Big Daishowa's outstanding tool development relies on cutting force measurement technology from Kistler

Application Cases

The role of the bolt is to tighten, and it is conceivable that the preload (clamping force) is the most important measurement parameter. However, the pre-tightening force can not be directly measured like torque. It can only be measured by indirect method. The measuring method is also varied. The traditional method includes strain gauge method and washer sensor method, while ultrasonic wave is used to measure the pre-tightening force compared with other methods. The method does have many advantages, and can achieve non-destructive measurement, real measurement, information preservation, and cost saving.
Practice and theory are the left and right legs of human knowledge learning. Recently, Xiao Yan discovered that the left leg of the domestic fastening industry has become more and more sturdy, but the right leg is somewhat thin, and the theory is more or less lacking, including Xiao Yan himself. It's time to arm yourself with theory, and there is a book that will hold you armed.

Keep a close eye on bolted joints – with test systems from Kistler

Joining two or more parts with a bolt: it sounds perfectly simple in theory, but it often presents a challenge in series assembly. The objective: to guarantee consistently high quality in a cycle throughout a lengthy period. Functional characteristics such as the friction coefficient, preloading force and torque of the bolted joint are some of the most critical quality factors in the production process. And that's why they have to be fully verified and documented – from start to finish. Highly flexible modular test systems from Kistler determine the functional characteristics of each individual fastener – from measurement and control of the bolting process through to comprehensive documentation of process parameters. The benefits: consistently increased process reliability, optimized resources and sustainable quality assurance – to ensure your success.
