Vacuum is one of the most effective methods to hold down parts for CNC cutting or machining. There are two general strategies for the use of vacuum in holding parts during cutting or machining with a CNC router. You can either create seals around specific areas to be vacuum clamped in a conventional manner, or you can draw air through a broad area of a permeable bleeder board to create a more universal vacuum.
The vacuum systems that we sell and that are described here are for universal vacuum. When you purchase a universal vacuum, you will receive the vacuum blower plus components of a plumbing system that you attach to the pump and your table. In addition, you will need to machine the plenum into your table (files are included in the software) and then cover the plenum with a sacrificial bleeder board such as Ultralite MDF.

Vacuum Hold Down
A quality dust-collection system is as important as any other tool in your shop. Not only does proper dust collection ensure that your shop will stay clean, but it also protects your lungs from fine wood particles, chemicals, fungi and bacteria that have the potential to cause irritation and serious damage due to prolonged exposure.
