Sudong NC is a Servo Based Current-Controlled Screwdriver, the current controlled mechanism provides real time torque measurement and the servo motor with encoder tracks speed and tightening angle feedback. It can detect most screwing issues such as missing screw, over tightened screw, floating issues, screw stripped, etc. It has a 4-step programming making it capable of working on a torque speed profile providing user control over all the tightening parameters. It is an IOT compliant device capable of MES connectivity and barcode traceability.
