"Nine-axis five-linked linkage? Isn't this several levels higher than the five-axis linkage?" The old man's eyes suddenly emitted light.

Yun Fei was still modest at the beginning!

For the old man who doesn’t know how to know CNC machining centers, Jiuyi Heavy Industry has gone from the initial two-axis CNC lathe to the three-axis two-linked CNC milling machine, then the three-axis three-linked machining center, and the four-axis four-linked machining center... they all rise one step by step. The nine-axis five-linked linkage has four more motion axes than the five-axis five-linked linkage!

If this is not advanced enough, what can be considered advanced?

"Old man, this cannot be understood in this way. It is not wrong to use the nine-axis five-axis linkage, but this is just a concept machine, and it is just for testing. In fact, many of the movements here are useless work. There is no problem in machining the wings of the aircraft and the five-axis linkage machining center. If conditions do not allow, use a gantry-type three-axis machining center and combined with tooling. In addition to more processes and worse position, it can also be processed..." Sun Lin explained to the old man with a wry smile.

"Is this not mass-produced?" The old man was a little confused.

Isn't this a joke for him?

"This is not. It's just that the control here is not a CNC system, but three different systems control different parts, and then integrated control is carried out through the powerful supercomputer of our research institute. In other words, this program is read through the supercomputer and then fed back to the control system..." Sun Lin's explanation made everyone dizzy. This is too complicated.

"Is there no way you can control it with just one CNC system?" The old man who didn't know his name was still asking a question. Since he could use a computer to perform segmented control, he could completely transfer it to the CNC system.

"This is the biggest problem. Our own CNC system is relatively barely controlling the five-axis linkage, and there are often delays, which leads to the problem of degradation of machining accuracy. To produce such equipment, we must first have a CNC system that can control nine motion axes. At present, Germany only has such a system in the whole world. The United States and Japan may have it, but I have never heard of it. Five-axis and five-linked equipment can fully realize the precision machining of most parts, and more axes are basically useless..." CNC machining center, five-axis and five-linked linkage are basically the top-notch.

It is not that the more motion axes, the more advanced it is.

If there are many motion axes, it is almost something developed to produce a specific product. For example, in the original world of Yunfei, Huaqing University has developed a nine-axis five-linked machining center for processing propellers. There are several spindle heads in total. Each spindle head processes a blade...

There is no problem with processing propellers that thing, but it is not possible to use it to process anything else.

These are very useless technical research directions.

Of course, it does not mean that the five-axis and five-linking in the CNC machining center is the most top-notch, and there are more advanced things. That is, the ultimate direction of CNC machine tools - industrial robots! This industrial robot is not the most common type of robot that can only make simple movements in those automobile production lines!

Due to time issues, everyone did not worry too much about it.

The 91st Research Institute said that they had no choice. Who can guarantee that they could provide a supporting control system? They had the best computer experts in China and the Soviet Union. What could they do?

As for who is the top expert in the Soviet Union?

Isn't this a joke? If Tanalia and Visarione Lovich were not the top experts from the former Soviet Union, they might be in charge of research on the one hand in the Jiuyi Institute? They are not the top experts. How could the Jiuyi Institute achieve such results?

Even if they are not, as long as they have these achievements, they will become the top experts. In China, such things are too normal.

"A machine of such a small value is more than 10 million?" The old man obviously did not expect that the five-axis linkage machining center provided by Jiuyi Heavy Industry to Factory 132 and Northern Heavy Industry. Although it looks very large outside, it is not as large as those gantry machining centers!

Yun Fei is clearly a cheating country's money.

"Old man, this is the five-axis machining center. The spindle can swing forward and backward, and next to it is the fourth axis, which is the motion axis responsible for rotating the workpiece. The circular public workbench below is responsible for moving the front and backwards..." Yunfei has no choice for the price of the five-axis thing. "The price of this equipment is not the high price of the equipment itself. But the high price of this series. Old man, you can see the processing scenario and you can understand why this price is so high. If it is so common like a three-axis machining center, ordinary companies can also produce it, and this thing is not worth much. Originally, when we could not produce four-axis in our country, a four-axis machining center dared to sell us two million US dollars! How much is it now? After we can produce it, the price is only four million yuan, and the US dollar is less than five hundred thousand yuan..."

Yunfei's meaning is very obvious. What we sell is not equipment, technology, production capacity, market opportunities, and even it can rise to national survival opportunities.

Who said that there is no such thing? Many strategic equipment cannot be mass-produced?

Before there is no four-axis machining center, China's annual capacity for Dongfeng 31 production will not exceed five! The Russians are the most obvious. With such a huge industrial foundation, the ability to produce Poplar-MD missiles will not exceed twenty each year. This is because China's CNC machine tools in their country are still behind...

Many parts with super high accuracy requirements, if they are only produced manually, the efficiency can be completely imagined. This is like a carriage and a train comparing transportation capacity.

"This machine is the blades of Xinkaixing Impeller Factory. The spindle speed is 24,000 rpm and the movement speed is 85 meters per minute. It is considered a high-speed machining center. The machining efficiency is about 40% higher than the four-axis, and the accuracy is 20% higher..." Sun Lin pointed to a five-axis machining center that is processing gas engine blades. This thing is processed by five-axis, which is much more efficient than the four-axis machining center.

This machining center is different from the large gantry machining center next to it. The machining parts rotate faster. The spindle does not swing left and right, but keeps moving up and down in response to the flip of the parts, always keeping the distance between the apex of the ball knife on the spindle and the parts to avoid the occurrence of knife collision or over-cut imagination...
