Li Fanyu used his general design ability to push the progress of B-01 forward by leaps and bounds. After the design drawing was finalized and the team started modeling, he came to the power company and found Sun Guoyi.
He has extracted the complete production process of X super aluminum alloy from the materials laboratory. The value of this technology can be seen just from the 20 million redemption points.
Because X aluminum alloy is the basis for whether the entire design of B-01 can be established, Li Fanyu has asked Sun Guoyi to set up a small-scale production pilot after the production process was exchanged.
He had to find someone he could trust and be reliable to handle this matter. Pan Qiang was actually the first choice. But now as the number one figure in the group's production department, Pan Qiang really can't leave. Therefore, the production of super aluminum alloy can only fall on Sun Guoyi.
The production process of super alloy is very complicated, but fortunately, the technology for producing aluminum alloy materials in China is relatively developed and mature, and Zhengxin is not short of money now. Following Li Fanyu's instructions for small-scale production, he was willing to invest a lot of money, and the finished product was quickly produced.
While waiting for the success of X aluminum alloy, Li Fanyu led the team to once again optimize the performance of B-01.
……
After more than ten days of continuous revision and optimization, the final version of B-01 has been determined.
It was at this time that Sun Guoli sent news to Li Fanyu - according to the instructions, the trial production of X aluminum alloy has been successful!
After receiving the news, Li Fanyu directly convened the R&D team and carried the sand mold to the power company. Of course, we have received instructions from above and the Seventh Division, which has quadrupled its manpower, will definitely accompany us throughout the process.
Zhengxin Power Company, in a separate processing workshop.
Li Fanyu looked at the ten X super aluminum alloy raw materials in front of him and nodded with satisfaction.
"Old Sun, have you tested everything?"
Sun Guoyi nodded heavily, "Don't worry, Director Li, it's all done. We synthesized it strictly according to the method you gave, and after testing, the material performance has also reached the standards you gave!"
"That's good." Li Fanyu nodded and waved to the technical engineer on the side, "Come on, brothers, let's start work!"
With his order, the engineers who were already eager to try quickly started. Giving full play to the excellent style of Zhengxin R&D Center, "Wen Neng uses pens to do research and development, and Wu Neng works on lathes in the workshop", and directly does the work that should be a worker...
After more than two hours of high-temperature calcination, the ultra-high-strength No. 4X aluminum alloy was melted into a liquid state and poured into many completed sand molds.
The engine manufacturing process is quite complex. The raw materials must be molded into embryonic parts by sand mold infusion, and then put on the machine tool for three-pass turning and milling processing of roughness and fineness. Finally, heat treatment is required to further enhance the mechanical properties of the parts.
But when everyone opened the sand mold and put the first completed cylinder blank on the CNC milling machine, an accident happened...
In order to save time, everyone has sent the data in advance so that the processing program can be set for the CNC machine tool. But when the machine tool started working at the end, and the turning tool inside just came into contact with the accessory, a "sizzling!" sound was heard, and then a muffled sound.
Immediately afterwards, the operation panel of the CNC milling machine displayed a W yellow exclamation mark and automatically stopped the feed.
The blade... collapsed!
Seeing this scene, Li Fanyu slapped his head hard,
No. 4 X aluminum alloy is too hard, and ordinary CNC machine tool bits will definitely not work! Damn it, I forgot about it!
What material is the cutter head of CNC machine tools made of?
Carbide!
This thing is an alloy formed by adding 15% cobalt to tungsten carbide powder. It has high hardness, good strength and toughness, and is heat-resistant and wear-resistant. Even at high temperatures of 500 to 1,000 degrees, it still has good hardness performance. If calculated using Mohs hardness, the coefficient of carbide tip should be around 9.5, which is slightly lower than diamond. With the milling machine's high speed of more than 20,000 revolutions per minute, this metal alloy cutter head has always been able to cut steel like mud and iron like paper, let alone aluminum alloy.
Because X aluminum alloy is still in the confidential stage, the technical engineer responsible for programming the machine tool does not know how hard this material is. He only thinks it is harder than ordinary aluminum alloy, so he sets the feed amount slightly larger.
But when it comes to No. 4
Seeing this scene, the technical engineer glanced at Sun Guoyi and Li Fanyu in panic, "Sorry, sorry, Mr. Li Dongsun, I will correct the program immediately and reduce the amount of tool feed!"
Li Fan waved his hand with a silly smile, "Don't bother! Prepare all the blanks first. I'll go get something and I'll be back soon."
He said this, but he was smiling helplessly in his heart;
Reduce the amount of feed?
It's not even a millimeter for one minute. Where is the hardness? With the hardness of No. 4
Thinking like this, he quickly drove to the super material laboratory located in Laozhengxin Company.
I didn’t say anything when I arrived at the materials laboratory. I used my R&D points directly in the laboratory to redeem two sets of pure No. 5X super aluminum alloy. The material shape was set by him as a turning tool for lathes and milling machines.
There is no way, X aluminum alloy has such a high hardness, I am afraid there is no tool head on the market that can process it.
The only way is to use higher-level No. 5X super aluminum alloy!
Mohs hardness of 12 VS 9.8...fight fire with fire!
When Li Fanyu handed over the special cutter head to the technical engineer and replaced it with the carbide cutter head, processing was finally able to continue.
This time there was no problem at all. Under the power of No. 5X super aluminum alloy, the processing program set by the technical engineer immediately went smoothly.
There is no problem with the cutter head, and the characteristics of the aluminum alloy are revealed; wherever the cutter head goes, the required shape on the drawing is bored out with extremely precision! In this way, with more than a dozen machine tools operating at the same time, all the parts were processed in just a short time.
Looking at the boring holes on the engine block, Sun Guoyi was speechless. Such a hard thing turned out to be in such excellent shape during the machining process!
But the engineers on site did not give him any more time to marvel. They heat-treated the important parts as quickly as possible and assembled them together.
After a whole day of work, the B-01 engine assembly was finally presented to everyone!
Looking at the huge but extremely delicate machine on the assembly table, even Li Fanyu's eyes became a little confused.
Because the oil supply system and cooling system are concentrated inside the engine, the appearance of B-01 appears to be quite square.
After high-precision turning, the surface of No. 4
At first glance, if you don’t pay attention to its majestic body composed of two rows of six cylinders juxtaposed at an angle of 60 degrees, just looking at the surface, it is difficult to believe that this is an engine that will be installed at the heart of the tank.
The guy in front of everyone seems to be the hammer head of the giant war god! It also seems to be the heart of a giant steel dragon!
An engineer next to Li Fanyu stared at B-01 for a long time with an obsessed expression on his face, his face turned red from holding back, and it took a long time before two words came out of his mouth;
"Awesome!"
