Recently, the feature report titled "Industrial Mother Machine Promotes 'Extreme Manufacturing'" given by the program "Economic Half-hour" of CCTV-2, a financial channel of CCTV, offered in-depth coverage of the achievements made by Zhuzhou Cemented Carbide Cutting Tools Co., Ltd. affiliated to China Minmetals, as an enterprise supporting industrial mother machines, in continuously tackling core technologies and promoting the manufacturing of high-end equipment in the country. The report has drawn widespread attention.
It is pointed out in the report that Zhuzhou Cemented Carbide Cutting Tools Co., Ltd. has achieved fruitful results in technology innovation of cutting tools. It is also noted that the company has relied on its self-developed coating technology to extend the life of cutting tools by 5-10 times and improve cutting efficiency by about 70%, and therefore improved the performance of cutting tools significantly.
Luo Xuequan, a researcher of CVD coating technology at the company, said in the video, "The Vickers hardness of general steel is below 800, while the Vickers hardness of cutting tools for steel, cemented carbide, is above 1,600. The coating hardness of our blade is even higher than the hardness of cemented carbide blades, and its Vickers hardness can reach over 3,000."
In the face of foreign monopoly of high-end coating technology, the company has taken a new approach by relying on the resources and platforms of China Minmetals. Within three years, it has tackled the low-pressure CVD coating technology, optimized milling tools, and launched the first coated turning tool, of which the technology and performance has reached the advanced level in the world.
Qu Jun, the research team leader of CVD coating technology at the company, said in the video, "The product we have developed has reached the international advanced level in both technology and performance. In this field, we have gone from catching up to running in parallel now."
At present, the company has applied for more than 20 invention patents, and its products have been widely used in the field of "extreme manufacturing". In the past 5 years, its R&D investment has exceeded 600 million RMB, accounting for more than 6% of its annual sales revenue. In 2023, it produced 120 million blades, which were sold to more than 80 countries. In 2024, it was awarded the single champion enterprise in the national manufacturing industry, shaping the brand of high-end cutting tools with excellent quality and innovation capabilities, and demonstrating the strength of "Intelligent Manufacturing in China" on the international stage.
