Hangzhou shaft processing technology

Shaft parts are one of the common typical parts. The manufacturing process of Hangzhou shaft machining parts is directly related to the quality of the workpiece, labor productivity and economic benefits. According to the different structure of shaft parts, it can be generally divided into three types: optical shaft, step shaft and special-shaped shaft; it is mainly used to support transmission parts, transmit torque and bear load. Shaft parts are rotating parts whose length is greater than the diameter, and are generally composed of the outer cylindrical surface, conical surface, inner hole and thread of the concentric shaft and the corresponding end surface.



In the processing of shaft parts, necessary heat treatment procedures should be arranged to ensure its mechanical properties and processing accuracy, and to improve the machinability of the workpiece. Generally, the normalizing process is arranged after the forging of the blank, and the quenching and tempering is arranged after the rough machining, in order to eliminate the stress generated after the rough machining and obtain good comprehensive mechanical properties. The quenching process is arranged before the grinding process. The center hole is the positioning reference used in the whole process of shaft parts processing, and its quality has a significant impact on the machining accuracy. Therefore, it is necessary to arrange the process of training center hole. The training center hole is generally pressurized with diamond or cemented carbide tips on a lathe. For hollow shafts, in order to be able to use the top hole for positioning, a taper sleeve mandrel or taper plug with a top hole is generally used. If the outer circle and the taper hole need to be processed multiple times and based on each other, when reinstalling the taper plug or mandrel, the center hole must be aligned according to the outer circle or re-grinding.

In short, the promotion and application of CNC machining technology in my country is a huge revolution in the machinery manufacturing industry, which has effectively promoted the development of the current level of machinery manufacturing. With the continuous development of CNC technology and the expansion of application fields, CNC machining Technology is playing an increasingly important role in the development of some important industries of the national economy and people's livelihood, such as computers, automobiles, and medical industries.
