Making a Safer World Through Accuracy and Precision

E-DRIV® MD-Series DC Torque Control System

MD-Series DC Torque Control System


The DC control tool is a reliable torque and automation fastening system engineered for precise, accurate and repeatable torque control. The high performance torque fastening system allows manufacturers to optimize the assembly area, reduce labor costs and increase productivity. The digital screwdriver system features a built-in error-proofing data and screw counter. Multiple fastening strategies can be implemented for sensitive and/or difficult assembly joints. Increase productivity as one tool can be programmed to do the job of multiple conventional tools; saving time, maintenance cost, space & training. 

  DC Electric Fastening System for Torque Automation
  RoHS CE    NRTL      



Key Benefits

Productivity   Increase productivity with one tool instead of 2 - 8 tools. Provides a consistent repeatable process control and eliminates potential variations.
Flexibility   Easy integration into production line. Rapid reconfiguration for new production projects.
ROI   Optimum asset utilization. Tooling expense delivers favorable return of investment.
Quality   Traceability and error-proofing. Real time monitoring. Swiss DC servo motor provides precise, accurate and repeatable torque control.
I/O Interface   Digital I/O signals for communication with external devices such as PLC
Controller   Up to 15 process sequences with 10 program steps.
Memory   Collect and save all fastening data on SD memory card.
  Fastening torque data analysis (Standard Deviation, Mean, Average, CP, CPK ) with TPM (Torque Process Monitoring) Touch Screen accessory option.
