Vilmill&Vacuum
Partners for high-speed cutting of aluminium and plastics
If your job is to cut lots of small parts out of one large part the
combination of vacuum and Vilmill is what you need.
Vilmill is a vacuum system comprising of a fleece-like, coated
foil, a specially equipped vacuum chuck and a powerful pump
system for vacuum supply.
The Vilmill foil is mounted between chuck and part. The
warmth created during cutting causes the surface coating to
melt and sticks the part to the chuck.
The vacuum is effective through the Vilmill foil, which at the
same time acts as a puffer. The accurately balanced permeability
of Vilmill foil increases the efficiency of vacuum chucks
and reduces vacuum consumption.
Especially when cutting out small parts Vilmill offers additional
security through the adherence effect. It greatly simplifies removal
of small finished parts from the machine.
For maximum cutting speeds a thin layer of material should
remain in order to use the complete part surface under vacuum
until the last cut is made.
Vilmill is suitable for aluminium or plastic sheets up to 15mm
thick. Only dry machining is possible and the working range in
Z axis must be high enough to integrate a vacuum chuck.
