(Don't ask for recommendation votes, brothers don't smash tickets, this is unacceptable!) The old brothers who came over left a trace in the comment area, so that the gourd could see your figure.) ）

Following into the workshop, from the gate to the inside of the workshop, there are three glass doors in succession, and there is a distance between each two doors, which are also separated by glass.

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

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

This is the first constant temperature dust-free precision machining workshop in China. Inside is installed from the United States CNC lathes, CNC milling machines and three-axis machining centers, the number is not much, but each one has been regarded as a baby, this is after the restoration of diplomatic relations between China and the United States, the Americans privately sold to China a batch of advanced CNC machine tools.

How much foreign exchange was spent, how much effort was spent, and those who were not involved were not able to figure it out. From the negotiations to the final equipment to China, it took four years.

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

It is not easy to come, and the domestic personnel naturally regard these high-end top processing equipment as the ancestors, for fear that the ancestors will not do it one day.

Therefore, such a workshop was specially built.

After a failure, it is often necessary to mobilize a bunch of technicians to meet and discuss, formulate various plans, and lead the approval of a series of processes before you can start troubleshooting.

Xie Kai knew very well that he used to laugh at his father's generation of technicians. As they get older, they understand why their parents were so careful with these devices.

The domestic technical force has advanced by leaps and bounds, and they are qualified not to care about the failure of the top equipment to strike.

Broken?

They have rich experience in repairing and repairing at will; even if they can't repair well, it doesn't matter, what can be produced in China can be replaced directly, and what can't be replaced will be bought! What the government has is money.

Not in this era, the CNC machine tools in the country, combined, are not even as many as a medium-sized mechanical processing factory in Xie Kai's era. Technicians have no experience, so they naturally have to be careful. Domestic production can't come out, foreign blockade can't buy it with money, let alone no money.

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

The equipment is broken, and it does not stop, the skilled workers are training, and the technicians are sad to discuss the maintenance plan around the machine tool that has been wiped spotless.

Seeing a group of people coming in, everyone's eyes were on them.

"Xie Gong, is there a solution?" a young technician wearing glasses asked Xie Jianguo eagerly, regardless of the bigwigs who came in.

Xie Jianguo nodded, "Prepare and dismantle the PLC control system." Prepare to replace the burned chips and electronic parts inside. ”

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

"Take it all apart?"

"Approved from above?"

"What should I do if I replace the internal chip, what should I do with the system program? What should I do if the chip does not match?"

Almost all the technicians gathered around and asked their doubts.

Knowing where the fault was, they didn't dare to disassemble and replace it because of technical problems.

The Americans gave the equipment only simple technical information, unless they had a thorough understanding of the inside of the PLC control system, who would dare to replace it?

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

"Don't worry, it's okay. Xie Kai said to these technicians, who were the youngest and more than ten years older than him, and said to Xie Jianguo instead, "Dad, lend me your maintenance tools, a full set." ”

A group of military bigwigs were staring at him, and Xie Jianguo couldn't say anything discouraged.

Immediately trotted to the maintenance room to get tools.

The technicians in the precision workshop all knew Xie Kai, and they didn't understand what this kid was going to do, why he was in charge.

"Don't you go to the maintenance room?" Zheng Yucheng asked Xie Kai.

Xie Kai shook his head.

"Director Zheng, let Xiao Kai 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, and many technical failures cannot be solved!" a thin technician in his fifties eagerly stopped. "Xiao Xie, this is not a joke, your father can't ...... it"

"Uncle Cao, don't worry, it's no big problem. Xie Kai said to the old technician, he knew that the other party was worried that he would cause a bigger problem and lose even more at that time.

"If people have that diamond, they will do this porcelain work. "I don't know when, Sun Jiadong came out.

Xie Kai didn't even look at him, turned his head and said to the major general, "Chief, the internal structure of this thing is sophisticated and complex, and when it is repaired, it can't be disturbed, Sun Jiadong is here, I am nervous ......."

"You ......" Sun Jiadong's anger came out, "You kid is nervous? Why can't I see it? I can tell you, these equipment countries have spent millions of precious foreign exchange, if you are completely destroyed, a hundred shots are not enough!"

"Can you fix you! Why don't you 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 himself with the muzzle of the gun, and if he didn't get him down today, his father's work would be troubled in the future.

Sun Jiadong is not a good thing, he doesn't wear small shoes for his father, which is not in line with his style.

