Current development status of PCD/PCBN tools at home and abroad
At present, foreign advanced countries have already put into use PCD/PCBN tools on a large scale, which is inseparable from the rapid development of foreign high-speed CNC machine tools in the past 20 years, especially in the automotive industry, foreign PCD/PCBN tools have already occupied the tools. More than 30% of the market share. PCD/PCBN tools are especially suitable for CNC automatic machining line applications such as the automotive industry due to their high hardness, high wear resistance, good thermal conductivity and low friction coefficient.
Compared with foreign countries, the current domestic PCD/PCBN tools are not well developed. This is due to the fact that the domestic tool companies are not equipped with the level of manufacturing equipment and manufacturing technology, which restricts the use and promotion of these tools; foreign PCD/PCBN tools are The expensive price causes many users to be discouraged; the technical habits of enterprise technicians and the awareness of new technologies are not enough, and the tool performance, processing mechanism and using technology of PCD/PCBN tools are not fully understood and mastered.
However, from the experience of foreign success, coupled with the advantages of high-speed, high-precision, car-based grinding and green manufacturing of PCD/PCBN tools in the field of machining, it will be like the development of high-speed CNC machine tools in China. The trend is unstoppable.
Application advantages of PCD/PCBN tools in the automotive industry
The automotive industry is the best application area for PCD/PCBN tools. In recent years, with the continuous development of China's automobile industry, the automotive industry has become an important pillar of the national economy. PCD/PCBN tools can be used with high-speed CNC machine tools to shorten non-machining time. More than half of the time, but also reduce non-machining time, increase machine tool life and improve processing efficiency.
At present, foreign PCD/PCBN tools are used in the machining of cylinder blocks, cylinder heads, axles, gearboxes, bearing covers and other parts. For the shaft, gear and wear ring, the PCBN tool is very convenient for turning, and it is also a place that is well done abroad.
Trends in PCD/PCBN tools
We expect that China's tool market share will reach almost 360 billion during the 12th Five-Year Plan period. According to the current market share of superhard materials, accounting for more than 10%, the PCD/PCBN tool market share will reach nearly 40 within five years. Billion, this is a huge cake to be developed for all superhard material tool companies.
PCD/PCBN represents the development direction of tool materials and is an ideal cutting tool material. It is an inevitable trend to replace non-renewable and increasingly scarce carbide tool. It is believed that through the unremitting efforts of domestic enterprises and scientific research institutions, China's super-hard material cutting tools business will have a brighter future, and PCD/PCBN cutting tools will go farther and stronger in cutting processing.
China University of Mining and Technology (Beijing) Superhard Tool Materials Research Institute
China University of Mining and Technology (Beijing) Superhard Tool Materials Research Institute was established in 2005, specializing in the research and manufacture of superhard materials, carbon nanomaterials and powder metallurgy. After more than 6 years of research and experimentation, we have made major breakthroughs in PCBN tool materials. In 2007, we won the first prize of Science and Technology Progress Award of Chaoyang District of Beijing and the second prize of Science and Technology Progress of Ministry of Education in 2011. Especially in the past three years, the Institute of Superhard Materials of the University of Mines has achieved breakthroughs in the research under the support of national issues. The PCBN material tools currently developed have comparable performance with foreign advanced brands. We hope that by combining with the market, the domestic superhard material tool industry will develop faster.
