Overview
System Description
The MicroTorque M screw fastening systems are servo driven microproces-
sor-controlled precision tools, based on cutting edge technology. Each tool con-
tains a servo motor, planetary gear, incremental encoder. The highly integrated
control unit MicroTorque was designed for servo control, angle measurement,
I/O-management via serial and PLC interface, and user dialog control as well as
parameter settings.
The most significant features of these assembly tools are:
• Simultaneous screw tightening and torque control.
• Freely programmable screw fastening parameters.
• Precise tightening torque, torque monitoring and measurement data docu-
mentation.
• Continuous data output for graphical display of torque vs. angle and torque
vs. time.
• No clutch for torque setting, therefore no mechanical adjustments.
• Facility for customer-specific assembly programs.
These features make the spindle particularly suitable for highly demanding as-
sembly work and guarantee exactly controlled tightening torque even under dif-
ficult conditions.
The standard screw fastening procedure passes the following steps:
• Search step (before touching the thread)
• Step 1 with angle limitation and torque window
• Step 2 with torque control and angle window
The 3 steps allow completely independent settings of rpm. Search step normally
runs at low rpm to find the thread easily. Step 1 can be run at high rpm for high
productivity and short cycle time. At Step 2 rpm is reduced to avoid exceeded
torque.
