The technical room, the comprehensive management room, the quality room, the director's office, and the large and small conference rooms in the precision machining center are all on the second floor, and at this time, there are already a lot of people sitting in the small conference room on the second floor.

Peng Xuehai, director of the precision machining center, sat in the middle with a black face, and all around, the deputy director of production, the deputy director of technology, the director of the technical office, several experts from the engineering and technology department, and several technical backbones were sitting there with a solemn face.

Peng Xuehai's tone was low, but there was a sternness, "Today our precision machining center is a disgrace, and the wheel wheel of the first stage compressor of the turboshaft C engine is messed up in our hands......"

Not long ago, the chairman and general manager of E factory was transferred, the new chairman and general manager has arrived, and the new official has taken office with three fires.

Several directors here also basically think like this, so everyone attaches great importance to this incident, and the pressure is naturally relatively large, just kidding, the turboshaft C engine is a National Day gift model, and the material of the compressor wheel disc is still bought at a great cost from Lao Maozi.

The atmosphere in the conference room was gloomy, and after a long time, Chen Xiangchun, the deputy director of technology, hesitated in his heart, and stopped talking.

Peng Xuehai saw Chen Xiangchun's expression, and Peng Xuehai, the leader in his heart, waved his hand and said, "Director Chen, just say anything directly." ”

"Director Peng, then I'll say it." Chen Xiangchun took a look at everyone, and then said: "Our Li Tianfeng is good, I think this comrade has strong technical ability, especially CNC programming ability, I think he can be called to come over to participate in the meeting." ”

The key process of the first to third stage compressor wheel disc of the turboshaft C engine is the five-coordinate CNC milling processing of the integral blade disc, and the first-stage compressor wheel disc is scrapped in a row on the five-coordinate CNC milling processing, and there are still two blanks left in the first batch of parts.

Seeing Chen Xiangchun say Li Tianfeng's name, most people didn't think so, everyone knew Li Tianfeng, after all, they were all from the same unit, and Li Tianfeng's usual appearance seemed to be pretty good, so everyone's impression was a little deeper.

It's just a little more impressive, everyone doesn't think that Li Tianfeng has a particularly outstanding place in technology, just kidding, Li Tianfeng has been working for three years, and his title is only an assistant engineer, not even an engineer, most of the people here are engineers, senior engineers, and even researcher-level senior engineers, which is not much stronger than Li Tianfeng, and it is very normal for most people to show a disapproving look.

Peng Xuehai's face also sank, and he thought in his heart, this Chen Xiangchun really doesn't know the severity. Seeing Peng Xuehai's expression, Chen Xiangchun said: "Director Peng, don't underestimate Li Tianfeng, the young man's skills are very powerful, I promise." ”

"You promise?" Peng Xuehai looked at Chen Xiangchun with blazing eyes, and his eyes were very powerful.

Facing Peng Xuehai's gaze, Chen Xiangchun nodded and said, "I promise, Li Tianfeng will definitely not let us down." Today, Li Tianfeng's excellent CNC program and almost perfect machining of the 10th stage of the turboprop C engine compressor has almost convinced Chen Xiangchun, the deputy director of technology.

Seeing that Chen Xiangchun was so sure, Peng Xuehai pondered a little and said, "Okay, you go and call Li Tianfeng, I will ask in person." ”

Chen Xiangchun immediately walked out of the conference room, and soon brought Li Tianfeng in, Li Tianfeng entered the conference room, and saw so many people, and many of them were leaders or technical talents, and immediately said loudly and politely: "Hello leaders!" Hello experts! ”

Li Tianfeng's attitude was good, and the young man was neither humble nor arrogant, and he couldn't see a little nervousness, Peng Xuehai nodded with satisfaction, pointed to a position not far away next to him and said, "Xiao Li, you sit down first." ”

Li Tianfeng sat down in the position according to his words, Peng Xuehai gave a look, Chen Xiangchun immediately briefly introduced it clearly, and when he heard the words, Li Tianfeng knew it.

Looking at the two scrapped vortex C first-stage blade disc faulty parts on the table, and carefully looking at the parts diagram hanging in front of them, the entire conference room was quiet, and the eyes of so many people were focused on Li Tianfeng.

There are disdain, there are disdain, there are doubts, there are speculations, there are all kinds of people, no matter which level is higher than Li Tianfeng, and the professional title is also higher than Li Tianfeng, at this time, everyone is looking at Li Tianfeng, waiting for Li Tianfeng's reaction.

After looking at it, Li Tianfeng nodded slightly, and then saw that the conference room was quiet, everyone's eyes were focused on himself, Li Tianfeng couldn't help but smile slightly, in such a situation, so many people focused on themselves, a newcomer with only three years of work experience, it is really rare.

