There is a significant gap between the Chinese tool industry and foreign countries

China's cutting tool industry has experienced extensive and rapid development for more than ten years. The contradictions such as overcapacity, redundant construction, and low-price competition are increasingly exposed, especially in the period when the industry is facing structural adjustments and product upgrading, which seriously restricts the machine tool industry. The healthy and orderly development of the industry. However, foreign cutters dominate the world, and the situation of firmly occupying the market has not changed. In this issue, Sandvik Coromant, Iscar, Walter and HORN tools are taken as examples to explore the uniqueness of these cutting tool companies in terms of products and technology.

There are many challenges to overcome when milling stainless steel, including many difficulties in chip formation, tool life, and productivity. Overcoming these challenges requires a light cutting process and low cutting forces. The latest insert geometry for the Sandvik Coromant CoroMill 345® is designed specifically for this purpose. The inserts not only achieve higher metal removal rates and greater throughput, but they can also be used in small taper machine tools (ISO 30 and ISO 40 machines) as well as in applications where vibration is prone to or in the presence of weak fixtures.

The manufacture and processing of turbocharger components is very complex and puts forward a high productivity demand for manufacturers, but at the same time it places particular emphasis on process reliability. Iscar Germany uses innovative tools to support manufacturers and obtain more economical, safer and more reliable machining. And for any particular material to be machined with special requirements for the cutting tool, such as different coatings and tools suitable for their processing characteristics are provided.

Walter Prototyp MC326 and MC726 use a new cutting material WK40TF made of a tougher carbide substrate and a new TiAlN coating combined with special cutting edge pretreatment technology. Double the performance - 100% increase in tool life, or 100% increase in cutting speed, at the same production efficiency.

Compared with these foreign tools, we do have a big gap. Domestic tool companies should focus on technology research and development and innovation, improve product technology, increase product added value, and strive to raise the standards of the entire industry, strengthen the ability of solidarity and cooperation among enterprises and catch up.
