Zhu Maohua showed good efficiency, and only a few days later, the processing technology of the turboshaft C engine flame cylinder of Tianfeng Technology Company was completed, and it was sent to Li Tianfeng's desk for review, and Yang Xianfeng called.

After receiving Yang Xianfeng's call, Li Tianfeng smiled happily, and after the two chatted a few words on the phone, Li Tianfeng drove to Factory E in person, and in Yang Xianfeng's office, the two talked in detail for one or two hours.

Li Tianfeng gained a lot from this trip to E factory, and reached a lot of agreements with Yang Xianfeng, including dozens of parts in the last list, which started from rough machining, rough machining, semi-finishing, finishing, and finally finished parts, all of which were processed by Tianfeng Technology Company.

Of course, these parts are very difficult to process, and the processing cost makes Li Tianfeng feel very satisfied, and it should be a batch of highly profitable parts.

Using this batch of parts, practicing hands, and cultivating his own talent team, especially his own technical team and front-line technical worker team, this is Li Tianfeng's main purpose.

……

Approaching the Lunar New Year, there are a few days before the Lunar New Year, and when the company officially closes for the holiday, Li Tianfeng, Sun Kang and his entourage will definitely go back to their hometown for the New Year, this year should be a lively Lunar New Year, Li Tianfeng is already preparing for the New Year.

Tianfeng Technology Company is still busy, the year-end rewards of employees have been issued, although many employees have not been in Tianfeng Technology Company for a few months, but Li Tianfeng is still happy to give everyone an extra two months of salary as a year-end reward.

The year-end bonus for grass-roots managers and front-line workers is to pay two more months' salary, while the year-end bonus for all kinds of supervisors, directors and managers is very considerable.

Li Tianfeng's boldness, everyone is very happy, employees see Li Tianfeng, many will take the initiative, warm, polite greeting, you can see that everyone loves and respects Li Tianfeng.

Of course, the six blanks of the turboshaft C engine flame cylinder have begun to be processed, and the newly prepared process regulations for Li Tianfeng to personally check have been issued, and the rough turning is being carried out in accordance with the new process regulations.

"Lao Liu, this blank is really bulky."

"Yes, it's still a superalloy, and a person can't move it, so he has to use a crane to lift it before he can load it on the lathe."

The density of superalloy is slightly larger than that of ordinary steel, and the flame blank of superalloy is a little heavier.

Master Liu, who operates the Dalian CNC machine tool, is processing parts, is doing initial rough machining, and has already processed several pieces of flame cylinders, which are being placed on the ground.

Rough machining of parts, large amount of cutting, cutting block, force is also large, often rough machining CNC machine tools are generally strong, the precision is not very high, the price is relatively cheap CNC machine tools, the CNC machine tools in the first workshop, Dalian, Shenyang CNC lathes are relatively cheap, undertake the rough machining task.

The blank is very bulky, the amount of material cutting is very large, and the body of Master Liu's CNC lathe is full of metal chips of high-temperature alloys, which are cut from the blank parts.

"Lao Liu, I heard that this part is very difficult to process, and I don't think it's good? You process it very smoothly, and you have already processed several pieces in one go. ”

A middle-aged bearded middle-aged car master next to him was chatting with Master Liu while he was free.

Master Liu said: "I also heard that this part is very difficult to process, however, I think the difficulty should be in the finishing, the part is very strong now, to the back, the parts are getting thinner and thinner, I heard that the processing deformation is very bad, and the parts are often scrapped." ”

Both of them are experienced masters who do several cars, and they are very aware of the consequences of the deformation of parts processing, and they can't help but be slightly worried.

"Lao Liu, what did you say the boss did from Factory E to get this hard bone, isn't this looking for his own trouble, what if something happens?" The bearded man said worriedly.

"Lao Zhang, what are you worried about, you see that the newly compiled process regulations are not, the audit signature is signed by the boss himself, and the boss's technical level, you haven't heard of it."

The bearded Lao Zhang has not been in Tianfeng Technology Company for a long time, but he has heard of Li Tianfeng's technical level, and many workers admire Li Tianfeng's technical level very much, and the bearded man often thinks that his top boss has such a powerful technological level.

However, the bearded man still said: "Lao Liu, this qiē is hard to say, I heard that in Factory E, a large group of technical experts have not solved the problem of processing deformation of this part, the boss is really so powerful." “

Master Liu smiled and said: "It's a mule or a horse, just pull it out and walk it, I have confidence in the boss." ”

After these processes, the parts are greatly "slimmed", and they have begun to take shape, and the appearance of the flame cylinder can be seen, and the finished parts are about one kilogram, and the wall thickness is 0.8 mm, which is very light. But now the wall thickness is still seven or eight millimeters, and the weight is about one or twenty kilograms.

A high-precision CNC machine tool imported from Germany, an experienced counting car master is making preparations, preparing to process the first finishing counting process of the flame cylinder.

Such a key part, the processing difficulty is so great, the No. 1 workshop in the personnel arrangement, machine tool selection has been fully considered. Zhou Shiyun used to be an old lathe master in the precision machining center of E factory, and he used to process the finishing process of the turboshaft C engine flame cylinder.

Germany imported several cars, millions of CNC lathes, the quality and machining accuracy of the machine tool are leveraged, just suitable for the finishing of parts like the flame tube.

After a series of preparations before processing, Zhou Shiyun began to clamp the first part, while installing the parts, Zhou Shiyun secretly rejoiced that his choice was so wise, leaving Factory E and joining Tianfeng Technology Company.

