at present Oil cylinder manufacturer The machining manufacturing industry such as boring and milling is developing at a high speed in China. Through constant introduction of foreign high-tech and continuous innovation and development, brilliant achievements have been made in the past half century.

Recently, we learned from the General Machinery Processing Industry Association that boring and milling is widely used in metallurgy, mining, pharmaceutical, processing, automobile, shipbuilding and other fields,

According to the statistics, the whole industry achieved sales of 5 billion yuan and exports of about 500 million dollars. Experts predict that due to the overall economic development of the country during the "Twelfth Five Year Plan" period, the growth rate of the economic aggregate of the boring and milling machinery manufacturing industry will still exceed double digits, especially the investment in infrastructure has accelerated the development of metallurgy, electricity, construction machinery, energy, etc. Therefore, the demand for boring and milling technology will further expand.

With the further increase of national infrastructure construction, the boring and milling technology in China has developed rapidly in recent years. The industry has undergone great changes. The changes from scratch, from small to large, from weak to strong have been gradually expanded and developed. Through reform and opening up, a complete set of boring and milling processing industrial system integrating design, production and sales has been gradually established. Through digestion and absorption of advanced technology, scientific and technological breakthrough and transformation have been strengthened, The independent development capability and international competitiveness of a number of key backbone enterprises have improved significantly, and a number of national major technical equipment have been localized, making important contributions to the development of the national economy.
