In recent years, with the continuous innovation of automotive technology, the precision requirements for parts are also constantly improving. In new energy vehicles, power devices require higher current density, which puts forward higher precision requirements for battery processing. Therefore, precision machining of automotive parts has become one of the most important research topics in the current automotive industry.

At present, through the use of high-speed motorized spindle, it is possible to carry out precision machining of auto parts through more accurate machine tool processing technology, such as precision machining for new energy auto parts, such as battery cover plate chamfer deburring, gear chamfer deburring, new energy vehicle hub deburring, etc. In particular, Japan's NAKANISHI high-speed motorized spindle, high precision, high speed characteristics make it the first choice for automotive parts precision machining.

In addition, laser soldering technology has also been widely used in precision parts processing in automobile manufacturing, which can improve connection strength and durability, reduce automobile manufacturing costs and environmental pollution.

In the mold development process, Jindi's core technologies such as "mold design simulation and processing technology" and "casting aluminum rotor mold design and manufacturing technology" have improved performance verification, dimensional accuracy and quality control. In the processing and production link, the application of "fine blanking equipment adaptive transformation technology" and "automatic precision machining technology" improves the automation level of the production line and accurately controls the flatness of the product.

In the production process of cast aluminum rotor, the application of "casting aluminum rotor forming process technology" and "the influence of asynchronous induction motor manufacturing process on NVH" effectively reduces the product porosity, improves strength, and reduces the impact of product NVH.

In general, the latest research results of precision machining of auto parts not only improve the accuracy and quality of auto parts, but also provide strong support for the development of the automotive industry.
