The position control torque arm system helps manufacturers detect and eliminate costly screw-fastening errors during the assembly process. This position control system is designed to reduce the risk of improperly fastened screws, ensuring that every screw is in the correctly tightened in the correct sequence. A good tightening sequence ensures that an even preload distribution is achieved in the joint. Using a position control system is like putting the eyes and ears of a quality control manager where they are needed most - right on the assembly area. The position control system consists of a torque arm equipped with an encoder and a posi-control device. The touch posi-control system is used for programming and to track the movement of the position control torque arm.
