"The problem of the cutter does not care about the intensive reading of the material and the cutter head, in fact, the two are one, and the problem of the material is solved, and the problem of the intensive reading of the cutter head should also be solved."

Lin Kaihe pondered for a while, and said softly, the current technology of machine tools we master, in addition to CNC technology, is the gap in metal cutting technology, it is difficult to meet the needs of production technology, and relative to CNC technology, the easiest to improve, has a significant effect is to improve the material of the tool.

Li Jian deeply agreed with Lin Kaihe's words, the material of the tool is the most critical, hardness, toughness, impact resistance and other properties determine the effect and life of the knife, and it is not so easy to find the right material.

Wafer cutting and liquid crystal cutting, for the demand for CNC machine tools, is indispensable, the current precision requirements for the night screen is not so high, the domestic cutting machine tool is enough to meet the cutting process of one inch and two inches, but with the development of liquid crystal, it is bound to have higher requirements for the cutting of the intensive reading, especially after the further development of the material of the LCD panel, the requirements for the cutting process will only get higher and higher.

The cutting of wafers is the top priority, which is equivalent to the last step of the long march, if this step cannot be taken, then the wafer factory has no value in existence.

Li Jian also has relevant information on the key components of CNC machine tools, but like wafer factories, lithography machines and other technologies, there is no technology and no means to realize the technology.

To manufacture high-precision machine tools, we must first have a high-precision machine tool for the production of machine tool accessories, otherwise the production of parts and components itself can not meet the accuracy requirements. Even if a part is only a little bit different, hundreds or thousands of parts are assembled, and the difference may be hundreds or thousands of threads. It can even be said that this machine tool is scrapped directly.

And these are only the requirements of precision, CNC machine tools in addition to the mechanical part, or to have a high-precision control system, this part is the integrated circuit and control system needs to solve, the current domestic, is not able to solve.

Li Jian understands this truth, so he wants to solve this problem this time.

"Knives. I have an experimental system here, and you can take it and experiment and see if it works. It is best to contact the engineers of the machinery factory to make a finished product test test, after all, they have more applications for tools and have more experience. ”

Li Jian casually pulled over a piece of paper. A set of processes is written on it. This is one of the process processes of the tool materials he turned out of his mind, and the hardness and toughness of this material have actually been tested by the market countless times, but Li Jian can only say to Lin Kaihe that these are just experimental systems, because he can't say that the materials have been tested countless times.

Lin Kaihe's eyes were glowing with excitement, he had actually been waiting for Li Jian to come up with some information, or some material ratios. Because he has already summed it up, as long as it is something that Li Jian has taken out. That's a good thing, basically you don't need to test it, you know that at least it's the world's first-class today.

Especially when he saw the process flow that Li Jian took out, it was clearly an improvement on No. 78 steel, the main material of the tool, but when he looked down, he was a little confused.

Because after Li Jian finished writing about the improvement process of No. 78 steel, he wrote some other things below, and this row of letters and symbols represents another metal material, or another alloy to be exact.

Could it be that Li Jian wants to experiment with two kinds of tool materials at one time, but the market for knives itself is not large, and we are limited in our own use, so it is necessary to make two kinds of tool materials at one time?

"Dong Li, do you want to get involved in the machine tool industry next?"

"No, we are engaged in our own tools, because the next wafer factory and LCD factory need high-precision tools for fine cutting, a little bit of gap, will also affect the yield of our products, and the impact of CNC machine tools on cutting, excluding the error of the machine tool itself, the most critical part, is the tool."

"Machine tools are one-time purchase equipment, properly maintained, can be used for decades, but tools are consumables, we master the materials of the tools, our own production of tools, can reduce costs at the same time, more according to the needs of production, adjust the shape of our tools or other conditions, better cope with production."

"As for these two materials, the top is the body of the tool, and the bottom is the coated material, and the two materials must be combined to meet the requirements in terms of toughness, hardness, impact resistance, etc."

After Li Jian finished speaking, Lin Kaihe had already picked up the piece of paper written by Li Jian and began to look at it, these two materials turned out to be the relationship between the main body and the coating, from the perspective of the main materials, they were completely two optimized alloys with close main components, he couldn't imagine that the two could be plated together, in that case, why not directly use the form of alloy, use the second material as the cutter head, and the first material as the blade.

