CNC machining has revolutionized the manufacturing industry through its precision and efficiency. It involves using computer-controlled machines to fabricate complex parts and components with remarkable accuracy. Among the crucial stages in the CNC machining process is chrome stripping, which plays a vital role in achieving superior results. In this article, we will explore the significance of chrome stripping in CNC machining and shed light on how it is carried out.

Understanding CNC Machining:

CNC machining encompasses various techniques used to create precise parts from different materials such as metal, plastic, or wood. By following digital design specifications, computer programming directs cutting tools or other machinery to shape the raw material. The result is an intricately crafted product that meets specific requirements.

Chrome Stripping in CNC Machining:

When it comes to achieving flawless end products in CNC machining involving metal components, chrome stripping becomes integral. Chrome plating, commonly known as chromium electroplating, is often applied to enhance resistance against corrosion, provide durability, improve aesthetic appeal, and achieve wear resistance for metal surfaces.

However, before new layers or coatings can be added during the machining process, existing chrome plating must first be removed entirely. This step ensures optimal adhesion and prevents any deficiencies that may arise from the presence of damaged or unevenly distributed chrome.

The Process of Chrome Stripping:

1. Preparing the Workpiece:
To initiate the chrome stripping process, the workpiece is properly prepared by cleaning it thoroughly. Any loose pieces or dirt particles are removed, ensuring a clean surface for effective stripping.

2. Application of Stripper Solution:
A suitable stripper solution, depending on the type of chrome plating used, is then applied to the workpiece's surface. The chosen chemical composition of the solution plays a critical role in effectively removing the plating without damaging the underlying material.

3. Soaking Period:
The workpiece is allowed to soak in the stripper solution for a specified duration, which can range from hours to days. This allows the chemical reaction to occur, loosening and dissolving the chrome plating from the substrate.

4. Mechanical Assistance:
For stubborn or thicker layers of chrome plating, mechanical assistance may be required alongside the chemical action. Techniques like scraping or sandblasting are utilized carefully to facilitate the stripping process without harming the raw material.

5. Rinse and Neutralize:
Once the desired result is achieved, the workpiece is thoroughly rinsed to remove any remnants of the stripper solution, preventing potential damage during subsequent processes. Additionally, any remaining traces of chemicals are neutralized to restore the pH balance of the surface.

6. Surface Inspection:
Finally, a comprehensive surface inspection ensures that all traces of chrome plating have been effectively removed. Proper verification provides assurance that no hidden damages or imperfections caused by incomplete stripping remain on the workpiece.


CNC machining offers exceptional precision and repeatability in manufacturing components with intricate designs and utmost accuracy. Through the critical step of chrome stripping, the foundation for superior product quality is established. By removing the existing chrome plating and ensuring a clean starting surface, CNC machinists can achieve optimal adhesion and produce flawless end products.

In this article, we've explored the significance of chrome stripping as an essential stage in the CNC machining process. Understanding the importance of this specialized technique enables manufacturers to improve the overall quality, durability, and aesthetics of their CNC-machined products. CNC Milling CNC Machining
