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.
