Ensure that the extension pins are firmly located into the extension adaptor ring. Note: When
clamping onto the extension pins, ensure that the clamping load is applied centrally to the
extension pins.
14. Measuring chuck jaw clamping force.
Power-on Gripsafe and the tablet. On the tablet, connect to Gripsafe using Wi-Fi and navigate to
the Display Live Data page using the web browser. Position the Gripsafe unit in the open chuck
or vice jaws with the integrated clamping pins aligned with the centre of the Jaws. Close the
chuck or vice ensuring that the Gripsafe unit is clamped on the integrated clamping pins. Note:
Always ensure that the Gripsafe unit is inserted squarely into the chuck or vice. The static
clamping force measured in kN per jaw will be displayed on the Display Live Data page.
Do not overload the Gripsafe unit by attempting to measure forces in excess of its maximum
load rating capacity. The maximum load rating capacity is 100kN per jaw.
(1kN = 0.2248klbf = 0.102Mgf=0.1tonf)
Dynamic gripping force can be measured. The Gripsafe unit is rated up to a maximum rotational
speed of 6000rpm. Note: Never run the Gripsafe unit or work holding device in excess of its
maximum rated speed. Prior to operating the chuck at its maximum rated speed, it is advisable
to commence monitoring readings at a low speed and gradually increasing the speed observing
the fall-off in gripping force. Note: Do not allow the gripping force to fall to zero as the Gripsafe
unit could be ejected from the chuck jaws. The reduction in gripping force is proportional to the
square of the speed and causes the gripping force to fall-off steeply at high speeds.
