Designed for automated and robotic torque applications, the SD120Z-E/V off-set robotic electric screwdriver delivers precision torque control at every turn. The automation screwdriver increases productivity as one power tool can be programmed to do the job of multiple conventional assembly tools, saving time, maintenance cost, space and training. The innovative automation torque control system provides the ability to quickly transform the manufacturing area along with the flexibility to make steady product improvements for small or large production batches. The low inertial force provides smooth reaction-less operation with little G force to assembled parts. The failure of a three-cent fastener that isn't properly tightened can lead to catastrophic or latent failures. Fasteners that are insufficiently fastened can vibrate loose and excessive torque can strip threaded fasteners. The robotic assembly screwdriver provides a consistent repeatable process control and eliminates potential variations.