After smiling slightly, Li Tianfeng said: "Director Peng, it is not difficult to process this part, I am sure." ”

"You're sure!" Peng Xuehai's heart was slightly light, seeing that Li Tianfeng's expression did not look like he was lying, Peng Xuehai nodded in his heart, but his expression was still very strict, and he said in a deep voice: "Xiao Li, you must know that the turboshaft C engine is a National Day gift model, and the first-stage compressor blade disc is one of the key parts of the engine. ”

Seeing that Peng Xuehai said so much, Li Tianfeng naturally knew what Peng Xuehai meant, and Li Tianfeng said confidently: "Director Peng, if I am responsible for these two remaining blanks, I will not let you down." ”

Hearing this, Peng Xuehai said loudly: "Okay, okay, I'm in charge of these two blanks, and I'll leave it to you to be responsible, and you can put forward any conditions." ”

Huang Xuewen, deputy director of the Engineering Technology Department who attended the meeting, was the first to stand up and object, and said loudly: "Director Peng, this is not appropriate, I firmly oppose it, how can a person who has only been working for three years be competent, in case of scrapping again, we can't afford to take this responsibility." ”

Huang Xuewen and Peng Xuehai are about the same level, both are deputy director-level cadres of Factory E, if it is usual, Peng Xuehai may give Huang Xuewen some face, but not today.

If the first stage compressor blade disc of the turboshaft C is not machined smoothly within a few days, it will delay the process of the turboshaft C engine for a large extent, you know, the rest of the parts of the turboshaft C engine have been basically machined out of the line, and only some key parts remain, which are also the most difficult hard parts, most of which are in the precision machining center.

The engine assembly workshop of factory E is only waiting for these parts to be cooked, and once these hard parts are processed out of the way, the assembly workshop can be assembled immediately, on the contrary, the assembly workshop can only wait forever, and the turboshaft C engine is a political task, and everyone can't afford to wait, and the day of the National Day military parade will only approach day by day.

At present, everyone doesn't have a good processing plan, so it's better to take a risk if it drags on like this, so Peng Xuehai frowned and said: "Deputy Director Huang, I'll give Xiao Li a try when I make a decision on this matter." ”

Huang Xuewen was extremely unhappy in his heart, but this was another matter of someone's precision machining center, Huang Xuewen glanced at Li Tianfeng fiercely, and said fiercely: "I don't know how thick the sky is, this matter is messed up, you just wait to be expelled." ”

Li Tianfeng was also unhappy for a while, he just wanted to do something to solve this processing problem, he didn't think Huang Xuewen was like this, so Li Tianfeng stiffly pushed back, "Deputy Director Huang, do you have a good processing plan, then you can tell everyone about your plan." ”

"You!" Huang Xuewen was angry in his heart, angry, and speechless for a while, if there was a good processing plan, Huang Xuewen would not sit here and hold a meeting with everyone to discuss.

I didn't think that I was stiffly pushed by Li Tianfeng, and Huang Xuewen, who was so angry, dropped a sentence: "I don't participate in this matter, I'll see how you explain it to the factory if something goes wrong." After speaking, Huang Xuewen left angrily, and when he left, he slammed the door of the conference room and made a loud "clang".

"What a su zhì." Seeing this scene, Peng Xuehai's face sank, and then he waved his hand and said, "The meeting is over!" Xiao Li and Director Chen stayed. ”

When everyone saw Peng Xuehai speak, they immediately dispersed, and soon, the conference room was empty, Peng Xuehai said: "Director Chen, we have no way back this time, Xiao Li, it's up to you this time, if these two parts are also scrapped, my old Peng will resign and go home." ”

Li Tianfeng grinned and said, "Director Peng, you are serious, without further ado, I will start working now." ”

"Okay, just tell me if you need anything." Peng Xuehai said, "Director Chen, you and Xiao Li work together to process these two parts, so that no one will see the jokes of our precision machining center." ”

Li Tianfeng immediately out of the conference room, the first thing is to choose the tools needed for processing, Li Tianfeng went straight to the tool library of the precision machining center, where there are a large number of tools, all kinds of turning tools, milling cutters, drills, etc., there are many types, and there are many alloy tools that are more expensive than the price.

Li Tianfeng selected, the tools required for processing are basically selected, they are the best and most suitable alloy tools, the tools are coated, and the price of each one is naturally not cheap.

As an aero-engine manufacturing enterprise, E factory is involved in high-precision processing, and has cooperative relations with many famous brand tool manufacturers, such as Sandvik, Iscar and other well-known manufacturers.

After selecting several types of tools, there is still a very critical ball nose CNC milling cutter and a special CNC milling cutter, Li Tianfeng knows that he can only design it himself, and then hurry up to manufacture.

If you want to do a good job, you must first sharpen your tools!

Suitable processing tools are indispensable, Li Tianfeng returned to the technical room, although it was night, there were still a lot of technicians in the technical room working overtime.

"Brother Li, you are a good cow, I heard that you even topped the deputy director of the Engineering Technology Department, Huang, amazing, you are simply my idol." Zhang Can was also working overtime, and when he saw Li Tianfeng coming in, he immediately gave a thumbs up.

Li Tianfeng shook his head helplessly, it's really a good thing not to go out, and a bad thing to spread thousands of miles, how long has it been, Zhang Can knows it.

Contradicting Huang Xuewen just now, is it what he wants, that is also a helpless move, if it wasn't for Huang Xuewen being angry with himself just now, he wouldn't have resisted, it seems that Huang Xuewen will definitely find trouble for himself in the future, thinking that Huang Xuewen is a deputy director, Li Tianfeng will have a big head for a while.
