Laser Engraving vs. CNC Milling: What's the Difference?

When you order a custom metal card, we use two very different technologies to create it. Understanding the difference helps you design a better card.

1. CNC Milling ( The Structure)

CNC (Computer Numerical Control) is a drilling process. We use a high-speed diamond bit to physically carve out the pocket where your EMV chip sits. This ensures the chip sits "flush" with the surface, not sticking out.

2. Fiber Laser (The Design)

For your name, numbers, and artwork, we use a 50W Fiber Laser. This doesn't "print" ink. It blasts the surface of the steel with intense energy.

• Annealing: On stainless steel, we can heat the metal to turn it black without removing material. This feels smooth to the touch.
• Deep Engraving: We can also burn away material to create a texture you can feel with your fingernail.

Why it matters

Because we use lasers, your design will never fade, peel, or rub off. It is physically part of the metal.
