“Erzi，Work overtime today to finish these 10 bearing blocks.，The assembly line is in a hurry.。”“Erzi，Help me to see how to do this new job well and quickly.。”Speaking of“Erzi”，The workers of Hebei Xuangong Hydraulic Branch all know，He is Shi Yajun, a senior technician of the Communist Party.。As the second child in the family，Everyone calls him affectionately.“Erzi”。Since he joined the factory in 1996,，Start with an engine lathe，Constantly explore new skills of general car，Through the study of professional books、Online technical exchanges and other channels.，Learn and summarize advanced processing skills，Self-study and master programming method，Reasonable selection and use of cutting tools，Grow up to be an excellent CNC lathe operator，Become the production backbone of the branch factory，Be down-to-earth and work in obscurity on the post。

At work，Shi Yajun never gives up in his work.，He operates alternately on CNC lathes and ordinary lathes.，The labor efficiency is greatly improved.，Whether it is a batch of parts or a temporary one.、Two-piece processing task，He never made any demands.，Always do a good job in silence.。He put forward rationalization proposals and quality improvement many times in the process of processing.，In the tooling、Cutting tool、Production efficiency and so on have their own innovative methods.，Ffectively improve that processing efficiency、Processing quality，And that proces cost is reduced.。He pays attention to observation in the processing of conventional products.，Work hard and skillfully。0AThe tooling 011296 of 21005 bearing seat can not guarantee the processing schedule in the actual processing and use process.，Shi Yajun studied, analyzed and experimented.，Improve the tooling，The tooling is debugged，After designing and processing a new pull rod, ensure the normal use of the tooling。The improved tooling ensures the machining accuracy of parts.，Comply with the drawing requirements，Ensure the quality of parts。This practice，Not only the production cost is reduced,，It also increases the production efficiency by nearly three times.。SD7 Bulldozer 0T42024 coupling plate，The part structure is a thin-walled part.，Extremely high requirements for machining accuracy，In the process of clamping, it is easy to deform and cause out-of-tolerance.。He gives full play to his subjective initiative and relies on years of processing experience.，A four-jaw Chuck is adopted for clamping, a rough turning process is carried out first, and then the work is not unloaded.，Adjust the clamping force of four jaws one by one，And then finish turning is carried out to ensure that the deformation is controlled at 0..05mmWithin，Ensure the design requirements and performance of the part。People asked him what tricks he had to adjust his four paws.，He said with a smile.“Nothing else，Only your hands are familiar！”His years of silent perseverance have made him indescribable.“Feel”。

It is difficult to cut in production.、Workpiece with complex shape and different shapes，Production dispatchers will first think of Shi Yajun.，Jobs that no one else can take.，He made full use of the professional and technical knowledge he had learned and the practical experience he had accumulated over the years.，The processing of various difficult-to-cut and complex special-shaped workpieces is solved.。He carried two pamphlets in his pocket.《Machining parameters》《Manual of standard screw threads》，The paper covered with oil stains and wrinkles is a proof of his continuous improvement.。In the company's new product powder loosening machine.、Smart toilet、In the process of developing new products such as amphibious vehicles and expanding social business，He carefully studied the technical requirements of each part.，Rough machining is done on an engine lathe.，Finish turning process in CNC lathe dry，The utilization rate of the equipment is improved，But also ensure that processing quality of the part.，By optimizing the clamping method and sharpening the tool，Reasonable selection and use of cutting tools，And that proces efficiency is improved.，And that production schedule is ensure to be finished on time.。Machining of Northern Heavy Industry Parts Support，His ingenious self-made simple clamping tooling is evenly distributed in 12 holes.，Adopt four-claw fine adjustment，Not only ensure the machining accuracy，Meanwhile, the processing efficiency is greatly improved.。

As a Communist Party member.，Love and dedication、Keep your nose to the grindstone、Bear heavy burdens bravely、Be willing to give，It's his usual working attitude.。Urgent work、Difficult to live、Heavy work is always rushed to do.，Come early and leave late every day.。In order to seize the task and ensure the progress.，Complete monthly matching hedges，It is common to work overtime，He is anxious to give birth.，Give up rest time on Saturdays, Sundays and holidays，Complete processing tasks with quality and quantity guaranteed。Types and quantities of tasks completed by Shi Yajun every month，He is always at the top of fame and fortune in the branch factory.。

Orders for the company's bulldozers suddenly increased in the second half of last year.，At this time, his mother was in hospital because of overwork.，He is busy taking care of his mother in the hospital during the day.，Busy with production tasks in the workshop at night，The leader of the branch factory advised him to rest for a few days if he couldn't stand it.，He said“ Don't worry ，I can handle it.”。Shi Yajun silently shouldered two ends.，A small family and a big factory are very important in his heart.。

On the eve of the Spring Festival this year，Everyone else is getting ready for the New Year.，Shi Yajun received a temporary production task.，After the design improvement of the processing bulldozer, 15 connecting shafts are used for the assembly of the whole machine for export.，Time is tight and the task is heavy.，Because it is the first processing.，Digestion of drawings，Programming design、It takes a lot of time to make technical preparations such as tool selection.，By the time all the 15 shafts were finished, it was already more than 10 o'clock in the evening.。For him，It is common to work overtime，But he had no complaints.，Stick to and dedicate silently in the post。

The difference between a person who strives and an ordinary person is that he has a great goal in his heart and keeps striving towards it.。He has worked tirelessly for nearly thirty years.，Constantly pursue，Love and dedication，Love the factory like home，The job is ordinary.，But he strives to make more contributions to the enterprise.。His brainstorming and development of the company's new product parts continue to make technological breakthroughs.，Become a piece of fine works，Highlight the craftsman spirit of ordinary operators of Xuangong。
