CNC machining is a revolutionary technology that has transformed various industries, allowing for precise and efficient manufacturing processes. One crucial aspect of CNC machining involves chrome stripping. In this article, we will delve into the intricacies of chrome stripping, its significance in CNC machining, and provide an overview of the process involved in producing high-quality chrome-stripped products.

What is Chrome Stripping?

Chrome stripping, also known as chrome plating removal or chrome electroplating stripping, refers to the process of removing a layer of chrome from an object's surface. This technique enables reworking or refurbishing of parts by eliminating old layers of chrome and ensuring an even, clean surface for further treatments or modifications.

The Significance of Chrome Stripping in CNC Machining:

In the realm of CNC machining, chrome stripping holds immense importance due to several reasons:

1. Surface Preparation: Prior to any additional treatment, such as polishing, grinding, or coating, it is vital to remove existing layers of chrome. These layers may be damaged, worn out, or require modification for specific applications. Chrome stripping ensures a pristine surface for subsequent processing steps.

2. Improved Adhesion: In many instances, a new layer of chrome needs to be applied on top of the stripped surface. By removing the old coat, the adhesion between the base material and the fresh chromium layer significantly improves, resulting in enhanced durability and uniformity.

3. Enhanced Aesthetics: Chrome stripping is often performed to restore the aesthetics of machined components. Over time, the external appearance may deteriorate or become covered with imperfections due to wear and tear. The process helps rejuvenate the appearance of the object, giving it a brand-new look.

The Chrome Stripping Process in CNC Machining:

Now that we understand the significance of chrome stripping, let us take a closer look at the process involved in producing chrome-stripped products through CNC machining:

1. Assessment and Preparation: The first step is to assess the condition of the part or object that requires chrome stripping. This evaluation determines whether the entire plating needs removal or specific areas require attention. Subsequently, adequate safety measures should be taken, including wearing protective gear such as gloves, goggles, and a respiratory mask.

2. Chemical Stripping: Chrome stripping is primarily achieved through chemical processes. A suitable stripping agent, typically containing acids or specialized solvents, is carefully applied onto the surface using a brush or other appropriate tools. It is crucial to ensure even application and coverage for consistent results.

3. Removal and Rinsing: After the prescribed time specified by the stripping agent manufacturer, the old chrome layer will begin to dissolve. The stripped parts must then be thoroughly rinsed with clean water, ensuring all traces of the stripping agent are removed. Careful inspection should be undertaken to confirm complete chrome removal.

4. Surface Refinement: Once the chrome has been successfully stripped, the surface may require additional refinements based on the desired outcome. Grinding, polishing, or sandblasting techniques can be employed to smoothen any rough edges, imperfections, or residues left after stripping, resulting in a pristine finish.


Chrome stripping plays an essential role in CNC machining as it allows for surface preparation, improved adhesion, and enhanced aesthetics for machined components. Understanding the process involved in producing chrome-stripped products through CNC machining provides insights into the meticulous approach required to attain high-quality finishes. By employing these techniques, manufacturers can offer durable and visually appealing products across various industries. CNC Milling
