Advantages of Fenike CBN tools in high-speed cutting

With the development of manufacturing technology, the super-hard tool industry has made great progress in recent years, and has entered a new stage of development characterized by the development of high-speed cutting, the development of new cutting processes and processing methods, and the provision of complete sets of technology. It is an important industrial sector in the manufacturing industry, such as the automotive industry, aerospace industry, energy industry, military industry and emerging mold industry, electronics industry and other major processing technologies, and is also an important factor in the rapid development of these industrial sectors. According to expert analysis, new cutting processes such as dry cutting and hard cutting, which are represented by high-speed cutting, have shown many advantages and strong vitality, and become the main way for manufacturing technology to improve processing efficiency and quality and reduce costs.

Therefore, super-hard material tools have an exclusive advantage in the field of high-speed cutting, and their practical applications are increasing. Among these tools, PCD (polycrystalline diamond) tools are the best choice for high-speed cutting of aluminum alloys and non-metallic materials, while diamond-coated tools are not only practical and growing, PCBN (polycrystalline cubic boron nitride) The tool is suitable for cutting cast iron, hardened steel and other materials at higher speeds. CBN (cubic boron nitride) coated tools are also expected to achieve major technological breakthroughs in the near future.

Tool material is key to achieving high speed cutting. High-speed cutting materials mainly include cemented carbide, coated tools, cermets, ceramics, cubic boron nitride and diamond tools. They each have advantages and are suitable for different workpiece materials and different cutting speed ranges. It must be noted that there is an adaptability problem between the tool material and the workpiece material pair, that is, the performance of one tool material and the workpiece material is good, but it is not ideal when processing another workpiece material. In other words, there is no one. The universal tool material is suitable for high speed machining of all workpiece materials.

Workpiece materials suitable for machining with various tools

Diamond tools are suitable for processing non-metallic materials, non-ferrous metals and their alloys. Due to the poor thermal stability of diamond, the hardness is lost when the cutting temperature reaches 800 °C. Because diamond and iron have strong chemical affinity, iron atoms easily interact with carbon atoms at high temperatures to convert them into graphite structures, and the tools are easily damaged. Therefore, diamond tools are not suitable for processing steel materials. Cubic boron carbide (CBN) tools can handle high-speed cutting of hardened steel, bearing steel, high-speed steel, chilled cast iron, and high-speed cutting of high-temperature alloys, thermal spray materials, hard alloys and other difficult-to-machine materials. . The CBN tool is one of the best tools for car grinding.

The integrated polycrystalline (FBN) CBN tool developed by Fenike can be controlled to ±0.01mm and the roughness can be controlled below Ra0.8-1.6μm, which reduces the investment in the purchase of grinding equipment. Complete a series of complex machining operations and shorten the production cycle. Successfully realized the green energy-saving and environmental protection “car-grinding” processing method, which has been widely used in the field of hardened steel and cast iron processing.