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

He was also troubled, Sun Jiadong knew that he didn't deal with this kid, how good it was to stay honestly!

Xie Kai's previous performance in the conference room made the military bigwigs look at him differently, and it is estimated that he will soon be recruited by the university, which is subordinate to the military, and one of the requirements of this kid is to let his father be the chief engineer of the Hongqi Machinery Factory.

After talking twice in a row about Sun Jiadong's son, will the military be bad? If it is true, Sun Jiadong will be finished.

Sun Jiadong was reluctant to leave, but the major general said to the middle-aged officer next to him who had been showing strong interest in Xie Kai, "After you come down, you will personally go and check what Comrade Xiao Xie said." ”

The attitude of defending Xie Kai is very obvious.

Sun Jiadong's heart was cold, and he immediately left with a look of hatred.

"Now that no one bothers you, you can get to work?" The Major General's attitude towards Xie Kai was not as good as before.

It's not a good thing that such a young child is good at drilling.

Xie Kai shrugged his shoulders indifferently and looked in the direction of the maintenance room, where his father was pushing a small cart full of various tools.

"Xiao Xie, are you really coming?" Cao Feng looked worried, seeing Xie Kai nodding, he was also helpless, "Let's give you a hand." ”

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

"This is a good feeling, Uncle Cao, please help remove the PLC controller, and then open it...... "Xie Kai can't do it if he can."

In the past, when there was a problem in the factory, he always sat on the side 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 dismantled and placed on a stainless steel workbench in front of a machining center.

"It's all taken apart, ready to replace the parts inside, how can you do it if you don't take it apart?" Xie Kai said.

Everyone looked at Xie Jianguo, Xie Jianguo nodded, and then started to move.

"Speed sensor, proximity sensor, ......" Xie Kai said to Xie Jianguo after quickly checking the entire control system, "Dad, I need all these things I said." Some of them didn't burn out, but they were prone to problems and had to be replaced......"

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

"Find one of the various models that are always available, let's just transform this one. Xie Kai is not afraid that his father will not be able to accept it now.

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

He didn't care about the military bigwigs, so he wanted to impress them and let his father, Xie Jianguo, the chief engineer, sit firmly.

The military bigwigs, looking at Xie Kai from the side, did not speak, only occasionally discussed in a whisper.

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

Xie Kai bragged in the conference room, and the military bigwigs were in trouble with him.

Zheng Yucheng no longer urged, but instead ordered someone to move some stools over, make tea for them, and let the military personnel drink tea while watching Xie Kai repair.

Xie Jianguo saw his son pull off the chip on the motherboard of the PLC control system roughly, and he was so nervous that cold sweat broke out, all the electronic parts on the motherboard, Xie Kai checked them with a multimeter, and if they were broken, they were removed after melting the tin with a soldering iron, and the ones that were inserted on it were directly pinched and pulled out and thrown aside.

The movements are extremely rough, in contrast to the nervousness and caution of the technicians when they even put the box of the entire control system on the workbench.

However, when Xie Kai quickly soldered the diodes on the motherboard of a control system, Xie Jianguo breathed a sigh of relief.

Subsequently, all kinds of parts were replaced, most of the electronic parts are larger than those in the system, these are domestic, Xie Kai doesn't care, observe, can't be used aside, can be used directly to the motherboard.

The control system originally used the 8-bit 8048 chip developed by Intel in 76, and Xie Kai replaced it with a 16-bit 68000 microprocessor from Motorola, and the entire control circuit structure was changed beyond recognition by him.

The people next to him were all worried.

It took more than two hours, and seeing that it was noon, Xie Kai was done.

"Okay, you guys do this, and do the other motherboards like this. I'll write out the set of instructions that the system needs first, otherwise it's useless. After Xie Kai finished it, he directly pushed the entire motherboard forward, exhaled, and said a little tiredly.

Let others follow his example, and he is not afraid to make mistakes with various electronic components.

Then, he didn't care, took his father's pen, and began to quickly write the instruction set of machine language code on Xie Jianguo's work notebook.

These CNC machine tools, although not the most advanced, relatively speaking, are relatively advanced, Xie Kai returned to Hongqi Machinery Factory after graduation, these old machines are still in normal use, have been used for decades, all kinds of procedures are very clear.

"Lao Xie, are you sure this is your son?" Looking at the PLC control system that was quickly repaired in front of him and had not even been checked on the workbench, and instead wrote the program without the slightest pause, Cao Feng asked Xie Jianguo, who was in a daze.
