英文版:Motor Shaft Processing Case of Dongguan Sinbo Precision
Dongguan Sinbo Precision Mechanical Co., Ltd., a high - tech enterprise specializing in precision parts manufacturing, has made a remarkable mark in the industry since its establishment in 2013. The company occupies a modern factory area of 34,000 square meters and has a professional team of over 600 people. Equipped with nearly 500 imported advanced processing and testing equipments, its design and manufacturing team has accumulated more than 13 years of rich experience. Leveraging these advantages, the company is committed to providing high - quality customized precision parts for global customers.
The motor shaft processing business holds a significant position among Sinbo Precision's numerous core businesses. As a crucial component of the motor system, the motor shaft shoulders the heavy responsibility of power transmission. During the operation of the motor, it has to withstand huge loads and torques. This requires that not only the connection parts at both ends of the motor shaft need to undergo strict heat treatment to ensure that the material has sufficient strength and rigidity, but also the processing dimensional accuracy must meet extremely strict standards. Its processing process covers various complex technologies such as turning, milling, drilling, and hobbing, and involves fine processing under different working conditions before and after heat treatment.
In the pre - heat treatment processing stage, Sinbo Precision demonstrates outstanding technical strength. Taking the turning process as an example, the company uses high - precision lathe equipment to precisely shape the raw materials, ensuring the accuracy of the basic dimensions of the motor shaft. In the rough turning process, a 4 - axis shaft part processing solution is adopted, which significantly shortens the main processing time. At the same time, with the real - time feedback from the measuring equipment, the lathe can automatically compensate for errors, thus stably ensuring the processing accuracy. In the milling and drilling processes, advanced power tools are equipped to accurately complete keyway milling and drilling operations, laying a solid foundation for subsequent assembly and use.
The post - heat treatment processing is also a key link that determines the quality of the motor shaft. For the finishing of the keyway of the drive motor shaft after heat treatment, Sinbo Precision carefully selects suitable high - hard steel processing end mills, such as the sh360 series. This series of tools is specially designed for semi - finishing and finishing of pre - hardened steel, quenched steel and other materials with a hardness of 45 - 65hrc. Its cutting edge diameter specifications are carefully designed, and it is combined with a high - strength, high - toughness substrate material and a newly developed high - hard coating, which significantly improves the tool life and achieves efficient and high - quality processing. In the post - heat turning of the outer circle, the company uses the pcbn turning tool bhc200p series. This series of tools is good at continuous to medium interrupted processing of quenched steel. With the new generation of tialsin coating, it can achieve high - precision and high - surface - quality processing effects, perfectly meeting the strict processing requirements of the outer circle of the motor shaft.
Quality inspection runs through the entire process of motor shaft processing. Sinbo Precision relies on advanced laboratory professional equipment such as gear measuring centers to monitor and accurately detect various parameters of the motor shaft in real time. Taking the processing of the crucial transmission part of the drum - shaped spline as an example, the company strictly controls the processing error of the drum - shaped amount within 15 microns. This accuracy is much higher than the industry standard, effectively ensuring that the motor shaft can maintain stable performance with low noise and high transmission efficiency during high - speed operation.
With its exquisite processing technology and strict quality control system, the motor shaft products produced by Sinbo Precision have won widespread acclaim in the market. The products are not only popular in the domestic market but also successfully exported to many countries and regions such as Germany, Japan, the United States, as well as East Asia and Africa, serving many customers in different fields. Its motor shaft products are widely used in key industries such as new energy vehicles, civil transportation, aviation, wind power and industrial robots, providing solid and reliable component support for the technological upgrading and development of various industries.
Through continuous technological innovation and process optimization, Sinbo Precision has established a good reputation in the motor shaft processing field, becoming a trusted partner of many customers and strongly promoting the progress and development of the precision machinery processing industry.
