In the world of CNC machining, chrome stripping is a crucial process that involves removing the chrome plating from various components. This article aims to shed light on the intricacies of chrome stripping, its importance in CNC manufacturing, and explore the methods employed for efficient and safe removal. So, let's dive deeper into understanding this essential step in the production cycle.

Understanding Chrome Stripping and its Significance:

Chrome stripping refers to the process of eliminating chrome plating from metallic or plastic surfaces. While chrome plating serves various purposes such as corrosion resistance, improved surface hardness, aesthetic appeal, etc., there are instances when it needs to be removed. For instance, during refurbishment, rework, or design alterations, chrome stripping becomes imperative to achieve desired results.

The Process of Chrome Stripping in CNC Machining:

There are primarily two widely used methods for chrome stripping in CNC machining – chemical stripping and mechanical stripping. Let's delve into each of these techniques:

1. Chemical Stripping:
Chemical stripping involves utilizing specific chemicals capable of dissolving and removing the chrome layer from the substrate efficiently. The commonly used chemicals include sulfuric acid, hydrochloric acid, sodium hydroxide, or proprietary chrome stripping solutions. Extreme caution must be exercised while handling these substances due to their corrosive nature. Adequate protective measures should be taken by wearing gloves, goggles, and working in well-ventilated spaces.

2. Mechanical Stripping:
Mechanical stripping involves employing physical abrasion techniques to remove the chrome plating effectively. Commonly used methods include sandblasting, grinding, or abrasive blasting. These methods require skilled operators who can delicately balance the act of removing the chrome without damaging the underlying material. Mechanical stripping is suitable for large objects or those with intricate designs where chemical strippers may not reach certain areas.

Precautions and Safety Measures:

Regardless of the method chosen, safety should be the utmost priority during chrome stripping. Here are a few important precautions to consider:

1. Personal Protective Equipment (PPE): Operators involved in chrome stripping must wear appropriate PPE such as gloves, goggles, and respirators to protect themselves from chemical exposure or physical hazards.

2. Ventilation: Adequate ventilation is crucial while working with chemicals or producing dust through mechanical stripping. Proper airflow systems can help minimize the risk of inhalation or explosion.

3. Environmental Considerations: It is vital to dispose of the stripped chrome waste responsibly by following local regulations and guidelines. Many jurisdictions require permits or licenses for handling hazardous substances, ensuring minimal environmental impact.

Benefits of Chrome Stripping in CNC Machining:

Now that we understand the process of chrome stripping, let's explore its benefits in CNC machining:

1. Design Flexibility: By removing the existing chrome plating, components can undergo design alterations more easily. This flexibility allows for modifications without compromising the overall quality or functionality of the final product.

2. Surface Preparation: Chrome stripping plays a critical role in preparing surfaces for subsequent treatments like re-plating, powder coating, painting, or welding. Eliminating the chrome layer ensures better adhesion and enhances the longevity of these coating processes.

3. Restoring Functionality: Components that have undergone extensive wear and tear can regain their functionality through chrome stripping. Removal of worn-out chrome plating enables precise refurbishment, extending the life of the component.


Chrome stripping is an essential process in CNC machining that facilitates design modifications, surface preparation, and functional restoration of components. While it involves careful consideration of techniques and safety measures, the benefits provided outweigh the challenges associated with it. With proper knowledge and implementation, chrome stripping can ensure improved efficiency, cost-effectiveness, and overall superior quality of manufactured parts in the world of CNC machining.
