Hong Jiaguang： From Rural Baby to Chief Expert

CCTV News:Born in poverty, he grew from a fledgling technical school graduate to the chief senior technician of AVIC, and has six national inventions and new utility patents. He said: "It’s not only when you have a dream that you persist, but when you persist, you make your dream clearer." He is Hong Jiaguang, a senior technician of AVIC Shenyang Liming Aeroengine Co., Ltd.

Turn the bus into a "mobile library"

In 1978, Hong Jiaguang was born in a rural family in Shenyang. Because the family is poor, the sisters have been self-reliant since childhood and helped the family with farm work. In summer, when other people’s children are eating popsicles and running around the street, Hong Jiaguang is helping his mother push the garbage, smelling the disgusting stench every day; In winter, when other children sit around the heater and do their homework, he can only accompany his mother to push the cold garbage truck.

In order to earn money to support his family as soon as possible, Hong Jiaguang chose a technical school after graduating from junior high school. From Hong Jiaguang’s home to the technical school, you need to take the train first and then transfer to the bus. It takes more than 4 hours to get back and forth by bus. While others were sleeping in the car, Hong Jiaguang, who cherished time, chose to read books and turned the shuttle bus into his "mobile library". In three years, he taught himself four technical books on the bus. In 1999, he was assigned to avic Shenyang liming aero-engine co., ltd with the first graduation.

When he first entered the factory, Hong Jiaguang’s monthly salary was only 180 yuan, and he ate a bowl of pulled noodles from 2 yuan every day to satisfy his hunger. At this time, he has no goal and talks about hope. But he didn’t give up his efforts. He used his spare time to cram his professional knowledge and arm his technical level. In the eyes of workers, Hong Jiaguang is a "freak". He shuttles in the machine tool workshop every day, even thinking about how to improve his "craft work" when eating.

"Desperate Saburo" learns from the teacher

In order to master more profound technology, Hong Jiaguang decided to learn from Meng Xianxin, a national model worker. But at that time, Meng Xianxin neither knew Hong Jiaguang nor was in the same workshop with him. How to learn from the teacher became a difficult problem. Hong Jiaguang used the most stupid method — — Die grinding hard foam. For several days in a row, he went to Master Meng and took the initiative to be his little assistant. He found that when cutting internal threads, the average worker can only work at 600 revolutions per minute, and when it is fast, he will directly punch the knife, but Master Meng can work at 1200 revolutions per minute without reversing the knife. "I was really shocked at that time, and I strengthened my belief in learning from teachers," Hong Jiaguang said.

In the following days, Hong Jiaguang paid equal attention to practice and thinking, and kept learning in his work, accumulating in his study, and his skills advanced by leaps and bounds. At that time, it was not easy for others to complete 4000 working hours a year, and Hong Jiaguang completed more than 7000 working hours a year.

In 2000, the company’s production tasks were extremely heavy. Hong Jiaguang simply moved his luggage to the factory and stayed there for more than a month. Due to overwork and exhaustion, the workpiece hurt his left hand during handling. In order not to affect the progress of the work, Hong Jiaguang didn’t go to the hospital and endured the pain and continued to work. Until the evening, he rolled in bed in pain, and his lover dragged him to the hospital, and he was diagnosed with severe comminuted fracture. The doctor asked him to rest at home for 2 months. However, thinking of the workpieces piled up on the workbench, Hong Jiaguang finally ignored his lover’s dissuasion and returned to work after 3 days’ rest. His left hand was bandaged and his right hand operated the machine tool. He worked for two months. Since then, everyone has nicknamed Hong Jiaguang "Desperate Saburo".

Hong Jiaguang said: "We young people love to talk about fairness. I think that if you want to make faster progress and gain more than others, you have to pay more than others. This is fairness. If you are as comfortable as others and live slowly, you will be better than others. This is an unfair dream. "

Let China Power be famous for its thick soil and liaojiang.

Near the Spring Festival in 2002, the company issued an urgent task — — Diamond roller, a correction tool for machining the core blade of a key engine. Because it is a correction tool for core blades, it requires extremely high accuracy, and all dimensional tolerances are required to be within 0.003 mm, which is equivalent to 1/20 of human hair. If one dimension is out of tolerance, the whole part will be scrapped, and if the diamond roller is ultimately unqualified, thousands of blades will be scrapped.

At that time, only Master Liu mastered the technology in the company, but at that time Master Liu happened to be ill and hospitalized. Time waits for no one, and Hong Jiaguang volunteered to undertake the task with the strength of "newborn calves are not afraid of tigers".

At first, Hong Jiaguang processed the parts according to Master Liu’s method. Unexpectedly, after more than ten hours of hard work, none of the products were qualified! That night, Hong Jiaguang stayed up all night. After that, he tried to improve the processing method and worked continuously for more than 14 hours every day. When he was hungry, he took two bites of the pie in his pocket. In this way, the technology that others seem to take several years to master was broken in a short period of 10 days.

Since then, he has successively solved the machining problem of diamond roller, a new generation of key engine blade grinding tools in many countries, rewritten the history that the company’s diamond roller can’t be machined, and created a great achievement that surprised his peers. The application of this technology has created an output value of more than 92 million yuan for the company, and has been successfully authorized as a national invention patent. This important breakthrough was written "Made in China", leaving Hong Jiaguang’s name.

Over the past ten years, Hong Jiaguang has completed more than 100 technological innovations and solved more than 300 technical problems.

"Someone asked me, are you so hard, so hard? My feeling is that the strugglers are hard in the eyes of onlookers, but in fact, their spiritual world is rich and full of happiness because of struggle. " Hong Jiaguang said, "I may not make such great contributions as outstanding scientists like Wu Zhonghua, Shi Changxu and Wu Daguan, but I am willing to be a stone in the aero-engine industry, send China’s heart to the sky, and make China Power famous!"
