The technology room, busy and quiet.

Li Tianfeng is writing a paper, Li Tianfeng is preparing to publish some papers in some well-known journals at home and abroad, Li Tianfeng's skills are there, and this paper will definitely be adopted and published.

Now, the blade disc of the second-stage compressor of the turboshaft C engine has begun to be processed, Li Tianfeng looked at the time and thought in his heart, the first part should be about to complete the milling process.

Keeping his paper, Li Tianfeng walked out of the process technology room. It was He Wei who processed the blade disc of the second-stage compressor of the turboshaft C engine. He Wei's skills are good, and Li Tianfeng understands some matters as long as he explains them a little, and he understands them at one point, and Li Tianfeng saves a lot of things.

Now He Wei has admired Li Tianfeng so much, Li Tianfeng said that He Wei would do whatever he wanted. Walking next to this precision five-axis linkage CNC machining, He Wei was already disassembling the parts, obviously, the first part had completed the milling process.

Seeing Li Tianfeng, He Wei said happily: "Li Gong, the first part is just finished, and it is the official time for you to come." ”

Watching He Wei disassemble the parts and clean them up, Li Tianfeng personally picked up the measuring tool with great interest and measured the relevant dimensions processed.

He Wei next to him said happily: "Li Gong, I have convinced you, you are the first person I admire, this part is processed quickly and well." ”

Fast and good, naturally the best. High efficiency and good quality are things that many people dream of, and Li Tianfeng has achieved it seemingly lightly.

Take the part that He Wei just processed, such a complex blade disk, Li Tianfeng only took more than ten hours to count and mill all the blades, according to the previous situation and processing level of the E factory, it takes at least dozens of hours to mill the blades with a simpler blade disk.

In the middle, it is not enough to calculate the economic benefits alone, not to mention the light gnawing off this hard bone, which can be called the perfect smooth processing of this part, no wonder He Wei admired Li Tianfeng so much.

He Wei operates the five-coordinate precision CNC machining center every hour of depreciation, plus management costs, labor costs, electricity costs, etc., every hour is more than five or six hundred, if continuous processing for dozens of hours, the processing cost is at least more than 20,000 yuan, not counting the cost of tools.

Dozens of hours of continuous processing, the cost of the loss of the tool is also a lot, because the precision CNC machining tool is less than hundreds of yuan, expensive is thousands of yuan, processing such a blade disk, the cost of the tool is at least thousands of yuan.

Li Tianfeng only took more than ten hours to process the parts smoothly, less than one-third, time greatly saved, machine tool depreciation, management costs, labor costs, electricity costs, etc.

Li Tianfeng was interested in measuring this freshly processed part, and he sighed in his heart that the processing level of factory E is still relatively advanced in China, and even if this part is processed according to the processing level of factory E, it will cost a lot.

It is no wonder that the price of domestic aero engines can be in line with international standards, largely because the processing cost cannot be lowered. Take the turbofan B engine currently produced by Plant E as an example, the price of this engine is more than 8 million units.

The same engine, Lao Maozi also sells, because the turbofan B engine is produced from Lao Maozi's imported technology, Lao Maozi's same turbofan B engine quality is better than that of factory E, but the price is cheaper, because although the labor cost is expensive, the processing cost of others is much lower than yours.

Li Tianfeng thought in his heart, if he opened a oneplus machinery processing factory, specially for the processing and supply of accessories for aviation engines like factory E, and had his own technology there, the processing cost would be greatly reduced, maybe the E factory would have to pay 20,000 yuan for the processing cost to process the parts, and he might be able to process it at a cost of 10,000 yuan, so it would be difficult for him to make money if he didn't want to.

Opening a onePlus machinery processing plant to process parts for an aero-engine manufacturing company such as Plant E, starting with processing parts for others, may be the first step to take in the future.

However, now Li Tianfeng has no funds, such plans and ideas can only be hidden in his heart temporarily, and before there are no funds, he can only honestly work as his own technician in Factory E.

"Li Gong, how about it, the quality of the parts is very good." He Wei saw that Li Tianfeng had measured a lot of dimensions by himself, and asked on the side.

Li Tianfeng smiled happily and said: "This part is good, the processing quality is very good, after finishing the first piece, continue to process the second piece, and process all the parts in this batch in one go." ”

"Yes." He Wei was happy in his heart, and thought in his heart that after he finished processing all these parts, his salary this month would definitely not be low.

