WITTE Sandwich Plates

These light, strong, accurate plates can be used vertically or horizontally, with or without hovercraft.

They are a good alternative to conventional cast plates.

Witte offers three basic versions, but usually customers have their own specifications and requirements on dimensions, grid and accuracy.

 

 
 

FW plates (friction welded)

Mostly used horizontally as a lightweight base for smaller fixtures. With a total height of 100mm, surface plate thickness is 10mm, which for stability reasons limits maximum width and length of these plates to 1600x2400. Grid 100 or according to customer request.

Classic Sandwich plates in AIMg4,5Mn

Are used vertically (recommended thickness minimum 300mm) or horizontally (recommended thickness 150mm). Two surface plates each 25mm thick are screwed and or glued together using aluminum tubes giving a very rigid structure. Due to materials used, plates do not need surface treatment and are corrosion free.

Suitable for sophisticated grid patterns, accuracy acc. to customers requirements.

Used as a base for mounting exchangeable work piece supports.

Classic Sandwich plates in EN-AW-5083

Are used vertically (recommended thickness minimum 300mm) or horizontally (recommended thickness 150mm). Two surface plates each 25mm thick are screwed and/or glued together using aluminum tubes giving a very rigid structure. Plates are anodized, or hard-coated on request.

Suitable for sophisticated grid patterns, accuracy acc. to customers requirements.
Important accessories to large Classic sandwich plates are Witte's quick clamping systems integrated into the plates to allow fast, accurate and repeatable positioning of sub-plates mounted with support points.
Used as a base for mounting exchangeable work piece supports.
These plates are also available anodized black.
 Sandwich plates with hovercraft
Plates this size have to be handled and positioned in some way. This can be either using a crane and hooks or, more convenient and if the floor surface will allow, using hovercraft. The heavy duty air cushions can move over graps and ridges.

Witte supplies sandwich plates  with:

  • integrated air tanks - for movement without impeding hoses
  • friction wheel drive
  • remote control
