The relationship between machine tool industry and China's whole machinery industry is complementary. China's machine tool industry has developed rapidly in a short decade. Five years ago, there was still a great demand for metal band sawing machines in China. Many metal band sawing machine manufacturers were in a state of booming production and sales. However, in the new year, the demand for metal band sawing machines gradually began to decrease, the amount of new orders was greatly different from that before, and the economic benefits began to decrease gradually, In terms of profitability, it began to enter the state of low profitability. Even with the previous bottom, the growth rate of the sales quota of metal band sawing machine still fell by 6.5% compared with last year, and the growth rate of profitability fell by 27.7%. It can be seen from the above that changes have taken place in the metal band sawing machine profession in only one year.

The annual sales quota of metal band sawing machines imported by China's machine tool industry is as high as 20.7 billion yuan, while the export sales quota of metal band sawing machines in China is only 7.3 billion yuan, which is only 13.4 billion yuan. It can be seen that the demand for metal machine tools exists objectively. It is only that China's metal band sawing machine is difficult to meet the needs of users. If the sales quota of import and export can be balanced, China's machine tool industry will earn another 13.4 billion yuan.