"I know you're thinking, why not use one to make the blade and the other to make the head, this is because only this kind of matching ratio can better exert the toughness and impact resistance of the first material, without affecting the hardness and cutting ability of the second material..."

Li Jian, like a teacher, explained the pros and cons of the two materials to Lin Kaihe, Lin Kaihe was like a primary school student, listening to Li Jian's explanation, where he was taking notes, for fear that there would be any missing content in Li Jian's explanation.

And his heart, is even more excited, he is not a material scientist, in fact, just an engineer in the machinery factory, is no stranger to machine tools, all kinds of machine tools in Shengli Machinery Factory, he has personally operated, but some familiar, some unfamiliar differences, what impressed him the most, is that these machine tool manufacturers are different, the requirements of the operation level are different, the precision and processing direction are different, but the only common point is backwardness.

Compared with the backwardness of the international level, there are so many excellent technicians, who rely on their own work experience to make up for the unstable performance of machine tools.

As an engineer, he has also been to other machinery factories in China to visit countless times, every time he goes, he sees the factories ready, the scenery and the beautiful side, but when he visits the workshop, he still sees a similar situation with Shengli Machinery Factory, and even most of the factories are not as good as Shengli Machinery Factory, their machine tool history is longer than those grandfather machine tools of Shengli, and various conditions are worse.

He once dreamed of the reform of the domestic machine tool industry, but knew that this can only be a dream, when the international general use of CNC machine tools, our country wants to buy CNC chips but can not get, they firmly control the sales of CNC chips, resolutely will not sell a little bit to the country, and the transformation of the mechanical part of the machine tool, without high-precision CNC machine tools to process, it is impossible to complete.

As for the material transformation of the mechanical part of the machine tool itself, instead of the key part, but the difficulty of the transformation is also not small, because the cumulative experiment that the material reform needs to do, it will be difficult to count, there is no factory in China, there is enough scientific research team to undertake this heavy task, and there are many aspects of the domestic poor and white, and there is no effective scientific and technological research organized from the national level, so it is impossible to carry out the technical reform of machine tools.

He listened to Li Jian ask about the machine tool when he came in, and he had such a fantasy in his heart, Li Jian was able to come up with the technology to change the status quo of China's machine tools, but he also knew that such technology was unrealistic.

But what he didn't expect was that Li Jian actually started from the simplest place and took out the process of material reform of the tool with the greatest impact of material reform, as long as Li Jian's things were verified to be correct, they could be completely industrially produced, which was the fastest way to achieve results.

But this is still far from enough for his dream of machine tools, he wants more,

"Li Dong, the problem of the cutter has been solved, the track, the motor, and the bearing ......"

Lin Kaihe was about to disassemble all the components of the machine tool in one breath, and his purpose Li Jian could see it at a glance, and wanted Li Jian to improve all the parts of the machine tool, but Li Jian knew that these were not achieved overnight, and these needed to be accumulated little by little.

And the basis of these accumulations, the most important prerequisite is to buy back a CNC machine tool, that is, the legendary machine tool, and use it to make tools, so as to achieve step-by-step improvement, otherwise every time a product is produced, it needs to be taken abroad to be processed, and then taken back to assemble.

"I've already thought about these things, but there is no suitable way yet, you don't need to worry, when I come back from Japan this time, I hope that it can be solved at once."

Li Jian picked up the notebook in front of him, Lin Kaihe knew that this was Li Jian and had to think about other problems, so he hurriedly said goodbye and left, although it was not solved, but he knew that since Li Jian said that it was possible to solve it after returning from Japan, it was really possible to solve it.

He didn't know, when he left, Li Jian had already started to write and draw in the notebook, what Li Jian wanted to do was to work like his reform of the cordless phone at that time, and replace the chips in the CNC machine tools as control terminals with the chips that can be produced in China.

But he also knows that the possibility of success of such a work is close to zero, not that it cannot be achieved, but if Li Jian really achieves it, the number of low-level chips needed is probably a huge number, and the cost and volume of this number, as well as other project parameters, as well as the complexity of control, will far exceed expectations, and it is not as suitable as buying foreign advanced control chips for direct production.
