Siheyuan starts from a better life

Chapter 743, Composite Armor

Jiang Yan led a group of technicians to the factory workshop, where various prepared parts and modules were already placed.

"Comrades, today we are going to carry out the first assembly of the five-axis CNC machine tool." Jiang Yan looked around and said solemnly, "This has epoch-making significance for our country's industrialization process. I hope you will be careful and ensure every link. All perfect.”

The technicians present were all in high spirits and gearing up.

"Don't worry, Mr. Jiang, we will ensure the quality and make this machine tool perfect!" an old technician said proudly.

"That's right, we will never be careless today. This machine tool is our pride!"

"Very good. Then, let's start assembling the rack first." Jiang Yan said.

So everyone quickly got to work and began to install the base and columns in an orderly manner. Jiang Yan guided and unscrewed the bolts himself.

"Thank you, Mr. Jiang, for your hard work. Let's do it." Several young technicians discouraged him.

"It doesn't matter, I want to participate personally. This is also a valuable experience for me." Jiang Yan said as he tightened the pillar firmly, but he did not forget to teach the few people next to him while doing it.

After the machine tool frame was installed, Jiang Yan gave it a try, and then led them to install the spindle system, feeding system, tool magazine system, etc.

"Okay, everything on the machine tool has been installed. Now we start to install the control system. This thing is the top priority," Jiang Yan said.

"General Manager Jiang, I'll be in charge of this!" A technician stepped forward in response.

He carefully took out the control circuit board made by Jiang Yan and installed it inside the console.

After installing it, Jiang Yan walked over and took a look. There seems to be no problem at all.

"Okay, the next step is software and logic programming. I'll do this," Jiang Yan said calmly.

He turned on the power and quickly entered lines of code on the panel to set various logical relationships.

All the technicians present held their breath, fearing that they would accidentally destroy Chief Engineer Jiang's programming. Seeing that everyone was looking at it seriously, Jiang Yan did not explain it, but kept typing.

After more than ten minutes, Jiang Yan finished entering the last piece of code and gently pressed the "Confirm" button.

At this time, the newly assembled machine tool suddenly made a loud "roar" and the five axes started running rapidly!
"Successful!" Jiang Yan announced loudly and excitedly.

"Success! Long live!" The technicians cheered, with tears filling their eyes with excitement.

"We succeeded, we succeeded." Everyone gathered around and congratulated. A few of them even hugged each other, and the scene was quite good.

"Okay, okay, let's pause for a moment and start testing the machine now." Jiang Yan stopped everyone's enthusiasm, "Xiao Zhang, go get some alloy blanks we prepared."

"I'll get it right away!" Xiao Zhang responded and ran to the material storage room, pushing several materials to Jiang Yan.

A few minutes later, several pieces of alloy blanks were placed on the machine tool workbench.

Jiang Yan sat on the console and started the CNC program, and the machine tool immediately started running according to the control instructions.

The high-speed rotating spindle begins high-speed cutting of the aluminum alloy blank.

"Hiss——" Amidst the harsh mechanical sound, the machine tool rapidly moved five coordinate axes, and the tool flew back and forth on the metal.

"This, this, this speed is too fast!" Lao Li stared at the tools on the machine tool flying with wide eyes.

"I'll go, this speed is much faster than other machine tools!" A technician couldn't take his eyes away.

The cutting tools on the machine tool are as if they are alive, shuttling at high speed under the precise control of each axis, quickly cutting the blank into shape.

"It's done!" Looking at the parts that were about to be processed, a technician said with disbelief.

"Our ordinary machine tools cannot process such complex curved special-shaped parts at any cost!"

"To make this kind of piece, ordinary machine tools can only process a rough blank, and the rest needs skilled old fitters to spend several days hammering out the rest." A group of technicians came over in surprise and started talking about it.

Lao Li carefully picked up the processed special-shaped test piece and brought it to the operating table like a priceless treasure.

He picked up a precision micrometer and carefully measured every critical dimension.

"The dimensional error of each feature of the part is controlled within 0.01mm, which is simply the ultimate in finishing!"

Lao Li's hands couldn't help but tremble a little. He took a step back and sat down on the ground.

"This, this is the first time I've seen such machining precision."

If he hadn't seen this with his own eyes, Lao Li wouldn't have believed that a machine could produce such precise heterosexual parts.

Other technicians were also stunned and speechless by the processing efficiency and precision. The scene was completely silent as everyone was trying to digest the scene they just witnessed——

The magnificent industrial power displayed by the five-axis CNC machine tool!
Hearing that the part error was completely within control, a group of technicians rushed forward again, scrambling to see the part.

An old fitter also squeezed into the crowd to see this magical test piece.

But when they took the parts in their hands and inspected them carefully, all of them looked a little ugly.

"This accuracy is better than my manual processing."

"Can we old guys still have any work to do now?"

"What can we do in the future?"

Several old fitters looked at each other, a little at a loss. They looked down at their calloused hands, and then looked up at the rapidly rotating spindle on the machine tool. I couldn't help but feel a sense of melancholy in my heart - will the manual skills I have worked hard for most of my life be eclipsed in front of this cold machine?
My heart sank little by little.

"Don't worry, everyone, your skills are still very valuable!" Jiang Yan's voice sounded in time.

Jiang Yan saw their worries and walked over and patted them on the shoulders: "You skilled craftsmen are the backbone of the factory, okay! Machines can never replace your experienced hands!"

"It's just a tool. We still need everyone to use their wisdom to create more miracles!" Jiang Yan encouraged.

Hearing Jiang Yan's encouragement, the eyes of these old workers lit up again.

After dealing with the five-axis machine tool, Jiang Yan took several engineers to the No. 3 workshop of the institute.
The third workshop belongs to the steel rolling workshop, where there are several large rolling mills specially used for rolling thick steel plates. It is used to support several other workshops.

"Comrades, we need to make some modifications to these rolling mills to meet the needs of an important project." Jiang Yan said mysteriously.

"Ah? What project is it for to renovate the rolling mill?" an engineer asked curiously.

"Well," Jiang Yan paused, "anyway, it is a very important project and will be of great benefit to the development of the country. Just do what I say."

"Oh, okay then, Mr. Jiang, just give your orders."

So the engineers began to modify the rolling mill according to Jiang Yan's requirements. Adjust the roller spacing to a specific size, install customized rolling modules, and optimize the mechanical properties of the entire structure.

Jiang Yan checked each step one by one to ensure that his standards for armor plate rolling were met.

"Phew, it's done!" After two days, the transformation work was successfully completed.

"General Engineer Jiang, we have met every indicator you requested. Can this machine now meet the needs of that mysterious project?" the engineer asked.

"Okay, well done! Your work is of great significance to that big event!" Jiang Yan said with a smile.

Although the engineers didn't know what was going on, they proudly held up their chests.

Jiang Yan knew that with this modified steel rolling mill, the manufacturing of armored steel plates would be extremely smooth. When tank armored plates began to roll off the production line in batches, they would naturally understand how important their modification was.
