After the general car is completed, the next step is the first process of counting the car.

This is a Dalian CNC lathe, the CNC master Zhou Jinhai who operates the CNC machine tool looks about 30 years old, and he is also a skilled worker, and the machine tool has been put into trial operation according to the regulations.

The first blank part of the general car that completed the last process has been taken and placed next to the CNC machine tool, and Zhou Jinhai is installing the CNC tool according to the process requirements.

Li Tianfeng took a look at the processing site, saw that it was normal, and left here, Li Tianfeng, as the general manager of Tianfeng Technology, still has a lot of things to do, and it is impossible to stay at this processing site all the time.

Zhou Jinhai used to be a number of lathe workers in an auto parts company, recruited by the guò job fair, these front-line workers in the No. 1 workshop, some of them have been engaged in the machining of aviation parts, and some have not been contacted, like Zhou Jinhai, who has only processed auto parts for many years.

When he first entered Tianfeng Technology Company, he trained for several days, and Zhou Jinhai also knew that the processing of aero engine parts and auto parts was not the same, and the processing of aero engine parts was much more rigorous and exquisite.

With a cautious attitude, Zhou Jinhai carefully installed the CNC turning tool to ensure that it was foolproof, and after installing the turning tool, the parts were loaded on the machine tool in strict accordance with the process requirements, and after the parts were installed, the parts were carefully corrected, and the process requirements were fully met.

Then, carefully set the tool, before processing, but also simulated the CNC program again, to make sure that it was foolproof, Zhou Jinhai began the formal processing, close the machine tool safety door, press the CNC machine tool start button, through the glass of the safety door, you can clearly see the processing situation inside the machine tool.

As the machining program starts, the spindle of the machine tool begins to rotate, and the speed is getting faster and faster, reaching more than 100 revolutions in just a few seconds, and at the same time, the milky white coolant is also sprayed out of the nozzle, and a large amount of white coolant is sprayed on the parts.

Machine tool holder movement, accurate positioning, brand new hard turning tool, "hiss" a light sound, easy to cut into the part, because it is rough machining, the use of high speed, large feed, and strive for the best processing efficiency, the lowest tool wear, to achieve the best economic benefits.

The processing process parameters, including speed, feed amount and other parameters, when the processing process regulations were compiled, Li Tianfeng or Zeng Qinghai personally checked them, so naturally there would be no problems.

Through the safety door of the CNC machine tool and seeing the processing situation inside, Zhou Jinhai was secretly speechless, thinking in his heart, the speed is so fast.

The processing is really fast, a large number of metal chips, curled, is a large number of rapid cutting down, originally a blank part, the surface was originally pitted, there is a layer of unsightly oxide scale, at this time, is revealing a beautiful metal color, very bright.

The machine tool emitted a slight, steady beep, according to the CNC program, the processing was normal, and it didn't take long for a large number of metal chips to fall from the metal chip groove of the machine tool.

Rough machining, the machining allowance is very large, there are naturally a lot of metal scraps, some machinery factories do the processing business of E factory, relying on these cut metal scraps can sell a lot of money.

Like the first stage of the compressor disc blank that is being processed now, before the processing, the weight of the blank is about a dozen kilograms, and after the completion of several cars, rough machining, semi-finishing, it will slim down a lot, a large amount of margin is turned down, and the weight of the parts is less than half of the original.

In less than an hour, the machine began to retract, and Zhou Jinhai knew that the program was about to end, and the process was about to be completed.

After about a minute or two, the machine stopped, and Zhou Jinhai hurriedly opened the safety door of the machine tool, a little eager to take a look at his first part. Holding the air gun and blowing the coolant on the surface of the parts, Zhou Jinhai looked at the parts.

Not bad, not bad.

Just looking at the surface quality is very gratifying, the roughness is very good, there are no burrs, there are almost no processing defects, and then I took the measuring tool to measure the size, all qualified.

As soon as he was in the morning, Zhou Jinhai began the processing of the second part......

…

Li Tianfeng's office.

This is a grand office, a large and high-grade desk, and a boss chair, Li Tianfeng is sitting there, very stylish.

Li Tianfeng answered a few phone calls just now, and now, he is opening the curtains of the office and looking outside, taking a break, and taking a breath by the way. Li Tianfeng's office is on the top floor of the newly completed office building, and the location is very good, condescending, just in time to see the situation of the main factory door, at a glance.

"Knock, knock, knock......"

