The size of vacuum pump needed for a CNC machine depends on the size of your vacuum table and the material being held. Generally, for small CNC routers, a pump with a flow rate of 5–10 CFM (cubic feet per minute) is sufficient, while larger machines may require 20 CFM or more. Always ensure the pump can maintain adequate vacuum pressure (typically 20–25 inHg) for your specific application.
