Machine tool for sustainable development in our country, the transformation of the mode of development, improve the level of manufacturing. This is in accordance with the party central committee about us during the "twelfth five-year" to the requirement of the transformation of the mode of development, namely the number will be given a heavier, low value and high consumption of manufacturing industry, to the level of heavy, high value-added, green manufacturing.
Consumption of metal cutting tools in China lasted for 2010 years, in general terms the growth trend of increase in total. According to estimates, 2011 tool consumption in China is about 2011 yuan, about 13% higher than in 2010. Consumption of domestic tool is about 27 billion yuan, less than 4% higher than in 2010; And the consumption of imported cutter is about 12 billion yuan, about 25% higher than in 2010.
But, if we from the consumption structure analysis, we find our domestic tool consumption structure has a lot of problems.
In the worldwide industry, cutting tool, the proportion of consumption is probably: high speed steel cutting tools account for 35%, 10% of diamond and cubic boron nitride cutting tools, and welding carbide cutting tools, solid carbide and indexable carbide is accounted for the rest.
In the tool industry in China is not the case. According to a 2010 machine tool industry association tool branch member enterprise of domestic sales statistics, China's domestic consumption of domestic knives, about 69% is high speed steel cutting tools, carbide cutting tools account for only about 28% (the rest of the system for the tool, diamond and cubic boron nitride cutting tools, etc.). Even with imported cutting tool, cutting tool consumption in our country, about 53% of HSS cutting tools, carbide cutting tools for 45%, and the diamond and cubic boron nitride cutting tool accounts for more than 2%.
Jin Mo cutter net, chief analyst at luo hui pointed out that, although our country has become the world's first large-scale machine tools consumer and is also the world's first large-scale tool consumer, but our tool consumption structure can't even reach the world average. Our present situation is: although our production rate of numerical control machine tool and numerical control machine tool production rate are increased year by year, but the trend of decline from the average selling price of the machine tool, it can be seen that our simple CNC numerical control machine tool may lead. That means the overall level of metal cutting is not high in China.
The current situation of the overall processing level is not high and our rising labor costs, and the trend of appreciation, hidden that we risk losing competitiveness of manufacturing in China, in some countries, including the United States economic scholars and entrepreneurs are considering some has moved to the Asian manufacturing companies to move back to their home.
For example, if we use high performance containing cobalt high speed steel and powder metallurgy HSS (P/MHSS) instead of now used widely in common high speed steel, we manufacture level of high speed steel tools can also be a higher level. Developed countries in Europe and the us since the 1970 s, HSS tool market share gradually eroded by carbide cutting tools. But as the powder metallurgy HSS cutting tools, the advent of high speed steel cutting tool market share and recovered. This is because the powder metallurgy HSS cutting tools compared with common high speed steel cutter, higher hardness, better toughness, wear resistance, so more popular with users. But the large resection in some, such as high impact, processing occasions application field of powder metallurgy HSS cutting tools is smaller than ordinary old type carbide brittleness, fractured is not easy to happen, and therefore in turn replaced part of carbide cutting tools.
