China made gratifying achievements nc technique
In the development and production of CNC system, through the introduction, digestion, absorption, "and" the ninth five-year "key" industrialization, great progress has been made in the nc host matches with arguably already basically changed "dragging its heels" situation, increased significantly, the quality and performance of our price advantage, function of the CNC system with independent copyright industry in the world market, begin with certain competitive power, and gradually increased market share.
1 has with independent intellectual property rights from low to high grade product, has actually breakthrough in China's overseas
Domestic cheap products (economic) has occupied domestic market, has been widely used for reconstruction of old machine and equipment new machine.
Domestic middle-grade product (revised) in the early 1980s batch to enter the market, has been selling 5,000 or more.
High-grade products (senior) is in my limited products abroad. Through the national organization of "five-year", these belong to the embargo and restrictions are we broke the index.
In October 1999 China international exhibition of machine tools already see domestic controllable shaft for 30, 16, 24 or joint axis of the number nine axis CNC system, such as the central axis of the exhibition nc machining center (5 linkage for impeller processing), Beijing mechanical institute and Beijing university of aeronautics and astronautics joint development of CNC system, can JT2010 with a total number of shaft system, control of 50 more composed of machine tool sets machines.
In practical applications, kunming machine company has sales with domestic space nc group with four or five axis CNC system TH5466 type vertical machining center and Taiwan, With domestic high-grade nc national engineering research center of "blue" 7 axis control 5 axis CNC system reform of Japan's five coordinates old processing center, has been in shenyang liming aircraft engine company running more than two years, Domestic 4 "blue sky" linkage of CNC system reform of Japan, makino carries out the old machine factory in tianjin locomotives, one day two class operation for seven years. Use "huazhong nc system of" five linkage of CNC milling machine, which has been used in jinan casting process for impeller.
Domestic advanced type system, and a small number of international thirties. As China's surface directly interpolation (SDI) function. It use software algorithm of complex track directly, in order to realize interpolation, high precision, high speed machining error compensation for processing and intelligent control to lay the foundation.
Belongs to high-grade system of digital profile CNC system, also has already developed and reliable operation.
In addition, all domestic edm wedm machine and some nc edm, almost 100% of the CNC system is domestic.
