We would like to introduce the "Electric Nut Runner" manufactured by Atlas Copco, which we handle. It consists of three components: the "Electric Nut Runner main unit," which is the tool that actually tightens the screws; the "Controller," which issues instructions such as torque and rotation angle; and the "Computer," which is used for setting screw tightening operations and analyzing work. The Controller retrieves information about the screw tightening conditions from the computer and operates the Electric Nut Runner main unit to perform the tightening. 【For concerns like these】 ■ Forgetting to tighten screws on-site ■ Loosening of screws at customer sites ■ Damage to parts on-site *For more details, please download the PDF or feel free to contact us.

We propose a system tailored to your specifications that realizes "efficiency in assembly factories using nut runners and Techman robots." By utilizing easily movable collaborative robots, tightening operations in various directions can be performed, and position correction can be achieved in a short time using built-in cameras. Additionally, by having the robot perform the tightening, we eliminate the dependency on specific individuals for the task. There will be no missed tightenings, and the work can be carried out accurately in terms of position and order. 【Features】 ■ Reduction of productivity man-hours and labor costs ■ Stability and improvement of quality ■ Visualization *For more details, please download the PDF or feel free to contact us.

This document introduces "tightening torque and angle, and proper tightening." It explains the role of tightening torque and angle, the management of correct tightening torque and angle, the definition and importance of final tightening angle, and the definition and importance of rundown angle. Proper management of tightening torque and angle is essential for manufacturing high-quality and reliable products. [Contents (partial)] ■ Importance of tightening torque and angle ■ Types and characteristics of tightening angles ■ Conditions for proper tightening ■ Methods for managing tightening torque and angle *For more details, please download the PDF or feel free to contact us.
