1) The processing characteristics of the automotive industry include large-scale and assembly line production, and relatively fixed processing conditions. In order to optimize production, improve quality and efficiency, the automotive industry has put forward very strict requirements for the machining efficiency and service life of cutting tools. Meanwhile, due to the use of assembly line operations, in order to avoid the shutdown of the entire production line and huge economic losses caused by tool changes, a mandatory unified tool change method is usually adopted. This also puts forward unique high requirements for the stability of tool quality.

2) The processing characteristics of the aerospace industry include high precision requirements and difficulty in processing materials. The component materials processed in this industry are mostly high-temperature alloys and nickel titanium alloys (such as INCONEL718) with high toughness and strength.

3) Large turbine, steam turbine, generator, and diesel engine production enterprises mostly need to process large and expensive parts. Ensuring the accuracy of the processed parts and minimizing waste is crucial during processing, so imported cutting tools are often used in these industries.

4) As the saying goes, "a good horse is paired with a good saddle." In order to improve machining efficiency and product quality, and fully utilize the efficiency of CNC machine tools, it is often easier to achieve the expected results by using imported cutting tools.

5) Foreign funded enterprises often place greater emphasis on ensuring production efficiency and quality among these enterprises. In addition, there are many other industries, such as the mold industry, military enterprises, etc., where the application of CNC cutting tools is also very common.
