Can 120w spindle motor engrave aluminium plate?

Can. 

Aluminium plates can be processed, but the efficiency will be low and it is difficult to get ideal processing results. If you need to process thicker aluminium plates or need high precision machining results, it is recommended to use a spindle motor with higher power to improve machining efficiency and quality. At the same time, you need to choose the right aluminium plate material and processing tools, and follow the correct processing technology and safety norms.120W spindle motor generally refers to the spindle motor power of the engraving machine or CNC machine tool, and this power is low for processing aluminium plate.
