Description
A vacuum table holds the workpiece through the pressure difference over the active area, but the pump must be chosen on leakage, not on volume: uncovered perforated surface, porosity of the part and perimeter seals determine the flow to be guaranteed and the pull-down time. In parallel the table must be checked for deformation, because the deflection under vacuum spoils the flatness of the product.
What it includes
- Holding force as a function of the vacuum level and of the active area
- Leakage flow estimated for uncovered zones, porosity and seals
- Choice of pump and tank, with the pull-down time
- Division into zones and sizing of the manifolds
- Check of the table deflection under vacuum load to EN 1993-1-1
- Calculation report with the operating point of the system
What we need from you
- Table dimensions and hole or groove pattern
- Dimensions, mass and porosity of the part to be held
- Required vacuum level and acceptable pull-down time
- Machining forces, if the part is machined on the table
