In the realm of CNC machining, chrome stripping plays a critical role in achieving impeccable precision and flawless finished products. This process involves the removal of chrome plating from various components and parts to prepare them for further manufacturing processes. Whether you are familiar with CNC machining or just getting started, understanding the significance of chrome stripping is essential in ensuring exceptional results. In this article, we will delve into the intricacies of CNC machining and explore how chrome stripping can contribute to producing top-quality products.

CNC Machining – Mastering Precision Engineering:

CNC (Computer Numerical Control) machining revolutionized the manufacturing industry by automating traditional machining methods. With unrivaled precision and incredible efficiency, CNC machines have become indispensable across multiple sectors ranging from aerospace to automotive.

The CNC machining process involves utilizing computer-controlled tools and equipment to precisely shape raw materials, such as metals, plastics, and composites. It encompasses a range of operations, including cutting, milling, drilling, and turning, that fabricate intricate designs and complex geometries.

Chrome Plating and Its Significance:

Chrome plating refers to the electroplating process wherein a thin layer of chromium is deposited onto the surface of metal objects. This technique not only enhances the durability and corrosion resistance of the base material but also imparts an aesthetic appeal. The application of chrome plating finds extensive use in industries where components need to withstand harsh environmental conditions while maintaining their visual allure.

Why Chrome Stripping:

While chrome plating offers numerous benefits, there are instances when it becomes necessary to remove the plated layer during the CNC machining process. Chrome stripping serves several purposes, primarily related to subsequent operations or repairs required on the part's surface.

1. Surface Preparation:
Prior to undertaking any additional machining operations, chrome stripping ensures proper adhesion of coatings, paints, or other finishes applied to the component. By eliminating the chrome layer, subsequent processes bond more effectively to the base material, resulting in enhanced overall durability.

2. Dimensional Accuracy:
In CNC machining, precision is paramount. As chrome plating typically adds a few microns of thickness to the surface, stripping it becomes essential when maintaining strict tolerances or making intricate adjustments. Chrome stripping guarantees accurate dimensions and avoids potential manufacturing hiccups caused by insufficient clearance.

3. Recoating Over Plated Parts:
Often, components may require recoating after being stripped of their original chrome coating. This occurs commonly due to desired changes in functionality, appearance, or improved longevity. Here, the capability to strip chrome proficiently plays a pivotal role in ensuring optimal results during subsequent coatings.

Chrome Stripping Techniques:

Several methods are commonly employed for removing chrome plating from machined parts. Some widely used techniques include:

1. Mechanical Stripping:
Mechanical chrome stripping involves the physical abrasion or grinding of the plated surface using specialized tools and equipment. Depending on the requirements, this method offers excellent control over the extent of stripping required. However, it necessitates skilled operators to safeguard against unintentionally damaging the component.

2. Chemical Stripping:
Chemical stripping employs an array of chemical solutions specifically formulated to dissolve the chrome layer. While effective, this technique demands careful handling and precise application to avoid any harm to the underlying material. Experienced professionals employ various acid-based chemicals known for their compatibility with specific metals.


CNC machining has transformed modern manufacturing, providing unparalleled accuracy and efficiency. Within this expansive realm, the role of chrome stripping should never be underestimated. By understanding why and how chrome stripping contributes to the production process, manufacturers can ensure superior quality products that meet stringent standards. So, whether you're designing automotive parts or crafting aerospace components, mastering the art of chrome stripping is indispensable for achieving excellence in CNC machining. CNC Milling
