Domestic CNC machine tools for Boeing custom engine blades

The Boeing aircraft engine blades, a critical component of the American aerospace giant's fleet, were actually manufactured using "Sichuan-made" CNC machine tools. According to a report from the Provincial Department of Commerce, Sichuan Changzheng Machine Tool Group Co., Ltd. successfully exported its "Longmen Machining Center" to Boeing, playing a key role in producing the aircraft’s engine blades. This marks the first time a domestic CNC machine tool has secured an order from Boeing and also represents the first successful export of such advanced equipment to the United States. “The machine is specifically designed for Boeing to process complex components on their aircraft,” said Li Zhi, head of the marketing department at Sichuan Changzheng Machine Tool Group. He explained that due to the intricate curved surfaces required for Boeing parts, traditional three-axis machining centers are insufficient. Instead, the five-axis联动 (five-axis linkage) machining provided by Changzheng’s self-developed “GMC Gantry Machining Center” meets these high-precision demands. Currently, only two companies in China are capable of manufacturing such advanced machine tools, and they have reached world-class standards. It wasn’t easy for Sichuan Changzheng to gain Boeing’s attention. According to Li Zhi, the company partnered with Fidia, a globally renowned machine tool manufacturer, last year to sign a comprehensive cooperation agreement covering sales, technology, and market expansion. By leveraging Fidia’s international reputation and showcasing the competitive edge of its GMC Longmen Machining Center, Changzheng was able to earn recognition from industry leaders and ultimately secure the Boeing contract—a major breakthrough for the domestic machinery sector. Furthermore, the machine has been recognized by both the National Development and Reform Commission and the National Defense Science and Technology Commission as a preferred domestic equipment for aerospace and defense industries. Orders from countries including the United States, Germany, and Italy continue to come in, highlighting the growing global confidence in Chinese-made precision machinery.
