Chapter 166 Five-Axis Machining Center
Production workshop.
Early in the morning, the workers were moving and installing equipment under the command of Liu Tao.
Liu Tao also did it himself. After more than an hour, the five-axis milling machining center was finally installed.
"Director, is this really a five-axis machining center?" Xie Jin couldn't help but said in shock.
He is an expert in the field of machine tools and was assigned to Panshan Machinery Factory.
Although he was shocked that Liu Tao was proficient in CNC machine tools and could manufacture CNC machine tools, he could understand his shock even if he had used three-axis machine tools before.
But now it is a five-axis milling machining center, which is definitely the most advanced machining center in the world.
Xie Jin knew that before China wanted to import three-axis CNC machine tools, they asked for $1 million, because the processing accuracy of three-axis CNC machine tools was already very good and began to be embargoed by the Batumi.
As for the four-axis CNC machine tools, the price of one unit is at least $5 million, and even they are not very willing to buy it, and they are losing a lot.
And you have to know that this price is more than double the international price.
Because the international four-axis machining center is very strictly regulated, everyone has to be very careful, for fear of being discovered and sanctioned.
Five-axis machining center, this is the most advanced in the world, you can't buy it even if you have money, even if the price is 10 million US dollars or 20 million US dollars, people will shake their heads when they hear it, saying that it is really impossible, no matter how much money is given.
Five-axis machining center, but it is used to manufacture the most complex and top-level parts.
Before, China relied on those national treasure-level ninth-level workers to manufacture these most complex and top-level parts.
But there are only a few ninth-level workers in the country, and the manual production efficiency is low. No matter how hard the ninth-level workers in the country work, it is difficult to manufacture these most complex and top-level parts on a large scale.
And now Liu Tao has quietly made a five-axis milling machining center.
"Well, it's not easy to make this thing!" Liu Tao nodded, "Professor Xie, I will teach you next, if you don't understand anything, just ask, and you will teach others later!"
Xie Jin is a professor of mechanical engineering and automation at Tsinghua University, and he studied at the Massachusetts Institute of Technology in the United States. After the founding of New China, he responded to the call of the country and returned to China to participate in national construction.
Xie Jin was a participant in the development of China's machine tool field. He was a designer of China's first CNC machine tool.
Later, he was sent to the Beidahuang labor reform farm to work, and was not able to return to Tsinghua University to continue teaching until 1976.
This time he left Tsinghua University and came to Panshan Machinery Factory because of CNC machine tools.
In terms of CNC machine tools, China is really blank, and there is a serious talent gap.
Xie Jin served as the leader of the CNC machine tool group and formed an expert group with several other university professors. Liu Tao handed over the relevant CNC machine tool knowledge to them, and they taught the technicians, not only teaching theoretical knowledge, but also teaching how to operate, and also responsible for manufacturing CNC machine tools.
Three days ago, they just successfully built the first CNC machine tool.
Although it seems rough and simple in terms of the control system, it is a good start.
The reason why Liu Tao judged that even if he provided technology, the machine tool factory could not manufacture it was because Xie Jin and others provided the basis for his judgment.
Liu Tao took out a titanium alloy blade. This is a cast blade, but it still needs high-precision processing.
Put the titanium alloy blade material in it, fix the front and back ends, then click the screen, select the set program, and press start.
Suddenly, the five-axis machining center began processing.
On the screen, you can see the processing surface, as well as the corresponding coordinates and data.
Liu Tao explained.
When the blade was taken out after processing, Liu Tao took out the titanium alloy blade, and Xie Jin and others couldn't help but marvel.
This efficiency is far beyond the meticulous craftsmanship of the ninth-level workers.
Explaining one by one and answering the questions of Xie Jin and others, Liu Tao said: "Next, you will produce tank engine blades, and this aspect will be handed over to you."
"The information of the five-axis machining center will be given to you later."
The identities of these people are kept confidential, but it is not so easy to go abroad, and it is even less likely to be approached by spies.
Participating in the research of CNC machine tools, each one is carefully selected and signed a confidentiality agreement.
Even if they leave Panshan Machinery Factory in the future, they will often be followed by guards.
"Director, I have a question. Is this chip imported or produced by ourselves?" Xie Jin asked.
"Domestic." Liu Tao smiled, "This is produced by our Panshan Machinery Factory. We have all the technology."
The chip of the CNC machine tool is the "Loongson 1" chip named by Liu Tao. Its performance is the same as the 68000 chip. The 68000 chip was launched by Motorola. It is a CISC structure. After its launch in 1979, it was used in the earliest Apple computers and other devices. It has 32-bit internal registers, but can only transmit data on a 16-bit data bus. The processor can access 16 times the Intel 8088 in 1PC.
Liu Tao has a more advanced chip with far better performance than the "Loongson 1" chip.
But he didn't take it out because the chip performance is too advanced, too shocking, and too incredible.
Even the "Loongson 1" chip, because the manufacturing process is not up to standard and the materials are not in line, many domestic control components such as sensors cannot be compared with the world's first-class ones. Although they are made, the pass rate is very low and the cost is quite high.
The 'Loongson 1' produced by Panshan Machinery Factory can only meet its own use.
And such a 'Loongson 1' chip as the core processor of the CNC system is enough for a short time.
When the 'Loongson 1' chip technology matures and all aspects are improved, it can be mass-produced, and then the 'Loongson 2' chip can be produced.
Xie Jin was amazed. He didn't expect that the technology of Panshan Machinery Factory was higher than he imagined.
Xie Jin also knew something about chip development. After all, machinery and automation are often inseparable from semiconductors.
Since semiconductor technology was included in the important national scientific and technological projects in 1956, China has begun a long semiconductor national battle. In 1960, the Semiconductor Institute of Huazhong University of Science and Technology and the Semiconductor Institute of Hebei Province were officially established, which marked the initial establishment of China's semiconductor industrial system.
However, when countries around the world were accumulating strength to develop science and technology, China showed a sense of powerlessness before the start of this technological war. Under the pressure of the international community, advanced technologies such as integrated circuits cut off China's technical exchanges with the international community. Furthermore, the ten-year special period also severely damaged the semiconductor industry. At that time, the streets were filled with exaggerated slogans: Any old lady on the street can make semiconductors by pulling a stove in the alley.
The speed of technological change is very rapid, and China has begun to lag behind.
When the reform and opening up began, China's semiconductors were far behind the world.
But he did not expect that Panshan Machinery Factory, located in the deep mountains and old forests, could develop world-class chips. This is simply incredible.
Although he has been in Panshan Machinery Factory for more than a month, Xie Jin feels that Panshan Machinery Factory seems to be shrouded in a layer of fog, which seems mysterious.
