New Size 1 Screwdriver Spindles

The new DEPRAG size-1 Screwdriver Spindles now have the prefix 347-…

The improvements made are similar to the changes made to the size-1 handheld Screwdrivers, namely increased accuracy of the clutch and improved longevity of the gear parts. Now, all size-1 Screwdriver Spindles have the same length, no matter the model number, gear rotation or reversibility option. The goal was to simplify the exchange of all size-1 spindles. While we were successful in reaching that goal, we unfortunately had to change the overall length of the new spindles. Currently, we are working on a refit kit so that the overall length of the new spindles can be made identical to the overall length of the old style spindles. Generally, such a change over is only needed if multiple spindles are mounted in one assembly unit. If only one spindle is integrated, then an adjustment of the cylinder should be sufficient to equalize the length. Another improvement is the stroke increase from 20-mm to 30-mm, giving the new tool much more flexibility.

Welcome to this edition of the DEPRAG New Product Introduction.

TRANSDUCER SPINDLES – SIZE 1
N E W Screwdriver Spindle Size-1 with inline torque sensor	DEPRAG is proud to announce a new SIZE-1 Screwdriver Spindle with integrated Torque Transducer. The torque transducer is based on a strain-gauge technology, which obtains the torque values by measuring the reaction torque of the gearing. The transducer is now – when compared to the Piezo torque sensors used so far – fully integrated into the screwdriver spindle, which eliminates errors caused by an external force. The transducer connection is integrated with the guide bolt above the drivers’ mounting area. This provides for an easier access and further protects against damage. Due to this connection change, the new spindles can be mounted into the same screwdriver fixtures as our standard- or reversible sixe-1 spindles. In the past, the disadvantage of the strain-gage system, when compared to the Piezo technology, was the generally smaller measuring range. However, this disadvantage no longer exists, because the transducers torque range roughly corresponds to the tools torque range. Therefore, the screwdriver’s function is not limited in any way. The measuring systems speed does not depend on the transducer system, but on the mass to be accelerated and the torque monitor used. Compared to the previous supplier measuring screwdrivers, we are now able to minimize the mass to be accelerated due to the mechanical setup, so that even in highly dynamic applications (hard screw joint and high speed), realistic and accurate measuring results will be achieved. The precision level of the integrated transducer is less than 1% standard deviation. For more technical specifications as well as dimensions etc., please use the following LINK to view a product specification sheet. As you can see on the specification sheet, the minimum torque for the new size-1 transducer integrated spindle is 0.4 Nm, which corresponds to 0.34 inch pounds. The spindles are available in many different designs, such as right-rotation, left-rotation, remote start and any combination thereof. The corresponding Torque Measuring Instrument, Model No. ME1000-DMS is also available effective immediately. This measuring instrument is based on the same principles of all other DEPRAG measuring units. Another very advantageous item is that the cost of this new type of tool is much lower when compared to a standard Piezo Screwdriver Spindle.
