CNC machining has revolutionized the manufacturing industry by providing precise and efficient production solutions. One crucial aspect of this process is chrome stripping, which plays a pivotal role in achieving high-quality finishes and bespoke designs. In this article, we will explore the intricacies of chrome stripping and its significance in the world of CNC machining.

Understanding Chrome Stripping:

Chrome stripping refers to the process of removing existing chromium plating from various surfaces or components. This is often necessary when refurbishing worn-out parts, reapplying different coatings, or altering the appearance of an object. While chrome itself offers excellent corrosion resistance and aesthetic appeal, it can pose challenges during customization or repairs. By skillfully executing the chrome stripping process, manufacturers gain greater flexibility and control over their final product's composition and presentation.

The Process of Chrome Stripping:

Chrome stripping involves multiple steps designed to remove the current chrome layer effectively. Here is a brief overview of the process:

1. Surface Preparation:
Before any actual stripping occurs, the surface must be thoroughly prepared. This typically involves cleaning the part using chemical solvents or mechanical methods such as sandblasting. Surface preparation ensures that the subsequent stripping agents can penetrate the chrome layer effectively.

2. Chromic Acid Bath:
The primary agent used for chrome stripping is chromic acid, which is both powerful and effective. The part is submerged into a bath containing chromic acid solution, and through careful monitoring and control of temperature, time, and concentration, the stripping process begins. The chromium molecules detach from the surface, enabling their subsequent removal.

3. Rinse and Inspect:
Once the desired stripping result is achieved, the part undergoes a series of rinsing phases to eliminate any remaining traces of chromic acid. A thorough inspection reveals the success of the process and determines whether additional stripping cycles are required.

4. Final Prep and Coating:
After chrome stripping, the part may require additional surface preparations before applying a new coating. This involves cleaning and activating the material for optimal adhesion. Depending on the desired aesthetic or functional requirements, various coatings such as nickel, copper, zinc, or even paint can be applied to achieve the desired outcome.

Benefits of Chrome Stripping in CNC Machining:

1. Customization: By removing existing chrome layers, CNC machining specialists gain the freedom to modify or add features to parts without limitations associated with pre-existing finishes.

2. Repair and Refurbishment: Chrome-stripping allows damaged components to be restored and reprocessed effectively without compromising their original integrity. This helps extend the lifespan of valuable components, reducing waste and costs.

3. Enhanced Design Flexibility: The ability to manipulate the finish of a part through chrome stripping opens up endless creative possibilities. CNC machinists can experiment with different coatings, textures, or colors to meet specific design requirements or customer preferences.

4. Precision Surface Preparation: Chrome stripping enables manufacturers to prepare surfaces more accurately, ensuring superior adhesion for subsequent coatings or post-processing treatments.


Chrome stripping is an essential process within CNC machining that empowers manufacturers to breathe new life into existing components, enhance customization options, and achieve remarkable designs. By understanding this pivotal technique, engineers and product designers can harness its power to create highly tailored products that perfectly align with customer needs. Embracing the art of chrome stripping sets the foundation for limitless innovation and craftsmanship in the dynamic world of CNC machining. CNC Milling
