Chrome stripping is a process that involves removing chrome plating from various surfaces. It is commonly used in industries involved in repairing or refurbishing metal parts, automotive restoration, and even artwork preservation. In this article, we will delve deeper into the concept of chrome stripping and explore its relevance in relation to CNC machining.

What is CNC Machining?

CNC (Computer Numerical Control) machining refers to a manufacturing process where pre-programmed computer software controls the movement of machinery tools. This technique enables precise cutting, milling, shaping, and drilling of materials like metals, plastics, and wood, automating the production process with minimal human intervention. CNC machines are widely used across multiple industries due to their accuracy, efficiency, and flexibility.

Relevance of Chrome Stripping in CNC Machining:

Chrome stripping plays a significant role in CNC machining as it helps prepare the surfaces for further processing. The process involves the removal of existing chrome plating on components before they undergo CNC machining operations like milling or drilling. By stripping off the chrome, both the surface finish and dimensions can be corrected or modified, ensuring optimal precision during subsequent CNC processes.

Methods for Chrome Stripping:

There are several methods available for stripping chrome from surfaces, each suited to different types of applications and materials. Some common techniques include chemical stripping, mechanical stripping, and electrochemical stripping.

1. Chemical Stripping Method:
Chemical stripping involves utilizing special chemicals designed to remove chrome plating without damaging the substrate material. The components are typically immersed in a specific solution that effectively dissolves the chrome layer. Chemical stripping is often employed when precision and delicate materials are involved.

2. Mechanical Stripping Method:
Mechanical stripping employs physical forces such as grinding, sanding, or abrasive blasting to remove the chrome coating. This method is suitable for robust and durable materials where aggressive removal is necessary but may not be suitable for delicate components.

3. Electrochemical Stripping Method:
Electrochemical stripping combines chemical and electrical processes to remove chrome plating. By passing an electric current through the solution, the chrome layer is selectively dissolved, leaving behind a clean surface. This method is widely used due to its efficiency and precision.

Benefits of Chrome Stripping in CNC Machining:

1. Surface Preparation: Chrome stripping ensures that surfaces are properly prepared before CNC machining operations commence. By removing the existing chrome coating, any imperfections or irregularities can be corrected, resulting in more precise production outcomes.

2. Enhanced Adhesion: Stripping off old chrome allows for better adhesion of subsequent coatings like paint, powder coat, or additional metal finishes. Improving adhesion ensures longer-lasting finishes and increases the overall durability of machined components.

3. Dimensional Accuracy: Chrome stripping enables adjustments to dimensions, ensuring parts meet exact specifications during CNC machining. Correcting any dimensional errors beforehand guarantees precise production results.

4. Environmental Friendliness: Chrome stripping utilizing environmentally friendly methods helps reduce pollution by avoiding hazardous chemicals found in traditional chrome removal techniques.


Chrome stripping is an essential process in the world of CNC machining, playing a vital role in both surface preparation and part correction. By removing existing chrome plating, it ensures optimal precision and accuracy in subsequent CNC machining operations. Whether it involves chemical, mechanical, or electrochemical stripping methods, each approach contributes to achieving high-quality results. Embracing these techniques not only enhances manufacturing standards but also promotes environmental sustainability. CNC Milling
