CNC and lasers are both used to engrave and there are quite a few differences between the two methods. A CNC machine uses a spindle that rotates and an end mill attachment that digs into the material that you’re engraving. A laser on the other hand just heats and vaporizes the surface of the material which creates the engraving. WHen it comes to accuracy, a laser is typically a little bit more accurate and can create higher resolution engravings with both dark and light contrast.

Key Takeaways:

• A CNC machine uses a spindle that rotates and has an end mill attachment to dig into the material.
• A laser uses a higher energy laser that heats and vaporizes the surface of materials to create an engraving.
• A CNC machine can engrave basically any material whereas a laser has to be picked according to the material you’re using.

“Both techniques provide high material flexibility, and the ability to automate the process makes them ideal for large-scale production.”
