Chapter 186 Blade Grinding
"Damn it's 9:30!"
After waking up after a sleep, Li Tianfeng saw the time. It was already past nine o'clock in the morning. He couldn't help but shake his head and thought to himself, I really drank a little too much last night. ←
I hurriedly got up, washed up, and was about to rush to the company because I promised Zhang Haiping to visit the company today. It was so late now, so there was no reason for Li Tianfeng to be in a hurry. In addition, Li Tianfeng also knew that the joint environmental and safety inspection team had probably arrived at Tianfeng Technology, and at this time, I was probably already conducting inspections.
I hurried downstairs, ran to the restaurant to drink a glass of warm soy milk, picked up a big bun, and ate it while walking.
Seeing Li Tianfeng's hurry, Xiao Ping immediately said with concern: "Son, slow down, eat a little more before leaving. It was really true last night. What could it be that drinking so much will damage your body?"
"Mom, it's too late. I have many important things. I have to hurry to the company." Li Tianfeng said loudly, as he walked out of the villa gate, started the car, stepped on the accelerator, and drove quickly towards Tianfeng Technology.
Li Tianfeng's parents had come to Songzhou more than a month ago. They were reluctant to leave the town, but their son, daughter and son-in-law were all in Songzhou. The two old friends finally came and lived in the villa and took care of Li Tianfeng's life.
In fact, there is no need to take care of it. Li Tianfeng was afraid that his parents would be tired, so he hired a middle-aged nanny to do housework and get some food. Li Jianjun and Xiao Ping were basically very leisurely. But Li Tianfeng could still feel a strong sense of warmth when his parents lived with him.
Let’s talk about Li Tianfeng, and hurried to Tianfeng Technology. As soon as he arrived at the office, Liu Wei came in and reported: “Boss. The car that picked up Director Zhang Haiping has been sent out. In addition, the joint inspection team led by Tang Kaiyu, deputy director of the Municipal Environmental Protection Bureau, has arrived at the company and is undergoing inspections, accompanied by Tan Yan and Minister Cai Bin.”
Li Tianfeng took a sip of warm tea and did not take the matter of the inspection team to heart. Instead, he smiled and said, "Mr. Liu, it seems that Zhang Haiping had drunk too much last night and had not yet gotten up."
Liu Wei said: "Boss, Director Zhang Haiping's alcohol tolerance is really good. Last night, he drank almost a pound of white wine alone, which is a huge amount."
Li Tianfeng nodded. Zhang Haiping was so generous when drinking. Thinking of the situation last night, he couldn't help but smile. Then he said, "Mr. Liu, Zhang Haiping has arrived to notify me that I will process some documents first."
"Okay." Liu Wei gently withdrew and gently closed the door of Li Tianfeng's office. Li Tianfeng first processed a few documents, and then read several test reports of the "tfwz001" type turboshaft engine.
Many engine parts have completed the first batch of processing. Each of the first batch of parts has three or five pieces. They are mainly used for process verification, as well as various tests, design verification, performance verification, and even force analysis, or limit tests.
A new aircraft engine is necessary to conduct a large number of various tests and verifications at the beginning of its development. After completing a large number of various tests and verifications, the process problems will be improved one by one based on these series of design problems found during the test and verification process.
After such improvements and improvements are completed, the second batch of parts will generally be reprocessed, and if necessary, a second round of various tests and verifications will be carried out. After confirming that there is basically no problem, the first engine will be assembled.
The first aircraft engine assembled is the first verification machine, which requires various test runs, overall performance verification, etc. After the first verification machine, there may be a second and third verification machine. After all verifications, there will be no problems with the production license, design and shaping, etc.
At present, the design work has been basically completed, and the first batch of processing of most parts has been completed. The first round of comprehensive tests and verification work for various parts has begun. Li Tianfeng did not dare to take it lightly. He had to take a look at almost every test and verification report by himself.
………
It was already after 10:30 in the morning when Zhang Haiping reached Tianfeng Technology Company. The two met. Zhang Haiping said, "Mr. Li, I laughed and got up a little late."
Li Tianfeng also smiled and said, "No, no, I almost couldn't get up, I just arrived at the company."
After a few greetings in the reception room, Zhang Haiping said enthusiastically: "Mr. Li, if it is convenient now, take me to your processing site to take a look and let me have a good understanding of your turboshaft engine."
Li Tianfeng said readily: "No problem, then let's go to workshop No. 1 first."
So, under the leadership of Li Tianfeng, I first visited the No. 1 workshop and the No. 2 workshop, and then went to the No. 3 workshop in the afternoon.
At noon, Li Tianfeng warmly welcomed Zhang Haiping, but neither of them drank anymore. At work in the afternoon, they came to workshop No. 3 together.
Overall, Zhang Haiping was very interested in seeing such advanced, modern and huge workshops and also had a high evaluation of Tianfeng Technology.
