In the realm of manufacturing, CNC (Computer Numerical Control) machining has revolutionized the production process for various industries. By utilizing advanced software and automated machinery, CNC machining allows for precise and efficient fabrication of a wide range of products. This article delves into the fascinating world of CNC machining while specifically focusing on one crucial process known as chrome stripping. We will explore what chrome stripping is, its significance in the manufacturing process, and the methods involved in producing high-quality stripped parts.

Understanding Chrome Stripping:

Chrome stripping refers to the removal of chromium plating from a surface, commonly seen in automotive parts, kitchen appliances, plumbing fixtures, and various industrial components. While chrome plating provides excellent corrosion resistance, it may require removal due to damage, wear, or the need for re-plating. The primary objective of chrome stripping is to prepare the part for further processes like polishing, painting, or re-plating.

Significance of Chrome Stripping in Manufacturing:

1. Surface Preparation:
Chrome stripping becomes necessary when manufacturers need to work with bare metal surfaces during subsequent manufacturing stages. Proper surface preparation ensures optimal adhesion of paints, coatings, or new plating materials, resulting in enhanced durability and an aesthetically pleasing finish.

2. Restoration and Reconditioning:
For older or worn-out products, chrome stripping enables restoration or reconditioning by removing the damaged plating layer. Once the stripping process is complete, any underlying flaws can be addressed, leading to improved functionality and overall attractiveness of the product.

Methods Involved in Chrome Stripping:

1. Electrolytic Method:
The most common method employed for chrome stripping is electrolysis. In this process, the chrome-plated part acts as the positive electrode (anode), submerged in a tank filled with a suitable stripping solution. A negatively charged cathode attracts the chromium ions, effectively removing the plating layer. This method offers precise control over the stripping process and is widely used in industrial setups.

2. Acid-based Stripping:
Acidic solutions, such as sulfuric or hydrochloric acid, can also be utilized for chrome stripping. However, these methods require careful handling due to safety concerns. Acid-based stripping offers a quick means of removal but demands expertise to prevent damage to the underlying metal surface.

3. Mechanical Stripping:
Moreover, mechanical methods like abrasive blasting using media such as sand, glass beads, or plastic particles can be employed for removing chrome plating. These techniques are typically less popular than chemical or electrolytic methods, as they may cause physical damage or leave residual materials on the stripped surfaces.

CNC Machining's Role in Chrome Stripping:

CNC machining plays a vital role throughout the entire chrome stripping process. The use of computer-controlled machinery ensures precision, consistency, and efficient operation during stripping, preparation, and subsequent manufacturing stages. CNC milling machines enable accurate measurement and customization of tooling required for effective stripping, while CNC lathes facilitate seamless processing of complex component geometries.


Chrome stripping through CNC machining represents an essential step in the production cycle, allowing manufacturers to restore, recondition, or prepare metal parts for further processes. Whether it involves removing damaged plating or preparing surfaces for refinishing or recoating, chrome stripping ensures the longevity, functionality, and overall durability of various products. By harnessing the power of CNC machining technology, manufacturers can achieve precise and consistent results, empowering them to deliver high-quality products that meet industry standards and customer expectations.
