Looking at Tool Consumption Trends in the Automotive Industry from Carbide Tools

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 adopted because of the increasing demand for auto parts materials. Among the tool materials selected by domestic automobile users, the most used tool is a carbide tool, accounting for 64.1%.

With the development of super-hard tools, hard turning is gaining popularity as a good alternative to grinding economics. Compared with the first survey, the use rate of superhard tools has been significantly improved. For example, machining of cylinder bores uses cubic boron nitride inserts in many semi-finishing and fine boring operations. The cutting speed reaches a new height. Tool life is also greatly extended.

The automotive industry adopts high-volume, assembly line production, and the processing conditions are relatively fixed, which places very stringent requirements on the machining efficiency, service life, and stability of the tools. In recent years, with the large-scale application of lightweight materials in the automotive industry, such as aluminum alloys, composite materials, etc., the application of diamond tools has also increased substantially: For example, in some machining processes of gearbox housings, the previously used carbide alloys will be used. Knife changed to diamond tools, tool life can be increased to tens of thousands of pieces, and its economic benefits are very obvious. Due to its extremely high hardness, diamond tools have a very long service life when machining aluminum workpieces and other non-ferrous metals and their alloys. In addition, ceramic cutting tools are also a promising tool that is currently being used in the automotive industry due to its high hardness and competitive price.

The tools that can be indexed have been promoted in China for many years and have progressed smoothly. However, the development is still unbalanced. In this survey, the user coverage rate is still lower than the overall tool and welding tools. However, the technology of indexable cutting tools in our country has made new progress in the promotion process, and there is great potential for rapid application of varieties.

The rapid development of modern automotive manufacturing machinery processing and cutting tool technology, high-tech has been widely used, in the processing technology, cutting methods, tool structure, tool materials, tool coating and other aspects have been with the traditional mechanical processing Different points. New tool structures and inserts with new cutting edges and geometries have been continuously researched and developed to accommodate CNC machine tools and tool holders for high-speed machining and their connection to machine tools such as HSK holders, hot-set holders, hydraulics Tool holders and other new tool holders are widely used. In order to increase production efficiency and reduce tool change time, various compound tools, such as drill boring compound, drill reamer compounding, drilling and thread machining compounding, are increasingly used in the processing of automotive parts. The unfolding tool satisfies many special machining requirements, and some of the tools have even developed into a machine, electric, and hydraulic integrated device, which has gone far beyond the traditional tool concept.
