Motor Shaft Processing Case of Dongguan Sinbo Precision

Dongguan Sinbo Precision Mechanical Co., Ltd. is a high - tech enterprise specialized in precision parts manufacturing. Since its establishment in 2013, the company has been growing continuously. It has a plant area of 34,000 square meters, more than 600 employees and nearly 500 imported processing and testing equipments. Its design and manufacturing team has over 13 years of rich experience, and is committed to providing customers with high - quality customized precision parts.

Among its numerous businesses, motor shaft processing is one of the core businesses of Sinbo Precision. As a core component in the motor system, the motor shaft plays a crucial role in power transmission. It needs to withstand huge loads and torques during operation. This puts extremely high requirements on the processing of the motor shaft. Not only do the two ends of the connection part need to be heat - treated to ensure the strength and rigidity of the material, but also the processing dimensional accuracy requirements are extremely strict, involving various processing forms such as turning, milling, drilling, hobbing, covering various working conditions before and after heat treatment.

Sinbo Precision demonstrates excellent technical strength in motor shaft processing technology. In the pre - heat treatment processing stage, advanced turning technology is adopted. High - precision lathe equipment is used to accurately process the shape of raw materials to ensure the basic dimensional accuracy of the motor shaft. For example, in the rough turning process, a 4 - axis shaft part processing solution is selected, which can effectively shorten the main processing time. At the same time, through real - time feedback from the measuring equipment, the lathe automatically compensates to ensure processing accuracy. In the milling and drilling processes, power tools are equipped to accurately complete keyway milling and drilling operations, laying the foundation for subsequent assembly and use.

The post - heat treatment processing is also a key link. For the finishing of the keyway of the drive motor shaft after heat treatment, Sinbo Precision selects suitable high - hard steel processing end mills, such as the sh360 series. This series of tools is suitable for semi - finishing and finishing of pre - hardened steel, quenched steel and other materials with a hardness of 45 - 65hrc. The cutting edge diameter specifications are reasonably set, and a high - strength, high - toughness substrate material is used with a newly developed high - hard coating, which greatly improves the tool life and realizes efficient processing. For the post - heat turning of the outer circle, the pcbn turning tool bhc200p series is used. This series of tools is suitable for continuous to medium interrupted processing of quenched steel. With a new generation of tialsin coating, it can achieve high - precision and high - surface - quality processing to meet the strict processing requirements of the outer circle of the motor shaft.

Throughout the entire processing process, the inspection link runs through. The company uses advanced laboratory professional equipment such as gear measuring centers to monitor and accurately detect various parameters of the motor shaft in real time. For example, in the processing of the important transmission part of the drum - shaped spline, the processing error of the drum - shaped amount is strictly controlled within 15 microns to ensure low noise and high transmission efficiency of the motor shaft during high - speed operation.

With its exquisite processing technology and strict quality control, the motor shaft products produced by Sinbo Precision have been highly recognized in the market. The products are not only supplied to the domestic market, but also exported to Germany, Japan, the United States, as well as countries and regions in East Asia and Africa, serving many customers in different fields. The motor shafts it produces are widely used in key fields such as new energy vehicles, civil transportation, aviation, wind power and industrial robots, providing solid component support for the 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 continuously promoting the development of the precision machinery processing industry.