As a technician, the salary has risen a lot, and the working environment here seems to be better than the precision machining center in Factory E.

Take a look at the machine tools and equipment here, especially the CNC lathe imported from Germany, even if it is placed in the major aviation enterprises in the country, such a machine tool is also first-class, and he is responsible for operating this CNC lathe imported from Germany.

The quality of the equipment is good, and the processing is very smooth, especially for masters like Zhou Shiyun, the requirements for machine tools and equipment are more strict and more exquisite. In the past, when he was in Factory E, the machine tool operated by Zhou Shiyun was a domestic CNC machine tool.

At that time, even if it was such a domestic CNC machine tool, every time he got off work, Zhou Shiyun wiped and cleaned his CNC machine tool cleanly, and now in Tianfengfeng Technology Company, Zhou Shiyun is even more precious to treat this CNC machine tool imported from Germany.

After a series of preparatory work, a series of work such as loading the parts to be processed, aligning, tool alignment, and simulating running procedures, Zhou Shiyun was meticulous, and the good habit of processing aviation products for many years had obviously been developed long ago.

Press the start button of the machine tool, the program starts to run, the machine tool starts to work, and a slight and steady beep comes from the machine tool, and Zhou Shiyun knows that the processing is normal.

The entrance to the No. 1 workshop.

Li Tianfeng was talking about something while walking with a few people, as if he was introducing the basic situation of the No. 1 workshop to the visitors.

Li Tianfeng led several people from the E factory, headed by Liu Qingshan, deputy chief engineer of the E factory, an old expert of the E factory, Chen Dong, a military representative, and Cheng Gang, the technical director of the precision machining center of the E factory.

As soon as he entered the spacious and tidy No. 1 workshop, Cheng Gang, who came here for the first time, was amazed, "Mr. Li, your factory building is not bad compared to our precision machining center!" ”

Chen Dong, the military representative next to him, also said: "Yes, if you don't come and see it in person, I really can't imagine that you have established such a high-standard workshop, and our parts are processed here, I can rest assured!" ”

Chen Dong is the representative of the army, responsible for the supervision of the machining process of aviation parts in the precision machining center of the E factory, at present, the rough machining and semi-finishing of many parts are placed in Tianfeng Technology Processing, as the supervision of the military generation, Chen Dong has long wanted to come and take a look.

Looking at it now, seeing such a good environment, Chen Dong's expression was very good, and a little joy appeared on his face, coupled with the good personal relationship with Li Tianfeng, Chen Dong was greatly relieved.

Liu Qingshan has been to the No. 1 workshop, and this time he entered the No. 1 workshop of Tianfeng Technology again, and Liu Qingshan still had an amazing feeling.

The group obviously came to see the turboshaft C engine flame barrel processing, Li Tianfeng took everyone and walked straight to Zhou Shiyun's German CNC machine tool.

Cheng Gang's eyes were sharp, and he saw Zhou Shiyun who was processing parts at a glance, and couldn't help but say: "Good guy, Master Zhou, it turns out that you jumped to Tianfeng Technology Company." ”

Zhou Shiyun used to be a number of car technicians in the precision machining center of E factory, and was one of the leaders among the number of car workers.

Zhou Shiyun hurriedly said: "Hello Director Cheng, good leaders!" ”

Li Tianfeng nodded, and then introduced to Liu Qingshan and the others: "Mr. Liu, we have started the first finishing process of the flame tube. ”

"It's so fast, it's only a few days to enter the first finishing process, it's okay." Liu Qingshan said happily.

At the beginning, the turboshaft C flame cylinder has been bumpy in the processing of factory E, and the processing cycle is very long, even if it is rough machining, semi-finishing often has processing quality problems. I didn't expect it to be so smooth now in Tianfeng Technology Company.

"Mr. Liu, the previous rough machining and semi-finishing processes are relatively smooth, and the real test should be in finishing, such as the next finishing process." Li Tianfeng introduced.

Liu Qingshan nodded, yes, the real test is in the finishing process, because the finishing process is very demanding, many size requirements are within a few wires, and with the processing progress, the parts will become thinner and thinner, the rigidity will be worse and worse, with the emergence of processing deformation, whether the parts processing can be qualified, this has to play a big question mark.

Liu Qingshan obviously did not have full confidence in Tianfeng Technology Company in his heart, and he also put a big question mark in his heart, in Liu Qingshan's heart, he was ready for processing failure.

Tang Jianyì, who accompanied him, is a technical expert of the E factory, especially specializing in machining, Tang Jianyì is wearing reading glasses, is holding the processing technology card of this fine turning process, and is looking at it carefully and very seriously.

"The processing card of this process specification is very detailed, clear and clear, and the operability is very strong, and in terms of quality, it is absolutely top-notch." Tang Jian thought so in his heart, and at the same time, his brows gradually furrowed.

"How can it be processed like this, this is going to be a big problem." Tang Jian thought to himself.

Cheng Gang next to him happened to come over, curiously looking at the processing technology card in Tang Jianyì's hand, seeing such a detailed and clear processing process card, Cheng Gang was about to admire, suddenly, Cheng Gang saw Tang Jianyi with a frown.

So, Cheng Gang couldn't help but ask in a low voice, "Expert Tang, what's wrong?" Any questions? ”

Tang Jianyì slammed the processing technology on the work table, and said loudly: "This processing can't be done like this, who compiled the process regulations, this is going to be a problem." ”

The movement was so loud and the tone was so high, all of a sudden, Liu Qingshan and the others all looked over one after another, thinking in their hearts, what's going on?
