In recent years, with the continuous development of machining workpiece materials, especially the emergence of difficult-to-machine materials, superhard material tools have been more and more widely used. The number, scale, and manufacturing level of domestic superhard material tool manufacturers In the rapid increase. The exhibition of superhard materials and products at the China (Zhengzhou) International Abrasives Grinding Exhibition 2011 held on November 11-13 will include Henan Fenike, Zhengzhou Bote, Zhengzhou Sanmao, Zhengzhou Diamond, Zhongnan Diamond, and Zhengzhou. Hua Jing and other dozens of superhard material and cutting tool manufacturers have shown to the audience the rapid development and great progress of domestic superhard materials.
In the current tool market, the tool materials occupying the largest market share are still high-speed steels and hard alloys. However, the hardness of these tools is only 2,000 to 3000 HV. If adhesive materials are added, the overall hardness is below 2000 HV. For hard-to-machine materials and high-speed, high-precision machining, lower hardness tool materials are no longer adequate. Super hard material tools represented by diamonds and cubic boron nitride (CBN) quickly occupied this market. Among them, diamond has extremely high hardness and wear resistance, and its hardness can reach 10000 HV. It is the hardest among tool materials and its thermal stability can reach 700°C to 800°C. The hardness of cubic boron nitride is second only to diamond (up to 8000HV-9000HV), and its thermal stability is higher (up to 1250°C to 1350°C).
The reporter learned from the interview that the super-hard material cutter has the characteristics of high processing efficiency, long service life, and good processing quality. In the past, it was mainly used for finishing. In recent years, due to the improvement of the production process of man-made superhard cutting tool materials, it has been controlled. Raw material purity and grain size, using composite materials and hot-pressing technology, etc., have expanded in scope of application, and can be used for rough machining in addition to normal finishing and semi-finishing, and it is internationally recognized as improving productivity at the present time. One of the most promising tool materials. Using superhard materials to process steel, cast iron, non-ferrous metals, and alloys, etc., the cutting speed can be an order of magnitude higher than that of cemented carbides, and tool life can be tens or even hundreds of times higher than that of cemented carbides. At the same time, its appearance also changes the traditional concept of the process. The use of super-hard tools can often be carried out directly on the car or on the milling (or polishing) process. The hardened parts can be processed, and a single process can be used instead of multiple processes, which greatly shortens the process flow. .
Zhang Taihe, chief engineer of Henan Fukenike Superhard Material Co., Ltd., told reporters that diamond tools have extremely high hardness and wear resistance, and can effectively process nonferrous metals such as copper and aluminum and their alloys, ceramics, and sintered hard materials. Alloys, various fibers and particle reinforced composites. Compared with diamond, cubic boron nitride has higher thermal stability, chemical inertness to iron group elements, strong anti-bonding ability, and is more suitable for processing various hardened steels, thermal spray materials, chilled cast irons and HRC35 and above. Cobalt-based and nickel-based hard-to-cut materials.
Nowadays, the advantages of super-hard material cutting tools in cutting machining have been well known by the masses of users, and have been more and more widely recognized and applied. The market demand is huge. Judging from the superhard material itself, China has obvious resource advantages. Diamond production accounts for more than 80% of the world's total production, and cubic boron nitride (CBN) production accounts for more than 60% of the world's total output. It is already the world's largest super In hard-material-producing countries, China has entered the ranks of the world’s most powerful countries in terms of superhard materials, and China’s superhard material industry has taken the lead in becoming one of the industries that have the right to speak in the world. However, in fact, currently domestic superhard material tools are still in the starting and growing stage. Some companies are working hard in the direction of high-end, precision superhard material tools, and have achieved a lot, but still can not meet the growing market demand. In the future tool market, superhard material tools will occupy a more important market position.
