Measuring arms upside down
Witte, manufacturer of modular fixturing systems, is presenting a new product for mounting mobile
measuring arms – a Vacuum-Disc.
Special adapters enable measuring arms of almost all manufacturers to be used independently on the
vacuum chucks i.e. without any supply lines.
Currently measuring arms must be mounted mechanically on to base plates or structures. Often the
mobile arms are equipped with magnetic adapters so they can be positioned on steel plates.
The new vacuum disk offers versatile and flexible application possibilities. Measuring arms can be
used on almost all kinds of surfaces as long as a diameter of 300mm is available.
A special vacuum seal around the perimeter as well as a 3 point support for alignment to surface
geometry enable applications on strongly convex surfaces in all positions. It is even possible to use it
upside down.
Vacuum supply is via a battery operated pump, supply includes rechargeable battery. Regular repumping
of vacuum during use ensures reliable stability. Vacuum supply and battery condition are
monitored with a visual and acoustic signal.
