In the world of CNC machining, chrome stripping is a crucial process that plays a significant role in enhancing the durability and aesthetic appeal of various products. Whether it's metal parts for automotive industries or high-quality components for aerospace applications, the process provides an opportunity to achieve superior surface finish, corrosion resistance, electrical conductivity, and wear resistance. In this article, we will delve into the intricacies of chrome stripping and explore its importance in CNC machining.

Understanding Chrome Stripping:

Chrome stripping, also known as chrome removal or chromic acid stripping, is a vital pre-treatment method used in CNC machining to remove existing chrome plating from metal surfaces. By eliminating old or damaged plating layers, manufacturers can rectify flaws, correct imperfections, and prepare the material for subsequent processes like re-plating or other desired finishes.

The Process of Chrome Stripping:

1. Assessment: The first step involves a thorough inspection of the part or component to be stripped. Deformities, areas with poor adhesion, visible peeling, or blisters indicate the need for chrome stripping.

2. Preparatory Measures: Protective equipment, such as goggles and gloves, must be worn before starting any chemical contacting procedures. Additionally, proper ventilation and containment measures are necessary to ensure safety during the stripping process.

3. Chemical Bath: The next stage entails immersing the metal piece in a carefully formulated solution, typically comprised of chromic acid and sulfuric acid. This mixture effectively breaks down the chrome plating on the surface while minimizing damage to the underlying base metal.

4. Removal and Rinsing: Once the chemical reaction has taken place, the part is removed from the bath and thoroughly rinsed to eliminate any residual chemicals. It is essential to perform adequate rinsing to prevent cross-contamination with future plating solutions.

5. Surface Preparation: After stripping, the surface of the component often requires further mechanical cleaning through processes like sandblasting or polishing. This step helps achieve optimum adhesion for subsequent coatings.

6. Inspection and Quality Control: Finally, the stripped part undergoes an inspection to ensure that all old plating has been effectively removed and the material is ready for subsequent treatments.

Benefits of Chrome Stripping in CNC Machining:

1. Enhanced Durability: By removing damaged or deteriorated chrome plating, the component's lifespan can be dramatically extended. A clean surface ensures better adhesion during re-plating or alternative finishing methods, contributing to increased longevity.

2. Corrosion Resistance: The stripped surface allows for the implementation of advanced anti-corrosive coating technologies, protecting the underlying material from environmental factors such as moisture, chemicals, and extreme temperatures.

3. Superior Surface Finish: Chrome stripping removes imperfections and blemishes, creating a smooth base for subsequent coatings or finishes. This results in superior aesthetic appeal and improved quality of the final product.

4. Customization Options: Chrome stripping opens up opportunities for customization by enabling various plating options. Manufacturers can utilize different materials like nickel, zinc, copper, or gold plating to achieve specific functional requirements or desired appearances.


Chrome stripping holds immense significance in CNC machining when it comes to maintaining product integrity and achieving optimal functionality. Through this process, manufacturers remove existing chrome plating, rectify flaws, and prepare components for future treatments. With enhanced durability, corrosion resistance, surface finish, and customization options, chrome stripping emerges as an invaluable technique for producing top-notch products across various industries. By harnessing its potential, manufacturers can increase the performance, durability, and visual appeal of their CNC machined parts and components. CNC Milling
