Chapter 742, five-axis machine tools

Back at the research institute, Jiang Yan had not immediately started manufacturing tanks and other equipment.

Because before that, he still had to do a big project - build a five-axis CNC machine tool.

Five-axis linkage CNC machine tools are simply a manufacturing tool for flower growers. It can move in five directions and is dozens of times more efficient than ordinary machine tools when processing complex-shaped parts. With its super processing capabilities, it can achieve fast and precise processing of parts.

This is indispensable for the production of high-end equipment such as tanks. You must know that the various parts of the tank have complex shapes, and the processing efficiency of ordinary machine tools is too low to meet the demand. However, if there are five-axis linkage CNC machine tools, the processing difficulty will drop sharply, and the manufacturing of tank armor, gun barrels and other components can be easily completed, and the increase in production capacity will be huge.

Not only can military manufacturing develop rapidly, but the entire manufacturing industry will enter a new era of precision, automation, and numerical control.

The famous "Toshiba incident" in later generations can be said to be the most famous smuggling case of military-sensitive high-tech that caused the greatest harm to the security of Western countries during the Cold War so far. Its impact was huge.

Advanced CNC processing equipment is an important strategic material for any country! For a long time, the western industrialized countries headed by Yingjiang have been embargoing CNC machine tools to flower growers, fur bears and other socialist camps.

Later, Toshiba exported four TDP-70 and TDP-110 boring and milling machines to Mao Xiong. However, according to the information obtained by intelligence personnel, in fact, what Mao Xiong obtained was not these two machines, but four nine-axis machines. Five-linkage large-scale CNC propeller milling machine!

This set of machine tools can complete mathematical modeling and high-precision processing of complex curved surfaces through a complex and complete set of algorithms and precise control systems. It is very suitable for processing high-performance propellers required for nuclear submarines.

With this advanced CNC machining equipment, Mao Xiong Military Industry replaced its guns with cannons and quickly produced a large number of nuclear submarines with advanced technical performance. Even its naval construction process was greatly accelerated by the arrival of this batch of footbath chicken machine tools.

Thinking of this, Jiang Yan couldn't wait any longer.

He was determined to build a five-axis machine tool production line and use it to complete the processing tasks of core components.

Therefore, Jiang Yan summoned most of the scientific researchers in the institute, excluding the lithography machines, to the conference room.

"Comrades, I'm going to start a big project, but I need your help." Jiang Yan said solemnly.

Everyone became energetic and said quickly: "General Manager Jiang, please tell us that we will go all out for any project!"

Everyone was very excited when they heard that Jiang Yan was going to take him on a project.

"Since everyone is so passionate, I'll tell you the truth." Jiang Yan put on a mysterious expression. "This time, we are going to develop a five-axis linkage CNC machine tool!"

"Five-axis linkage CNC machine tool?"

"What is this?"

Everyone looked at each other, confused.

I saw some different looks on the faces of several old experts.

"Five-axis? Now there are three-axis CNC machine tools. What does he mean by five-axis?"

"Isn't the technical content too high? Can we make it?"

Everyone looked puzzled. Although they were novel about this new word, they were more confused.

Jiang Yan saw everyone's confusion and explained with a smile: "The five-axis linkage CNC machine tool sounds very high-end, but the principle is actually not difficult. It is to add two rotation axes to the three axes."

“Its biggest advantage is that it has extremely high processing efficiency, can achieve multi-axis compound motion, and can easily process complex-shaped parts.”

"If we can take the lead in developing it, it will be a huge boost to industrial development!"

After hearing this, everyone's faces were filled with shock.

"Here, five-axis linkage, this concept is too advanced!" A technician sighed, "Three-axis machine tools are still very rare, but he directly jumped to five-axis. How advanced is this!"

"General Engineer Jiang's ideas are so advanced that we really can't keep up." An old engineer said, shaking his head.

"But what does such a machine tool mean? Any complex-shaped parts can be processed!" "Yes, yes, airplanes, tanks, etc., why do they need so many processes?"

Everyone was talking and talking, and everyone was so excited that they danced and shouted.

But soon, they gradually calmed down again, with worried looks on their faces.

"But can we really make this thing? Is this technology too advanced for us? To achieve five-axis linkage, the control system alone is very complicated, and we people may not be able to play it. Turn around."

But if it succeeds, how fast will the industrialization process advance! What a contribution this must be! Everyone is entangled, full of longing for this project, but also deeply feeling powerless.

Jiang Yan saw their lack of confidence and encouraged: "Comrades, I understand your concerns. But as long as we work together and persevere, we will succeed! Besides, I am with you! Let's all work hard together. .

With Jiang Yan's encouragement, the five-axis machine tool project was in full swing at the institute.

Jiang Yan understood that the key to successfully developing a five-axis machine tool lies in the design of the control system. This determines the movement accuracy and repetitive positioning accuracy of the machine tool.

This is undoubtedly a big problem, and the most difficult one is the chip. The research on chips in his own factory is still gradually progressing. There is no other way, so Jiang Yan can only ask the big boss for help.

After the senior leader received Jiang Yan's call and listened to Jiang Yan's introduction, he thought for a while and agreed.

When Jiang Yan heard that the big leader agreed, he felt relieved. If he couldn't handle it himself, the country could still get some chips through other channels.

Less than a week later, twenty chips were in Jiang Yan's hands.

During this week, Jiang Yan and the others had already prepared the complete design drawings of the five-axis machine tool.

Jiang Yan took out the drawing and looked at it carefully, comparing it to the chip in his hand.

"Well, the chip performance this time is enough to complete all control functions."

He nodded with satisfaction and began to mark the control system part of the design drawing.

Jiang Yan made precise calculations for the parameters of the new chip.

He marked the chip connections, the layout of the logic circuits, and the framework of the programming code in detail on the design drawings.

These are simplified versions of modern five-axis machine tool control systems. After being simplified, they can be implemented with the help of existing chips.

Then, Jiang Yan came to the laboratory to program and weld the chips he brought out. He used a delicate pen tip to draw circuit connections on the chip and set up the logic gates. Then solder a simple control circuit board.

"Okay, let's test it."

Jiang Yan connected the power supply and wrote a simple machine tool operation code.

The circuit board starts operating immediately and outputs various control signals according to the code instructions.

"Run normally, perfect!" With this control system, the most critical step in the manufacturing problem of five-axis machine tools has been solved.

Since rolling mills are producing various machine tools in large quantities these days, most of the required parts are readily available in stock.

Jiang Yan checked the design drawings of the five-axis machine tool and found that only a few key parts needed to be remanufactured.

In order to quickly obtain these customized parts, he assigned a group of senior workers to process them. After several days of non-stop work, all the parts have been processed.

At this time, all the components required for assembly were in place, and he began to lead the technicians to assemble the five-axis machine tool.
