1. China International Machine Tool Exhibition (CIMT) is hosted by cmtba. Since 1989, it has been held every two years (every single year) and has been successfully held for eight times. The exhibition scale of CIMT has always ranked first in all kinds of international professional industrial exhibitions in China, and it has become an important place for international advanced manufacturing technology exchange and trade, and a driving force for China's machinery manufacturing technology progress and industrial development. The new China International Machine Tool Exhibition (CIMT20 12) will hit a new high in previous exhibitions. CIMT exhibition is the most active exhibition in the international machine tool exhibition, and it is a high-grade exhibition with rich connotations.

2. Chicago International Manufacturing Technology Exhibition (IMTS) held the first international manufacturing technology exhibition (about 1942) in Chicago before World War II. By 2002, it had been held for 29 times (once every two years). 2002 is the largest and highest level international machine tool exhibition in the history of this exhibition. The exhibition area is130,000 square meters, and 1400 enterprises from more than 30 countries and regions participated in the exhibition. * * CNC machine tools 1308, 47 linkage machine tools with more than five axes. The product embodies high speed, compounding, environmental protection and intelligent technology, and tends to be practical.

3. Europe International Machine Tool Exhibition

1950, the machine tool associations of Europe 12 countries jointly established the European Committee for Machine Tool Industry Cooperation (CECIMO). From 195 1, the European International Machine Tool Exhibition (EMO) will be held. The exhibition is open to the world from 1957. EMO is held in Paris, France, Hanover, Germany and Milan, Italy alternately every two years (single year). The Committee has made strict regulations that no European country can hold a similar international machine tool exhibition within one year of holding the European international machine tool exhibition, and all countries must strictly abide by this regulation. The14th EMO held in hanover, Germany in 200 1 year, with an exhibition area of 19000 square meters, was attended by 2263 enterprises from 36 countries and regions, and thousands of various machine tools and related equipment and accessories were exhibited.

4. Japan International Machine Tool Exhibition (JIMMTOF) held the first JIMMTOF in 1962, and then held it alternately in Tokyo and Osaka every two years. 7 12 companies from 14 countries and regions participated in the 2 1 JIMTOF held in Tokyo International Exhibition Center from June 5 to October 2002. "Collection of new technologies and new products" is the slogan of this exhibition. Compared with the previous JIMTOF, both the mainframe and accessories, including tools and tools, emphasize speed increase, high precision and high rigidity. The compound machining technology developed from centralized process has made a new breakthrough in function expansion and function compounding.
