Vacuum Tables: What To Know

Vacuum tables hold workpieces during machining. There is a perforated table top containing a vacuum chamber, as well as a vacuum pump to keep the vacuum chamber below ambient pressure.

Over the past half century, industrial engineers have used vacuum technology to hold down various materials effectively and reliably, allowing them to be printed, cut, machined, measured, coated, and adhered without the use of clamps or vacuum chucks.

How Do Vacuum Tables Work?

It works by manipulating atmospheric pressure in order to exert force on a surface against the workpiece. It increases static friction between a cutter and forces exerted by various types used today. When the atmospheric pressure reaches 29 inHg at sea level, a clamping force of approximately 14 PSI can be applied.

In order to minimize the loss of vacuum to atmospheric pressure, one must place the work upon a vacuum table and use air dams around the work. The work is put under maximum force in any altitude the table is held in, and in all axes in which the work may be machined or inspected.

There are several advantages to vacuum workholding:

  • Faster and more accurate setups.
  • Workpieces can be accessed from all sides.
  • Material handling and potential damage to the material and machine are minimized.
