Self tap monitor function in Microntech Estic handy DC Nutrunner

“Self-tap monitor function” of Microntech Estic DC Nutrunner is used when we use self-tap screws in fastening, self-tap fastening creates various problems, to identify and monitor them we have a special option in Microntech Estic Handy Controller which is called Self Tap Monitor Function. We used this option when a large amount of torque occurs like with a tapping screw or bolt at the beginning of a fastening process and exceeds SEAT torque. From START TRQ detection no Seat Torque is detected during Interval. During the time, when peak torque is held and if it jumps the maximum self-tap torque, this operation completes as NG. In addition of this process, if the peak torque, which is held when the self-tap section completes, falls below the minimum self-tap value, this operation completes as NG.

main Parameters of Self Tap Monitor Function
Estic DC Nurtunner
Following are the main Parameters of Self Tap Monitor Function:
  • INTERVAL : Self-tap interval
    This function monitors the process until set angle value from the START TRQ point (Range: 0–65000 deg Default = 10 deg).
  • TRQ MIN : Self tap torque minimum value
    In the monitor interval, this is the minimum torque value. If a detected torque falls below the setting value, self-tap LOW NG judgment stops and is displayed and output (Range: 0.00–rated torque Default = 0.00)
  • TRQ MAX : Self tap torque maximum value (TRQ MIN < TRQ MAX)
    In the monitor interval, This is the maximum torque value. If a detected torque exceeds the setting value, self-tap HIGH NG judgment stops and is displayed and output (Range: 0.00–rated torque Default = rated torque)
