CNC machining is a versatile and precise manufacturing process that involves the use of computer-controlled machines to produce various parts and components. One important aspect of CNC machining is surface finishing, which includes techniques like chrome stripping. In this article, we will explore what chrome stripping is and how it is used in the world of CNC machining.

What is Chrome Stripping?

Chrome stripping refers to the removal of chrome plating from a surface. Chrome plating is commonly applied to enhance the appearance of objects, provide corrosion resistance, improve wear resistance, and increase hardness. However, there are instances where chrome plating needs to be stripped off, such as when refurbishing or repairing parts, or when applying an alternative coating or finish.

The Process of Chrome Stripping:

1. Surface Preparation: Before starting the chrome stripping process, proper surface preparation is essential. This typically involves thorough cleaning to remove any dirt, grease, or oils present on the surface.

2. Chemical Stripping: The most common method for chrome stripping is through the use of chemical solutions. These solutions contain powerful acids or alkalis that can dissolve the chrome layer without damaging the underlying material. The part to be stripped is immersed or sprayed with the chemical solution and left for a specified period, allowing the chrome plating to be dissolved.

3. Mechanical Stripping: In some cases, mechanical methods may be employed to strip chrome plating. This technique involves using abrasive materials or sandblasting to physically remove the chrome layer from the surface.

4. Post-Treatment: After the chrome plating has been successfully stripped, it is crucial to thoroughly rinse and neutralize the surface to ensure all traces of chemicals or abrasives have been removed. Proper post-treatment processes help prevent any potential damage to subsequent coatings or finishes applied.

Applications of Chrome Stripping:

1. Part Repair and Refurbishment: Often, components with worn or damaged chrome plating require repair or refurbishment. By stripping the old layer, it becomes possible to inspect the underlying material for any flaws and undertake necessary repairs.

2. Coating Replacement: Another common application of chrome stripping in CNC machining is to replace the existing chrome coating with other coatings or finishes. Different types of surface treatments may possess specific properties like improved hardness, increased corrosion resistance, or enhanced friction characteristics, making them suitable alternatives.

3. Environmental Considerations: Chrome stripping can also play a significant role in environmental sustainability efforts. The process allows for the recycling of materials and reduces waste associated with chrome plating disposal.


Chrome stripping is an essential technique implemented in CNC machining for various reasons, including part refurbishment, coating replacement, and sustainable manufacturing practices. Understanding the process involved and its applications helps ensure the efficient utilization of this method within the realm of CNC machining. Whether it's repairing equipment or exploring alternative surface finishes, the versatility of chrome stripping contributes significantly to achieving the desired outcomes and maintaining the highest quality standards in manufacturing processes.
