Vac-Mat fixtures transfer the vacuum to many suckers on a replaceable synthetic mat. Each sucker helps to hold the part flat against the fixture. The mat can be cut into by the milling tool to finish machine the edges or produce a window or pocket on the part.
What is vacuum clamping?
Vacuum clamping guarantees very short set-up times. Even components which are difficult to clamp mechanically can be easily and quickly clamped without the risk of distortion. The vacuum clamping technology enables: Clamping with short set-up times. High holding force.
How do vacuum chucks work?
Vacuum chucks rely on the atmospheric air pressure around them to push parts onto their surface. ... When a vacuum chuck is turned on the air pressure decreases below the workpiece which causes higher air pressure above the workpiece to want to fill this low pressure space below it.
