At 9:22 on June 17, 2021, Beijing time, the Long March 2 F Yao 12 carrier rocket carrying the Shenzhou 12 manned spacecraft was ignited and launched at the Jiuquan Satellite Launch Center. Since then, the Shenzhou 12 manned spacecraft successfully separated from the rocket and entered the scheduled orbit. The three astronauts Nie Haisheng, Liu Boming, and Tang Hongbo were successfully sent into space. The flight crew was in good condition and the launch was a complete success.
¡¡¡¡ On June 17, the Long March 2 F Yao 12 carrier rocket carrying the Shenzhou 12 manned spacecraft was ignited into space at the Jiuquan Satellite Launch Center
¡¡¡¡ This is the 19th mission since the establishment and implementation of my country's manned space project, and it is also the first manned mission in the space station stage. After the spacecraft enters orbit, it will carry out autonomous and rapid rendezvous and docking with the core cabin of Tianhe in accordance with the predetermined procedure. During the flight of the combined body, the astronauts will be stationed in the space and core module to complete a three-month stay in orbit.

The successful launch of ¡¡¡¡ Shenzhou XII not only represents a new level of Chinese aerospace technology, but also has a strong backing made in China. The abrasives industry is an industrial tooth, and aerospace is one of the important areas of high-end grinding. The parts of aerospace industry products are characterized by high temperature resistance, high strength, and difficult to process. At the same time, there are many alloy materials and composite materials, many complex structural parts, and high technological requirements, which puts forward higher requirements for their abrasive products. In order to promote the development of aerospace industry, in recent years, many domestic grinding enterprises have gradually stepped into the field of aerospace users, realized import substitution to a certain extent, and made contributions to the national cause.
¡¡¡¡As at present, more and more advanced grinding tools and technologies such as PCD and PCBN material cutting tools and powerful grinding are used in the aviation field. Such as the PCD tool for machining engine pistons, and the electroplated CBN grinding wheel for machining the narrow and deep grooves at the roots of aero-engine turbine blades. The vitrified bond CBN grinding wheel is also used in the processing of aero engines. At the same time, in the polishing of some parts of the spacecraft, the products of high-end coating companies have also played an important role.
Although my country¡¯s abrasives industry has a history of decades of development, it still has a long way to go in the high-end manufacturing field. It is very important to increase investment in science and technology, increase the technological content of products, and adhere to the development direction of high-end products. , Without today¡¯s investment, we would not be ahead of us tomorrow. Let us work together to help Chinese manufacturing and contribute to the future high-end manufacturing of abrasives!
