CNC machining has transformed the manufacturing industry with its precision and efficiency. One crucial aspect of this process is chrome stripping, which involves removing the chrome plating from a metal surface to achieve desired results. In this article, we will delve into the intricacies of CNC machining and explore how chrome stripping plays a pivotal role in its successful execution.

Understanding CNC Machining:

CNC (Computer Numerical Control) machining is a sophisticated technique that utilizes computerized systems to control various machining tools. It offers unparalleled precision, consistency, and flexibility compared to conventional manual machining methods. By using CAD/CAM software, designers can create intricate 3D models that are converted into instructions for CNC machines, enabling them to produce complex parts with exceptional accuracy.

The Role of Chrome Stripping in CNC Machining:

Chrome stripping refers to the removal of chrome plating from metallic surfaces before undergoing further machining processes. While chrome plating enhances the aesthetics and corrosion resistance properties, it hinders the machining process due to its hardness. Thus, chrome stripping becomes essential to prepare the material for subsequent operations like drilling, milling, or turning.

Steps Involved in Chrome Stripping:

1. Surface Preparation:
Before initiating the chrome stripping process, a thorough evaluation of the surface condition is necessary. This includes identifying any damages, scratches, or unevenness on the chrome-plated part. The surface must be cleaned meticulously to ensure effective stripping.

2. Chemical Stripping:
Chemical stripping is the most common method employed in chrome stripping. A specially formulated stripping solution is applied to the chrome-plated surface through various techniques like dipping, brushing, or spraying. The chemical reaction between the stripping solution and chrome plating gradually dissolves the layer, allowing for easy removal.

Note: Safety precautions must be taken while handling these chemicals, as they can be hazardous if mishandled. Adequate ventilation, wearing protective gear, and following manufacturer instructions are imperative.

3. Physical Stripping:
In certain cases where chemical stripping is not appropriate or sufficient, physical methods like abrasive blasting or sanding may be employed. These techniques involve using high-pressure air or mechanical tools to remove the chrome plating layer by layer until the desired surface quality is achieved.

4. Post-Stripping Surface Treatment:
Once the chrome plating has been successfully stripped, it is crucial to perform necessary post-stripping treatments to enhance the material's performance and aesthetics. This may include additional cleaning, polishing, or application of other coatings, such as nickel or zinc, for improved corrosion resistance.

Benefits of Chrome Stripping in CNC Machining:

1. Improved Machinability: By removing the chrome plating, materials become more suitable for machining operations, reducing tool wear and increasing cutting speeds.

2. Enhanced Precision: Eliminating the hardness of chrome plating allows CNC machines to achieve greater accuracy and intricate detailing during subsequent machining processes.

3. Cost Efficiency: Instead of discarding expensive chrome-plated parts, chrome stripping enables their reuse, leading to significant cost savings in manufacturing.


CNC machining has revolutionized the manufacturing industry, allowing for the production of intricate components with unparalleled precision. Chrome stripping represents a crucial step in this process, ensuring that metal parts with chrome plating can be effectively machined to meet desired specifications. By understanding the steps involved in chrome stripping and its benefits, manufacturers can optimize their CNC machining operations, leading to improved productivity and cost efficiency. CNC Milling
