Chinese knife tool industry innovation and industry transformation
- Jul 18, 2018 -

First, about product structure adjustment. Nowadays, knife tool materials have entered the era of hard alloys. Compared with high-speed steel, tungsten carbide has better performance and higher cutting efficiency. Together with super-hard tool materials, it is realized by modern cutting technology. The most important guarantee for efficient processing. At present, the proportion of cemented carbide tools in China is about 40%, far lower than the level of industrial developed countries, which restricts the improvement of the overall level of China's tool products. Without good tooling materials, any advancement in tooling and advances in cutting processes lacks the necessary material basis and can only be found in the air. However, to fundamentally solve this problem involves the adjustment of the industry structure. It is necessary to speed up the construction process of production bases with cemented carbide materials and tool development capabilities, and rapidly increase the proportion of cemented carbide tools in all tools. This is a project that requires a lot of investment and requires the guidance and support of relevant government departments.


Second, we must pay attention to the problem of tool innovation. Tool innovation is the most important factor driving advances in cutting technology and improving cutting efficiency.


The innovation of modern machine knives is manifested in three aspects:

First, the innovation of material grades. It accounts for a large proportion of current tool innovations. Some large foreign companies with hard alloys and superhard materials development and production capacity will introduce a large number of new tool materials every year, which will become the main selling point of their new tool products. The development idea is that, according to the characteristics and requirements of the application field, the advantages of integrating materials, coatings and troughs, the development of “the right medicine” can make the blade have performance advantages in a certain application range, and obtain good processing results. The processing efficiency can be improved by more than 20%. Therefore, it is imperative to accelerate the construction of China's cemented carbide tool material research and development production base.


Second, innovation in tool coatings. Tool coating technology has evolved very rapidly since coating technology entered the tooling field. As the coating process, equipment, and component innovations continue to accelerate, its modification of the tool is also increasing. Because the coating technology has the characteristics of improving the performance of the tool, the flexibility of the process, and the rapid development of the new grade, not only the cutting performance of the tool has been greatly improved and improved, but also the innovation of the blade coating grade is fast and good. Coatings have become the most important factor driving advances in cutting technology. Up to now, China has not possessed the independent development capability of tool coating equipment and technology, which has restricted the progress of cutting technology in China and the innovation of coating grade. Therefore, it is imperative to vigorously develop tool coating technology.


Third, innovation in tool structure. At present, the momentum of tool structure innovation is very strong and shows great potential. In the machine tool exhibitions in recent years, the new structure of various tools that the tool manufacturers are competing to launch has become the highlight of everyone's attention. The innovative tool structure not only improves the tool performance, but also has a great impact on the development of the tool variety. The emergence of each new type of tool will cause great concern in the industry, and will be rapidly promoted and applied in the industry, which will greatly promote the development of tool varieties and improve tool performance. Many tool companies in China only make tools and do not produce tool materials, so we must pay more attention to the innovation of tool structure.


At present, there is still much work to be done to accelerate China's tool innovation. In addition to updating the hardware and equipment, we must pay attention to the following two aspects.


On the one hand, it is necessary to improve the metal cutting knowledge and skill level of the tool practitioners (including the design, manufacture, marketing, service and other aspects of the tool).


On the other hand, we must accelerate the transformation of the tool industry. We must complete the transformation from traditional tool manufacturers to manufacturing-oriented, user-oriented manufacturing cutting technology service providers, as well as processing efficiency and efficiency providers.
