Chrome stripping is a critical process in the world of CNC machining. It involves removing chromium plating from a surface, either to repair or reshape the object. This article delves into the significance of chrome stripping and how it contributes to achieving superior results in CNC machining. We will explore various aspects related to this technique and discuss effective methods used to produce impeccable products.

1. Understanding CNC Machining:
CNC (Computer Numerical Control) machining is a modern manufacturing method that utilizes pre-programmed computer software to control the movement of machine tools. The process allows for precise cutting, shaping, and forming of various materials, such as metal, plastic, wood, and more. Each component plays a vital role in enhancing product efficiency and quality.

2. Importance of Chrome Stripping:
In CNC machining, chrome stripping serves multiple purposes. Firstly, it helps restore damaged components by removing old or worn-out chrome plating, ensuring the surface is free from imperfections before further processing. Secondly, it facilitates reshaping or modifying existing parts, enabling manufacturers to achieve intricate designs and meet specific customer requirements. Therefore, proper chrome stripping techniques are crucial for optimal machining outcomes.

3. Methods for Effective Chrome Stripping:
a) Mechanical Grinding and Sanding: One of the most common methods employed for chrome stripping is mechanical grinding and sanding. Industrial-grade abrasive materials, such as sandpaper or diamond disks, are utilized to scrape off the thin layer of chrome plating without damaging the underlying material. This technique requires precision and expertise to avoid excessive material removal.

b) Chemical Stripping: Chemical solutions specifically formulated to remove chrome plating are widely used in industrial settings. These substances actively dissolve the chromium coating, making the process less time-consuming compared to mechanical methods. However, careful handling and adherence to safety protocols are imperative due to the potential hazards associated with chemical stripping.

c) Electrolytic Stripping: This method employs an electric current to strip chrome plating from the target surface. The object is submerged in a specialized electrolyte solution, and controlled electrical charges aid in dislodging the chromium layer. Electrolytic stripping offers exceptional control and precision while minimizing distortion or damage to the underlying material.

d) Thermal Stripping: In certain cases, heating the part to high temperatures can cause the chrome plating to oxidize and degrade, thereby enabling easy removal. However, thermal stripping should be approached cautiously, as excessive heat could impact the structural integrity of the component or alter its metallurgical properties.

4. Ensuring Quality and Precision:
a) Surface Preparation: Prior to chrome stripping, thorough cleaning of the surface is essential. Any contaminants, greases, or residues need to be removed to achieve optimal results during the stripping process.

b) Skillful Execution: Chrome stripping requires skilled technicians who understand the intricacies of CNC machining. Their proficiency ensures precise stripping without damaging the components, resulting in excellent surface quality.

c) Post-Stripping Processes: After chrome stripping, it is vital to conduct subsequent treatments such as polishing, deburring, and passivation, depending on the requirements of the final product. These steps contribute to enhancing surface aesthetics, corrosion resistance, and overall functionality.


Chrome stripping plays a crucial role in achieving superior outcomes in CNC machining. By understanding various aspects related to this technique and employing effective methods discussed above, manufacturers can ensure high-quality products that meet customer expectations. Though each stripping technique has its advantages and considerations, investing in highly skilled professionals ensures efficient processing and impeccable surface finishes. Embracing reliable chrome stripping practices allows CNC machining to thrive by offering remarkable precision, versatility, and innovation across industries. CNC Milling CNC Machining
