The essence of green manufacturing is the problem of efficient use of energy and the development of new energy. Superhard materials and products are industrial consumables in the field of product processing, and their performance largely affects the production of green GDP. Due to the high processing efficiency, high processing quality and low pollution energy consumption of super-hard materials and products, it will play a major role in reducing industrial energy consumption. Cutting tools are widely used in industrial production processes. Now the level of machining industry is increasing day by day, and the industry has put forward new requirements for tools. In addition to the improvement of process technology, green and sustainable production has become a new trend. In addition to increasing the service life, the tool products are also required to reduce the contamination during cutting, and dry cutting is used whenever possible. When the cutting fluid cannot be completely eliminated, it is best to contain only the rust preventive agent and no organic matter, which can greatly reduce the cost of recycling.
The variety of cutting tools and the characteristics of the working state during use determine the difference in the choice of tool plating. Different from turning and drilling, the milling cutter should also consider the characteristics of its intermittent impact. Early development of the coating is mainly focused on wear resistance, with hardness as the main indicator. Such coatings represented by titanium nitride have a high coefficient of friction, and a constant friction between the workpiece and the workpiece during processing will generate a large amount of heat energy.
In order to avoid the tool overheating and deformation, which affects the machining accuracy and prolongs its service life, cutting fluid is usually used. To solve the problem of reducing or eliminating cutting fluids, cutting fluids, especially those containing oil, have become a huge burden. Regardless of how safe and environmentally friendly a cutting fluid is, the government decree will still require you to perform special treatment from the moment you dump it into the pool. Even if the local government allows you to dump clean, oil-free synthetic fluid from the bucket into the drain, it becomes a controlled industrial waste once it is mixed with the oil and metal debris contained in the machine. Not only does the US Environmental Protection Agency manage the handling of this mixture, but many state and local governments have also classified them as hazardous waste, and if they contain oil and certain alloys, they must be tightened. Therefore, it is necessary to find a tool that does not need to add cutting fluid, and also meet the processing needs of the production, a super hard cbn tool came into being. It is a kind of PCBN superhard tool series developed and manufactured by Fu Nike Superhard Materials Co., Ltd., which does not need to add cutting fluid and can meet the high speed and high cutting processing method. It is a kind of tool with high efficiency and environmental protection without adding cutting fluid, due to its hardness. This is only diamond, it still has excellent red hardness at temperatures up to 2000 ° C, although it is more brittle than cemented carbide, and its thermal conductivity and chemical stability are lower than ceramics, it has a higher impact than ceramic tools. Strength and resistance to cracking, as well as the ability to cut hard metals on lower rigidity machines. This also makes CBN superhard tools widely used in the difficult materials industry.
With the super-hard tools such as super-hard tools and high-speed CBN grinding wheels, they also have unique energy-saving advantages in green manufacturing. The market for super-hard materials and green products also has great potential. According to reports, the current annual output of super-hard tools and PCBN cutting tools in China is 400,000, and the sales volume is less than 200 million US dollars. The investigation by authoritative departments shows that the two kinds of tools are potentially marketed. The total will exceed $1.5 billion.
