To successfully obtain valuable lunar soil, a series of key core technologies such as surface sampling and drilling are essential. Among them, surface sampling refers to using a robotic arm to carry a sampling device to shovel lunar soil or pick up lunar rocks at multiple positions on the lunar surface; Drilling is the process of using a drill rod to drill into the lunar surface at a predetermined depth and collect lunar soil core samples that maintain the "profile sequence". Sampling is more difficult and uncertain.

In drilling sampling, the rotary shaft system of the drilling mechanism independently developed by Luoyang Bearing Research Institute Co., Ltd. (hereinafter referred to as "the shaft research institute"), a subsidiary of the group, plays an important role. As the main transmission mechanism of the drilling mechanism, this equipment can transmit the rotary torque generated by the rotary motor to the drilling tool, as well as the impact force generated by the drilling mechanism to the drilling tool, thereby achieving the transmission of rotation and power from the drilling mechanism to the drilling tool. It is equivalent to the "arm" during the sampling process of Chang'e-6 drilling, making it capable of adapting to various complex and harsh working conditions, ensuring stable drilling of the equipment, and making subtle adjustments according to actual conditions to achieve flexible drilling.

During this lunar exploration mission, Chang'e-6 also sent back a series of images taken during landing on the far side of the moon. During this process, products developed by the Axis Research Institute also played an important role. Among them, the high-precision and high vacuum solid lubrication bearings applied to the support mechanism of the Chang'e-6 camera ensure the normal and stable operation of the camera, enabling Chang'e-6 to accurately capture image data; The anti heliocentric bearing component applied to the solar wing sail allows the solar wing sail to rotate flexibly, providing sufficient power for the smooth progress of the Chang'e-6 shooting mission.

In addition, as the sampling location is located on the back of the moon, in order to ensure communication, the Queqiao 2 relay satellite is needed to build a communication bridge. The microwave coaxial switch provided by the Axis Research Institute is equipped with high-precision, highly sensitive, and high vacuum solid lubrication bearings, which enables the Magpie Bridge II to maintain a stable and high-precision attitude and angle at all times, and can accurately transmit received signals to the ground through different frequency bands.

For many years, China National Machinery Corporation has been focusing on building a strategic technological force to support high-level technological self-reliance and self-improvement. The key single machines and multiple bearing products developed have been applied to major aerospace projects such as the Shenzhou series manned spacecraft, Tianwen-1, and China Space Station. In the future, China National Aeronautics and Astronautics Corporation will continue to strengthen key core technology research and development, face difficulties and move forward courageously, and use high-quality independent innovative products and technical services to help China's aerospace industry develop to a new level
