The CNC rate of products jumped from 21.3% in 2001 to 70% in 2007; CNC machine tools were exported in batches, of which 4 were exported to South Korea in 2007 alone (each worth more than US $1 million); The large-scale CNC milling and boring machine with five axis linkage at the international advanced level has been mass produced; Kunming Machine Tool Co., Ltd. of Shenyang Machinery Group, whose CNC machine tool products are widely used in many fields such as aerospace, aviation, engineering machinery and so on, has become an important production base of large-scale precision CNC machine tools in China. "Kunji brand" was rated as "the most competitive brand in China" by the Ministry of Commerce

develop high value-added products from a high starting point and occupy market share advantages

Kunming Machine, known as a "Pearl" of China's machine tool industry, has successively developed more than 140 "China's first machine", filling a series of gaps in the country. With the sustained and rapid growth of China's economy, the demand for the development of transportation, raw materials, energy industry and aerospace industry, and the transfer of world manufacturing industry to China, the market has a blowout demand for large machinery and equipment. It is against this background that Kunming Machinery Co., Ltd. has started the research and development of large-scale CNC Floor milling and boring machines since the end of the last century. After more than four years of research, it has successively completed the research and application of more than ten key technologies, such as high-speed spindle structure, high positioning accuracy of large (heavy) moving column movement, automatic tool change technology, multi axis machining and high-speed machining technology. At the end of 2001, it developed and produced a large-scale CNC Floor milling and boring machine with international level represented by tk6916, whose machining accuracy has reached the international advanced level. So far, the cumulative orders of this series of products have exceeded 270 sets, with a value of more than 1.35 billion yuan. It has occupied more than 60% of the market share of large-scale CNC Floor milling and boring machines in China, and has become a new economic growth point of the company

transform traditional products with high and new technology to realize product upgrading

Kun machine has formed a series of horizontal boring and coordinate boring products of various specifications since the 1950s, which is known as the "boring machine family". Since the beginning of the 21st century, the company has been committed to transforming traditional products with high-tech and accelerating the pace of product upgrading. The company has developed the first th61140 horizontal boring machining center in China. This product not only maintains the advantages of good rigidity, large bearing capacity and large spindle torque of the horizontal boring machine, but also is equipped with advanced numerical control system and tool library. The system is equipped with CNC, PC diagnostic display, three-dimensional graphic display and other functions, and realizes the five axis control of X, y, Z, W, B, and any four axis linkage. Its positioning accuracy and repeated positioning accuracy have reached the international leading level. At the 10th European International Machine Tool Exhibition, as the high-end CNC machine tool product with the largest specification and the highest precision of the Chinese delegation, this product was highly praised and concerned by all parties. In 2007, the company completed the upgrading of the structure and performance of the precision horizontal machining center developed in the mid-1980s, and developed new and large-scale precision machining center products represented by th65125. The successful development of the new horizontal machining center has achieved the purpose of improving product performance, rapid transformation and mass production. The fastest assembly cycle is only 35 days. After years of efforts, Kunji has developed a number of high-tech CNC machine tools integrating modern machine, electricity, light, liquid, gas and information technology. The mass production of these CNC machine tools not only made the CNC rate of Kunming Machine Tools jump from 21.3% in 2001 to 70% in 2007, but also made the economic benefits of enterprises increase significantly. The company's sales revenue jumped from 102 million yuan in 2001 to 840 million yuan in the first three quarters of 2007, which made me blush and heartbeat, an increase of 8.4 times. The net profit jumped from 2.05 million yuan in 2001 to 172 million yuan in the first three quarters of 2007, an increase of more than 84 times. The company's single product price increased from 472000 yuan to 974000 yuan, The ranking of comprehensive economic benefits jumped from 97th (2003) of the 100 key linked enterprises in the national machinery industry to 18th (January September 2007), and the ranking rose by 79

overcome the difficulties of five axis linkage high-end machine tools and leap to the commanding height of machine tool industry

multi axis control and five axis linkage CNC machine tools are contemporary high-end CNC machine tools products. They are the key equipment urgently needed by military industry, shipbuilding, aerospace and other industries, and have been listed in the prohibition list of China by western developed countries for a long time. In August, 2004, Kunji started to tackle this high-end technology by taking the opportunity of a TK6920 five axis linkage large-scale combined CNC Floor milling and boring machine developed and produced by a wholly owned Austrian enterprise in China. After one year and two months of research by engineering and technical personnel, they have successively broken through a series of technical difficulties, such as spindle system integration technology, five axis linkage processing technology, new technology of spindle and accessory head tool internal cooling structure, in addition to a series of problems caused by high stiffness ram type components. In December 2005, they successfully developed a five axis linkage large-scale CNC combined milling and boring machine

this machine tool realizes 14 axis control and five axis linkage, and can process curves and surfaces with arbitrary complex shapes. Its large-scale moving column long stroke moving positioning accuracy and heavy-duty rotary table continuous indexing positioning accuracy have reached the world advanced level. The self-developed automatic head changing structure of the ram spindle is simple and reliable. It can align, grasp, grasp and rotate the universal milling head weighing up to 1.6 tons placed on the rack during movement, and the machining accuracy fully meets the requirements. After this five axis CNC combined milling and boring machine with various advanced structures and high-end technologies was put into the user's production line, it operated for 8 months and earned back 17million yuan of purchase cost for users. At present, Kunming Machinery Co., Ltd. has been able to mass produce five axis linkage mainframe, three of which have been successfully operated on the user's production line, and another three are under construction

now, Kunming Machinery Co., Ltd. is working hard to provide users with flexible production lines instead of five axis linkage machine tools in batches, so as to realize full automation and high intelligence of production and manufacturing, and climb a new peak of the world machine tool industry
