In the pilot plant of Beijing Micro Structure Factory Biotechnology Co., Ltd., staff checked the working condition of the ingredient tank. Xinhua News Agency reporter Ren Chao photographed the single crystal turbine blade production line of Beijing Hanfei Aviation Technology Co., Ltd. How did the interviewee obtain the "pearl on the crown" of the aviation engine blade provided by the photo? How does the "super cell factory" breed materials for building everything? How can the "soft and hard" rocker arm perform well on the operating table? In recent years, more and more "specialized, refined, and innovative" enterprises that master "black technology" have become important support for manufacturing in China. Data shows that China has accumulated more than 12000 specialized, refined, and new "little giants" enterprises, and over 98000 specialized, refined, and new small and medium-sized enterprises. Recently, reporters visited several specialized, refined, and innovative enterprises in Beijing that master "black technology" to glimpse their technological innovation capabilities and broad development potential. The manufacturing technology of blade aviation engines in the sky is known as the "crown of manufacturing", while the manufacturing technology of single crystal turbine blades is the "pearl on the crown". For a long time, only a few countries such as the United States, Britain, France, and Russia have been able to manufacture new aviation engines. To wear a "crown", one must bear its weight: to lift a large aircraft weighing up to a hundred tons and travel in the sky, the aircraft engine needs to provide huge thrust. The power source is the turbine blades, which rotate at over 300 revolutions per second and withstand centrifugal force equivalent to 10000 times the mass of the blades themselves, equivalent to one turbine blade hanging five small cars. With such high-speed rotation, the working temperature of the turbine blades reaches over 1700 degrees Celsius, and steel can easily melt. Turbine blades need to work stably, reliably, and safely for a long time under such complex alternating loads and extreme working conditions. For a long time, this type of exquisite craftsmanship has been a global challenge in terms of mass production, high quality, high efficiency, high qualification rate, and high consistency in processing and manufacturing. Nowadays, Chinese enterprises are able to produce in batches with their internationally leading electrical processing equipment and digital twin technology developed by themselves. The reporter saw on the single crystal turbine blade production line of Beijing Hanfei Aviation Technology Co., Ltd. that more than 100 multi axis electric spark high-speed piercing machine tools are working closely to automatically process. Through the protective window, the electric spark automatically controlled by the machine tool is dancing on the surface of the blade, and the robot shuttles between the machine tool, stacking area, and inspection area. In the control room, the factory's self-developed digital twin technology displays real-time data on the screen, and the adaptive processing instructions for the gas film hole are issued accordingly. This is a single crystal turbine blade, which is a key core component of new aviation engines and gas turbines, and is the 'source of power'. Our work at Hanfei Company is like installing air conditioning for aircraft engines, creating 'capillaries' for single crystal turbine blades, and cooling and cooling the turbine blades. "The person in charge of Beijing Hanfei Aviation Technology Co., Ltd. pointed to a metal component the size of a palm. A single crystal turbine guide blade has several hundred or even thousands of axial directions, varying inlet and outlet angles, non-uniform distribution of positions, and different shapes of gas film holes. Additionally, the blade has a complex cooling system inside, and the inner wall of the inner cavity should not be damaged when machining the gas film holes. If there is a slight deviation during drilling, the turbine blade will burn out under high-temperature and high-speed conditions, and the aircraft can
