Relationship and Calculation Methods of Torque, Axial Force, and Friction【Yamazen TFS】

By setting and managing the tightening torque in an appropriate manner, you can enhance the quality and safety of the product!

This document is a technical column that explains the "relationship and calculation methods of torque, axial force, and friction." It provides a detailed explanation of the interactions between torque, axial force, and friction, including the effects of torque and friction on axial force, the formulas for calculating torque and axial force, and the calculation and impact of the friction coefficient. Tightening technology may seem simple at first glance, but it is actually a very deep technical field. By correctly understanding the relationship between torque, axial force, and friction, and by setting and managing the tightening torque using appropriate methods, the quality and safety of products can be enhanced. [Contents] ■ Relationship between torque, axial force, and friction ■ Formulas for torque and axial force ■ Calculation and impact of the friction coefficient ■ Method for setting tightening torque ■ Summary ■ "Electric Nut Runner" for detecting abnormalities before seating in screw tightening *For more details, please download the PDF or feel free to contact us.

Basic Knowledge for Tightening Bolts and Screws [Yamazen TFS]

Introducing a technical column that deepens your understanding of torque and axial force, which are directly related to the quality of screw fastening!

This document is a technical column that explains the "Basic Knowledge of Torque and Axial Force during Bolt and Screw Tightening." It details the advantages of screw fastening, various definitions and points to consider for understanding fastening with screws, the relationship between torque and axial force, the friction that affects torque and axial force, and the management of tightening torque. Since the loosening of a small screw can lead to significant incidents, attention to detail is necessary. Let's deepen our basic knowledge and enjoy the benefits of screws. [Contents] ■ Advantages of screw fastening ■ Understanding fastening with screws ■ Relationship between torque and axial force ■ Friction affecting torque and axial force ■ Management of tightening torque ■ Summary *For more details, please download the PDF or feel free to contact us.

Electric Nut Runner [Yamazen TFS]

We visualize issues such as forgotten screw tightening or loose screws on-site! By visualizing the tightening flow, we solve your screw tightening problems!

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.

Screw Tightening Automation Solution [Yamazen TFS]

Improving productivity and reducing man-hours! Tightening work can be done from various angles.

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.
