At the recent April 2023 Shanghai Auto Show, General Manager Feng Xingya of GAC Group told reporters that the company initially plans to no longer produce traditional fuel vehicles by 2025 and no longer sell pure fuel vehicles by 2028.

In fact, at this year's Shanghai Auto Show, many traditional fuel vehicle companies have brought "electricity" to the stage and embraced new changes. Several companies related to the industrial chain have stated that the main engine manufacturers began laying out new energy core components as early as 10 years ago. During an interview with reporters from Yuzhun Precision, staff from international component giant Bosch stated: "The accessories exhibited by the company at this auto show are all new energy vehicle accessories, and fuel vehicle accessories will no longer be displayed." The promotion of fuel vehicles is to remove inventory and bring "electricity" to embrace new changes. Nowadays, young people are more willing to accept quiet, environmentally friendly, and energy-saving new energy vehicles. At the same time, "joint venture brands have significantly accelerated the pace of 'electrification' and launched new new energy models. Joint venture brands pay more attention to resource integration and fully utilize brand advantages to participate in 'electrification' competition," said an automotive industry insider in an interview.

At this year's Shanghai Auto Show, luxury brands led by Mercedes Benz, BMW, and Audi have launched multiple pure electric products. Among them, Mercedes Benz debuted with 1 global debut, 5 Chinese debut, and 7 27 heavyweight models launched in China. Mercedes Maybach's first mass-produced pure electric model - the all-new Mercedes Maybach EQS pure electric SUV makes its global debut. BMW Group debuted with its strongest lineup of electric products in history.

The models exhibited by the company this time are mainly fuel powered vehicles, and the discounts are very strong. "A staff member from Guangzhou Honda told reporters," The price reduction of fuel powered vehicles will not continue. With the end of destocking, it is difficult to lower the price of new models. New energy vehicles sell well in cities with limited license plates, but fuel powered vehicles still dominate in other cities, and hybrid low fuel consumption models are becoming increasingly popular

At the Dongfeng Citroen booth, the sales manager told reporters that the models exhibited by the company at this auto show were all gasoline powered vehicles. At present, most joint venture car companies are improving fuel vehicles instead of transitioning to new energy vehicles, and cost is the main issue

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. The overall trend of electric vehicles will be a significant reduction in the number of metal parts, but when machining automotive parts, the requirements for higher quality surface finish and tolerances will increase with the increase in part complexity. Enterprises supplying original equipment manufacturers in the automotive industry need to diversify their customer base and seek other industries to ensure that production capacity does not suffer catastrophic losses. The power battery, chassis, casing, touch screen, motor, and motor of new energy vehicles all involve precision machining. The construction of new energy vehicle production lines has generated a large demand for precision machining centers.

Combining with the upgrading of the automotive industry, precision grinding is one of the most representative technological routes. Unlike internal combustion engines, the operating noise of electric vehicle electric drive devices after ultra precision treatment is very low, which makes the whistling noise emitted by the bearings become particularly obvious. These noises are mainly caused by the processing ripples on the surface of the shaft neck after turning and grinding, 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. Only a sufficiently smooth contact surface can ensure that the vehicle can drive quietly without 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.

In 2023, Yuzhun Precision Machinery will closely cooperate with numerous domestic new energy vehicle companies to jointly promote the transformation of industries related to the new energy vehicle industry chain and accelerate the pace!
