Chrome plating is a popular technique used to enhance the appearance and durability of various metal surfaces. However, circumstances may arise where the chrome plating needs to be removed in order to achieve specific manufacturing requirements or repair damaged components. In the world of CNC machining, understanding the process of chrome plating removal becomes essential. This article outlines effective methods and considerations when removing chrome plating to ensure flawless CNC machining results.

1. The Importance of Chrome Plating Removal in CNC Machining:

CNC machining involves precise cutting, shaping, and drilling of raw materials to create intricate components with high accuracy. To accomplish this, it is crucial to have a clean, defect-free surface as a starting point. When working with an object that has been chromed, such as automotive parts or machinery components, removing the chrome plating is often necessary before performing further machining operations. Proper chrome plating removal ensures optimal adhesion between the component and subsequent coatings or treatments.

2. Methods for Removing Chrome Plating:

a. Mechanical Stripping:

One common method for removing chrome plating is mechanical stripping. It typically involves using abrasive materials like sandblasting or grinding wheels to remove the chrome layer. Care must be taken to avoid damaging the underlying material during the process, especially if the substrate is softer than the chrome plating itself. Proper protective clothing, including gloves and goggles, should be worn while carrying out these procedures.

b. Chemical Stripping:

Chemical stripping is another approach to remove chrome plating from metal surfaces. Various acid-based solutions can be used to dissolve the chrome layer carefully. However, caution should be exercised with chemical strippers, ensuring they are appropriate for use on the specific metal to prevent any adverse reactions or damage to the intended substrate.

c. Electrolysis:

Electrolysis, also known as electrochemical stripping, is an effective method for removing chrome plating. This process involves submerging the object in a solution and using electric current to separate the chromium ions from the surface. Electrolysis offers precise control over the removal process and can be customized to address specific requirements.

3. Special Considerations:

a. Safety Precautions:

When performing any chrome plating removal technique, safety precautions must be strictly followed. This includes wearing appropriate personal protective equipment (PPE) like gloves, goggles, and masks, as well as working in a well-ventilated area. Some methods, such as chemical stripping or electrolysis, may require additional safety measures due to the use of potentially hazardous substances or electrical currents.

b. Surface Preparation:

After successful chrome plating removal, thorough surface preparation is essential before commencing CNC machining processes. Adequate cleaning, degreasing, and polishing should be performed to ensure a contaminant-free and smooth starting surface that facilitates accurate machining operations.

c. Expertise:

Performing chrome plating removal requires experience and expertise to avoid damaging the component's underlying material. If unsure about the proper procedures or techniques, it is recommended to consult with professionals specializing in metal finishing or seek advice from reputable CNC machining service providers.


Chrome plating removal plays a crucial role in the realm of CNC machining by ensuring pristine surfaces for further fabrication and enhancing the adherence of coatings or treatments. Various methods, including mechanical stripping, chemical stripping, and electrolysis, offer different levels of precision and effectiveness in removing chrome plating. However, regardless of the chosen method, always prioritize safety measures and follow proper surface preparation practices to achieve impeccable results in your CNC machining projects. CNC Milling