Now, when you walk into the professional blade processing workshop of workshop No. 3 and see a large number of advanced equipment, Zhang Haiping said with emotion: "Mr. Li, if you don't come to take a look in person, you really can't imagine that Tianfeng Technology will have such a level, such hardware facilities, and such high-level management, I am full of confidence in your axle engine being developed."
After receiving such evaluation, Li Tianfeng was in a good mood and was also full of confidence in his first aircraft engine.
When he walked into workshop No. 3, he saw neat machine tools and equipment. When he saw workers processing parts, Zhang Haiping walked excitedly to a CNC electric spark machine tool.
After seeing the parts being processed, Zhang Haiping said: "Tianfeng, it seems that Pratt & Whitney has processed a lot of parts here."
In workshop No. 1 and workshop No. 2, Zhang Haiping saw some parts of Puhui Company that were being processed. In workshop No. 3, he saw parts of Puhui Company, so Zhang Haiping said this.
Tianfeng Technology and Puhui Company have a large scale of cooperation. Now, only some parts have begun to be processed one after another. Thinking of this super large order with Puhui Company, Li Tianfeng couldn't help but smile happily.
Li Tianfeng said: "We and Puhui Company are in-depth cooperation, and we process many parts in Puhui."
Zhang Haiping said: "Mr. Li, the requirements for Puhui are very high. I heard that many domestic aviation companies have contacted them before, but they ended up losing their quality requirements because they could not meet their quality requirements. Unexpectedly, under the strict quality requirements of Puhui Company, Tianfeng Technology has succeeded, which is amazing."
Zhang Haiping gave Li Tianfeng a thumbs up.
After looking at this large CNC electric spark machine, the two of them talked and laughed, and walked towards a large equipment not far away.
This is a large CNC grinder, which is large and fully enclosed, and is processing parts. Looking inside through the closed safety door glass, it splashes in it, and the milky white coolant is sprayed on the processed parts at a certain pressure.
At the beginning, Zhang Haiping thought it was a large five-axis linked milling machining center, but after a little look, it was not a CNC milling machining center, but a grinder that he had never seen before. The parts he was processed were actually a blade of two or three hundred millimeters long.
"Mr. Li, is this?"
Obviously, Zhang Haiping is a little confused about the situation, which completely subverts his understanding. Generally speaking, the processing of blade and blade type uses five-axis linked CNC milling, but now it is a CNC grinding machine in front of him, and the blade and blade type is grinding at high speed.
This is Li Tianfeng's new initiative. It is definitely a new process and technology. In Li Tianfeng's memory, the high-speed and high-precision grinding technology of blade-shaped blades has truly matured after more than ten years, after the technology is mature. It gradually tends to completely replace CNC milling.
Li Tianfeng said: "Director Zhang, this is a high-speed and high-precision grinding of blade-type blades. Its machining accuracy, blade surface roughness, etc. are more than one level of accuracy than CNC milling. It is a brand new process technology."
Upon hearing this, Zhang Haiping's eyes lit up and became interested. Unexpectedly, Daotianfeng Technology has this new technology. Zhang Haiping understands technology and has research on aviation engines. After looking at it, he asked.
"Mr. Li, this five-axis linked CNC grinder is a bit weird. The grinding wheel is very small, and the machine tool is something I have never seen before."
Li Tianfeng said: "This five-axis linkage CNC grinder is a professional blade grinder. We jointly developed and developed it with a famous university in China. The grinding wheel is also specially made, which is different from ordinary grinding wheels."
Zhang Haiping said: "No wonder I have never seen it before. Mr. Li. The processing efficiency is generally very low when grinding. It will take a long time to grind a blade like this."
According to general understanding, grinding is a bit of work, which has very low efficiency, especially the material removal rate is very low. It may take half a day to grind a few wires. If milling, you can easily mill the margin of dozens of wires with one cut.
Unexpectedly, Li Tianfeng shook his head and said, "No, no, Director Zhang, that's the traditional view. We are grinding at high speed, and the linear speed is very fast, ten times the traditional grinding speed, and dozens of times the processing speed, and the processing speed is much faster than milling."
What is much faster than milling!!!
Zhang Haiping was shocked and knew the value of it. Mastering such grinding technology means mastering the ability to process various high-precision and high-quality aircraft engine blades.
Zhang Haiping said: "Excellent, this has opened my eyes."
While the two were talking, they just completed the processing of the blades on the machine tool. The worker who was operating took off the blades. Seeing this, Zhang Haiping took a few steps forward and looked seriously.
Zhang Haiping is also an expert. Seeing that the surface of the blade is very smooth, its surface roughness is definitely below 0.4. The surface of the blade is processed almost like a mirror, which can reveal a human shadow.
Suddenly, Zhang Haiping was excited, as if he saw an art treasure. He was careful, his hands trembled slightly, and he gently stroked the leaf, as if he was touching a piece of silk.
