Yang Xuetong of standing deputy secretary-general expresses Chinese mechanical Joint Industry Conference, through introducing a technology, digest attract and science and technology tackles key problem, the crucial technology that affects development of estate of our country numerical control obtained major breakthrough. This is the information that the pattern of industry of international machine tool that the reporter held at Chongqing recently obtains on new technology exhibition. According to introducing, in respect of numerical control system, solved the preliminary changeover of structural sex above all. "85 " evening, our country develops without specific technology advocate frame, use special integrated circuit namely, still be platform construction of the foundation with PC. "95 " during, the country develops clearly to be the numerical control system of platform with PC about the branch, through " 95 " tackle key problem, now on frame preliminary already finish. Next, increased the dependability quota of numerical control system, MTBF achieves 20 thousand hours by 5000 hours, this one index makes system of homebred numerical control achieves international advanced level, solved domestic user basically to produce the high level demand of the enterprise. In the meantime, solved the technical difficult problem of much coordinate linkage. Linkage achieved the 3 coordinate from in the past to be able to amount to 8 coordinate linkage at most, broke abroad the technology to our country " limitation " . In the meantime, system of our country homebred numerical control already had batch productivity, market brand also is being established stage by stage. In respect of numerical control machine tool, solved the cognizance method problem of dependability index above all. "85 " the MTBF of machine tool of numerical control of evening our country has 2 OO hour only, through effort of these a few years, already achieved 400 hours now, growth range amounts to 100 ％ . The 2nd, rotate speed of machining center main shaft by minutely 4000 convey 10 thousand turn, because index of this one crucial technology is low,solved, create the problem that machine tool of many abroad numerical control imports. Current, the crucial product of this one technology also already small lot production, be like inside main shaft of the report that fit pattern. The 3rd, coordinate feed speed by " 85 " of evening minutely increase 40 meters 15 meters, reached international level. The 4th, machining center changes knife rate by " 85 " 8 second of 5 ～ reduces evening １ . 3 second of 5 ～ , also approached world advanced level. Yang Xuetong says, system of high-grade to be being imported to our country numerical control executes foreign developed country contraband policy, the country regards Chongzhongzhi as to support again the development of CNC system all the time, already developed the CNC system that has Chinese copyright now, mastered a few crucial technologies that abroad blocks to our country all the time, product of form a complete set of machine tool of major numerical control already can be produced, ego form a complete set leads ％ of more than 6 O. The product of machine tool of homebred numerical control of new development reached the metaphase level of 80 time for the most part, the part achieves international 90 age level, for national emphasis construction provided the numerical control machine tool of a batch of Gao Shuiping. As we have learned, manufacturer of production of machine tool of current and main numerical control shares our country many 100, among them can the enterprise of machine tool of batch birth numerical control 42; Total production value of numerical control property achieved 85.3 billion yuan 2003, entire industry profit achieves 4.2 billion yuan.
