The stationary electric screwdriver series 342E with mechanical shut-off clutch is the optimal solution for work stations where compressed air is not desired or there is no compressed air available. This expansion of the spindle screwdriver range has set a new standard: There is now a DEPRAG screwdriving solutions available for every application case.
The strength of the MINIMAT-E spindle screwdriver lies in the screw assembly torque range of 0.1 Nm to 4.8 Nm. High speeds of 650 up to 2000 rpm guarantee short cycle times.
The MINIMAT-E screwdriver operates using the well-established principle of the mechanical MINIMAT shut-off clutch. Using the shut-off clutch guarantees torque accuracy of 3 % standard deviation, irrespective of the screw joint.
However, in many cases even better accuracy can be achieved so that under certain conditions a machine capability index of ≥1.67 can be attained even with a tolerance requirement of ±10 %. This means that the error rate is less than 0.6 per million screw assemblies. For further enhancement of the processing reliability the screw-in depth and screwdriver shut-off can additionally be monitored.
Depending on application case very short cycle times can be achieved as this screwdriver runs at maximum speed right up to the shut-off point of the clutch. Whereas in order to reach the stated accuracy other controlled screwdrivers are subject to a speed reduction before shut-off.
The screwdriver is designed for tough industrial use with high quality, robust system components guaranteeing reliability and a long lifespan.
The maintenance free brushless EC drive provides outstanding dynamics and high maximum torque which is ideal for screw tightening.
The screwdriver is available with push-to-start or remote start PLC signal. As well as screw assembly to torque, the remote start version can carry out screw assembly to designated screw-in depth (with optional depth sensor) or a defi ned loosening procedure via reversal of the screwdriver.
The options for inserting tools and additional components such as guide sleeves or vacuum connections are designed in the same way as the DEPRAG MINIMAT pneumatic screwdriver motor size 2 so that identical accessories may be used.
