"Mr. Cao, don't worry, this has been simulated and run many times!" Liang Qiang was also very nervous.

If CNC machine tools proved that there is no problem this time, in the end, they will no longer need a CNC system that relies on the program of drilling holes on paper tapes to control it. With CNC system, the base can produce CNC machine tools themselves!

"Yes, although this transformation is mainly part of the CNC system, I believe you, and I believe more of Director Xiao Liu. He took action personally. If there are any problems, can he still be the magical Master Xiao Liu?" Yu Jianguo said with a smile.

They know more than anyone else how much energy Liu Yijiu has put into this CNC machining center. He is also talking about the problems of hydraulic workstations, pneumatic workstations, and even tool handle design. He also discusses any difficulties together.

"Okay, there is no need to check again. Let the comrades around you get a little bit out of the way. Although we have tried many times when changing the knife, there will be no knife drop, but we have to make sure that if..."... Liu Yijiu was speechless when he heard this.

I have conducted a lot of experiments before, but there is no problem. Now I need to conduct the final test, but I am afraid of it.

"If it doesn't work, we will continue to study. If it works, we will continue to study. So, whether it succeeds or not, it is not a problem for us, and it cannot stop us from moving forward. Let's start..." Liu Yijiu said, and the others didn't say anything else.

"Don't worry, choose a single-segment operation first, so that we can better discover problems."

As he finished speaking, Jia Ling, who was responsible for machine tool operation, determined the aluminum alloy blocks used for trial processing on the machine tool workbench again, and then walked to the side. Rotate the plc operation panel to a direction parallel to the machine tool, and leaned on his own. Select the knob to a single section to execute, and then pressed the green start button above.

The CNC machine tool that was originally motionless began to move after Jia Ling pressed the start button. The workbench began to move, and the tool magazine next to the machine spindle box also began to rotate. The spindle rose a little before stopping. When the tool magazine was originally placed horizontally, when it was rotated to the tool change position, it slowly turned down under the control of hydraulic and electronic signals, and then became parallel to the spindle hole.

The robotic arm, which was originally located in the middle of the spindle and tool magazine, quickly moved downward under the control of air pressure and electronic signals. When it reached the tool change position, it rotated directly ninety degrees, just so that it could get stuck on the tool holder.

"Bang!" The air pressure in the tool magazine changed, and the tool magazine that was originally holding the tool suddenly released its grip.

With Jia Ling's operation, the robot's movements were very slow. Without a shield, it was also the first time that the actual tool change was actually done in the overall operation, which made everyone very nervous. Originally, the tool change movement could be solved with just one code. But now they have compiled a separate program to operate.

In terms of CNC systems, for future export issues, Liu Yijiu did not modify the international iso standard code. These are common and can only be exported later.

After the robot holding the handle of the knife moved and rotated 180° bit by bit. It rose quickly, and after hearing a snap, the robot returned to its original position...

After the tool change work is completed, the spindle begins to descend and rotates in the process.

"Reduce the speed. Use 60% gear!" Liu Yijiu was constantly commanding according to the situation, and Jia Ling was operating quickly under his command. The basic operation of CNC machine tools is not difficult. The most important thing is to be familiar with the functions of the entire control system.

At the same time, the most important operation is to clamp the parts on the workbench and find the right part.

This is a necessary job to establish a coordinate system for a machine tool. This is different from ordinary milling machines. Ordinary milling machines can be processed while measuring, and it is very easy. CNC machine tools can also do this, but they cannot guarantee accuracy.

In order to let the machine tool know where the position is the origin and where the processing is, it must be set and input in the CNC system. In this way, the machine tool has a reference and can be measured by the grating scale to process it strictly according to the parameters set by the program.

"Since there is no problem, let the machine tool execute automatically..." Liu Yijiu said that he was not nervous, which was impossible.

After all, there are too many things to carry on this.

Complex parts, high-precision parts, and the efficiency and reliability of CNC machine tools are much easier to complete than experienced technical workers.

As the programs continue to incite on display screens that are only the size of a palm, all parts of the machine tool are starting to move fast or slow, and the spindle speed is also constantly changing fast or slow.

These are controlled in the machine tool program.

After the first knife was finished processing, the movement stopped, and the entire machine tool did not move before changing the tool.

The original square parts on the machine tool have begun to become an ellipse under program control, with a simple shape with an arc on it and a circular hole in the middle. Without professional design software, it is not very easy to process some complex three-dimensional space curved surfaces like propellers.

