The crankshaft lathe is the final process of the overall machining of the crankshaft. There are only dozens of such machine tools in the world, and the requirements for the operator's ability are very strict. The operator must not only learn the programming of the system, but also master the equipment operation and maintenance information. For Zhao Yumin, these harsh requirements are the driving force for him to move forward and accompany him all the way.

Zhao Yumin, male, member of the Communist Party of China, born in 1985, graduated from Dalian Vocational and Technical College in January 2006, and joined Dalian Heavy Industry in the same year, engaged in the operation of large-scale CNC machine tools. After several years of hard work and research, he has completed the transformation from an apprentice to a master of high-precision equipment, upgraded from a junior worker to a senior technician, and then matured from a single-item senior technician to a double-material senior technician. Now it is Dalian Heavy Industry Huarui crankshaft high-precision equipment crankshaft lathe main machine, undertake many "China's first" crankshaft manufacturing.

Zhao Yumin, CNC lathe worker: undertakes the manufacture of many "China's first" crankshafts

Operate the crankshaft alone

Zhao Yumin takes every opportunity to learn, insists on learning the professional theory of CNC programming and crankshaft manufacturing technology in his spare time, and humbly learns from others to ensure more than 100 processing methods of crankshaft "machining accuracy, shape and position accuracy and surface roughness" in his work. and solutions to complex problems.

In May 2010, with his outstanding work performance and rigorous work attitude, the company leaders transferred him to the post of "German crankshaft integral machining machine tool", which is a high-precision equipment, and is responsible for the overall finishing process of crankshafts. He is a veritable crankshaft manufacturer. The guardian of precision, and participated in the manufacture of the crankshaft company's first crankshaft, the first 90-type crankshaft, China's first Wärtsilä 82T crankshaft, China's first butt-type crankshaft 11S90ME-C, China's first longest full-stroke 6G80 type Crankshaft, manufacture of China's first longest full-stroke single-weight and heaviest 7G80 crankshaft.

Honor is not a reason to stop

With the development of the company, the full range of product models has made Zhao Yumin realize that a strong person is not really strong, but a strong group can truly enhance the company's manufacturing capabilities. Therefore, Zhao Yumin not only pays attention to the improvement of his own ability, but also asks his "apprentices" to think and do more research. With the innovative concept of Crankshaft Company's equipment quota, all his apprentices are assigned to the main engine positions, and they have become the backbone of equipment operation. .

In Zhao Yumin's view, awards and honors are only an affirmation of his own efforts in the past, and do not represent the size of an individual's contribution to the enterprise. He always feels that only by transforming the improvement of personal skills into the improvement of production efficiency is the one with the greatest skills. Value embodiment is the most effective way to reward enterprise training.

Reporter's Testimonials
