CNC machining has revolutionized the manufacturing industry, enabling precise and efficient production across various sectors. One critical process involved in this technology is chrome stripping. In this article, we will delve into the significance of chrome stripping within the realm of CNC machining and explore its benefits, applications, and methods.

Understanding Chrome Stripping:

Chrome stripping, also known as chromium removal or plating stripping, refers to the process of removing a layer of chromium from an object's surface. This procedure plays a vital role in CNC machining by preparing metal components for further processing, such as adding new coatings or performing additional finishing operations. By eliminating the existing chromium layer, manufacturers can ensure a clean starting point for subsequent processes.

Applications of Chrome Stripping in CNC Machining:

1. Surface Preparation:
Before applying any coatings or finishes onto machined parts, it is essential to strip off the underlying chrome layer completely. Chrome stripping restores the base material's integrity and eliminates potential adhesion issues between different layers, ensuring optimal bonding strength for subsequent treatments like powder coating, electroplating, or painting.

2. Restoration:
In certain cases, old or damaged chrome-plated parts may require rejuvenation. If restoration is necessary due to wear, corrosion, or peeling, chrome stripping allows engineers to start afresh without compromising the structural integrity of the component. Following the stripping process, the part can be re-chromed or treated with alternative coatings to restore its original appearance and performance.

Methods of Chrome Stripping in CNC Machining:

1. Chemical Stripping:
Chemical stripping is one of the most commonly employed methods for chrome removal. It involves submerging the chrome-plated object in a chemical solution specifically designed to dissolve and remove the layer of chromium. The part remains immersed until the desired stripping result is achieved. Depending on the complexity and size of the component, different chemical stripping processes may be utilized. However, careful consideration must be given to environmental and safety factors associated with the chosen stripping agents.

2. Mechanical Stripping:
Mechanical stripping involves physically removing the chrome layer through abrasive methods, such as bead blasting or sanding. This method is generally preferred for larger parts or when limitations exist in using chemical stripping due to safety concerns. Mechanical stripping requires specialized equipment and trained professionals to ensure an even removal of the chrome layer without damaging the underlying material.

Benefits of Chrome Stripping in CNC Machining:

1. Enhanced Adhesion:
By eliminating the existing chromium layer, chrome stripping ensures improved adhesion strength between subsequent coatings or finishes applied to the metal part's surface. This results in longer-lasting performance and reduced chances of delamination or peeling.

2. Versatility:
Chrome stripping allows manufacturers to modify and rework components, accommodating changes demanded by specific applications or design requirements. By providing a clean surface, this process opens avenues for applying alternative coatings or finishes that may enhance the mechanical properties or appearance of the part.

3. Cost-Efficiency:
Rather than discarding worn or damaged chrome-plated components entirely, chrome stripping enables their restoration at significantly lower costs compared to manufacturing new parts. Additionally, it reduces wastage and contributes to sustainable manufacturing practices.


CNC machining has harnessed the power of chrome stripping as a crucial tool for precision manufacturing. The ability to remove the chrome layer successfully prepares surfaces for further treatments while promoting superior adhesion and versatility. Embracing chrome stripping in CNC machining not only optimizes the overall quality of finished products but also supports cost-effective and sustainable strategies within the manufacturing industry.
