Basic knowledge of thread gauges
The thread gauge is used to check whether the thread meets the specified gauge. The thread plug gauge is used to check the internal thread, and the thread ring gauge is used to check the external thread. Due to many misunderstandings in the field of thread inspection, the basic knowledge of the thread gauge: Heavily Hot-Dip Galvanized Wire
Heavily Hot dipped Galvanized Wire
Zinc: 200-350g/m2
T/S: 380-500Mpa
Packing: plastic film inside, hessian woven bag or nylon woven outside
Shen Zhou City Hongda Hardware Products Co.,Ltd is a family owned
company, founded in 1998, loacated at Tang feng industry zone, Shen
Zhou. It has covered an area of 20 hectares, with a total asset of 20
million and more than 300 people with 80 engineering technicians, a
5-person research group, and a service group dedicated to provide the
best solutions.
The thread gauge is used to check whether the thread meets the specified gauge. The thread plug gauge is used to check the internal thread, and the thread ring gauge is used to check the external thread.
Due to many misunderstandings in the field of thread inspection, certain risks and economic requirements have brought many troubles to the acceptance of threaded products, which has buried many hidden dangers to the quality of mechanical products. In order to fundamentally reverse this passive situation, the United States is testing thread. A large number of technical studies have been carried out, and the data of the tightening thread inspection system standard (ASME standard) and the 60o thread gauge measurement uncertainty data (ASME technical report) are proposed. The thread processing and inspection technology in the United States is the world leader, and the rest of the world in the future. We will learn from the experience of the United States and develop our own national thread testing system standards to improve the quality of our country's threaded products. If our technical staff can learn and master this thread testing system technology as soon as possible, the quality of our thread products will increase rapidly. Get rid of the situation of rough thread production.
From the US thread inspection system, we can also learn some advanced thread processing technology in the United States. For example, using differential indicator gauge detection technology can improve the adjustment accuracy of machine tools and tools, and machine the thread close to the theoretical correct size. At the same time, the life of the tool is also Will increase. http://news.chinawj.com.cn Editor: (Hardware Business Network Information Center) http://news.chinawj.com.cn
