Market structure analysis of domestic mechanical cutting too

At present, the domestic mechanical tool structure is out of balance and the demand is not right. For example, there is a large gap in the demand of cemented carbide mechanical tools for users, but the production of high-speed steel mechanical tools is excessive; the gap of high-efficiency mechanical tools in modern manufacturing industry is very large, but the production of low-grade standard mechanical tools is excessive.            In developed countries, cemented carbide mechanical cutting tools have occupied the leading position, with a specific weight of 70%. However, the cutting tool of high speed steel is decreasing by 1% ～ 2% every year, and the proportion has been reduced to less than 30%. The specific gravity of diamond and cubic boron nitride is about 3%.            In 2013, the sales volume of mechanical cutting tools in China was 19 billion yuan, and the proportion of cemented carbide mechanical cutting tools was less than 20%. It was not only far from the product structure of mechanical cutting tools in the international market, but also could not meet the growing demand of domestic manufacturing industry for cemented carbide cutting tools. The proportion of cemented carbide cutting tools consumed by domestic manufacturing industry has reached more than 30%, and the problem of disconnection between supply and demand structure is very serious. As a result, a large number of high-speed steel tools are exported or sold at low prices. However, high-efficiency cemented carbide tools have to rely on a large number of imports. The import volume has increased from US $100 million in 2011 to US $300 million in 2013 (about RMB 1.8 billion).            At present, China's annual output of high-speed steel is about 90000 tons, accounting for about 30% of the global total output, which consumes a lot of precious tungsten, molybdenum and other rare resources. This kind of blind expansion and low-level repetition makes a large number of high-speed steel cutting tools redundant and has to be sold at a low price, resulting in low efficiency of a large number of cutting tool manufacturers.            In terms of economic benefits, the annual sales revenue of cemented carbide in China is about 700 million US dollars; Japan is only 30% of China's output, but the sales revenue is as high as 5.3 billion US dollars, and the proportion of blade (cutter) is as high as 70%, making full use of resources, and enterprises have also obtained good benefits. China's mechanical cutting tool industry should get some useful enlightenment.
