Rapid development of construction machinery drives strong demand for machine tool industry

In the past five years (2006-2010), China's construction machinery industry completed a self-improvement and transformation. In the past five years, the average increase of the market has maintained an average speed of more than 20%, and the industrial scale has grown rapidly. In 2010, China's construction machinery industry made great strides. The total industrial output value was 436.7 billion yuan, an increase of 38% year-on-year.

The 12th Five-Year Plan for the newly released construction machinery industry shows that by 2015, the projected sales volume of China's construction machinery industry will reach 900 billion yuan, with an average annual growth rate of about 17%, of which the export value will exceed 26 billion US dollars. The growth rate reached about 25%; in 2015, the sales revenue and export volume of the entire industry more than doubled from 2010.

1. The booming development of construction machinery drives the strong demand in the machine tool market to thrive in the construction machinery industry and promotes the development of the machine tool industry. As one of the important users of the machine tool industry, the construction machinery industry needs more and more vertical and horizontal machining centers (processing shells, transmissions), CNC lathes, CNC grinding machines, gear processing machines, and CNC special machines. Need a lot of forging equipment such as large CNC shears, CNC bending machine, CNC cutting machine, automatic loading and unloading of various presses. In addition, welding robots, robots, paints, and surface treatments are also required.

Regarding the growth targets set out in the “12th Five-Year Plan” of the construction machinery industry, some experts believe that the future growth rate will be faster than the average growth rate of 27.5% in the past five years and the average growth rate of 23.8% in the past 10 years. Slow development is a medium-to-long term trend. The capacity of construction machinery market is far from saturated, and the sales revenue of the industry will continue to increase in the next five years. In terms of exports, most of them are exported to emerging economies such as India, Brazil, and Russia, as well as the Middle East and China’s economic development. In countries and regions with similar stages, China Construction Machinery will gain a huge export market by virtue of its cost-effective advantage.

From the perspective of the subdivision industry, market demand for machinery such as cranes, bulldozers, forklifts, excavators, etc. will continue to grow, and maintain a longer growth cycle. All these have brought the requirements and demands of the construction machinery industry to a new height.

2. Increased R&D of machine tool companies has continuously introduced applicable products Faced with such a huge market for construction machinery, each machine tool company has launched the latest applicable machine tools.

Chongqing Machine Tool Group YT4232CNC4 four-axis CNC shaving machine The YT4232CNC4 four-axis CNC shaving machine developed by Chongqing Machine Tool Group is an efficient gear finishing machine. Through the preparation of the part processing program, the machine can realize the razor stepless speed change, the tool holder automatic corner turning and loose locking, and the tool micro-return machining. At the same time, the machine tool is equipped with a regular, quantitative automatic lubrication device, which can automatically lubricate the guide rail, screw and other components. The main electrical, hydraulic components, and key bearings of this machine are all imported products to ensure the reliability of the machine's normal operation. The machine tool also has an automatic chip removal device, which can be equipped with disk teeth, shaft teeth, and feeding devices. When machining slender shaft teeth with floating auxiliary support.

Qinchuan Machine Tool Group: The VTM260 Gantry Milling Compound Machining Center VTM260 Gantry Type Turning and Milling Compound Machining Center is a new generation of turning and milling compound processing equipment independently developed by Qinchuan Machine Tool Group. The machine tools, boring, milling, grinding and other different types of work are highly integrated and highly efficient. They can process all kinds of metal parts and their alloy parts in one setup, including turning planes, inner and outer cylindrical surfaces, and steps. , A variety of rotating surfaces, as well as milling plane, boring, drilling, tapping, thread and so on. It adopts Siemens 840D control system, the position detection adopts the full-closed-loop control of HEIDENHAIN grating, and can complete the two-axis to four-axis linkage control. After the accessory swing head is installed, it can expand the number of numerical control axes, so that the machine tool has seven-axis and five linkage functions. Complete high-efficiency, high-quality machining of various complex plane and curved parts.

Nanjing No.2 Gear Machine Tool Co., Ltd.: YX3132CNC High-efficiency Gear Hobbing Machine NGC Machine Tool Co., Ltd. developed a YX3132CNC type CNC high-efficiency hobbing machine, which is a five-axis CNC high-efficiency hobbing machine and realizes five-axis four linkage control. The X-axis and Z-axis of this machine are directly controlled by independent AC servo motors, which have the characteristics of short drive chain, good rigidity and high precision. Its Y-axis is controlled by AC servo motor, which makes the tool boring tool more accurate and can realize the need for tooth function. The main movement uses an AC spindle motor mounted directly on the tool holder and can withstand large cutting forces. A multi-headed hob can be used for large-feed hobbing. The machine tool adopts the way of fixed table and column movement to realize radial feed motion, which improves the processing rigidity.

Shenyang Machine Tool Group: ETC Series Horizontal Turning Centers Shenyang Machine Tool Group has launched a series of products for the construction machinery industry. Among them, the ETC series of horizontal CNC lathes are high-performance products developed in response to market demand and can complete various axes. Efficient machining of parts and discs. The machine tool adopts a flat bed body inclined bed saddle structure to reduce the installation height of the spindle tail table and the bed saddle, greatly improving the rigidity of the whole machine; the linear guide rail equipped improves the precision of parts processing and effectively reduces the crawling phenomenon of moving parts; The motor improves the dynamic performance of the machine tool and improves the machining accuracy of the part.
