3 CBN300 milling processing example
The CBN300 works best when milling gray cast iron, with a tool life four times that of a typical PCBN insert. For plants that are using ceramic inserts, the CBN300 can increase tool life by 50 times and cut line speeds of up to 2000 m/min. In recent years, PCBN has demonstrated extraordinary characteristics in the face milling of pearlite gray cast iron engines. We have successfully applied CBN300 to the milling engine block plane of the newly built engine flexible production line of Shanghai General Motors Corporation (SGM). The milling line speed vc reaches 1600m/min, even up to 2000m/min, which not only greatly improves the machining efficiency of the engine, but also shortens the processing time, thus improving the adaptability of the engine production line. Table 3 compares the plane cutting parameters of CBN300 and cemented carbide milled gray cast iron engine blocks. Shows the excellent quality of PCBN milling cutters to improve processing efficiency.
4 Conclusion
The 21st century is a high-tech era. Products must have high performance and high quality to have a market, and enterprises can have vitality. To this end, the level of manufacturing technology should be improved as soon as possible. For the metal processing industry, the promotion of the use of PCBN tools to improve manufacturing technology is a powerful measure, and the promotion and application of new technologies and products requires not only the strong support and support of relevant authorities, but also the systematic and planned promotion of PCBN. The technical support and use of the tool also requires users to accept new materials and new technologies and change the old production concepts and management methods. At present, the average cost of tools is very low, accounting for only about 1/100 of the cost of the product. If you do not improve production efficiency and ensure product quality, it will limit the production of high-quality and efficient tool applications and advanced equipment. Practice has proved that the effectiveness of PCBN tools can not only improve the processing quality of products, but also improve economic efficiency.
