Chrome stripping is a process commonly used in the manufacturing industry, specifically in CNC machining. This article aims to explore how chrome stripping is carried out and its significance in producing high-quality CNC machined products.

CNC Machining and Its Importance:

CNC (Computer Numerical Control) machining is a widely utilized method for precise manufacturing, particularly in industries such as automotive, aerospace, and electronics. It involves using computer-controlled machines to remove material from a workpiece, resulting in highly accurate and intricate parts.

The Role of Chrome Stripping in CNC Machining:

1. Surface Preparation:
Before any machining process begins, it is essential to prepare the surface properly. Chrome stripping plays a crucial role in this by removing existing plating layers or coatings on the workpiece, ensuring a clean and uniform start. The stripped surface allows for better adhesion of subsequent coating materials, leading to improved durability and aesthetic appeal.

2. Repair and Restoration:
In some cases, CNC machined components require repair or restoration due to wear and tear or damage. Chrome stripping helps remove worn-out or damaged chrome layers, enabling effective repair work. Once the repairs are completed, the reapplication of a fresh chrome layer ensures the restored component's functionality and enhances its longevity.

3. Precision and Tolerance Enhancement:
Precision is paramount in CNC machining, where even minor inaccuracies can lead to significant issues. Chrome stripping enables technicians to refine the tolerances on machined components delicately. By precisely controlling the thickness of the chrome layer, manufacturers ensure that the final product aligns perfectly with design specifications, minimizing any deviations.

Process of Chrome Stripping in CNC Machining:

While the exact methods may vary depending on specific requirements, the general steps involved in the chrome stripping process can be outlined as follows:

1. Chemical Bath Immersion:
The workpiece is immersed in a chemical bath specifically formulated to strip chrome layers. This bath consists of chemicals that effectively dissolve the chrome plating without damaging the underlying material. The temperature, duration, and concentration of the solution are carefully controlled based on the workpiece material and desired results.

2. Electrochemical Stripping:
Electrolysis is often employed to assist in the stripping process. A direct current passes through the chemical solution, accelerating the removal of the chrome layer from the workpiece's surface. This electrochemical method ensures a more even and efficient stripping process, reducing the risk of uneven or incomplete removal.

3. Thorough Cleaning and Rinsing:
After the chrome stripping process, the workpiece is thoroughly cleaned to remove any remaining traces of chemicals. This step ensures that the stripped surface is free from contaminants before further machining or coating procedures. Proper rinsing also helps eliminate any potential negative effects on subsequent steps in the manufacturing process.

4. Surface Evaluation and Analysis:
Upon completion of chrome stripping, technicians carefully inspect the stripped surface for any signs of imperfections or inconsistencies. By conducting various tests, including visual examination, thickness measurement, and microscopic analysis, manufacturers ensure that the workpiece meets the required quality standards.


Chrome stripping plays a vital role in CNC machining, optimizing the precision, durability, and aesthetics of machined components. It serves as an essential preparatory step, providing a clean surface for subsequent coatings or repairs. Through careful control and evaluation, manufacturers can achieve superior results by incorporating chrome stripping into their CNC machining processes. CNC Milling CNC Machining
