The development of cemented carbide cutting tools in my country is still lacking

China has become the world's most promising tool market, and many multinational tool groups are also in the development strategy of the post-crisis era. Centers, training centers, logistics centers, etc. have settled in China one after another, so as to radiate Asia with China as the center, serve customers more directly and conveniently, and better meet the special needs of customers in the Asia-Pacific region. Luo Baihui, secretary general of the International Mould and Hardware and Plastic Industry Suppliers Association, believes that the main reason why the Chinese market has received such attention is that the Chinese market's sales share is taking up an increasing proportion of its global market share.

At present, Chinese tool companies have occupied half of the market through continuous learning and strategic planning. However, in the process of development, the company still highlights several fatal problems. development and progress.

At this stage, cemented carbide cutting tools have occupied the leading position of cutting tool types in developed countries, with a proportion of up to 70%. However, high-speed steel tools are shrinking at an annual rate of 1% to 2%, and the proportion has dropped to below 30%.

At the same time, cemented carbide cutting tools have become the main tools required by processing enterprises in my country, and are widely used in heavy industries such as automobile and parts production, mold manufacturing, aerospace, etc., but Chinese tool enterprises blindly and massively The production of high-speed steel knives and some low-grade standard knives does not take into account the market saturation and the needs of enterprises, and finally "hands over" the high-end knives market with high added value and high-tech content to foreign enterprises.

According to some data, the current annual sales of cutting tools in my country is about 14.5 billion yuan, of which cemented carbide cutting tools account for less than 25%, but the cemented carbide cutting tools required by the domestic manufacturing industry have accounted for more than 50% of the cutting tools. This kind of blind production has seriously failed to meet the increasing demand for cemented carbide tools in the domestic manufacturing industry, thus forming a vacuum state in the mid-to-high-end market, which is eventually occupied by foreign companies.

In 2007, of the 16,500 tons of cemented carbide produced in my country, 4,500 tons were used in the production of cutting tools, and the quantity was comparable to that of Japan. However, the value of the tool after making it is only 800 million US dollars, far less than Japan's 2.5 billion US dollars, which fully shows that the overall production level of domestic high-efficiency carbide tools still has a considerable gap with foreign countries. Therefore, under the premise that domestic enterprises cannot meet the market demand, the demand of the manufacturing industry has to be solved by a large number of imports.

The annual sales growth rate of major foreign businessmen in China's mid-to-high-end tool market has reached 30%, which has exceeded the average annual growth level of domestic tools.

On the 150th anniversary of the establishment of Sandvik Group, in order to celebrate this grand ceremony and continue to inherit Sandvik's century-old accumulation in talent training, Sandvik Coromant, the world's No. Witnessing the wonderful, welcoming the future" as the theme, invited 150 mechanical or numerical control students from colleges and universities in 9 cities across the country to participate in its cutting summer camps held in Guangzhou, Shanghai, Beijing and Wuhan. Encourage young students to join the machining industry and lay a solid foundation for promoting the transformation and upgrading of China's manufacturing industry.

Nearly 120 teachers and students from 18 colleges and universities including Guangzhou Mechanical and Electrical Technician College, Shanghai Jiaotong University, Beihang University and other universities visited modern machining workshops and key universities during the summer camps at Guangzhou Station, Shanghai Station and Beijing Station. In the laboratory, and listen carefully to the special lectures on the application of cutting tool technology by engineers in yellow coats, carefully observe the on-site demonstration of modern milling art parts processing, personally participate in the assembly and disassembly of typical carbide tools, and experience the world's leading edge in a close-up and all-round way machining technology.
