              There is a big gap between China's machine tool companies and foreign countries

              Publish: 2014-03-13

              It is understood that although China is a global leader in the production and demand of machine tools, most of the domestic machine tools are based on ordinary machine tools and have low numerical coverage. Therefore, the development of high-end machine tools is one of the key development goals of China's machine tool industry. China's high-end machine tools The road is developing vigorously.

              Compared with advanced foreign companies, China's machine tool companies still have a big gap. Although some of our companies have developed medium-to-high grades, most of them are still assembled on the basis of the domestic machine tool manufacturing and importing key functional components. It shows that we have mastered the overall R&D and manufacturing technologies for mid-to-high grade and key functional components. Affected by R&D capabilities, 80% of domestic high-end CNC systems, 90% of high-end CNC systems, and 85% of high-grade products are dependent on Imported abroad.

              The main reasons for the large gap between China's machine tool companies and foreign countries are:

              First, industrial development is related to the past political environment. In the past, the degree of state support was not enough, and the idea of quick success for enterprises was serious, leading to heavy hosting and light components.

              Second, there is little research investment and the foundation is weak. In some key component fields, some of our companies can only use high-precision functional components made of ordinary machine tools. Although these products can also be used on some high-end products, their accuracy and retention cannot be improved. On the issues of raw materials and the level of technology, and foreign advanced components can be used for three years does not change, the domestic components may only be used for one and a half years to be replaced, which also contributed to the low market share of domestic functional components.

              Third, the key components, accessories determine the development of the host. Only the key components and accessories have been developed to a higher level, and the self-provisioning rate of key functional components has increased. Only in this way can we form a group of machine tool manufacturers that are relatively competitive internationally. We must accelerate the pace of innovation and upgrade of machine tool technology. This will also become the most important task for China's manufacturing industry.

              The next few years will be the key to China's deep implementation of the industrial transformation and upgrading plan and strategic emerging industry development plan. High-end machine tool manufacturing industry will usher in an important period of development opportunities. Under the encouragement and support of national policies, machine tool companies should strengthen differentiation. Competitive advantage, in order to stabilize the market share already obtained, only in the cost, technology, sales channels and services, there are differences in the competitive advantage of the company in order to be in the fierce market competition in the future to occupy an advantage.
