Definitive Guide to Router Vacuum Tables and Pumps for CNC & DIY
Vacuum Tables are often the best solution for the flat sheet work often being done on CNC Routers. You can lay an MDF spoilboard right on top of a vacuum table, and it’s porous enough to still pull a vacuum. However, unless you have a lot of vacuum available, you may want to seal part of the spoil board so the area receiving the vacuum is limited. Vacuum tables can be set up with zones that can be turned on and off with valves as well.
Understanding Vacuum Tables
Vacuum tables are essential for securing workpieces during CNC machining. They utilize atmospheric pressure to hold down parts, providing a reliable and efficient method for various materials. The technology has evolved significantly, addressing traditional limitations and enhancing usability.
