  skos:definition """1. The vacuum chuck is of such construction that the inside of the chuck is evacuated by a vacuum pump to reduce the internal pressure and a workpiece is held by atmospheric pressure. (https://www.kanetec.co.jp/en/pdf/043_046.pdf). 2. A vacuum chuck is a workholding device that uses atmospheric pressure to clamp a workpiece solidly against its surface. Traditional clamps apply direct force. Conversely, a vacuum chuck uses suction force created by removing air from a sealed area between the chuck and the object. This suction force carries the object tightly in place. (https://www.guangdar.com/understanding-vacuum-chuck-definition-and-applications). 3. A vacuum chuck system uses vacuum suction to hold a workpiece in place while it is being machined or worked on.

It typically consists of a steel or aluminum vacuum table that has a series of small holes drilled through it, which is then connected to a special vacuum pump for vacuum chuck.
