:
Chrome plating may introduce slight dimensional changes to components due to thickness variations. Employing chrome stripping before CNC machining helps eliminate these variations, enabling precise measurements and compliance with design specifications.

4. Customization Opportunities:
Chrome stripping allows manufacturers to modify surfaces as per specific requirements. By eliminating old or unwanted chrome layers, intricate designs, patterns, or engravings can be added during subsequent processes, adding aesthetic appeal or improving functionality.

Key Benefits of Chrome Stripping in CNC Machining:

1. Enhanced Adhesion: Removing old chrome layers promotes stronger bonding between substrates and coatings or subsequent layers.

2. Improved Durability: Stripping off compromised chrome surfaces enables proper refurbishment, maximizing component lifespan.

3. Precision Machining: By eliminating dimensional inconsistencies caused by chrome deposits, CNC operations can achieve accurate and reliable results.

4. Increased Customization: The removal of previous chrome plating presents opportunities for unique finishes and personalized designs.


Chrome stripping plays an integral role in CNC machining, offering various benefits such as improved adhesion, durability, precision, and customization possibilities. Understanding the process and its essential applications allows manufacturers to optimize their products' quality and performance. By employing effective chrome stripping techniques, the quest for superior CNC machining outcomes becomes a reality. CNC Milling
