"Shaanxi Coal Craftsman" Wang Jianbin: a Tiny Contest

     “Machining each workpiece，We are all with 0..The error of 01 mm is stronger.。”Just obtained“Shaanxi coal craftsmen”Wang Jianbin, senior CNC technician in the machining workshop of Shaanxi Construction Machinery Co., Ltd., said earnestly.。Since joining the work，He worked as a fitter successively.、Boring Machine、CNC drilling work，Always uphold“Quality is in my heart，Quality is in my hands.”The original aspiration and responsibility，Constant pursuit，Keep improving，Make extraordinary contributions in ordinary posts。2002，Wang Jianbin was assigned to work in the machining center of the company's machining workshop.，Become an ordinary machining center operator。Wang Jianbin keeps learning.，He used his spare time to read a lot about the operation of CNC machine tools.、Programming、Books on principles, etc.，Teach yourselfsolidworks、FeatureCAM、hyperMILL、MastercamAnd other three-dimensional designs.、NC programming software，Improve the processing level of CNC equipment，Precipitate one's own theoretical accomplishment，Constantly verified in practice、Accumulate，Gradually grow into an independent technical expert in the machining workshop.。Wang Jianbin's work is full of challenges，He faces complex mechanical structures every day.、Cumbersome program code and changing market demand。As the company has more and more product categories,，Part construction is more complex，He also put forward higher requirements for himself.。He often tells himself.：“Be not afraid of hardship，Second, not afraid of tiredness，Industry is skilled in diligence.，Waste in play。”By studying hard.，Constantly“Grinding” Oneself ，His programming ability and problem-solving ability have reached a qualitative leap.。One time，The construction site fed back that the Paver produced by the company appeared sticky material and color difference during the construction process.。He immediately led the team to review all the components of the screed tamping system of the Paver one by one.，Finally, it is found that the flatness of the bottom surface of the impact tool rest is out of tolerance.。The impact knife rest is the end system of the tamping and leveling system of the Paver.，It is also the core mechanism to ensure the flatness and compactness of the whole paver when laying asphalt pavement.。Because the impact tool rest is long and wide,、Length-thickness ratio up to 16-Near cuboid workpiece with 25 times ratio，The stiffness is low。During NC machining，If the selection of cutting parameters is unreasonable,，It is easy to produce machining deformation under the action of cutting force.，But also cause flutter phenomenon.，It will seriously affect the surface quality and processing accuracy of products.，And even cause scrap。He was with the team.，Make a careful study of this situation。After repeated discussions，Test，Finally, the processing method to ensure the flatness of the bottom surface of the impact tool rest is found。Verified，The desired results have been achieved.，After being put into use，The problem was successfully solved.，Uarantee that product quality of the company。CNC Machining Center“Hold hands”More than twenty years，Wang Jianbin became everyone's mouth.“CNC master”。But he was not satisfied.，Constantly facing new challenges，Constantly overcome difficulties，Enjoying the sense of accomplishment of solving problems again and again.。When programming the NC machining equipment before machining，He always wondered if he could make programming more reasonable.、 Science 、Quick；Is clamping and positioning safer?、Reliable、Valid。Encounter processing of new products，He regarded it as a challenge and test of his technical ability.，Strive for the shortest time and the best processing methods to complete the task.。Paver screed track support he was involved in、Left and right rotating arms of stable accompanying machine、Design and manufacture of tooling for milling rotor and other parts，He optimized the design many times.，And the manufactured tooling is simple to clamp.，And that position is reliable，Easy to use。Over the years，He solved a lot of difficult problems in his work.，Obtain the company many timesQCAchievement award for tackling key problems，It has contributed to the successful completion of the company's production tasks in the workshop.，It has been fully recognized by the company's leaders and employees.。He has won the bronze prize of the first Western CNC Machining Creative Competition in 2013.、2013-2014 Shaanxi Coal Group staff science and technology innovation achievement second prize、2015 Bronze Award for Outstanding Scientific and Technological Innovation Achievements and Technological Improvement of Shaanxi Employees、2015 Shaanxi Construction Machinery Co., Ltd.“Four excellent”Communists、First Heavy Equipment Group in 2018“Reloading craftsman”、2018 Shaanxi Construction Machinery Co., Ltd“Model worker”And many other honors。        Wang Jianbin knows very well，The progress of technology is inseparable from everyone's hard work.，He always said：“No matter how capable a person is,，I can't knock down a few hills.”。He put his own.“Unique skill”Unreservedly imparted to the disciples，He shared his theoretical knowledge and work notes with his apprentices for decades.，From the field process to the specific operation，Explain and teach by hand。At present, two apprentices have become senior technicians，And on behalf of the company to participate in a number of skills competitions in the province，Achieve excellent results。       Wang Jianbin said：“Although engaged in numerical control work for 22 years.，But the longer you do it,，The more I feel the knowledge is very deep.。I will continue to study hard.，Strive to solve the company's numerical control process problems more.。”（Ma
