After receiving this drawing, Zeng Qinghai looked seriously, the more he looked at it, the more frightened Zeng Qinghai became, and the more he looked at it, the more excited Zeng Qinghai became, because Zeng Qinghai completely understood this design drawing. ◎ Top Novel, x.

The design is so ingenious that it's incredible!

"Boss, this is designed by you, it is so admirable, once this self-locking nut is produced, it will have broad market prospects."

What is the price of imported self-locking nuts, Zeng Qinghai still knows more clearly, a small self-locking nut costs hundreds of pieces, this kind of self-locking nut on the drawing is more ingenious than the kind of self-locking nut imported now, and the quality and reliability will definitely be better.

Such a nut, if it is really manufactured, even if it is sold at half the price of imported self-locking nuts, it is also a huge market, Zeng Qinghai is excited!

Seeing Zeng Qinghai so excited, Li Tianfeng said happily: "Qinghai, I have compiled the general process framework of this bell self-locking nut, you can use it to improve it, in addition, apply for a patent quickly, and the design drawings must be kept strictly confidential." ”

Zeng Qinghai naturally knew the importance of this, and nodded hurriedly.

After explaining some things to Zeng Qinghai, watching Zeng Qinghai happily leave his office with the design drawings, Li Tianfeng smiled happily, and then thought of going to the No. 2 workshop to take a look, some Halli-Burton company parts are being processed in the No. 2 workshop.

According to the plan, the No. 1 processing workshop mainly processes aero engine wheel discs and shaft parts.

The second workshop mainly produces all kinds of casing parts.

Workshop 3 will mainly produce various types of blades for aero engines.

Workshop 4 will mainly produce various types of structural parts.

The No. 5 workshop mainly produces all kinds of sheet metal parts and welded parts.

The No. 6 workshop mainly produces all kinds of fasteners and all kinds of small parts.

The cold machining workshop is planned to be six, in addition to the hot processing workshop, the No. 7 workshop for casting, and the No. 8 workshop for surface treatment. The ninth workshop based on forging and so on.

Each workshop has a clear product positioning, which is equivalent to specialized production, a workshop specializes in the production of the same type of parts, which is of great help to technical management and technology improvement.

Workshops No. 1 and No. 2 have been fully put into use. Among them, the No. 1 workshop has reached full capacity, all kinds of personnel, organizational structure, machine tools and equipment have been improved, the No. 2 workshop is improving, the workshop has nearly 200 employees, and all kinds of machine tools and equipment have reached more than 100 units.

Workshops No. 3 and No. 4 started construction almost simultaneously last year, and currently. It is nearing completion and will be ready for use in about a month.

The No. 5 and No. 6 workshops started construction at the end of last year and have been under construction for several months, and the plant has been capped and is expected to be put into use in two or three months.

The seventh, eighth and ninth workshops started construction at the beginning of this year, and the progress of the project has been halfway through, in addition, Tianfeng Technology Company still has a large area of vacant land. The planned assembly plant has also started construction last month, which is expected. The construction of this large workshop will be completed in the second half of this year.

As for the test workshop, because of the extremely high technical content and special requirements for the location, Li Tianfeng is stepping up the site selection.

The technical content of the test workshop is not comparable to that of the general workshop, just take the test bench as an example. Not to mention the high-altitude platform, that thing is too tall, Li Tianfeng didn't think about it for the time being, that is a matter of the future, the construction of the test bench. Technology-intensive, capital-intensive, and likely to take a long time.

Such a workshop, absolutely impossible to build in the high-tech development zone, engine test, the noise is very large, once tested, the surrounding enterprises must not be able to stand it, site selection must consider many factors, such as traffic, environment, etc.

After Li Tianfeng watched Zeng Qinghai leave happily with the drawings, he also took his work cap and walked towards the No. 2 workshop.

Walking into the No. 2 workshop, Li Tianfeng nodded with satisfaction, the allocation of all kinds of personnel is still relatively fast, and it is also relatively in place, in this regard, Hu Xiao has made great contributions, and the skilled workers, technicians, and management personnel are all recruited by Hu Xiao's human resources department.

The purchase of machine tools and equipment, the speed is relatively fast, not to mention the domestic equipment, the cycle is relatively short, the procedures are relatively simple, the workshop needs the domestic equipment has been basically in place, the imported equipment cycle is slightly longer, slightly troublesome, but also has been in place part.

Walking into the second processing workshop, the first impression is that there are more various machining centers in this workshop, which forms a more obvious contrast with the first processing workshop, and the first workshop is more of all kinds of lathes, especially a lot of CNC lathes.

The second processing workshop is located in the processing of various types of casings of aero engines, and the main processes of processing casings are milling, drilling, boring and other processes, and there are more machining centers. In addition, the technical content of the casing is very high, and there are many high-precision vertical machining centers required.

The casing of the aero engine must not be underestimated, and the technical content is extremely high.

