Rebirth of Military Workers

After entering the workshop, from the gate to the inside of the workshop, there are three glass doors in succession. There is a distance between each two doors, and the surroundings are also separated by glass.

In the first space, fans are arranged on the top and on both sides to blow away the dust from the people who enter the workshop.

In the second space, it is to eliminate static electricity.

This is China's first constant temperature and dust-free precision machining workshop. Inside are installed CNC lathes, CNC milling machines and three-axis machining centers from the United States. The number is small, but each one is regarded as a treasure. This is a batch that the Americans privately sold to China after the restoration of diplomatic relations between China and the United States. Advanced CNC machine tools.

How much foreign exchange was spent, how much energy was spent, it is estimated that it is not clear to the people who participated.

It took four years from the negotiation to the final equipment to China.

The CNC machine tools in the entire workshop belong to the advanced strategic technical equipment prohibited in the Batumi Agreement!

It wasn't easy, and the domestic personnel naturally regarded these high-end and top-level processing equipment as the ancestors' supply, and they were afraid that someday the ancestors would choose to quit.

Therefore, such a workshop was specially established.

After a fault occurs, it is often necessary to mobilize a group of technical personnel to have a meeting to discuss, formulate various plans, and lead a series of procedures for approval before troubleshooting can begin.

Xie Kai knows very well that he used to laugh at his father's generation of technicians. As they grow older, they understand why their parents treat these devices so carefully.

The domestic technical force is advancing by leaps and bounds, and they are qualified to strike without caring about the failure of top equipment.

broken?

They have rich repair experience; even if the repair is not good, it doesn't matter. The ones that can be produced in China can be replaced directly, and the ones that cannot be replaced are bought! The government has money.

Not in this era. The number of CNC machine tools in the country, combined, is not even as large as Xie Kai's and the same time as a medium-scale mechanical processing factory. Technicians have no accumulated experience, so naturally they have to be careful. Domestic production is not available, foreign countries are blocked, and money cannot be bought, let alone no money.

Both technicians and managers in the workshop wear white coats and white anti-static caps.

The equipment was broken and did not stop. Technical workers were training, and the technicians were frowning around the spotless machine tool masters to discuss maintenance plans.

Seeing a group of people coming in, everyone's eyes were cast over.

"Xie Gong, is there a solution?" A young technician with glasses, who didn't care about coming in, asked Xie Jianguo eagerly.

Xie Jianguo nodded, "Get ready to take down the PLC control system. Prepare to replace the burnt chips and electronic parts inside."

"Xie Gong, this..." The young man looked at Xie Jianguo in surprise.

"Take it all apart?"

"Approved above?"

"Replace the internal chip, what about the system program? What if the chip does not match?"

Almost all the technicians gathered around and asked their doubts.

Knowing the fault, they were afraid to disassemble and replace it due to technical problems.

The Americans gave the equipment only simple technical information. Unless they have a thorough understanding of the internals of the PLC control system, who would dare to replace them?

After the replacement, the system had to be re-programmed in machine language, and even the hardware was not fully understood. The programming aspect was even more problematic.

"Don't worry, it's okay." Xie Kai said to the youngest technicians who are ten years older than him, and then to Xie Jianguo, "Dad, lend me your repair tools, a full set. "

A bunch of military leaders are staring nearby, and Xie Jianguo can't say discouraged words.

Immediately trot to get tools in the maintenance room.

The technicians in the precision workshop all know Xie Kai, and they don't understand what this kid is going to do or why he is in charge.

"Don't go to the repair room?" Zheng Yucheng asked Xie Kai.(Read more @ hotmtlnovel.xyz)

Xie Kai shook his head.

"Director Zheng, let Xiaokai repair these machine tools?" The technicians were shocked.

"How can this work? We have been in contact with these machine tools for almost three years and dare not say that we fully understand. Many technical faults cannot be solved!" A thin technician in his fifties eagerly stopped. "Xiao Xie, this is not a joke, your dad can't help it..."

"Uncle Cao, don't worry, there is no big problem." Xie Kai said to the old technician. He knew that the other party was worried that he would cause bigger problems and the loss would be even greater.

"If you can't fix it well, let's see how your kid will explain it then!" Sun Jiaming appeared out of nowhere.

Xie Kai didn't even look at him, turned his head and said to Zheng Yucheng, "Chief, the internal structure of this thing is very complicated. During maintenance, you should not be disturbed. Sun Jiaming is here. I am nervous..."

"You..." Sun Jiaming burst into flames, "I told you that these equipment countries have spent millions of valuable foreign exchange. If you can't repair it, shooting a hundred times is not enough!"

Turning to Zheng Yucheng, he said, "Chief, this is the lifeblood of our Hongqi factory. Is it just that let him fool you?"

