CNC machining has revolutionized the manufacturing industry by providing precise, efficient, and cost-effective solutions for producing various products. One crucial process within CNC machining is chrome stripping, which involves the removal of chromium plating from a metal surface. In this article, we will delve into the details of chrome stripping in CNC machining, its significance, methods involved, and its applications.

What is Chrome Stripping?

Chrome stripping refers to the removal of chromium plating or chrome layer from a component's surface. Chromium plating offers corrosion resistance, durability, and aesthetic appeal to metals, making it widely used in many industries like automotive, aerospace, and electronics. However, components often require modifications or repairs that necessitate chrome stripping before further treatment or processing.

Methods of Chrome Stripping in CNC Machining:

1. Chemical Stripping:
Chemical stripping is one of the most common methods employed in CNC machining to remove chrome layers. It involves immersing the component in a stripping solution that dissolves the chromium plating chemically. The solution breaks down the bonding between the chrome and the material, facilitating its easy removal. Although effective, chemical stripping requires careful handling of the stripping agents due to their corrosive nature.

2. Electrolytic Stripping:
Electrolytic stripping is another method frequently utilized to remove chrome layers during CNC machining processes. This technique utilizes an electrical current to detach the chromium plating from the substrate. The component acts as a cathode or anode while being submerged in a conductive electrolyte bath. By passing electricity through the bath, an electrochemical reaction occurs, creating conditions for the separation of the chrome layer from the base metal.

Applications of Chrome Stripping:

1. Restoring Parts:
Components with damaged or worn-out chrome plating often undergo chrome stripping to restore them to their original glory. Whether it's automotive trim, retro motorcycles, or antique fittings, chrome stripping helps bring back the shine and luster to these parts. Once stripped, the components can be recoated with fresh plating for enhanced performance and aesthetics.

2. Precision Machining:
CNC machining often involves multiple processes like milling, drilling, and grinding. Chrome stripping becomes essential when the presence of chrome layers interferes with accurate measurements or when a particular surface requires modifications that are challenging to achieve through conventional machining techniques. By removing the chrome layer, precision machining becomes easier, allowing for precise tolerances and superior finish quality.

3. Surface Preparation for Further Treatments:
Chrome stripping is also crucial in surface preparation for subsequent treatments such as powder coating, anodizing, or chemical etching. These processes require a bare metal surface to form strong bonds between the coating or treatment material and the component. Thoroughly and accurately stripping the chrome layer ensures optimal adhesion and enhances the durability and appearance of the final product.


In summary, chrome stripping plays an integral role in CNC machining by facilitating repairs, precision machining, and effective surface preparation. With methods like chemical and electrolytic stripping, manufacturers can remove chromium plating from components efficiently. Chrome stripping enables the revival of damaged parts, allows for precise machining, and prepares surfaces for further treatments. Ultimately, understanding chrome stripping in CNC machining empowers manufacturers to optimize their production processes while achieving desired outcomes. CNC Milling CNC Machining
