Chen Zhengliang, who bravely plays a leading role in military product production and has emerged in the national skills competition, is now a national youth job expert and a CNC operator in the 402 workshop of the Transmission Branch of China Ordnance Jianglu Mechanical and Electrical Group Co., Ltd. He has made great contributions based on his position and has made great achievements in Youth blooms in ordinary posts.
When he first arrived at Jianglu Group in August 2009 at the age of 18, he was just an ignorant teenager. When he saw the company's majestic armored vehicle , he was deeply attracted. His strong desire for knowledge made him secretly determined that he must write an extraordinary chapter of youth in an ordinary position.
The enthusiasm of young people is always the best booster for progress. His thirst for knowledge made him love studying more and more at work. He usually worked hard to learn theoretical knowledge and humbly asked experienced masters for advice when encountering difficulties. By accumulating bit by bit and improving his skills step by step at work, he gradually grew into the company's production backbone and skill master. In a training before participating in the 15th " Revitalization Cup " competition in 2019,
was required to complete the processing of 4 types of parts within 6 hours. Every time he read a drawing, his face became more solemn. The special-shaped parts, tolerances of 0.016 mm, and various high-precision geometric tolerances made his heart sink. The most difficult one is a base that requires turning two planes on the outer circle, and the parallelism requirement is only 0.02 mm. Having never come into contact with this type of parts, he couldn't help but frown. He suddenly had an idea while thinking hard, and used copper pads on the four claws to correct and clamp. After he worked hard to install the product, the instructor suddenly told him that 6 hours had passed. Looking at the backs of other students walking towards the cafeteria, a sense of frustration gradually filled his heart, but his unwillingness to admit defeat drove him to work again. When he picked up the measuring tool with his sore and slightly trembling hands and saw the qualified size displayed on the measuring tool, the joy of success burst out from his heart instantly, accompanied by a strong sense of hunger. , it is already 12 o'clock in the evening.
Experienced masters say that the processing of slender shaft parts for a certain amphibious equipment is too difficult and cannot guarantee the dimensional accuracy and geometric tolerances, so they are all discouraged. He took the initiative and took on this "hot potato" resolutely. The surface roughness of 0.4 and the cylindricity and requirements of 0.01 mm are undoubtedly a new challenge for him. After many unsuccessful attempts, he read through a variety of information, combined with his previous experience in processing long-axis parts, and simulated processing through drawing software. He sat for most of the day. Every time his colleagues urged him to go to dinner, but after he agreed, he It's always too late. Nothing is unachievable. After constant thinking and trying, he finally cracked this "hard nut" by making his own machining tools, ensuring the smooth completion of the company's production tasks.
No pain, no gain. He won the third place in the lathe group in the China Ordnance Industry Group 15th "Revitalization Cup" selection competition. In October 2019, he represented the Ordnance Group in the national finals and won the 10th place in the lathe group; October 2021 , participated in the first Xiangtan vocational skills competition and won the third prize of CNC lathe.
Although it is hard work to search for thousands of pounds, you will only get gold after blowing all the sand. He has won the company's "Competition Pioneer", "Outstanding Youth" and "Job Star" awards many times. In July 2020, he won the title of "National Youth Professional Expert". He took solid steps, used his youth and sweat to work silently in his ordinary position, dedicated himself to realizing the best value of his youth. (Correspondents Wei Zhe and Zhang Dengke)
