CNC machining has revolutionized various industries by providing precision and accuracy in manufacturing processes. One essential aspect of CNC machining is chrome stripping, a crucial step involved in the production of high-quality products. In this article, we will explore the process of chrome stripping, its significance in CNC machining, and how it contributes to product development.

What is Chrome Stripping?

Chrome stripping refers to the removal of a chromium coating from a metal surface. This process involves stripping the plated layers down to the base material using chemical or mechanical methods. Although commonly associated with automotive parts, chrome stripping plays a vital role in many other industries where durability, aesthetics, and functionality are key factors in product performance.

Importance of Chrome Stripping in CNC Machining:

1. Surface Preparation:
Before implementing any further manufacturing operations, ensuring an adequately prepared surface is essential. Chrome stripping allows for proper adhesion of subsequent coatings such as plating, powder coating, painting, or any form of surface treatment. It eliminates unwanted materials, irregularities, and corrosion from the surface, thereby creating an ideal start point for the next steps in CNC machining.

2. Material Compatibility:
Certain applications require customizations that demand different base metals instead of the default option available. By removing the existing chrome layer through stripping, manufacturers can customize their product attributes according to specific requirements. This flexibility enables them to optimize the properties of the final product, improving strength, durability, or even altering electrical conductivity if needed.

3. Refurbishment and Repair:
In situations where used or damaged parts need repair or refurbishment, chrome stripping becomes a valuable technique. It allows the extraction of degraded or faulty chromium layers, making way for subsequent treatments that restore the part's functionality and aesthetic appeal. Furthermore, chrome stripping helps save resources by allowing the reutilization of components, reducing waste, and cost implications associated with replacing the entire part.

The Chrome Stripping Process in CNC Machining:

1. Surface Evaluation:
An initial step in the chrome stripping process involves inspecting the metal surface for possible defects, wear, or irregularities. Analyzing the thickness of the existing coating is crucial to determine the type and duration of treatment needed before proceeding further. This evaluation ensures that accurate steps are taken during the subsequent processes, guaranteeing an optimal outcome.

2. Chemical or Mechanical Stripping:
Chrome stripping can be achieved through two primary methods: chemical and mechanical. Chemical stripping employs various solutions specifically formulated to remove chrome without causing damage to the base metal. On the other hand, mechanical stripping utilizes abrasive techniques such as grinding, blasting, or sanding, making it useful when dealing with more robust coatings or intricate surfaces.

3. Masking and Protection:
Certain parts may have specific areas where the chrome coating should remain intact, requiring appropriate masking materials like tapes or specialized coatings. These protective measures safeguard critical features from unwanted stripping, ensuring their functionality and aesthetic appeal are preserved. Accurate masking eliminates potential rework and maintains overall productivity during the chrome stripping process.

4. Post-Stripping Treatment:
After removing the chrome layer, the stripped surface might require additional treatments to ensure proper adhesion, resistance to corrosion, or enhanced appearance. Depending on the final application, manufacturers can choose from an array of surface finishes, including plating, powder coating, painting, or even leaving it bare with a polished finish. These post-treatment options contribute significantly to the final product's quality and customer satisfaction.


CNC machining, coupled with the intricate process of chrome stripping, enables the production of high-quality products while maintaining precise specifications and functional attributes. The removal of chrome layers plays a vital role in achieving superior results in terms of durability, aesthetics, material compatibility, refurbishment, and repair. By understanding and implementing the efficient and necessary steps involved in chrome stripping, manufacturers can optimize their manufacturing processes and deliver exceptional products to meet the ever-evolving market demands.
