"Now the program has not yet been announced, and is waiting for the final approval of the relevant departments, but has already passed the discussion of the mayor's office." Li Kunsheng revealed that compared with the "2013-2014 program", the highlight of the new program adjustment is mainly "The transfer of vehicles will not be subsidized by the government; the scrapped vehicles will increase by 2,000 yuan." Double Spindle Turning Milling Composite Machine Tool Double spindle butt lathe is an advanced CNC lathe with high in the machine tool industry. Its main feature is that it can achieve multiple types of turning and drilling processing on one machine tool, improving productivity and machining accuracy.

"This year, Beijing's old car elimination target is still more than 200,000 vehicles, the focus is on the national I car and the national II car." On January 17, in the "2015 China Auto Market Development Trend Forum", Beijing Municipal Environmental Protection Agency Motor Vehicle Division Director Li Kunsheng revealed that starting from 2016, Beijing will limit the number of gasoline vehicles under the country I, the main measure is not allowed to enter the six ring.
"This is in line with the policy of completing the elimination of old cars. In addition to the country I, the relevant departments are also studying more than 500,000 National II petrol passenger cars, and gradually adopting measures to reduce pollution after 2016." Li Kunsheng Say.
It is understood that Beijing has already completed the "Reinforcement of Vehicle Emission Reduction to Promote the Retirement of Old Motor Vehicles in the City (2015-2016)". The idea is to promote the combination of economic encouragement and regional prohibition. Old motor vehicles are eliminated and updated to optimize the structure of motor vehicles.
The maximum subsidy for heavy-duty diesel vehicles is nearly 40,000 yuan. In fact, accelerating and increasing the elimination of old cars has become the main means of energy saving and emission reduction in Beijing. By the end of 2014, the number of motor vehicles in Beijing had reached 5.59 million, with annual emissions of 700,000 tons of pollutants. Among the contributions of PM2.5, motor vehicles accounted for 31.1% of local emissions sources in Beijing.
In order to control the rapid growth of the total number of motor vehicles, Beijing has sought to reduce emissions through restrictions on purchases and active promotion of new energy vehicles in recent years, but the effect is not obvious. Dong Yang, executive vice president and secretary general of China Association of Automobile Manufacturers, said in an interview with 21st Century Business Herald that "if we reduce the emission effect of PM2.5 alone, we will promote the economy of 10,000 pure electric vehicles. The cost is not as good as eliminating 100 yellow-label cars."
The current actual case in Beijing is confirming Dong Yang’s point of view. According to Niu Jinming, director of the Beijing New Energy Vehicle Development Promotion Center, in Beijing, a total of 8,050 new energy vehicles were promoted in 2014, with a total promotion of 13,000 vehicles. Although this figure has exceeded the total amount of promotion from 2008 to 2013, compared with the vehicle ownership of nearly 5.6 million vehicles, the contribution of new energy vehicles to reducing PM2.5 is still very small. Its promotion is more about the future.
I. Structure composition
The main structural composition of double spindle docking lathe includes machine body, CNC system, tool holder, toolholder, spindle, collet, turning center, tool, etc. Among them, the machine tool body is the foundation of the whole lathe, mainly responsible for supporting and fixing each component to ensure the stability of the machine tool. The CNC control system is the intelligent brain of the lathe, which centrally controls and manages the operation and machining process of the lathe. The tool holder and tool shank are used to hold and fix the tool and cut the workpiece. The spindle and collet are the core parts of the lathe, which are responsible for driving the workpiece and cutting tools, etc. for machining.
II. Working Principle
The working principle of double spindle docking lathe is similar to that of ordinary lathe, but it has double spindle structure. Its spindles can run together or work independently to process two workpieces at the same time, thus realizing multiple tasks on one machine tool. This lathe adopts advanced CNC technology, which can freely adjust the processing parameters as needed and highly automate its working process.
III. Application Scenario
The twin-spindle docking lathe is widely used in the processing of various materials such as metals and non-metals in the industrial field. Its main application scenarios include:
(1) Aerospace field: manufacturing various aerospace engines, accessories and parts.
(2)Automobile manufacturing industry: used to produce various cars, trucks and motor vehicle parts.
(3) Medical devices: for the production of various medical devices and medical equipment.
(4) Electronics field: for the production of a variety of electronic product housings and parts.
(5) Machinery field: for the production of various machinery, industrial equipment and parts.
In a word, double spindle butt lathe is a kind of advanced CNC lathe that is standardized, modularized and equipped with advanced mechanical, electrical, hydraulic, pneumatic and computer control technologies. Its high efficiency, high precision and high automation make it have great advantages in terms of return on investment, production efficiency and product quality.
