1. Both CNC engraving processing and CNC milling processing adopt the milling processing principle. The main difference lies in the diameter of the tool used. Among them, the commonly used tool diameter for CNC milling is 6-40 mm, while the tool diameter for CNC engraving is 0.2-3 mm.

2. Does CNC milling can only be used for rough machining, and CNC engraving can only be used for finishing

Before answering this question, let us first understand the concept of the process.

The rough machining process requires a large amount of machining, but the finishing machining amount is small, so some people habitually regard rough machining as "heavy cutting" and finishing as "light cutting". In fact, rough machining and semi-finish machining (the picture below shows milling)

Finishing is a process concept, which represents different processing stages. Therefore, the accurate answer to this question is that CNC milling can be used for heavy cutting or light cutting, while CNC engraving can only be used for light cutting. (The picture below is finely carved and processed)

3. Can CNC precision machining be used for rough machining of steel materials?

To judge whether CNC engraving can process a certain material, it mainly depends on the size of the tool that can be used.