The precision casting of the casing involves a lot of complex processes, and the precision requirements are also very high, after the casing casting is qualified, all kinds of processing are required, because there are many extremely demanding installation surfaces, installation holes, precision positioning holes, as well as lubricating oil circuits, fuel circuits, cable pipes and so on.

The processing of these holes and surfaces requires high-precision processing equipment, especially precision holes and bearing holes, which have extremely high precision requirements, and the requirements of the precision machining centers involved are also relatively high.

Therefore, the No. 2 machining workshop has the largest number of machining centers of all types.

Li Tianfeng saw that a lot of machine tools and equipment had been put into use, and some machine tools and equipment were being installed and debugged.

Walking to the front of an imported three-coordinate vertical machining, Li Tianfeng looked at it, and it was a flange part of Harry Burton Company that was being processed, and the machining center was boring on the part.

The parts are not big, but there are a lot of them, Li Tianfeng saw that dozens of parts were neatly placed next to the machine tool, and a relatively young worker, who seemed to be less than thirty years old, was operating the processing.

Li Tianfeng walked over, took the processing technology card on the work table and looked at it, this process is to process three Φ20 holes, the content of the processing is not much, but the requirements of these three holes are extremely high, the position is required to be within two wires, the diameter tolerance is only one and a half, the difficulty of processing is not small, fortunately, the material of the parts is relatively ordinary, if it is a high-temperature alloy or titanium alloy, such a process is very technical, and it is difficult to meet the quality requirements with such boring.

Surprisingly, this worker didn't know Li Tianfeng yet, and he was chattering again, seeing Li Tianfeng looking at the process card on his desk, he couldn't help asking: "Dude, the new arrival, is it a process technician in our workshop?" ”

There are new employees joining in the second workshop almost every week, everyone doesn't know each other, Li Tianfeng saw that people didn't know him, he couldn't help but be interested, and asked, "What about you?" Also new? ”

"I've been here for less than a month, and I've just finished the pre-job training, and I've only been on the job after passing the assessment, and this is the second batch of parts that have been processed?"

Li Tianfeng said with a smile: "It's okay, I just started to operate the imported three-coordinate machining center." ”

The worker smiled proudly: "I graduated from school to work on the operation of the three-coordinate machining center, already very experienced, but also got the senior grade certificate, but, the previous operation is domestic equipment, this time is imported equipment, buddy, don't say, our factory is really amazing, a lot of high-end imported equipment." ”

Li Tianfeng nodded happily, and then asked, "How is this process processed, are there any difficulties?" ”

"Dude, you are really a process technician in our workshop, it is difficult to process, a little bit, you see that the tolerance of this hole is too small, it is not very convenient to measure, and there are errors."

After speaking, the worker took out the watch piece used to calibrate the inner diameter dial gauge and said: "Look at this pair of watch pieces, the marked inner hole is Φ20.0128, but I found that the inner hole used to calibrate the inner diameter dial indicator on this pair of watch pieces is not a standard circle, and there is a certain ellipse.

Then, the worker picked up the dial gauge of the inner diameter, demonstrated it, and chose several directions to check the gauge, and the measured values calibrated in these directions were not consistent, with a difference of about three thousandths.

Li Tianfeng smiled and said: "This is normal, no one can process an inner hole into an absolute circle, there is always a little bit of irregularity, do you see this white paint mark on this pair of watches, do you know what it is used for?" ”

"What's this?" The worker hesitated for a long time, "I really don't know what a paint mark on this inexplicably does, buddy, what is this for?" ”

Li Tianfeng said: "This white paint mark is famous, and experienced workers know that it is calibrated at this position when calibrating the inner diameter dial gauge. ”

The worker's reaction was also fast, Li Tianfeng had not finished speaking, and immediately said: "Oh, I know, every calibration is in the same position, even if there is a certain ellipse on this inner hole on the watch piece, it will not be affected, and the measurement will be more accurate." ”

"Yes, that's the truth." Li Tianfeng nodded.

Li Tianfeng was about to take a closer look at the processing quality of this part, He Baitao saw Li Tianfeng from a distance, and immediately trotted all the way over.

"Mr. Li, I'll accompany you to take a look around."

This worker naturally knew He Baitao, who was the technical director of his workshop, and the worker was about to greet He Baitao, but when he saw He Baitao, he didn't look at himself, but greeted Li Tianfeng, and this appearance was exactly like a subordinate seeing a superior.

The worker swallowed back the words that came to his mouth, looked at Li Tianfeng in dismay, and thought in his heart, this, this, this will not be the big boss of his company, the general manager Li Tianfeng!

Li Tianfeng saw He Baitao and smiled slightly, "Okay, let's go over there and take a look." ”

The worker looked stunned, and didn't come back to his senses until Li Tianfeng walked away, hurriedly walked to the side of a machine tool, grabbed a master who came in early, and said, "Lao Zhang, who was the Li in Director He's mouth just now?" ”

"Xiao Shen, I really admire you, after doing it for a long time, you didn't recognize that it was our general manager!"

Today's two watches, the second one is sent! (To be continued......)
