Precision machiningTo ensure that the Chang'e-3 manufactures zero errors
December 14, 2013 was a very special day for our country. Our National Space Administration launched the Chang'e-3 "Moon Landing Probe" from the sky and successfully achieved a soft landing on the moon's surface. This is also the third country to achieve this great achievement. This makes each of us more proud of Chinese people. So what we need to know is that a satellite has to go up to the sky, and the launch of the rocket, whether it is a rocket, a satellite, or a landing probe, usually requires very precise parts to assemble. Then these parts need precision machining technology which is very professional to complete. You must know that there can be no errors in the middle, and the parts must be very accurate. In fact, many problems were encountered in the manufacture of Chang'e-3. At that time, the task of Chang'e-3 was carried out by the workshop 25 of 7103 Factory of the Sixth Aerospace Academy and a group of this excellent team. With their tenacity, they completed almost Possible tasks. The first headache in front of workshop 25 is how to process the precision parts of the needle valve injector. The needle valve injector is a component that is extremely difficult to process in the new generation of carrier engines, and the flow regulator is the engine. The key valve used for working condition transition and stable system flow. Before this, there was no reference material, no one had done it, and no such high-precision equipment could be processed. In the case of "three nos", the team leader A military warrant was made and a research team was established. After more than a month of hard work, this part was finally completed successfully in their hands. Of course, such Precision parts can be processed, which is also a major breakthrough in the field of Precision machining. Then there is the "temperature and humidity tube" on the Chang'e-3. The precision tolerance of the Precision parts is basically in the micron level. A slight error will make the entire Precision parts scrapped. This is very demanding for the production and processing environment and the operator. harsh. But even so, Comrade Xiao Su, who was responsible for the process, worked hard to finally overcome the difficulties in this regard. There are still many problems like this, and the processing difficulty of Precision parts is also greater than one, but every employee of the 7103 factory just worked hard to solve these problems one by one. So that we can see Chang'e-3 and our five-star red flag on the moon. We would like to thank these people who worked hard on the front lines, and they have pushed the Precision Machining industry in our country into the forefront of the world.
