1. PCD metal cutting tool
Types of cutting tools: take turning tools as an example, as well as milling cutters, reamers and boring cutters.
Structural form: this kind of tool can be divided into welding PCD tool and indexable PCD tool. The difference is that the cutting edge material is different, the geometric parameters are different, and the processing objects are different. The indexable PCD blade can be clamped on the corresponding high-precision tool bar, which is mainly used for efficient and mass processing. Under certain conditions, the durability of indexable PCD blades can be increased by dozens to hundreds of times compared with cemented carbide tools.
Geometric parameters: there are two kinds of PCD metal cutting tool ends, one is circular arc, the other is straight line. The adjustment of the arc turning tool in the cutting process is relatively simple, while the adjustment of the flat edge is relatively time-consuming. If it is used in high-precision surface machining, the grinding requirements of arc are very strict, and its accuracy will be copied on the surface.
Typical application: PCD tools can be used for high-speed machining of non-ferrous metals. When processing non-ferrous metals, due to the high hardness of diamond and the small affinity between the surface and metal, the dimensional stability and surface quality of the machining are very good, and the tool life is also long.
2. PCD woodworking cutter
The durability of PCD woodworking tools is more than 100 times that of cemented carbide tools, which can completely replace cemented carbide tools. Other PCD woodworking tools mainly include PCD saw blades, forming milling cutters, etc. However, due to the high price, domestic application is less.
3. PCBN metal cutting tool
The material of PCBN metal cutting tool is cubic boron nitride. Although its hardness is not as high as that of diamond, it is the hardest tool material that can be used to work harden ferrous metals at present.
