Intelligent Industrial Empire

"Nine-axis five-axis linkage? Isn't this several levels higher than five-axis linkage?" The old man's eyes suddenly lighted up.

Yun Fei was still humble at first!

For the old man who doesn’t know the CNC machining center, Jiuyi Heavy Industry starts with a two-axis CNC lathe to a three-axis two-link CNC milling machine, then a three-axis three-link machining center, a four-axis four-link machining center... It rises level by level. The nine-axis five-linkage has four more motion axes than the five-axis five-linkage!

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

"Master, can this be understood like this. This is a nine-axis five-linkage. It is not wrong, but this is only a concept machine, and it is only used for experimentation. In fact, many of the movements in it are useless work to process the airplane wings. , A five-axis machining center is no problem. If conditions do not permit, use a gantry-type three-axis machining center with tooling. In addition to more processes and poorer position, it can also be processed..." Sun Lin smiled bitterly. The old man explained.

"Can't this be mass produced?" The old man was a little puzzled.

Isn't this a joke on his old man?

"This is not. It's just that the control inside is not a set of numerical control systems, but three sets of different systems control different parts, and then integrated control through our research institute's powerful supercomputer, that is, this The programs and everything are read through the supercomputer and then fed back to the control system..." Sun Lin's explanation made everyone dizzy.This is too complicated.

"Don't you have a way to control it with just one CNC system?" The old man who didn't know the name was still asking.Since the computer can be used for segment control, it can be transferred to the CNC system.

"This is the biggest problem. Our own numerical control system is relatively reluctant to control the five-axis linkage, and there is often a delay, which causes the problem of reduced processing accuracy. To produce this kind of equipment, you must first have a numerical control that can control nine motion axes. System. At present, only Germany has such a system in the entire world. The United States and Japan may have such a system, but they have not heard of it. The five-axis and five-linked equipment can already realize the precision machining of most parts and more axes. Basically it is useless..." The CNC machining center, five-axis five-linkage is basically the top class.

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

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

There is no problem with that thing processing propellers, but it can't be used for processing other things.

These are very tasteless technical research directions.

Of course, it is not to say that the five-axis and five-linkage in the CNC machining center is the top level, and there are more advanced things, which 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 on those automobile production lines!

Due to the time issue, everyone did not struggle too much with this.

The Jiuyi Research Institute said that they have no way. Who can guarantee that they can provide a supporting control system?People have the top computer experts in China and the Soviet Union, but they can’t help it. What can they do?

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

Is this a joke?Tanalia, Visaryonlovich, experts from the former Soviet Union, if they were not the top-notch, might they be in charge of one aspect of research in the September 1st Research Institute?They are not the top experts. How can the Jiuyi Research 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 and normal.

"Such a small machine is worth more than ten million?" The old man obviously did not expect that the five-axis machining center provided by Jiuyi Heavy Industry to the 132 Factory and Northern Heavy Industry. Although it looks very large on the outside, it has not yet. Those gantry machining centers are huge!

Yun Fei is clearly scamming the country's money.

"Master, this is a five-axis machining center. The main shaft can swing back and forth, and next to it is the fourth axis, which is the movement axis responsible for rotating the workpiece. The circular male table below is responsible for moving back and forth..." For the price of the shaft, Yunfei has no choice."The price of this equipment is not the high price of the equipment itself, but the high price of this series. Father, you can understand why this is sold at such a high price by looking at the processing scene. If it is like a three-axis machining center Generally, ordinary companies can also produce it, and this thing is worthless. Originally, when we were unable to produce four-axis in China, the Germans dared to sell us two million dollars for a four-axis machining center! How much is it now? After we can produce it, the price will be 4 million yuan, and the US dollar will be less than half a million..."

Yunfei's meaning is obvious. What we sell is not equipment, but technology, but production capacity and market opportunities.It can even rise to the country's chance of survival.

Why doesn't it mean that there is no such thing as mass production of many strategic equipment?

Before there was no four-axis machining center, China's annual production capacity of Dongfeng 31 is estimated to not exceed five!Lao Maozi is the most obvious. With such a huge industrial base, the annual production capacity of Poplar-MD missiles will not exceed 20. This is because their country's CNC machine tools are still behind in China...

Many parts require super high precision. If it is only produced by hand, the efficiency can be fully imagined.It's like comparing the transportation capacity of a carriage to a train.

"This machine is processing the blades of Xinkaixing Impeller Factory. The spindle speed is 24,000 revolutions per minute and the moving speed is 85 meters per minute. It can be regarded as a high-speed machining center. The processing efficiency is about 40% higher than that of the four-axis. Twenty percent high..." Sun Lin pointed to a five-axis machining center that was processing gas engine blades. This thing uses five-axis machining, which is much more efficient than a four-axis machining center.

This machining center is different from the large gantry machining center next to it. The processed parts rotate faster. The spindle does not swing from side to side, but instead moves up and down in conjunction with the turning of the parts, keeping the spindle at all times. The distance between the apex of the ball knife and the part is the same to avoid the phenomenon of hitting the knife or over-cutting imagination...

"This seems to be no different from the four-axis next to it?" The entourage who visited pointed out that this is a four-axis linkage machine tool.Although the rotating fourth axis can move up and down one after the other, and the hydraulic top at the back can also follow up synchronously, it is essentially a four-axis.

"At present, this equipment is testing the rotation positioning accuracy of the rotating shaft. The blade is completely processed by a four-axis machine tool, because this is just the simplest three-dimensional twisted surface. This batch of blades is to test our five-axis machining The reliability and processing accuracy of the center were specially mobilized from Xinkaixing Impeller Factory..." Sun Lin directly filtered out any bad intentions in these words.

The main function and main work of the test workshop is to experiment with these integrated machining centers. Not all equipment processing any parts can use all the functions.

"Wow..." When they saw the things being processed on three consecutive machines that were exactly the same as this impeller processing machine, many people were amazed!

These three processing centers are actually carving people's heads!And the soft display on the modeling programming computer next to it, this head is actually the head of the old man!

It's just against the sky.

"This is to test the processing capabilities of these machine tools. At the same time, our boss just used our machining center to carve the master's head in order to give the old man a gift..." Sun Lin's explanation immediately shocked everyone.

I have never heard of the use of machine tools to carve human heads!And now, they actually saw it with their own eyes.

The most difficult thing is not to carve out the shape.But human facial expressions are very vivid!

"This is processed by the latest aviation duralumin jointly developed by the material factory of Northern Heavy Industry and the material factory of the 132 factory. In order to obtain the test data, the three processing centers use different materials, which are the difficult-to-process material TC4 titanium alloy. The H62 brass with better processing performance and the aviation duralumin that has been processed here..." This is a gift Yunfei prepared for the old man.

When the old man inspected Huadu for the first time, Yunfei gave him an ordinary aluminum plate with very artistic characters carved with a processing center. This time, Yunfei simply used the processing center to engrave the old man's head!

"The most difficult part here is to process the facial contour part, because this part of the tool must constantly use the swing angle, so that it can meet the requirements of the model, and it will not be processed because the angle is not enough, and it will not be processed. Also due to the lack of angle, the phenomenon of overcutting occurred..." Few visitors were professional, so Sun Lin would naturally introduce the difficulty.

Then everyone follows his tips to see if things are really the case, and it is easy to understand why the five-axis is powerful.

The five axis is much stronger than most people think.Using this to sculpt a human head is just to test the function, not for anything else.Only the human head has a very complicated three-dimensional structure, can the function of the equipment be tested in all directions!
