The flexible NANOMAT-EC/MICROMAT-EC/MINIMAT-EC screwdrivers for the highest quality demands allow the free programming of the screw tightening process. Within the power range of the selected tool, the torque value, speed, stand-by and direction of rotation can be adjusted individually to the assembly requirement. Outstanding features of stationary EC screwdrivers are their high torque precision and the large range of control functions – perfect conditions for process security and control on highest level.
The brushless electric motors provide low maintenance operation. They are ideally suited for the tightening of screws due to their outstanding dynamics and an achievement of high peak torque values.
The integrated torque control – based upon precise measurement of the motor current along with the evaluation of other dynamic factors – as well as angle measurement, allows precise control of multistage screw-driving processes and documentation of the resulting values.
The DEPRAG screwdrivers based on EC technology enable a torque accuracy of <2 % standard deviation, which can be relied upon after millions of cycles.
Thus, a Cmk value of ≥1.67 with a tolerance requirement of ±10 % in reference to 6 Sigma is reached. A Cmk value of 1.67 means that the error rate is less than 0.6 per million screw assemblies.
The DEPRAG sequence controller AST6 is the ideal controller for stationary screw assemblies in combination with the tried and tested DEPRAG EC screwdrivers of the NANOMAT-EC, MICROMAT-EC and MINIMAT-EC (size 22) series within a torque range of 0.02 Nm - 0.2 Nm.
When choosing the option ASTi6-1 for integration into the switch cabinet, the software panel DAST can be used for operation and visualisation of the controller. In hat case the system controller additionally provides the range of functions available on the AST6-1 display.
The DEPRAG controller AST11 is the ideal sequence controller for manual and stationary screw assemblies together with the tried and tested DEPRAG EC screwdrivers MICROMAT-EC and MINIMAT-EC.
