With the rapid development of the modern technology, ferrous metal and composite materials become widely used, and difficult to machine materials appear more and more, and it also requires high on the cutting tools and other process.
High Speed Machining is one type technology which used for high speed with high efficiency.
The advantages of high speed cutting
(1) Reduce the processing time, improve the processing efficiency
(2) High Precision, and the cutting force will reduce 30%, and reduce the surface harm, and make the workpiece have good surface roughness and other performance.
(3) It can overcome the defect of the cutting tools wear easily, and extand the tool life.
The choice of the high speed cutting tools
In the high speed process, the cutting tools are the most important, is the base that the high cutting speed process will have excellent performance. We can see that realize high speed cutting is one of the key factors.
In the process, the cutting tools need high precision, strength, impact resistance and high temperature performance and others. In current times, PCD and CBN is the represent of the cutting tools which can realize high cutting speed.
Coating Insert, Nano-multilayer structure coating is generally composed of two kinds of different thickness on the nano-scale material or structure of the non-uniform coating system, with high-speed cutting environment to adapt to the characteristics of good mechanical properties.
PCD and CBN Insert: Diamond is the hardest materials in the world, CBN only second to diamond, both of them called superhard cutting tools. They have higher hardness and better wear resistance, is the first choice for high speed field. BNK30 is the represent of high speed cutting tools for machining gray cast iron, and BN-S300 is the represent for high speed milling.
BNK30 belong to brazed pcbn insert, use nano binder and high pune particle cubic boron nitride, and can be used for machining gray cast iron parts with high cutting speed. BN-S300 belong to solid cbn insert, and it can make sure good surface roughness and dimension accuracy,and the tool life will be several times of other common product.
Conclusion
High-speed cutting machine processing technology is a new, advanced manufacturing technology, the high-speed cutting of non-metallic materials and composite materials is to achieve high precision, high efficiency, high stability and low surface finish cutting important technology. At the same time, China superhard materials are making research on high-speed cutting tools, and promote China’s rapid development of high-speed cutting technology.
