Do you have the feeling that when you pass a pure electric car on the road, you will hear a noticeable sound from the electric drive?

With the increasing popularity of electric vehicles, the issue of quiet and smooth operation has become increasingly important, which has also increased the demand and application of ultra precision machining technology. Experts in the field of ultra precision machining use ultra precision technology and equipment to process the transmission shaft of electric vehicle gearboxes.

We have noticed that the demand for ultra precision machining technology has not slowed down with the trend of electric vehicle development, but rather has increased, "explained Mr. Christian Feuchter from the technical sales department of Nagel Company abroad, For traditional internal combustion engine parts, the demand for ultra precision machining is indeed decreasing, but the demand for machining electric vehicle parts, especially gearbox parts and rotating shafts, is increasing. At the same time, the demand for ultra precision machining is also constantly increasing. In addition to automotive powertrain components, the demand for ultra precision machining is also increasing for other types of driving devices, such as steering gear racks and nuts. ZF Friedrichshafen AG, an automotive component supplier, is committed to producing related parts such as transmission shafts for electric vehicles at its Tirnau factory near Pasho. This trend is confirmed by the increasing demand for ultra precision machining in the field of electric vehicles, aimed at improving the load-bearing capacity and surface accuracy of workpieces.

Unlike internal combustion engines, the operating noise of electric drive devices is inherently very low, which makes the whistling noise emitted by the bearings particularly noticeable. These noises are mainly caused by the machining ripples on the surface of the shaft neck after turning and grinding of the transmission shaft, which are inevitable during the turning and grinding processes. When the transmission components emit this noise, the corresponding friction and energy loss will also increase. Therefore, automotive component manufacturers are continuously improving their requirements for product dimensional accuracy and surface polishing quality. After all, people hope that vehicles can drive quietly on the streets instead of making strange noises. Based on this background, ultra precision machining is becoming a key technology in the production chain of electric drive system components, as only ultra precision machining can eliminate machining ripples on the surface of the journal.

With the increasing demand for ultra precision machining in automobile factories, some factories have decided to purchase new ultra precision machining centers. In the end, the Tirnow factory abroad chose Nagel's NaShaft Eco 612 equipment. After verification, this ultra precision machining equipment is the most suitable equipment for our production system, "explained the process planner in charge of the site, who also provided an overview of the automation form of this ultra precision equipment." The workpiece is fed through the top hatch of the equipment through a truss manipulator, and after completing the ultra precision machining, the workpiece is fed into the subsequent automatic transmission chain system. Mr. Christian Feuchter confidently stated, "This ultra precision machine is a highly flexible equipment platform with modular design, making it a highly cost-effective ultra precision machining solution.

With the popularization of ultra precision technology, Yuzhun Super is also providing ultra precision solutions for some cooperative car companies! Users can also choose according to their needs
