After a short break, Jiang Yan organized everyone to devote themselves to the assembly of CNC machine tools.

Before Jiang Yan organized workers to start manufacturing parts on CNC machine tools, it was effortless for them to manufacture these parts, and soon, all the parts that Jiang Yan needed were sent from the workshop.

"Comrades, with the CNC system as a foundation, we can now start assembling CNC machines." Jiang Yan clapped his hands and said.

"Assemble it with a precise fit between the individual parts."

"In particular, it is necessary to carefully debug the connection between the CNC system and the mechanical structure, which is related to the accurate transmission of instructions."

"Understood, it must be strictly operated." Everyone responded in unison.

So, under the guidance of Jiang Yan, everyone began the assembly of CNC machine tools.

Several skilled workers first bolted the base and then installed the spindle support frame.

The students tightened the gears one by one to ensure that the components ran smoothly.

After a day's hard work, the silver-gray body of the machine has been assembled, exuding a cold metallic luster.

"Okay, the main body of the machine is assembled, and now we have to start installing the CNC system." Jiang Yan nodded with satisfaction.

He carefully removed the previously modified CNC actuator and installed it inside the machine with several engineers.

"Pay attention to the plugging and unplugging of the line connection, and don't make the wrong connection." Jiang Yan said as he carefully checked the wiring.

After debugging, the CNC system is finally accurately connected with the transmission system of the machine tool.

"Great, our first CNC machine has finally been assembled!"

Everyone hugged each other excitedly, tears welling up in their eyes.

"Comrades, we are only halfway done in our task, and we still need to carry out comprehensive debugging and testing."

Seeing everyone's excitement, Jiang Yan said with a smile.

In the following time, everyone began intensive debugging work.

Jiang Yan constantly writes a variety of complex processing programs to test the responsiveness of the CNC system.

In repeated tests, the performance indicators of CNC machine tools have gradually improved and tended to be perfected.

In the process of repeated testing, some mature processing programs were also tested by Jiang Yan, and these programs were not only recorded in a notebook, but also engraved on a batch of wheel paper urgently processed in other workshops, and wrote down the processing items, and handed them over to their secretaries for preservation.

"Next, we need to do some workpiece machining."

Just when everyone was immersed in the joy of success, Jiang Yan directly proposed to start working parts.

Naturally, this proposal was unanimously agreed upon by the big guys, but they started with the first part.

So, under the guidance of Jiang Yan, several workers set up a steel ingot, and after conducting a strength inspection, it was confirmed that it met the standard.

"The material is in place, ready to start processing!" Jiang Yan's voice resounded in the workshop.

Everyone held their breath, anxiety and restlessness filling the air.

This is a real challenge and test for the development of Huajia machine tools!

"Let's go!" Jiang Yan decisively pressed the start button.

Hearing only a soft sound, the CNC machine tool was running, the high-speed spindle began to process the material, and the sound of "buzzing" echoed in the workshop.

At the moment when the CNC machine tool was started, the workshop was silent, and everyone was staring at the steel ingot on the machine tool tightly, with a tense look on their faces.

However, the CNC system is running stably, precisely controlling the movement of the axes.

Under its "command", the machine automatically changes tools and begins to turn the surface of the material.

"Oh my God, this machine is really turning automatically, no one controls it, how does it do it?!" An old lathe worker looked at the CNC machine, shook his head and muttered incredulously.

"If it is really successful, then this machine is simply our pride!"

In this way, in the extremely tense atmosphere of the whole audience, the CNC machine tool carried out automatic processing for more than ten minutes.

"Processing is over!" Jiang Yan pressed the button to turn off the machine.

"Huh?! That's good?! ”

"How could this be just over ten minutes?"

"Machining a workpiece in more than ten minutes?! I don't believe it! ”

Seeing that the processing was done so quickly, some workers' eyes widened.

"I'll test it." Professor Wang took down the machined parts with gloves and began to test them with a ruler.

"Qualified" under the expectant gaze of everyone, and the two words spit out from the innermost part of Professor Wang.

At this time, Jiang Yan felt that the word "qualified" was so beautiful.

After everyone cheered, the second stage was started, then the third stage workpiece, until the fourth stage stopped.

The fourth-level workpiece is different from the previous three-level, and the fourth-level workpiece is also the watershed between junior and intermediate workers, and the parts he processes are more complex.

A technician said a little apprehensively, "Mr. Jiang, isn't it a bit risky for us to test the fourth-level artifact?"

"Yes, yes, we just assembled this machine, what if the test fails to damage the machine." Another technician spoke.

Jiang Yan smiled slightly, waved his hand and said, "Comrades, I understand your worries, but we must have an enterprising spirit.

"This machine tool is our self-developed CNC machine tool, according to the theory as long as there is a relevant program, any kind of workpiece can be made, and its processing accuracy will never be worse than that of the West. So we have to believe in ourselves."

"I believe that through rigorous debugging and extreme testing, his performance can be brought into full play."

"But the fourth-level workpiece is very complex and delicate, and it is difficult for ordinary workers to complete it, can this machine tool do it?" A tall male student asked suspiciously.

"Young people, there are some things that you won't know if you don't try them boldly." The gray-haired Professor Wu spoke, "I agree with Xiao Jiang's proposal, we should let this machine tool play its maximum potential, this is not only a trust in us, but also an affirmation of our research and development results." ”

Through exchanges in the past few days, he knows that Jiang Yan is very sure of what he does. Since he said yes, then he must be able to.

"Since Mr. Jiang is so sure, old man, I will accompany you crazy once, then I also agree to test precision workpieces to see how far my country's machine tools can go!"

"Good! Now that everyone agrees, let's start the processing test of the fourth-level workpiece!" Jiang Yan clapped his hands and said with confidence.

After everyone agreed, a steel billet was placed on top of the CNC machine, and under the eyes of everyone, Jiang Yan pressed the button, and the machine began to rotate.

All eyes of everyone looked at the parts being processed, and only the sound of machine processing was heard in the entire experimental workshop.

After about ten minutes, the machine stopped, and a machined part appeared on the machine.

"That's good," said an old worker, looking at the machined parts.

Usually, it takes them an hour to process a fourth-level workpiece quickly, and it will be done in more than ten minutes.

"Just look at it." Suddenly, a voice rang out.

Suddenly, everyone rushed to the machine like a frightened rabbit.

"Let me see!"

"I'll check!"

Everyone scrambled to get the piece of workpiece.

Finally, a master carefully picked up the finished precision parts.

"How?" Countless trembling hands stretched out from the crowd, eager to pick up the parts.

"Give me the micrometer!"

The old master shouted with slightly trembling fingers.

Then someone handed me a micrometer.

He couldn't wait to take the measurements.

After a minute, his eyes widened, and he said in a tone that was on the verge of collapse:

"No way, this can't be!! This accuracy ...... This accuracy is within the standard error range!! ”

"What?!"

"Really?!"

The scene exploded instantly.

Everyone crowded to look at the small metal part, and then took turns to step forward and repeatedly test it with various instruments, for fear of detecting any flaws.

But no matter how you check it, the results are shockingly accurate!

"I don't believe it!"

"This must be a dream!"

For a moment, everyone was deeply shocked, and their faces were distorted with excitement.

At this moment, they realized for the first time that the machine tool of the flower grower could also achieve such a high manufacturing level!