There was a knock on the door, and Li Tianfeng knew that it should be Zhang Can. Li Tianfeng retracted his gaze, walked to his comfortable and wide boss chair and sat down, and then said loudly: "Come in!" ”

It was Zhang Can who pushed the door in, "Mr. Li, are you looking for me?" ”

"Hmm." Li Tianfeng nodded, and then said, "Zhang Can, let's get used to it!" ”

Zhang Can thought that Li Tianfeng was looking for something important about himself, but he didn't think about it, Li Tianfeng asked himself like this, Zhang Can said: "Mr. Li, it's okay, I'm more motivated than in Factory E, in addition, the stage here is very big, and the development prospects are very good, thank you Mr. Li." ”

Li Tianfeng said: "It's good to get used to it, in the past few months, I know that you have all worked hard, but I still want to add another burden to you, how about it?" Is there confidence? ”

Add a burden?

That is to promote himself, Zhang Can was excited in his heart, and hurriedly said loudly: "Mr. Li, I have confidence, I will not disappoint Mr. Li!" ”

Because it was a formal occasion, the two also seemed very formal, not talking and laughing like in private.

"Okay, just have faith." Li Tianfeng sighed and said: "Zhang Can, the No. 1 workshop has officially started to process parts today, and the management of the No. 1 workshop is about to get on the right track, how about you go to the No. 1 workshop as the technical director?" ”

Technical Director!

Zhang Can was very excited, a few months ago, Zhang Can was an ordinary technician in Factory E, and now, he is actually the technical director of Workshop No. 1. Workshop No. 1 is very large, and if it really develops, there will definitely be three or four hundred people.

Thinking that he would manage so many people under his command in the future, Zhang Can was even more excited.

Seeing that Zhang Can was a little excited, Li Tianfeng couldn't help but smile slightly, got up, patted Zhang Can's shoulder and said, "Let's go, let's go to Workshop No. 1 to have a look and see how the processing is going." ”

"Okay."

Together, the two walked towards the No. 1 workshop, and as soon as they walked into the workshop, it was in full swing, and the parts were being processed.

The two walked around the workshop slightly, and just walked next to Zhou Jinhai's CNC lathe, at this time, Zhou Jinhai had completed the processing of the second part, and the third part was also being processed on the machine tool.

Seeing Li Tianfeng and the two coming over, Zhou Jinhai hurriedly said, "Mr. Li is good!" ”

Li Tianfeng nodded slightly, looked at the two parts that had been processed in the station equipment (wooden parts box), and saw that the surface quality of the two parts was good, Li Tianfeng asked: "How is the processing situation?" ”

Zhou Jin also hurriedly said: "Mr. Li, the processing is very smooth, the two parts that have been processed are all qualified, the surface roughness is also very good, in addition, the wear of the turning tool is relatively small, and there is no problem with the new tool I installed when I started processing and then processing a few parts." ”

Like this kind of processing, the processing cost is mainly the loss of turning tools, the loss of machine tools, followed by electricity costs, plant depreciation costs, labor costs and so on.

Because the processing technology regulations are personally checked by Li Tianfeng, and the parameters are also selected by Li Tianfeng, the parameters are selected reasonably, the processing efficiency is naturally very high, and the loss of the turning tool is naturally very small, so that the cost is reduced all of a sudden.

If it is a general mechanical processing plant, without this technical strength, the parameter selection can not be so suitable, the processing efficiency is much lower, and the loss of turning tools is also very fast.

Take the first-stage roulette of the compressor being processed, the same is the number of car processes, Li Tianfeng only needs 30 or 40 minutes to complete the processing, using four different types of CNC blades to form a set of processing tools, this set of CNC turning tools can process at least five or six parts, or even seven or eight parts.

In other general mechanical processing plants, such a process is at least two hours or more, and the processing time is more than three times.

In this way, the judgment is made!

Technology is strength, processing the same parts, other people's profits may not be one-third of Li Tianfeng's.

This is the status quo in China, because the mechanical processing technology is generally not strong, the processing efficiency is not high, and the processing cost of parts remains high, which leads to the high cost of aero engines.

The same turbofan B engine, Lao Maozi also produces, but the manufacturing cost is low, the quotation is naturally low, even lower than the price of the domestic turbofan B engine, you know, our labor costs, other costs, are lower than Lao Maozi.

The price of the engine is higher than that of others, and the quality is not as good as others, so that many people have the idea that it is better to buy ready-made ones than to develop them themselves, and it is better to buy them than to manufacture them themselves.

Li Tianfeng saw that the two parts in the wooden box had been processed for this number of car processes, leaned down, took out one, and put it on the station table next to the machine tool.

However, Li Tianfeng quickly saw the clues, and thought in his heart, it's not good, something is wrong, something is wrong.

Glancing at Zhou Jinhai, Li Tianfeng knew that Zhou Jinhai had never been engaged in the processing of aviation parts, and now there was really a problem.

About half of the dozens of workers recruited in this batch have no experience in aerospace parts processing, so they may have similar problems, and if this is the case, it will be troublesome.
