Analysis on the status quo and development of metal cutting tools

Cutting tools are tools used for cutting in machine manufacturing. The vast majority of knives are machine-used, but there are also hand-used ones. Since the tools used in mechanical manufacturing are basically used to cut metal materials, the term “tool” is generally understood as a metal cutting tool. The future development of metal cutting tools is to improve machining efficiency and quality, reduce costs, and shorten the development cycle during the machining process. Therefore, the speed and accuracy of the tools in the future will also be increased. The same demand also arises for precision (or ultra-precision) that can perform fine chipping. ) Technology and tools with more flexible processing methods.

With the large-scale transfer of the developed manufacturing industry to China, and the domestic manufacturing industry has also accelerated the pace of technological transformation, domestic CNC machine tools have begun to enter the manufacturing field in large numbers.

At this stage, cemented carbide tools have occupied the leading position in the developed tool types, with a proportion of up to 70%. However, high-speed steel tools are shrinking at a rate of 1% to 2% per year, and the proportion has now fallen below 30%.

11-15 years of cutting tool industry market size and growth rate

At the same time, cemented carbide cutting tools have become the main tools required by processing companies in my country. They are widely used in heavy industry fields such as automobile and parts production, mold manufacturing, and aerospace. However, Chinese tool companies have blindly and massively The production of high-speed steel knives and some low-end standard knives did not take into account the market saturation and the needs of enterprises. Finally, the mid-to-high-end cutting tool market with high added value and high-tech content was “handed over” to foreign companies.

Development status

At present, China’s cutting tool manufacturing industry has both opportunities and challenges, but overall, favorable factors for the development of the industry occupy a dominant position. Combined with the economic development at home and abroad and the development of China’s cutting tool industry, the demand for cemented carbide in the field of cutting tools has a good prospect.

According to analysis, the level of my country’s cutting processing and tool technology is roughly 15-20 years behind the advanced industrial development. In recent years, the domestic car industry has introduced several production lines with the international level of the 1990s, but the domestic supply rate of the tools used can only reach a low level of 20%. In order to change this situation, my country’s tool industry needs to accelerate the pace of localization of imported tools, and must update its business philosophy, from mainly selling tools to users to providing users with complete sets of cutting technology to solve specific processing problems. . According to the professional advantages of their own products, they must be proficient in the corresponding cutting technology, and constantly innovate and develop new products. The user industry should increase the input of tool costs, make full use of tools to improve efficiency, reduce costs, shorten Intranet/Extranet, and achieve a greater degree of resource (such as cutting database) sharing.

development trend

According to the needs of the development of the manufacturing industry, multi-functional composite tools, high-speed and high-efficiency tools will become the mainstream of tool development. Facing the increasing number of difficult-to-machine materials, the tool industry must improve tool materials, develop new tool materials and more reasonable tool structures.

1. The application of cemented carbide materials and coatings has increased. Fine-grained and ultra-fine-grained cemented carbide materials are the development direction; nano-coating, gradient structure coating and new structure and material coating will greatly improve the performance of cutting tools; the application of physical coating (PVD) continues to increase.

2. Increase in the application of new tool materials. The toughness of tool materials such as ceramics, cermets, silicon nitride ceramics, PCBN, PCD, etc. have been further enhanced, and applications have been increasing.

3. The rapid development of cutting technology. High-speed cutting, hard cutting, and dry cutting continue to develop rapidly, and the scope of application is rapidly expanding.
