# Vacuum plates

## Abstract

A vacuum plate system comprises a support plate (310) formed of a plurality of support plate modules (320-380) that are supported on a base plate, and serve to transfer vacuum between vacuum apertures in the base plate and a workpiece held on the support plate (310). The support plate module (340) is formed with a plurality of circular lip seals (341) of larger size, and disposed therebetween, a plurality of lip seals (349) of smaller size. The area within each of the lip seals (341, 349) has a small hole extending through the respective support plate module, to transfer vacuum in a restricted manner. The remaining support plate modules are of a similar configuration, but with variations. In machining of a workpiece held on the support plate modules (320-280), the modules may be cut into, without risk of losing the vacuum overall holding effect on the workpiece. The specification discloses various other support plates.
