Heavy duty machine tool industry has obtained the huge development in the decade years. But from the overall situation of the industry, there is still a large gap compared with foreign advanced technology. Machine stability ,core parts of technical level and other reasons led to be at a disadvantage compared with international competitiveness.

The main reasons are as follows:

1 the ability of independent innovation is weak . The level of core technologies restrict development of the industry.

2 Original innovation and high-quality technical workers are in shortages.

3 Structural imbalances in production capacity leads to the obvious contradiction between supply and demand.
