Precision Machining Steel accounts for a very high proportion in the CNC machining steel industry, whether it is CNC turning or CNC milling. CNC machining of metal parts requires selecting appropriate tools, setting reasonable parameters and programming reasonable tool paths according to the material and structure of the parts in order to produce good products. This has very high requirements on the technology and experience of the production engineer. Whether a product can meet the requirements depends largely on the production engineer. The same equipment and the same tool may produce two completely different products under the operation of different engineers.
SCZY offer the Precision Machining Service,our production engineers have more than 10 years of experience in the precision machining steel parts, and can easily deal with workpieces of various materials and structures, and can ensure the pass rate of the workpiece.

From the second half of 2009, the national 4 trillion yuan investment has begun to show its pulling effect on the economy. In 2010, many major construction projects began to be implemented, which led to the rapid growth of sales of engineering dump trucks. In addition, the continued recovery of the macro-economy has made the logistics market work hard, and the growth of road freight has driven the rapid growth of road vehicles. In the economy and automotive industry, the growth of the medium and heavy truck industry has become the main theme, but there are also many uncertainties, such as real estate control policies, the implementation of new emission standards.
In the commercial vehicle sector, driven by the recovery of the logistics market, the sales of highway heavy trucks and semitrailer tractors recovered rapidly, and the overall recovery of the heavy truck industry showed signs of improvement. The reason is that under the premise of continuous improvement in the macroeconomic environment and low levels of vehicle ownership in China, auto consumption will still exhibit echelon shifts. The space for auto sales in the third and fourth tier cities will remain relatively large. At the same time, the Yangtze River Delta and the Pearl River delta and other developed coastal regions Demand is still recovering.
With the country’s investment in railway construction and the continuous investment in highway construction investment, the continuous improvement of transportation infrastructure has been promoted. The construction of transportation infrastructure has not only stimulated the demand for engineering vehicles, but also provided a good transportation environment for road transport vehicles. The demand for the heavy truck market is also increasing. Heavy trucks, Shaanxi Auto, and Dongfeng dump trucks also saw a significant increase in sales. According to the usual practice, September is the peak season for heavy truck sales. If the first half of the year is driven by engineering construction, the market in the second half of the year will rely more on the logistics industry to drive the sales of tractors. Agricultural products, coal, etc., are the key transport goods at this stage.
In 2010, the National Plan for Western Development initiated 23 key projects. The project covers railways, highways, and airport construction as well as power, water conservancy, and coal mines. The total investment is 682.2 billion yuan. In the new round of western development, as the country’s investment in infrastructure construction increases, the western development of coal, natural gas and other mineral resources will have great opportunities for the domestic heavy truck companies in the west. The Steyr series of heavy truck products will have a very large market share. Steyr's heavy-duty truck products are highly cross-country, highly load-bearing, and high-passenger. At present, there are no other products that can be replaced in the domestic heavy-duty truck industry, especially engineering vehicles. From this point of view, there will be more opportunities for heavy truck companies in the central and western regions, including Shaanxi Automobile, SAIC Iveco Hongyan, Grand Canal Heavy Truck, Bei Ben Heavy Truck, etc. Shaanxi Automobile in particular will take advantage of favorable conditions such as favorable weather conditions. Of course, heavy trucks are generally national sales strategies. Other heavy truck companies such as CNHTC, Dongfeng Heavy Duty Truck, Foton Heavy and other famous brands, will also occupy a certain share in the new round of development of the western region.
Another concern is that the demand for special dump trucks is constantly increasing. In recent years, in the process of national economic development, a large number of heavy-duty trucks are required to meet the needs of all walks of life in the country in terms of energy extraction, infrastructure construction, logistics and transportation, and army building. Especially in terms of mining and large-scale construction projects, it meets the characteristics of greater bearing capacity, greater payload quality, and more economical efficiency. The special dump truck has the advantages of strong horsepower, large carrying capacity, and durability. The tonnage of tonnage is two to three times that of ordinary conventional heavy trucks, and a conventional self dumping of two to three vehicles of a special dump truck. Under the background of fuel shortage, special dumping is definitely the development trend of mines and engineering transportation in the future. With the development of the economy, the continuous improvement of energy exploration and development, the start of construction of national-level large-scale projects, and special dump trucks, that is non-road dumping, will certainly be the new trend of heavy truck development.
With the deepening of the new round of western development and the improvement of road and other transportation facilities, the exchange of materials between the east and the west will become increasingly frequent, which will promote the development of the logistics and transportation industry. The development of the logistics and transportation industry has also provided considerable opportunities for tractors, tractor-trailers and trucks in China. The recent freight market lacks bright spots and relatively few sources of goods. Recently, due to the impact of typhoon, a large-scale national precipitation in the past period has affected roads and traffic, and cargo transportation has also been adversely affected. After the weather conditions have stabilized, the market will be better, and before the onset of winter each year, the demand for coal transportation is still relatively large, and there will be some demand for tractors. The peak sales of dump trucks are expected to wait until next year.
After the introduction of a new round of regulation and control policies at the end of September, the volume of transactions in major cities across the country declined significantly, and the market watching atmosphere once again increased. China’s real estate policy has gradually shifted from early support to curbing speculation, thus curbing excessively rapid price increases, and has adopted land, finance, and taxation measures. The introduction of real estate control policies will more or less give a certain impact on engineering trucks.
According to the requirements of the "Limits and Measurement Methods for Exhaust Pollutants for Compression Ignition, Gaseous Fuel Ignited Engines and Vehicles for Vehicles", all heavy-duty vehicles shall be implemented on January 1, 2010, except heavy-duty gasoline vehicles. The IV emission standards were delayed due to the impact of supporting facilities. However, in any case, the protection of the environment has received more and more attention. It is imperative to reduce emission standards.
It is reported that compared with the State III, the “National IV Standard†requires that the emission of light-duty bicycles be reduced by about 50% on the basis of the former, that of heavy-duty vehicles by about 30%, and that of particulate matter by more than 80%. For this reason, the electronically controlled fuel injection system of the engine needs to be re-matched, and the catalytic converter formula is re-calibrated, and precious metal elements are added, so that the control accuracy of the electronically controlled fuel injection is higher. The shortage of technology and rising costs will impose a certain restrictive effect on enterprises. In addition, the oil products that meet the national IV emission standards have not yet been fully popularized, and their prices will also be adjusted upwards. This will certainly have a certain influence on the purchasing enthusiasm of car consumers.
