More than eight years into the 21st century, China's national economy to maintain a healthy, sustained and rapid development momentum, to create a good environment for the rapid development of China's heavy-duty machine tool industry. Operating in the market, the heavy machine tool enterprises industrial output value, sales revenue, gross profit, following Order Quantity historic growth of more than 40% higher than the average growth rate of the country's machine tool industry. CNC machine tool output value accounted for more than 85% of GDP. Visible heavy machine tool demand situation and market capacity for the organization of production and product development of China's heavy machine tool manufacturing industry provides a very good environment for the development of the upside.
1. heavy machine tools concept with major manufacturers
According to the provisions of the former State Ministry of Machinery Industry Bureau of the machine tool, the machine's own weight in the range of 10-30t machine is a large-scale machine tools; 30-100t is a heavy-duty machine tools, more than 100t is a heavy machine tools. Now no authoritative department to give a new definition.
Fifteen countries in the construction of 156 key projects, started to build the country's first professional manufacturer specializing in the production of heavy machine tools Wuhan Heavy Machine Tool Factory (heavy weapons). Takeshige products include more than 30t lathes, milling machines, boring machines, grinding machines and other products. Takeshige produce China's first heavy-duty 6.3m vertical lathes, Jinan Second Machine Tool double Deyang produce a working width of 6.3m heavy planer. Able to provide heavy-duty machine tool manufacturers in the planned economy era: Wuhan Heavy Machine Tool Plant, Qiqihar First Machine Tool Plant, Qiqihar Second Machine Tool Plant, Jinan Second Machine Tool Plant, Beijing First Machine Tool, Heavy Machine Tool Plant in Qinghai, Shanghai Heavy Machine Tool Plant, Xianfeng Machine Tool Factory and a number of national enterprises. These enterprises are responsible for national key construction projects need the key heavy processing equipment manufacturing tasks.
After the reform and opening up, China's national economy has entered a stage of rapid development, especially into the more than eight years since the twenty-first century, unprecedented strategic opportunities, strong market demand for the product development of heavy machine tools, to promote China's heavy-duty machine tool industry the production and sales situation. Now our own development and manufacturing of heavy machine tools and heavy machine tool products, has been basically meet the needs of the national key projects, and many times to create the world's most ultimate specifications, such as China has produced a super-heavy-duty CNC vertical milling machining diameter 25m floor type boring and milling machine, lathes, boring bar diameter Φ320mm processing width of 5m or more CNC gantry milling, turning diameter over Φ5000mm CNC heavy duty horizontal lathe, and so a number of independent intellectual property rights and the technological level is close to the world advanced level the heavy-duty machine tool products.
Since entering the market economy, the tradition was broken, and the division of labor is canceled, the production of heavy-duty machine tool manufacturers in China has been far more than the original professional factory areas of heavy machine tools. The past eight years, many of the original production of heavy machine tool manufacturers have expanded reproduction, started to develop a heavy machine tools, and bigger and bigger. The same time, some of the original production of a single species of heavy machine tools, also invested heavily in technological transformation started to enter the vertical lathe, horizontal lathe, Boring and Milling, gantry milling machine and integrated product development and production. The market demand nurture product development and technical level of China's heavy machine tools to improve heavy machine tool manufacturers also makes our team continues to expand. In the country's rapid economic development environment, the user needs to cultivate the market, the level of China's heavy machine tools will continue to be developed to a higher level, heavy machine tools manufacturing team will continue to update and grow.
2. The main products of the heavy machine tool manufacturing industry in China
Nurtured in the market, the level of technology and manufacturing capabilities of our heavy-duty machine tool products. Some have reached or close to the world advanced level, technical level of some products have entered the most advanced in the world, such as vertical milling lathe processing, China has developed and manufactured the the world specifications largest processing diameter 25m CNC mill-turn machining centers, currently being developed The diameter of up to 29m super heavy-duty five-axis vertical milling lathe.
Heavy-duty CNC vertical lathe products to meet domestic needs and export some products, has developed a machining diameter 5m; CNC heavy duty horizontal lathe, machining length of 20m, carrying the weight of 500t super-heavy-duty CNC sleeper, similar products in the carrying amount of the world's most present, China can already production and processing of the maximum diameter of 6.4m CNC horizontal lathe. Floor type CNC milling and boring products, has developed a boring bar diameter for the Φ320mm the world's largest specification heavy duty NC Boring and Milling. Five-axis milling and boring series development and the formation of the bulk product.
Gantry boring and milling machine is the fastest-growing in China, the largest manufacturer of heavy-duty machine tools. In order to meet the need of different types of users, provides fixed gantry, Gantry Moving Ssangyong door mobile, fixed beams, beam mobile gantry beams mobile viaduct type multi-species multi-standard products. China has the specifications into mass production processing over 5m width, heavy duty CNC machining length of 20m or more gantry boring and milling machine.
Currently, manufacturers are developing production and processing widths up to 9.6m working height of 8m machining length of 58m and with a the circular rotary table gantry CNC milling mobile. Gantry milling machine series, high-speed machining, molding, five-axis machining technology has been widely used. CNC Roll Grinder China already developed grinding diameter Φ2500mm, and the grinding length 15000mm, CNC heavy duty roll grinding machine bearing 250t.
China can manufacture the the machining diameter Φ12500mm heavy gear cutting machines. The heavy-duty crankshaft machining, deep hole machining, rail vehicles, rail grinding machine CNC special machine has a series of products to meet the processing needs of various user industries.
