CNC machine is our foundation, combat readiness sex industry one, is reflected in Chinas overall strength and industrialization level logo. For years, state of CNC machine industry has been highly, give a various support and devotion. The tenth "five-year" is our country CNC machine important development period, has been a breakthrough and substantial progress.
The "ninth five-year plan period, CNC technology development mode and technical structure changed obviously change, from manufacturing economical, simple type nc machine mainly started large-scale production auv numerically-controlled machine tool, from single sex technology development as began to enter into the systematic technology is given priority to, from the host manufacturing technology development primarily, start modular, functionalized components manufacturing technology is given priority to, to improve the nc machine tools from single function research oriented begin to enter increase of CNC network, intelligence level primarily. The tenth "five-year" end, we CNC machine production "five-year" end growth nearly 100%, the market share increase by 12 percentage points, reliability index increased by 50% ~ 100%. We can say that the ninth five-year plan period, China CNC machine has entered the mature stage of development. The tenth "five-year" CNC technology significant progress is mainly manifested in the following aspects:
- Idustrialization scale greatly improved. The "ninth five-year plan period, our country numerically-controlled machine tool industrialization scale has been relatively substantially rise, formed a dozen auv numerically-controlled machine tools industrialization base and development center, nc machine tools of annual sales volume from" five-year "end 7200 many sets of development to 2000 1.4 million sets, output value of numerical control machine tool from the 8th five-year plan of the rate of 12% to nearly 30 percent in 2000, some key enterprises has reached over 70%, make high-grade numerically-controlled machine tools import greatly reduced, broke through the western in key equipment in the aspects of import restriction.
- Nmerically-controlled machine tools key common technology of a major breakthrough. High speed, high efficiency, high precision technology has greatly developed. "Three-high" has been our and foreign advanced products, one of the main gap between every year because of the three indexes gap and must import of CNC machine accounted for 60% of the total imports. The "ninth five-year plan period, our country of CNC" three-high "technical index had relatively substantially improved. If the coordinates to speed from "five-year" at the end of 10 meters per minute increased to 40 meters per minute, Machining center cutter replacement rate from "five-year" at the end of seven seconds increased to 1.5 ~ 3 seconds, Production line production beat from 3 ~ 5 minutes/piece increased to 0.8 ~.5 minutes/parts.
- Nmerically-controlled machine tools reliability index has increased greatly. Our country of CNC reliability indices (MTBF) has been that influence the market prestige and market competitiveness main problems. The 8th five-year plan period, Chinese machining center MTBF only 200 hours, after five years effort has reached 40 hours, growth rate was 100%. CNC lathe from an average of more than 200 hours increase to an average of 450 hour, Nc system from 5000 hours increased to 10,000 hours above, up to a maximum of 2 million hours.
- Hmebred multi-axis nc system and linkage of CNC machine technology has gradually matured, and enter production application stage. The "ninth five-year plan period, Chinas production of five coordinates linkage and five plane processing machine has many variety, and in the military and aerospace, shipbuilding and other field application, effectively break the overseas for our imports of such equipment limits.
-- key technical breakthroughs made in China CNC technology development with a qualitative leap, produced good social and economic benefits. One is the home-made numerical control machine during 8th five-year plan of the market share only 23%, by 2000 reached 50% (according to quantity plan). The development of CNC machine tools the industry of the domestic market share has reached 50%. 2 it is numerically-controlled machine tool industrialization of technical problem is preliminary already solution, make the industrialization of home-made numerical control machine expanded scale. Three is developed and completed a large number of nc machine tools of new products. Four is our country the machine tool industry since 1999, turn the negative for five consecutive years situation, start to appear positive growth.
