About GSK tightening setting additional items
①
Judgment area
You set the area value to be used for judging screw defects.
Calculation of area value is obtained by integral calculation on torque and angle curve
during Pre-tightening cycle (option setting item in case of Real tightening).
With the tightening waveform of the automatic measurement item in the setting software,
you can check the waveform used for this calculation.
To see this waveform, you select "Extended waveform".
②
Smooth tightening
This tightening controls the rotational speed steplessly.
You can set this tightening method by the option of the final tightening cycle.
By setting initial speed and the speed at the cutting torque,
the rotation speed changes steplessly according to the change of torque.
