CNC machining has revolutionized the manufacturing industry, allowing for precise and efficient production of a wide range of products. One essential process in CNC machining is chrome stripping. In this article, we will delve into the intricacies of CNC machining, with a specific focus on chrome stripping. We will explore how it is used to produce intricate parts, highlight its benefits, and shed light on why it is crucial in various industries.

Understanding Chrome Stripping:

Chrome stripping is the process of removing chrome plating from a surface using chemical solutions or electroplating methods. It is often a necessary step before re-plating, refurbishing, or repurposing the object. While this article primarily concentrates on chrome stripping in the context of CNC machining, the process is common in automotive, aerospace, and other industries that extensively use chromed components.

The Role of CNC Machining in Chrome Stripping:

CNC machining plays a vital role in the chrome stripping process. With its computer-controlled precision, CNC machines can efficiently strip even the most intricate and delicate surfaces without causing damage. This level of accuracy ensures that only the chrome layer is removed while preserving the underlying material's integrity.

The Production Process:

To produce chrome-stripped components, CNC machining utilizes various techniques depending on the object's size, shape, and complexity. Here are three commonly employed methods:

1. Chemical Deposition/Liquid Bath:
This method involves immersing the component in a bath of specialized chemicals. The chemical solution dissolves the chrome layer, which then needs to be thoroughly rinsed off to prevent any residual traces. CNC machines help automate this stage, ensuring consistent results across multiple objects.

2. Electrolytic Stripping:
In electrolytic stripping, an electric current is passed through an electrolyte solution containing the component to be stripped. The current causes ions to migrate, effectively removing the chrome from the surface. CNC machines are used to precisely control the voltage and time required for the stripping process.

3. Mechanical Stripping:
For larger components or surfaces unsuitable for immersion or electrolysis, mechanical stripping techniques are employed. This involves using abrasive materials like sandpaper or abrasive brushes to physically remove the chrome layer. CNC machining aids in achieving uniformity and controlled precision during this process.

Benefits of Chrome Stripping:

1. Restoration and Refurbishment:
Chrome stripping is frequently utilized in restoration projects where old or damaged chromed parts need refurbishing. By removing the worn-out chrome layer, CNC machining ensures a pristine base for re-plating, giving new life to vintage parts while maintaining their structural integrity.

2. Precise Re-sizing:
In some instances, chromed objects may require resizing due to wear, damage, or design modifications. By stripping off the existing chrome layer with CNC machining, precise modifications can be made, ensuring an accurate fit once plated again.

3. Improved Aesthetics:
Often, manufacturers use chrome plating to enhance the visual appeal of products. However, in certain cases, such as automotive trim or customized applications, the original chrome might not align with the desired aesthetic. By incorporating CNC machining and chrome stripping, these parts can be personalized to match individual preferences or branding requirements.


CNC machining and chrome stripping go hand in hand for efficient and accurate production processes. Whether it's restoring vintage pieces, resizing components, or enhancing aesthetics, chrome stripping plays a crucial role in various industries. The precise nature of CNC machining ensures that the chrome layer is removed without compromising the object's quality.

As technology continues to advance, CNC machining will remain at the forefront of manufacturing processes, empowering businesses to create intricate and visually appealing designs. From automotive to aerospace, the utilization of CNC machining and chrome stripping guarantees high-quality results, reinforcing its significance in modern industrial practices. CNC Milling