Programming alone is a very difficult thing.

This requires the introduction of macro programs. The most basic programs have not been completed. Liu Yijiu just asked Cao Zhijiang and others to study them, but it is not used now.

Moreover, the CNC machine tools that they introduced at the beginning with the paper tape drilling control system did not have this function at all.

"Master, or a single-stage operation?" Jia Ling stood in front of the control panel, turned her head and asked Liu Yijiu.

Liu Yijiu thought about it, shook his head, and let himself run automatically.

Now is the most critical place to detect their control systems, tool changing mechanisms, hydraulic workstations, and pneumatic work.

The tools on the spindle are compared with the tools in the tool magazine.

Although I have done experiments and there is no problem, now it is all concentrated on this machine tool, and only one t representing the tool and data representing the number of tools is used to control it. This is the first time. After all, the most important technology in a CNC machine tool is the control system.

The tool change is to detect whether the integration of each system is met, whether it meets the design requirements, whether it can complete strict coordination, electronic components, mechanical components, pneumatic components, hydraulic workstations, etc. all work together.

A simple action combines all the essence of the entire machine tool.

Jia Ling cong's white fingers were trembling and unable to press them down for a long time. Luo Tong, who was on the side, was a little anxious, "As sooner or later, there must be such a thing. The ugly daughter-in-law must meet her parents-in-law. If her parents-in-law don't like her, she is planning..."

After saying that, he pointed at the green button and stabbed it hard...

Everyone held their breath and stared at the movements of the machine.

As he pressed down, the tools that were already in place in the tool magazine slowly turned into a vertical workbench again.

The manipulator, which was originally standing in the middle, bounced down instantly and then moved quickly, just stuck in the V-ring groove on the hilt of the knife. With a bang, the manipulator holding the two knives moved down quickly. Everyone's hearts were in their throats, and it was time to see this step!

The robot grabbed the two knives and rotated them 180° again. When he reached the position, he pulled up suddenly. The shank replaced from the spindle accurately entered the knife sleeve; and the shank replaced from the knife sleeve accurately entered the spindle hole.

With another bang sound, the tools inside the knife sleeve and the tools on the spindle were simply pulled by the air pressure.

The robot loosens the handle, rotates 90°, returns to its original position, and does not move!

"It's done! Finally it's done! From now on, we will have more advanced CNC machine tools than abroad!" Although this process is long to describe, it is actually only more than two seconds. After completing this process, others cheered without caring about whether the program was over and whether the processing was completed.

Yu Jianguo's eyes were filled with tears.

The first CNC milling machine in the Republic was born in 1959 at the Capital No. 1 Machinery Factory, or CNC engraving machine is more suitable because it can only be used to engrave words, but it was eventually buried by history. However, if this one was not persisted, China still failed in the end.

At that time, there was a lack of understanding of the characteristics and development conditions of CNC machine tools. When the personnel quality was poor, the foundation was weak, and the supporting facilities were not up and down, they rushed up and down, and finally stopped due to poor performance and could not be used for production.

It just so happened that Yu Jianguo was the person in the project that year.

"Let me down quickly! I'm dizzy, I'm dizzy..." Liu Yijiu didn't expect that Qin Huaibao and Luo Tong started, and other technical workers also started to cheer and lifted Liu Yijiu up, and in the workshop he held him up and threw him up!

Liu Yijiu was helpless.

At this time, it was not the time when domestic CNC machine tools had never been able to make breakthroughs. If they waited until then, how crazy would these guys be?

"This kid should probably study the structure of his brain..." Long Yaohua, who followed Wang Shunyi and Zheng Hao to find Liu Yijiu, said with a smile after knowing what was going on.

If Liu Yijiu heard this, he would probably run away...

"After the CNC machining center they studied were successful, many of our projects would accelerate a lot. The current new equipment has very high requirements for processing technology. The CNC machine tools that the Americans promised to us have not been in place..." Wang Shunyi sighed.

His face was also full of smiles.

"He did not disappoint his father's expectations of him..." Li Yunlong said lightly.

They did not understand the impact of CNC machine tools on advanced equipment manufacturing. They were shocked until they saw that CNC machine tools were constantly processing parts into shapes of straight lines or arcs without anyone operating them!

From then on, the Chinese have their own CNC machine tools. (To be continued...)
