The ancients said：“See the style in the subtleties，A tiny bit of excellence determines the universe.。”The master has a fight，Win at a fraction of a cent，Everything，See the big from the small。In Zoomlion，“Four essences”、“Four strengths”、“Four wants”、“Four extremes”The concept is engraved in the corporate culture.，Circulation in the philosophy of life、Accumulate in the forward force，Help Zoomlion's continuous innovation and development。

Hunan Zoomlion Axle Co., Ltd.（Hereinafter referred to as Zoomlion Axle）Wu Jiajian, head of the fitter team in the preparation workshop，It is such a person. “Clamp”A consummate master。And file board、Drill bit“Stay together”34 years，To be subtle and refined，Carved with great care，Pursue the ultimate quality，Hone excellent skills。

The blade walks，Show ingenuity between square inches

Since entering the factory in 1988，Wu Jiajian's workbench is in the southeast corner of the vehicle bridge preparation workshop of Zoomlion.，It hasn't been moved for more than 30 years.。

“You want to ask me what is ingenuity?，In fact, I am not very good at expressing myself.。I feel that a simple task should be done as a great cause.，Try your best to be the best you can be.，This is probably ingenuity.。”Wu Jiajian said。

If the major types of work in the Seiko workshop also have schools,，The fitter is probably.“The Condor Hero”General existence，Chipping、File、Sawing、Draw a line、Drilling、Reaming、Tapping and threading、Scraping、Grind、Correction、Bending and riveting，Eighteen kinds of martial arts are complicated and chaotic.，Understand by analogy。

Deep ploughing fitter for many years，Wu Jiajian has his own understanding of his own work.：“Fitter is the most basic metal processing technology in mechanical manufacturing.，Many times there is no proper mechanization.，It can only rely on the craftsmanship of workers to do precision processing.。The main work at ordinary times includes the marking of parts.、Drilling、Mold and fixture manufacturing and assembly debugging，It usually takes at least three years to finish his apprenticeship.。”

Between square inches，The infinite universe；Fingertip reversal，Iron filings are flying。Wu Jiajian shuttles through the complicated workshop.，Hold the precision of the part，Immersed in the exploration of technology。Stick to the three-foot drilling machine，Good Thinking and Diligent Practice Achieve Technical Benchmarking；By virtue of“Fine、Quasi、Steady、Set”，Set a super high pass rate of crane axle parts。

In addition to their own hard work and continuous summary.，Have developed superb skills，Wu Jiajian is also obsessed with the fitter profession.，He has participated in many staff skills competitions and won the first prize.，Honored by Hunan Province“Technical expert”And“National Advanced Individual of Knowledge Workers”，Evaluated“Changde Skills Master Studio”……Fitter Jianghu，There's always been something about“Master Wu”The legend of。

Keep pace with the times，Workaholics are brave to innovate.

As a senior employee of Zoomlion，Wu Jiajian was deeply touched by the changes around him.。“The factory is still the factory.，But I can feel the wonderful change.。Especially after 2008.，This change is more obvious.。”Wu Jiajian said，“The management system is gradually improved.，The cultural atmosphere is stronger，Traditional enterprises are stepping into modern enterprises，It makes people feel confident from the bottom of their hearts.！”

Perhaps it is under the influence of this new atmosphere.，Wu Jiajian often falls into“Workaholic”The pattern of，Unable to extricate oneself。According to statistics，2018 only 1-August，He worked overtime，Output mold、135 pairs of clamps，Production steering knuckle、Take the dish、11300 parts for brakes and other products。

The greater the ability，The greater the responsibility。This is vividly reflected in Wu Jiajian.。“Difficult mold，New and remanufactured work pieces，It's usually done by our group.。Because of these processes，More experience is often needed.。” Wu Jiajian recalled，“For exampleDHigh Precision Technical Difficulties in the Mould Processing of 560 Tube Expansion Bridge，I led the team members to break through together.。”

D560 pipe expansion bridge mold，Belon to a hot working mould.。The workpiece needs to be preheated，And enter a mold for molding，Change shape。“Transition from circle to square，Due to its small size，NC machining is difficult to operate.。” Therefore，File、Scraper、Bench vice，Reamer、Drilling machine、Grinding machine, etc“Eighteen kinds of weapons”Fly up and down、Flames splashed everywhere，Make a pattern，Hand carved，And then sanding、Polishing、Amendment——The workpieces are neatly arranged on the workbench.，Like a work of art，The silver shines far and wide。

Machining of Bridge Fist End of 150t All-Terrain Crane，Previously, it has been processed by boring machine directly.，The efficiency of mass production always fails to break through the bottleneck.。Wu Jiajian devoted himself to the study，Pre-processing is proposed.Ø60mmThe hole，Reuse positioning tool，Reaming from boring machine toØ67mmA new processing scheme.，The production efficiency is greatly improved.。

“No matter how fast CNC machine tools and intelligent processing develop.，The fitter's handicraft is never out of date.。Parts and components restructuring、Small batch customization and assembly、Find it、Leveling，They all need to be adjusted by fitters.，In many cases, automatic processing can not be replaced.。But，It doesn't mean we can do it once and for all.，Keep yourself always.‘Freshness’，Constantly accept and learn new knowledge。‘Jianghu’，It's huge！”Wu Jiajian often shares his experience with young colleagues.，At the same time, he unreservedly imparted his life.“Martial arts”。

As a post-70s generation，Wu Jiajian loves fishing.，Gu Long, Jin Yong and Jianghu Dream are indispensable in daily life.。End of the interview，Wu Jiajian received a notice from the Zoomlion Axle Trade Union.：End of September，A new round of skills competition is coming.。Fitter Wulin，The wind and clouds rise again，Who knows who loses and who wins?？“Just spell it.！”Wu Jiajian said，“Huge rivers and lakes，If you don't try your best.，Who can always laugh proudly?？”Just as Zoomlion has been forging ahead for 30 years，“Just a young classmate，In the prime of life”！Count the romantic figures，Still look at the present！
