Battery Operated Pistolgrip EC-Screwdriver-Image

Battery operated screw driving with the highest accuracy!

Now in pistolgrip design for assembly in space-limited areas and for high torque requirements

The more that compressed air hoses and cables are a hindrance during assembly work, the more preference is given to battery-powered EC-screwdrivers for mass-production environments. The increased performance of modern batteries also increases the application field for those tools. The proven DEPRAG precision screwdriving technology is now also available in a cordless pistolgrip design.

No matter whether screwdrivers are used in the assembly of car interiors or travel-trailers, binding air hoses and electric cables hinder the work process in space-limited areas. For those applications, the use of a cordless screwdriver can be tremendously helpful. For example, on assembly lines where a conveyor is moving, the use of battery-operated screwdriving tools provides major advantages. In the past, battery-driven screwdrivers were not very convincing, mainly because of their short life span. However, the performance of today's battery-operated screwdrivers can no longer be compared with this old technology. The DEPRAG engineers decided in favor of the latest generation of Lithium-ion rechargeable batteries for this new screwdriver series.

These new batteries have a considerably lower idle-discharge, and the dreaded memory-effect -that occurs as a result of partial charging -is non-existent. It is also important to note that the new batteries can now be fully charged in about 40 minutes.

The 36V Li-Ion battery that operates these new DEPRAG screwdrivers, offer a high energy-and performance density. The regenerative feedback of the braking-energy for the electric motor, translates into an extremely efficient and low-cost energy consumption. This efficiency and the sensor-controlled multi-level standby-mode permit a high number of screwdriving cycles per battery charge. By using high-grade EC-electric motors that excel through power-density and output-efficiency, the tool has a low weight and a long service life.

This tool series fulfills the demands for precision and allows the processing of complex screwdriving cycles that are part of today's conventional torque/angle-controlled screwdriving requirements. The tools can be programmed with eight multi-level screwdriving sequences that are already stored within the Screwdriver. The easy and quick selection and initiation of a program is done directly on the tool's display-keypad.

This Screwdriver series will consist of three different pistolgrip tools with a torque range of 0.8 -13 Nm [7-115 inch pounds] and programmable speeds from 30 -1,500 rpm. The angle-head design has a torque range of 2 Nm to 50 Nm [18 -440 inch pounds]. Due to the high shut-off accuracy, this tool series reaches a Cmk-value of ≥  1.67 and therefore meets the quality requirements demanded by the automotive industry.

The entire DEPRAG MINIMAT®-EC screwdriver family is well-known by its truly ergonomic design and this new screwdriver series is no exception. The operator comfort is assured by the low weight of the tool and an integrated directive-light, which illuminates the screw-location.

Using a Bluetooth, wireless data-transmission, the screwdriver can stay in contact with an optionally available base-station. There, a graphic user interface allows the fast and easy generating of screwdriving sequences. Additionally, it is possible to connect the base-station to a host PC that transmits screwdriver settings and can also receive and archive data received from the screwdriver. It is possible to connect up to four (4) tools to one base-station. With the new cordless screwdriver series, DEPRAG is introducing superior tools for the use with assemblies requiring process-control and where space limitation or torque is a problem. In addition, this new tool series incorporates all the other advantages of the proven MINIMAT-family.