He Wei is a technician or a skilled hand, and he has a lot of monthly allowances, but he also gets piecework wages, and the so-called piecework wages are how many parts are processed every month, how many working hours are converted into how much money are then calculated into the monthly salary.

For example, the second stage compressor blade disc of the turboshaft C compressor, according to the original processing technology level of factory E, even if it takes at least 50 or 60 hours to process this number of milling processes, the working hours quota of the precision machining center has set the working hours for this process, that is, 150 working hours, and each working hour is 5 yuan.

If it is really according to the normal processing level of factory E, it actually takes six or seven days to process such a part (eight hours a day), and He Wei can get 750 yuan after processing such a part.

In fact, Li Tianfeng's technical level is very high, this piece of turboshaft C compressor second-stage compressor blade disc that could have been processed in six or seven days is actually processed in one day, at most one and a half days, and it is 750 yuan to complete one piece.

A few days ago, He Wei has finished processing a total of two pieces of first-stage compressor blade discs, and now he will process four second-stage compressor blade discs in one go, and there are four third-stage compressor blade discs in the future, so that He Wei's salary this month is a little frighteningly high.

For front-line workers, factory E is a piecework hourly wage, an average worker's monthly piecework wage is about 2,000, plus basic salary, seniority salary, subsidies, etc., and then deduct pensions, housing provident funds, etc., the average worker takes the salary of more than 2,000 yuan per month, in a third-tier city like Songzhou, such a salary is not high or low, there is no problem with supporting a family, and it is impossible to get rich.

He Wei's salary this month is at least nearly 10,000 yuan, such a high salary, in this E factory with a common salary of two or three thousand, it is a little scary.

He Weile was in a very good mood, and said to Li Tianfeng: "Li Gong, are you free at night, your sister-in-law has good skills, how about having dinner at my house tonight?" ”

Thinking about being alone, he usually eats in the factory canteen, so Li Tianfeng said briskly: "Master He, then I'll bother you, come over for a meal at night and improve the food." ”

Seeing that Li Tianfeng agreed so quickly, He Wei was also very happy, "Then it's decided, I'll wait for you at home at night." ”

The two chatted for a few words, and then Li Tianfeng explained to He Wei a little, such as which tool is worn out to be sharpened, what problems should be paid attention to when clamping parts, etc., after speaking, Li Tianfeng returned to the process technology room in a good mood.

I looked at the paper I wrote again, changed it slightly, and after archiving, Li Tianfeng saw a worker walking over with a processing card, Li Tianfeng knew this worker, a middle-aged CNC lathe operator in the production line of large disc parts.

"Li Gong, you can help me take a look at this counting process, this process takes five or six hours to process a part, and it is often difficult to guarantee these sizes......"

The worker told the actual situation of the process, Li Tianfeng is a technician of the large reel line, and he is also familiar with the other party, and he did not shirk it, he looked at the process and asked some questions, Li Tianfeng basically knew it in his heart.

"Master Zhang, you wait a minute, I will improve the processing procedure of this process, and the situation should be much better."

Seeing Li Tianfeng agree, Master Zhang was very happy, and hurriedly said: "Li Gong, then you have to worry about it, I'll wait for you below." After speaking, Master Zhang left happily.

Li Tianfeng was also more happy in his heart, and people took the initiative to find him to help improve the processing procedures, which was a recognition of himself, and Li Tianfeng immediately began to improve the processing procedures of this process.

Changed a few more suitable CNC turning tools, the processing path is more favorable, and combined with the situation of these CNC turning tools and the CNC lathe, Li Tianfeng greatly optimized the processing program.

After getting the program done and simulating it again, after making sure that there was no problem, after opening the program change order and signing it, Li Tianfeng sent the new program down.

Because it was the first piece of processing, Li Tianfeng personally stood next to the CNC lathe and tracked the processing of the first piece. The CNC lathe rotates rapidly, a large number of metal chips are cut down quickly, and the safety door glass of the machine tool is simply pleasing to the eye.

"Li Gong, this speed is at least one or two thousand revolutions, which is several times higher than the previous speed of hundreds of revolutions." Master Zhang looked surprised.

Li Tianfeng nodded and said: "Yes, I have given full play to the potential of CNC lathes and these CNC turning tools to the greatest extent, greatly improving the cutting speed, optimizing the processing method and tool path, and effectively controlling the deformation of the parts in the processing. ”

"Ahh Master Zhang was surprised, and immediately became full of interest and enthusiasm, and began to make preparations before processing.
