China's auto industry will usher in the next gold for 10 years

On September 17, the first Global Automotive Forum successfully concluded in Chengdu. Wang Xia, head of the forum’s organizing committee and chairman of the Automotive Industry Committee of the China Council for the Promotion of International Trade, believes that after the financial crisis, the global economic center of gravity has shifted from the “Washington consensus” economic system led by the United States to Asia represented by China. As the country shifts, a genuine "Beijing Consensus" is forming. And for the Chinese auto industry, it will usher in the next golden decade. The independent brands will complete the process from "Made in China" to "Created in China."

Chinese cars are going from big to strong

"China's auto industry has completed the process of growing from small to large, and is gradually achieving a leap from weak to strong." Wang Xia said that at present, China's auto market has begun to transition from emerging markets to mature markets, not only the rapid development of the market, auto consumption. The demand changes quickly. Under the background of the global economic crisis, the global automobile industry will transfer to China and some emerging economies. For the Chinese auto industry, it brings a very rare historical opportunity.

“Under such a backdrop, China’s vehicle ownership has also grown at an alarming rate and will continue to expand. China’s autos have undoubtedly become a bright star in the world’s auto industry.” Wang Xia believes that Chinese auto companies need to do most at present. , is to firmly develop independent innovation, but also to do a good job in joint ventures and cooperation; accelerate the research and development of energy saving and environmental protection technologies and new energy vehicles; further promote the merger and reorganization of enterprises, expand the scale of the company; at the same time note the importance of the company's product quality , Branding efforts. Only in this way can China transform from a "car big country" to a "car powerhouse."

Domestic brands are inevitable in the world

The process of global economic integration is getting faster and faster. The development of China's auto industry will inevitably take the path of internationalization. But how?

“Can not simply repeat the road of the Japanese and South Korean automotive industry to rely on the development of the American market. We should start from the emerging markets and developing country markets.” Wang Xia reminded Chinese auto companies that in international trade, with the degree of internationalization of Chinese companies To increase, there will be more and more trade disputes or trade frictions. We hope that companies can make full preparations.

China is undergoing mergers and acquisitions, the general trend of the alliance, Geely Group recently acquired the famous brand Volvo is a landmark event. Wang Xia believes that the future of China will have more such things happen, and this is a trend that the world is experiencing. In addition to mergers and acquisitions between manufacturers, the integration between suppliers is also a future attempt, because the first-tier, second-tier, and third-tier suppliers have differences in each level, but overall, they still have mutual Linked, it can be integrated through strategic cooperation.

There is no competition without excess capacity

As we all know, China’s auto production was 15 million vehicles last year, but sales were only over 13 million vehicles throughout the year, and over 1 million excess capacity was generated. If the Chinese auto industry is bound to take the path of internationalization, will the issue of overcapacity be aggravated?

"This is not just a problem in China, but the world is facing industrial excess capacity." Wang Xia said that this is a challenge, but if there is no excess capacity, then there is no competition. "For automobile manufacturers, as a corporate strategy, it is a normal choice for capacity planning.

It is normal to have a certain overcapacity. This is a market situation and it is impossible to control it. “Wang Xia believes that the automobile industry is a capital and technology-intensive industry. If there is no scale, the cost will not fall. It is normal for companies to increase production capacity in order to reduce costs, and there is no need to expand this topic.” After all, the auto industry It is a competitive industry that ultimately wins through competition. Automobile manufacturers want to win the competition, and efforts to reduce costs will be one of the effective means."

Turning Parts:

Turning the workpiece in a lathe using the method of cutting tool rotation processing workpiece. Turning processing cutting is mainly composed of workpiece and not provide tools. Turning is the most basic, the most common method of cutting, occupies a very important position in the production. Turning for processing rotary surface, a large part of workpiece with rotating surface turning method of processing can be used, such as the external cylindrical surface, inside and outside the cone face, face, groove, screw and rotary forming surface, the tool is mainly used tools. Turning precision is generally it11-it7, some can reach IT6, surface roughness Ra 12.5-08um. can be achieved by Turning Parts, we call turning parts, there are many kinds of turning parts, most famous is via hard turning to maintain the thermal stability of the parts.

 

Category:

Based on different facilities(CNC facility) to do the turning process,CNC turning parts included Lathing Parts,milling parts,Grinding Parts;

Basically,we can realise it on different raw material,like copper alloy,steel,and aluminium alloy.

 

 

Concerned Factors:

(1) The biggest problem is to use or without cooling liquid. For interrupted cutting parts such as gears, the best use of "dry turning", otherwise the thermal shock feed and withdrawal knife is likely to cause the blade to rupture. As for the continuous cutting knife head, high temperature produced in dry turning process to toughening (softening) the pre cutting area, thereby reducing the hardness of the material to make it easy to cut. This phenomenon shows that the stem cutting speed increase is good. At the same time, no coolant cutting method has obvious cost advantages. (2) Layer whitening whitening scald layer (heat affected zone) "may be a dislike to appear in hard turning and grinding operation, namely in the material surface to form a layer of invisible to the naked eye is very thin (typically 1 m) crust. The formation of albino layer in the hard turning process, usually because of blade Passivation causes too much heat to the inner parts. Often whitening on bearing steel form, and it is very harmful to the bearing ring like need to withstand high contact pressure parts, with the passage of time, the albino layer may stripped and lead to bearing failure.

(3) Machine:stiffness determines precision hard turning. Nearly 15 ~ 20 years of manufacturing machines in the almost all have good rigidity, enough to withstand hard turning. In many cases, the overall condition of the machine is largely over the use of life is more important, the general maintenance The opening of the bed can also be used for hard turning. In order to increase the rigidity and damping characteristics for hard turning machine, hatey characteristics of many advanced machine tool for the machining center, including polymer composites reinforced with a spring clip (the spindle support near the workpiece) is directly matched with the spindle and hydrostatic guideway system. The maximum rigidity means a tool to reduce vacant, and extending parts out, and cancel the adjustable gap plate and gasket, its goal is to keep all parts as close as possible to the turret.

(4) Process:because of the heat generated by hard turning most chips away, before and after the processing of chip inspection You can find the whole process is coordinated. Continuous cutting, the chip should be blazing orange, and like a ribbon like flowing out. If the chip after cooling by hand pressure fracture, shows that cutting heat is normal.

(5) Blade:cubic boron nitride (CBN) inserts the price is expensive, but the most suitable for the hard cutting blade CBN.Cbn blade can keep unchanged in the positioning of intermittent cutting process, to provide a safe tool wear rate in continuous cutting process. When using the hard turning process reasonable, except in the control of CBN blade diameter tolerance is not better than grinding, other properties are second to none.
