The **abstract** highlights key developments in the global tool industry, particularly focusing on China's growing role. According to data from the Japan Tool Association, China has emerged as the world’s largest consumer of machine tools, surpassing Japan, the United States, and Italy. In terms of production value, the output of cemented carbide tools has been steadily rising, while high-speed steel tools have shown a declining trend. The trade volume for cemented carbides has also seen a significant increase, with Asia being the primary export destination, followed by Europe, and then North America and other regions.
High-speed machining is now widely accepted as a key technology that boosts productivity and lowers manufacturing costs. The industry is increasingly focused on dry or micro-lubrication methods to reduce environmental impact and operational expenses. For tool manufacturers and coating suppliers, enhancing productivity remains a top priority. Improvements in cutting performance—such as a 20% increase in cutting speed and a 15% reduction in manufacturing costs—are driving demand for more advanced tools. As machining requirements become more complex, there is a growing need for better tool materials, improved coatings, and optimized design.
Currently, domestically produced cemented carbide indexable tools still hold a smaller market share compared to imported alternatives. This can be attributed to several factors. First, many domestic manufacturers lack strong quality awareness, resulting in inconsistent product quality, limited variety, and incomplete specifications. Additionally, the appearance of imported tools is often superior, with better color, texture, and finish. In terms of performance, imported tools tend to offer higher dimensional accuracy, greater stability, longer durability, and better interchangeability. These advantages make them more suitable for precision applications.
Second, pre- and after-sales service in the domestic tool industry is not as comprehensive as that offered by foreign companies. Many international tool providers offer detailed support, including tool selection, supply, adjustment, and timely replacement. Domestic manufacturers often fall short in this area, providing only basic services.
Third, small-scale workshop production still dominates in some domestic factories. Due to economic constraints, these workshops rely on outdated equipment and low-skilled labor, which affects the consistency and quality of the final products. Issues such as poor machining and assembly quality are difficult to resolve, further impacting the reliability of domestic tools.
Experts suggest that the tool industry is entering a new era dominated by cemented carbide materials. Compared to high-speed steel, cemented carbide offers superior performance and higher cutting efficiency. When combined with super-hard materials, it plays a crucial role in modern, efficient machining. Without high-quality tool materials, any innovation in cutting technology would lack a solid foundation. To address this, structural adjustments in the industry are needed, including accelerating the development of hard alloy production bases and enhancing research capabilities in tool development. This will help increase the proportion of cemented carbide tools across all categories.
At the 2014 China International Cemented Carbide Exhibition, a special high-performance technology zone was dedicated to showcasing advanced tool technologies. Exhibitors like Sandvik, Kennametal, Shitaike, Walter, IMC, Mitsubishi, Zhuzhou Diamond, and Xiamen Golden Heron presented their latest innovations. This exhibition featured "green, environmentally friendly, low-carbon, and energy-efficient" projects, offering visitors a glimpse into the future of hard alloy technology. It was one of the most impressive sections of the event, highlighting the rapid progress and potential of the cemented carbide industry.
