China has become the largest consumer of machine tool tools in the world

From the statistics of the tool industry, we can see that the proportion of cemented carbide will gradually increase in the future. The rate of high-speed steel products will gradually decrease. According to the statistics of the Japan Tool Association, China has become the world's largest consumer of machine tools, followed by Japan, the United States, and Italy. Judging from the output value of the tool, the output of cemented carbide cutting tools has continued to increase in recent years, while high-speed steel cutting tools have begun to show a downward trend, and the import and export volume of cemented carbide has increased significantly. The main export target is Asia, followed by Europe, and then North America and other regions.

High-speed machining has been widely considered as a processing technology that increases production and reduces manufacturing costs. The concept of dry processing or trace lubrication is the main goal of the processing industry today to reduce environmental protection and production costs. For tool manufacturers and coating suppliers, the most important is productivity. The cutting performance (cutting speed, cutting amount per unit time) is increased by 20%, and the manufacturing cost is reduced by 15%. Increasingly stringent processing requirements require the further development of tool materials and coatings, improved processing conditions, and improved tool design.

The current challenges and areas for improvement include: mechanical and structural properties: hardness, strength, abrasion resistance; thermal and chemical properties: heat resistance, insulation, catalytic properties; biological properties: adaptability, insecticidal properties Electronic and optical properties: reflective, transparent and so on. In recent years, (Ti, Al) coated carbide cutting tools have occupied a dominant position in the high performance tool market. The high demand in some special applications promotes the development of special coatings or precision coatings.
