Milling is a cutting method that takes milling cutter rotation as main movement, workpiece or milling cutter as feed motion.
1. plane milling
In mass production, the machining of box parts is mainly using cemented carbide welded circular surface and cemented carbide machine clamped Indexable Surface for plane milling.
The main machines used in the plane milling of automobile case shell parts are vertical and horizontal lifting table milling machine, vertical single-axis and double-axis rotary table plane milling machine, combined milling machine and special milling machine.
2. milling of crankshaft journal
At present, CNC crankshaft milling machine is widely used in the rough machining of crankshaft journal and connecting rod journal using carbide milling cutter.
Milling has the characteristics of high quality and high productivity.

Chongqing Feilong Jiangli latest information. Juniper Research, a market research firm, predicts that by 2030, more than 62 million vehicles will have V2V communication capabilities, more than 1.1 million more than in 2019. V2V solution can achieve low delay communication between vehicles, especially to improve driver safety.
The new study by Juniper Research, titled Consumer Networked Automobile: Remote Information Technology, Vehicle Application & Networked Automobile Business 2018-2023, shows that the 5G network launched in 2019 will be the key driving factor behind the expansion of V2V communication technology. The study predicts that OEM will prefer to use 5G technology for V2V communications rather than other technologies because 5G technology has lower latency and higher radio frequency range.
Juniper Research found that the development of 5G technology will promote the commercial deployment and interoperability of 5G technology, and predicted that by 2030, the United States will become the main market for deploying V2V technology, and 60% of new cars sold in the United States will have V2V function. The technology could reduce the annual death toll in the United States by more than 9,300 people, accounting for 25% of motor vehicle deaths.
In addition, the study also predicts that manufacturers of automotive original equipment will explore new strategies such as on-board content subscription to generate revenue in addition to automotive sales. The study predicts that applications directly integrated into vehicles will generate more than $2.2 billion in revenue by 2030.
Juniper Research suggests that in addition to using 5G networks, OEMs must also open up their on-board ecosystems to third parties to accelerate the development of emerging and future automotive content revenue streams.

According to foreign media reports, the German car companies represented by BMW, Daimler and Volkswagen have been working hard to develop electric vehicles and self driving cars, but the pressure is still relatively large. In North America, China and Europe, the world's largest automobile market, all automobile manufacturers have joined a new wave of competition. However, the German automobile industry has obvious disadvantages.
Automobile electronics is the trend of the times, and digitalization is also the future direction of automobile development, including automatic driving. This means that in addition to the traditional automobile manufacturers, technology companies will continue to enter the competition in the future automobile market.
From another point of view, for German auto companies, the opening of the era of electric vehicles is also more difficult. First, from the profit point of view, the profit of electric vehicles in the early stage of development is obviously less than that of traditional energy vehicles. For example, Toyota and Volkswagen, the traditional car giants, have annual operating profits ranging from 15 billion to 20 billion euros, while high-tech companies such as Apple make about three times their annual profits.
Pressure bears the power, because Feilong Jiangli's parent company, Xipu, is supporting German brands such as Volkswagen and Daimler, we are full of expectations and confidence for the development of German brand automobile enterprises.

Chang'an automobile sales fell 20.4% in November, and SUV models declined severely.
As a supplier who has been cooperating with Chang'an, Chang'an's sales also affect the sales performance of Feilong Jiangli in Chongqing. We look forward to the recovery of Chang'an's sales, and promise to develop high-quality new products with Chang'an to provide better service to customers.
Chang'an Automobile released the latest sales data: in November, Chang'an Automobile sold 118,902 Chinese brand cars, down 20.4% from last year. Among them, three SUVs, CS35 series, CS55 and CS75 have declined seriously.
Chang'an CS75 sold 12,036 vehicles in November this year, down 54.5% from November last year. From January to November this year, it sold 132,680 vehicles, down 39.2% from last year. At present, the preferential range of Chang'an CS75 is also very large. The preferential price of bare-car has changed from 0.6 million yuan to 15,000 yuan, and it enjoys 24-period interest-free loan policy.
Chang'an just launched a new model CS35 PLUS at the end of October this year. Now it is sold together with the old classic CS35. In November this year, 12,751 CS35 series two models were sold. Compared with November last year, the total sales of the two models were not as good as last year's single classic CS35, a 27.4% decline.
Chang'an CS55 has a relatively stable performance. It sold 15,777 vehicles in November this year, basically the same as last November, but fell by 7.2% compared with last month. Chang'an CS55 was replaced in August this year, but the results are not obvious. Sales this month are still lower than rivals Geely Boyue (19,575) and Harvard H6 (54,226).
