CNC machining is a manufacturing process that utilizes computer-controlled machines to produce complex and precise parts. This technology has revolutionized various industries, from automotive to aerospace. However, over time, the finishing on these machined parts may deteriorate or become damaged. In such cases, chrome stripping comes into play as an effective restoration technique. This article dives deep into the significance of chrome stripping in CNC machining processes and outlines its production method.

Understanding Chrome Stripping:

Chrome stripping refers to the removal of plated or coated finishes from metal surfaces. It involves eliminating layers of chrome or other materials applied during the plating process. Although chrome plating enhances the aesthetic appeal and corrosion resistance of components, damage or wear can occur due to impacts, abrasions, or aging. Consequently, the need for chrome stripping arises for functional or restorative purposes.

The Production Process of Chrome Stripping:

To understand the production process involved in chrome stripping for CNC machined parts, let's break it down into steps:

1. Evaluation:
Before initiating the stripping process, thorough evaluation of the component is essential. Inspection helps determine the level of chrome adhesion, extent of surface damage, and overall condition of the part. This analysis ensures proper treatment planning and facilitates efficient outcomes.

2. Surface Preparation:
Preparing the surface prior to chrome stripping is crucial for achieving optimal results. The part is thoroughly cleaned using specialized chemical solutions to remove grease, dirt, and contaminants. Surface preparation sets the foundation for successful chrome stripping.

3. Chemical Stripping:
Chemical baths are used in the next step to strip the existing chrome layer. Multiple factors, including the type of chrome coating and base material, determine the appropriate solution composition and immersion time. An experienced technician monitors this stage carefully to prevent any harm to the substrate.

4. Neutralization and Rinsing:
Once the chrome layer is successfully removed, the part undergoes a neutralization process to eliminate any remaining chemical residues. Thorough rinsing with deionized water ensures complete removal of stripping agents and prevents re-deposition during subsequent plating processes.

5. Surface Reconditioning:
After chrome stripping, restoring the original surface condition becomes necessary. The component may require polishing or additional treatments to address imperfections caused by the stripping process. This step focuses on achieving the desired finish before proceeding with further coatings or plating.

Significance of Chrome Stripping in CNC Machining:

1. Restoration and Refurbishment:
CNC machined parts often face wear and tear over time. By employing chrome stripping techniques, manufacturers can restore components to their former glory, ensuring both functionality and aesthetic appeal. Properly refurbished parts provide extended lifespan and maintain high-quality performance.

2. Improved Recycling Efforts:
Chrome stripping allows for efficient recycling and reuse of metal substrates. Through various environmentally friendly practices, stripped components can be reintroduced into manufacturing cycles, reducing waste and conserving valuable resources.

3. Flexibility in Design Changes:
In certain cases, design modifications necessitate changes in surface finishes. Instead of creating entirely new parts, which incurs additional expenses, chrome stripping enables the alteration of existing components. This flexibility enhances cost-efficiency without compromising product integrity.


Chrome stripping serves as an essential technique within the realm of CNC machining, facilitating the restoration and refurbishment of machined parts. Understanding the intricacies involved in the production process helps manufacturers appreciate its significance in extending the life cycle of components. By engaging in effective chrome stripping practices, companies contribute to sustainable manufacturing approaches while simultaneously delivering products that meet customer expectations. CNC Milling
