In terms of tool materials, superhard tool materials such as CBN (cubic boron nitride), PCD (polycrystalline diamond) tools and new carbide tools have been widely used due to the increased demand for automotive parts. Among the tool materials selected by domestic car users, the most used are carbide tools, accounting for 64.1%.
With the development of superhard tools, hard turning is becoming popular as an economical alternative to grinding. Compared with the first survey, the use rate of super-hard tools has been significantly improved. For example, the machining of cylinder bores has adopted cubic boron nitride inserts in the semi-finishing and finishing processes, and the cutting speed has reached a new height. The tool life is also greatly extended.
The automotive industry uses large-volume, assembly line production, and the processing conditions are relatively fixed, which imposes very demanding requirements on the processing efficiency, service life and stability of the tool. In recent years, with the large application of lightweight materials in the automotive industry, such as aluminum alloys, composite materials, etc., the application of diamond tools has also increased significantly: as in the processing of some parts of the gearbox housing, the original used carbidesé•—The knife is changed to a diamond tool, and the tool life can be increased to tens of thousands of pieces. The economic benefit is very obvious. Due to their extremely high hardness, diamond tools have a very high service life when processing aluminum workpieces and other non-ferrous metals and their alloys. In addition, ceramic knives are also a promising tool that is currently being used in the automotive industry due to its high hardness and competitive price.

Here is a brief talk about indexable tools. The indexable tool has been promoted in China for many years and is progressing smoothly, but the development is still unbalanced. The user coverage in this survey is still lower than the overall tool and welding tool. However, the technology of indexable cutting tools in China has made new progress in the process of promotion, and the application potential of rapid increase in variety is great.
The mechanical processing of modern automobile manufacturing industry and the tool technology used by it have developed rapidly. High-tech has been widely used. In the aspects of machining technology, cutting method, tool structure, tool material, tool coating, etc., it has been much different from the traditional machining in the past. The difference. New tool structures and inserts with new cutting edges and geometries have been continuously researched and developed to accommodate tool holders for CNC machine tools and high-speed machining and their connection to machine tools such as HSK tool holders, hot-sleeve holders, hydraulics Tool holders and other new tool holders are widely used. In order to improve production efficiency and reduce tool change time, various composite tools such as drill collar compound, drill hinge compound, drilling and thread processing compound are used more and more in the processing of automobile parts. The unfolding tool meets many special machining requirements, and some tools have even evolved into a machine, electric and hydraulic integrated device, which has far surpassed the traditional tool concept.
