Smarter Assembly with Torque and Angle-Controlled Electric Screwdrivers

Torque and angle-controlled electric screwdrivers are powerful, intelligent, connected tools for Industry 4.0, reliable and ergonomic to use. These screwdrivers are critical components of the assembly process. Modern industrial assembly plants are complex systems where every component and unit must be optimized for quality, efficiency, and safety. Complete system integration is the key to efficient production. These torque-controlled screwdrivers are multifunctional smart tools, supported by connected software that ensures error-free operation for maximum productivity.

Torque-controlled electric assembly tools are a complete solution for high-quality industrial assembly of bolted or screwed components. Fully integrated and connected control and visualization systems ensure consistent precision, reliability, and quality. These electric screwdrivers, which monitor both torque and tightening angle, also address many human-factor challenges. For example:

• Integrated smart error-monitoring functions to eliminate operator mistakes, avoiding loose or missing screws.
• Sophisticated technology and connectivity for high precision across all assembly types, combined with the fastest cycle times to boost productivity.
• Advanced ergonomic designs for quiet, well-balanced tools that reduce operator fatigue and enhance productivity.

In effect, a torque-controlled screwdriver features the latest technologies to improve productivity, quality, and efficiency.

The torque-controlled electric screwdriver is the final component of a complete quality control system. This type of tool is capable of monitoring the number of turns or the angle throughout the entire tightening process, starting as soon as the operator pulls the trigger. In addition to detecting cross-threaded or damaged screws, checking the screw seating and tightening angle also ensures the complete status of the fastening element. The angle monitoring function is also used to detect missing components (such as washers), and cables/materials stuck under the screw head.

• TurboTight®: This revolutionary fastening strategy offers unmatched user comfort by allowing the tool to reduce the reaction force, significantly enhancing its ergonomics.
• TrueAngle®: This feature eliminates operator influence using a gyroscope to measure tool movements, thus increasing the accuracy of angle measurement. It allows for handheld angle-controlled tightening while eliminating operator influence. This reduces the angle window and makes common assembly issues (e.g., defective or missing components, or damaged threads) easy to identify. It also helps avoid premature stoppages and detects re-tightening. All these benefits contribute to improved quality and reduced scrap and rework costs.
• Low Reaction Tools: The latest technological advancements have led to the development of new electric screwdrivers (with or without batteries) with low reaction torque (LRT). These screwdrivers enable high tightening torques (up to 150Nm at present) to be achieved with one hand, while maintaining traceability of all screw applications. These tools are also connected and compatible with data processing systems and Industry 4.0 standards.
