GRIP clamping (first processing)
Pull-down clamping with GRIP
+ clamping travel approx. 1 mm (red area)
+ tilt movement when clamping approx. till 2.5°
+ stamping jaws are clinging
Clamping area (applies to GRIP and FINISH)
+ MONO: 6...108 mm
+ DUO: 106...200 mm (at hole grid 50 mm)
+ DUO: 126...220 mm (at hole grid 40 mm)
Clamping depth (applies to GRIP and FINISH)
+ 6 mm (as in image; standard)
+ 3 mm (with spacer; only possible on standard clamping)
Hole matrix (applies to GRIP and FINISH)
+ 40 mm (like presented screws)
+ 50 mm
+ longitudinal and transversal
Here: processing of bars, loosening after final processing
adaptable to zero point clamping system
2 positioning holes for precision mounting
Tightened screws max. 37Nm, Clamping force max. 16 kN / jaw
