Basic knowledge of thread gauges

Thread gauges are essential tools used to verify if a thread meets the required specifications. A thread plug gauge is specifically designed for checking internal threads, while a thread ring gauge is used for external threads. Despite their importance, there are still many misunderstandings in the field of thread inspection, which can lead to risks and economic losses during the acceptance of threaded components. These issues may compromise the quality of mechanical products and create hidden dangers in manufacturing. To address these challenges, the United States has conducted extensive research on thread inspection. The development of the tightening thread inspection system standard (ASME standard) and the 60° thread gauge measurement uncertainty data (ASME technical report) has significantly advanced the field. As a result, U.S. thread processing and inspection technology is considered world-leading. Other countries are now looking to learn from this experience and develop their own national thread testing standards to improve the quality of their threaded products. If our technical staff can quickly learn and master these advanced thread testing systems, the quality of our thread products will improve rapidly. This will help us move away from the era of rough, unprecise thread production and enter a new phase of high-quality manufacturing. From the U.S. thread inspection system, we can also gain insights into advanced thread processing technologies. For instance, the use of differential indicator gauge detection technology can enhance machine tool and tool adjustment accuracy, allowing for more precise thread machining that closely matches theoretical dimensions. Additionally, this method can extend tool life and reduce production costs. By adopting such technologies, we can not only improve product quality but also increase efficiency and competitiveness in the global market. It’s time for us to take action and invest in better thread inspection and manufacturing practices. Editor: Hardware Business Network Information Center http://news.chinawj.com.cn
