✅ Non-contact, no part deformation
✅ High contrast, fine detail
✅ Fast turnaround from prototype to mass

What Are CNC Laser Engraved Parts?
CNC laser engraved parts combine two complementary manufacturing processes: CNC machining creates the precise 3D geometry of your part, while laser engraving adds permanent, high-contrast markings to the surface. This combined solution delivers fully finished, functional parts with branding, identification, or decorative features in one production workflow.
What Types of Laser Engraved CNC Parts Can Be Customized?
Our combined CNC + laser solution supports a wide range of custom parts for different industries, from industrial identification to consumer product branding:
Logo Plates
Custom branded metal plates for product branding
Nameplates
Equipment identification and asset tags
Serial Number Plates
Traceability marking for industrial parts
Control Panels
Precision marking for machine control interfaces
Machine Labels
Warning and specification labels for equipment
Automotive Trim Parts
Decorative and branded automotive components

How Laser Engraving Works on CNC Machined Parts
Laser engraving uses a focused, high-energy fiber laser beam to modify the surface of your CNC machined part. The laser’s energy vaporizes or changes the color of the material surface, creating a permanent, high-contrast mark without any physical contact with the part. This is far more durable than traditional printing or stickers, as the mark becomes part of the material itself, resistant to wear, chemicals, and high temperatures.
For metal parts, we primarily use fiber lasers (1064nm wavelength), which are perfectly absorbed by most metal materials, delivering crisp, clear marks with minimal heat affected zone. This non-contact process means we can engrave even delicate or thin parts without causing deformation or stress, which is critical for precision CNC components.
Laser Engraving vs CNC Engraving: What’s the Difference?
Both processes can add markings to your parts, but they work in completely different ways. Understanding the differences helps you choose the right solution for your project:
Materials Suitable for Laser Engraving
We support laser engraving on a wide range of CNC machined metals, each delivering unique marking results:
Common Design Considerations for Laser Engraving
To get the best engraving results for your CNC parts, our engineering team recommends keeping these design considerations in mind:
Minimum Text Size
We recommend minimum text size of 0.8mm to ensure readability, with line width of at least 0.1mm for fine details.
Heat Affected Zone
We optimize laser parameters to minimize HAZ, typically less than 0.05mm, to avoid discoloration on sensitive materials.
Surface Finish Impact
Polished surfaces may reflect laser energy differently, while anodized aluminum delivers the highest contrast results.
Engraving Depth
Standard engraving depth is 0.02-0.1mm, which is sufficient for most marking needs without affecting part strength.

Frequently Asked Questions
Can laser engraving wear off?
No. Laser engraving creates a permanent change to the material surface, either by vaporizing a thin layer or changing the material’s color. This mark is resistant to wear, chemicals, and high temperatures, unlike printing or stickers.
What materials can be laser engraved?
We support laser engraving on most metals, including aluminum (especially anodized aluminum), stainless steel, brass, titanium, and copper. We can also engrave on many plastics and other materials.
What’s the difference between laser engraving and CNC engraving?
Laser engraving is a non-contact process that uses heat to modify the surface, ideal for fine details and fast marking. CNC engraving uses a physical cutting tool, which is better for deep engraving but slower and can cause part stress.
Can anodized aluminum be laser engraved?
Yes! Anodized aluminum is one of the best materials for laser engraving. The laser removes the colored anodized layer, revealing the white aluminum underneath, creating a very high-contrast, permanent mark.
How accurate is laser engraving?
Our laser engraving system can achieve positioning accuracy down to ±0.01mm, with minimum text size of 0.8mm, making it suitable for even the most precise marking requirements.
Can you engrave logos and serial numbers?
Absolutely! We can engrave custom logos, text, serial numbers, QR codes, and even variable data for traceability, perfect for product branding and industrial part tracking.