"You can fix it! Or let your son come, isn't your son also a technician here? Isn't he going to be promoted to engineer?" The old guy hit his muzzle, and if you don't get him down today, the father will do it in the future. Work is troublesome.

Sun Jiaming is not a good thing. He doesn't wear shoes for his father, which doesn't fit his style.

"Secretary Sun, you go out first!" Zheng Yucheng frowned and glanced at Xie Kai, and said to Sun Jiaming.

He was also upset, why did Sun Jiaming change his person today?

This is no alternative, a life-saving straw, otherwise what will Hongqi Machinery Factory do in the future?

Xie Kai's previous performance in the conference room made the military boss take a different look. Maybe he would be specially recruited by the university under the military.

I have said about Sun Jiaming's son twice in a row. Is it true?

If it's true...

Zheng Yucheng spoke to the assistants around him and asked them to find out whether some of what Xie Kai said was true.

Regardless of whether it is true or not, Xie Kai mentioned this one after another in front of the military chief, and he had to investigate.

"No one is bothering you now, can you do some work?" The attitude of the officer who started to have a good impression of Xie Kai became colder, not as good as before.

It is not a good thing for such a young child to be good at camping.

Xie Kai shrugged indifferently and looked in the direction of the maintenance room. His father was pushing a cart full of various tools.

"Xie, are you really here?" Cao Feng looked worried and nodded when he saw Xie Kai. "Let's beat you."

He hoped that they would help to make the consequences lighter.

"This feeling is good, Uncle Cao, please help you to remove all the PLC controllers and turn them on..." Xie Kai can't do it without doing it.

In the past, there were any problems in the factory. He had always been sitting and drinking tea and directing the newly graduated interns to work.

Under the command of Xie Kai, the control systems of three three-axis machining centers, two CNC milling machines and five CNC lathes were all removed and placed on a stainless steel workbench in front of one machining center.

"All of them are disassembled, and the parts inside are ready to be replaced. How about not disassembling?" Xie Kai said.

Everyone looked at Xie Jianguo, and Xie Jianguo nodded before starting to do it.

"Speed ​​sensor, proximity sensor..." Xie Kai said to Xie Jianguo after a quick inspection of the entire control system, "Dad, all I said are needed. Some of the ones that are not burned out are prone to problems and have to be replaced... …"

"What model do you want?" Xie Jianguo asked.

"Find one of the various models that are in stock, let's just remodel this one." Xie Kai is not afraid that his father can't accept it now.

For the various electronic parts from decades ago, he really couldn't figure out the model number, just looking at the things.

He doesn't care about the military leaders, he just wants to impress them and let the chief engineer of Xie Jianguo sit firmly.

The military leaders looked at Xie Kai without speaking, but only occasionally discussed in a low voice.

Zheng Yucheng invited military personnel to the office to wait, but was rejected.

Xie Kai brags in the conference room, the military leaders are going to fuck him.

Zheng Yucheng also stopped urging, and instead ordered people to bring some stools over, make tea for them, and let the military personnel drink tea while watching Xie Kai repair.

When Xie Jianguo saw his son violently unplug the chip on the PLC control system motherboard, he was nervous and sweated. Xie Kai used a multimeter to check all the electronic components on the motherboard. If they were broken, they would melt the tin with a soldering iron and then remove them. , The plugged in, directly pinch and unplug it, and throw it aside.

The actions were extremely rough, and the technicians were nervous and cautious when they placed the entire control system box on the workbench.

But when Xie Kai quickly soldered the diode on the motherboard of a control system, Xie Jianguo was relieved.

Afterwards, various parts were replaced. Most of the electronic parts are larger than those in the system. These are domestically produced. Xie Kai doesn't care about it. Observe it, discard the unusable ones, and send the ones that can be used directly to the motherboard. Get up.

The control system originally used the 8-bit 8048 chip developed by Intel in 1976. Xie Kai replaced it with Motorola's 16-bit 68000 microprocessor. He changed the entire control circuit structure beyond recognition.

The people next to me are frowning.

It took more than two hours, and Xie Kai just finished it at noon.

"Okay, you follow this and do the same for other motherboards. I will write out the instruction set required by the system first, otherwise it will be useless." After Xie Kai finished, he pushed the entire motherboard forward and let out a sigh of relief. , Said tiredly.

Let other people follow his instructions and are not afraid to make mistakes with various electronic components.

After that, he didn't care, took his father's pen, and quickly wrote the instruction set of machine language code on Xie Jianguo's work notebook.

Although these CNC machine tools are not the most advanced, they are relatively advanced. Xie Kai returned to Hongqi Machinery Factory after graduation. These old machines are still in normal use. They have been used for decades. The various programs are clear. Incomparable.

"Old Xie, are you sure this is your son?" Seeing that the PLC control system that was quickly repaired and was not even checked was thrown on the workbench, instead of writing the program without pause, Cao Feng asked Xie Jianguo in a daze. .
