consolidation of the domestic Abrasive
In the entrance area to cut pieces as monomers, and its share of China's import growth still equal good. 2010 China's machine tool imports despite a substantial increase in imports of manufactured abrasive roll goods organs but not reasonable, high-grade resources, high energy consumption of products accounted for a large proportion of imported products subject to further beautify the organization.
China Machine Tool Equipment wealth Association statistics show that in 2010 China's machine tool import totaled $ 7.03 billion, an increase of 48.4%, of which metal processing machine tool imports $ 1.85 billion, an increase of 31.3%, significantly lower than the growth rate grinding wheel manufacture of its machine tool manufacturing Works growth. In the export of products, abrasives imports continued rapid increase, of 15.3 billion U.S. dollars, an increase of 100 percent, and cutting tools, tool machine tool industry to become the largest amount of manufactured goods imported two types of system works, machine tool equipment, manufactured goods accounted for Entrance amount of 44.6%.
In these two types of manufactured goods, high-end non woven abrasive resources such as abrasives and cutting tools, high energy consumption products occupy a large proportion of the absolute value of the machine at a higher proportion of imported products are getting smaller, accounting for only 26.3% low compared to 2009 by 3.4 percentage points over the same period, imports of product structure management status differences have not been changed.
