VTCalc provides support for customers to find the right diameter of the suction cups by inserting the following data:
- mass to be lifted
- number of vacuum cups
- safety factor
- coefficient of friction
In the case of horizontal suction the coefficient of friction is equal to 1 while with vertical suction the value must be changed in relation to the workpiece surface to be lifted, e.g.:
0.1 for lubrificated surfaces
0.2 ÷ 0.3 for wet surfaces
0.5 for wood, glass, metal and marble
0.6 for rough surfaces
Safety factor must be equal to or greater than 2.
The result may be seen as a recommendation for the vacuum cup selection.
