Application examples
Modular clamping system from lot size 1, with extremely good accessibility
MONO: Clamping cube, flying on 4th axis MONO: Clamping module on 4th/5th axis 3 identical workpieces, processed from 5 sides (depending on workpiece and accessibility)
3 different workpieces, 1x in two clampings and 2x in one clamping, finally processed
MONO: Clamping cube on 4th axis
MONO and DUO: Clamping yoke on 4th axis two different workpieces, MONO clamping on bottom, DUO clamping on top
112 workpieces in one clamping, finally processed – unmanned operating time approx. 3.3 hours
