Sufficient electricity is input into the industrial park, and a large number of mechanical and electrical workers have begun to enter their posts, all in place, producing the most needed high-precision snipers at present, and striving to increase production!

More advanced 3D+ industrial printers, fully automatic CNC industrial machine tools, and super pharmaceutical factories are assembled in machinery factories and electronics factories, which consume a lot of energy. Pen % fun % Pavilion www.biquge.info

These things are very large, although the host of the 3D+ printer is only two meters, there are also milling and raw material processing series equipment, which can print metal alloys.

It's not that kind of experimental technology!

The machining accuracy has reached the level of ordinary machine tools, and even CNC machine tools, and the speed is very fast, and it is used to print special material parts, such as titanium alloys.

Some metals are particularly soft, sticky, brittle, and valuable, and the machining cost is very high, difficult, and lossy, and they are only suitable for industrial 3D printing, which is efficient and low-cost.

Before printing, the raw materials need to be milled first, the raw materials are sent to the milling system, decomposed with black technology, stored in the raw material powder tank, and blown into the printer group.

Most of the materials are printed directly, and they can be used normally off the production line, and there are some special alloys, which need to be sintered at high temperature in the later stage, and the technology is very unusual!

The maximum processing size is two meters in diameter.

In order to test the performance of the equipment, Li Wei and his team asked the workers to prepare materials to produce a batch of alloys, and to use an electric steel furnace to make alloy blanks and a milling system to make powder.

The two 10,000 kW furnaces in the casting workshop have been strengthened with limited system, and their performance has been improved, and they can melt most alloys at a temperature of 3,200 degrees +!

Gold, silver, copper, iron, tungsten, nickel, lead, tin, aluminum, titanium... Fifty kinds of common metal and non-metal materials are all within the range of electric boiler smelting alloys, and they can also be vibrated and stirred.

The first batch of trial production of "pore hot dispersion metal" is a kind of secret alloy material, which produces two tons in one furnace, and can be used to process materials that quickly dissipate heat, and has excellent hardness and toughness! It is the best material for producing gun barrels, and the cost is not high.

With sufficient electricity, advanced performance and good heat preservation, the furnace heats up quickly, from 20 to 1490 degrees, it only takes about half an hour, and it can be done in an hour!

"This electric boiler has an advanced structure, and the molten steel can flow directly into the casting area, where it can be cooled quickly or normally according to the processing needs, and the time can be adjusted. ”

"Of course, under normal circumstances, we would have chosen to cool at a low speed to avoid quenching, and we have many different material styles for casting molds. ”

Zheng Bo served as a narrator, explaining to everyone, taking Li Wei, Yu Hao, Zaev, Ling Zhengjun, and Xiao Heizai to visit the furnace workshop and observe the furnace from afar.

After a while, the material is melted, fused, and stirred evenly, and then slowly poured from the side and injected into the vibrating mold next to it. A total of 1.975 tons of cast 16mm steel rods and ordinary steel plates remained.

It is used for the production of gun barrels, protective heat sinks, covers for various engines, and covers for motors, and first of all, a small number of sniper barrels are produced and trial-produced, with a total of 500 pieces.

According to the normal level of machining, if Zheng Bo and they process it by themselves, the 99% pass rate and 95% yield rate are very good, the global elite level!

And the level of the black uncles, 80% pass rate, less than half of the yield rate, the remaining 20% directly scrapped, this is still processed with machine tools, no need for manual...

"It's finally OK, let's try it~"

The black girl Jena can't wait, and the little black boys will also operate all kinds of industrial machinery, eager to try and experiment with new machine tools. Li Wei smiled and agreed:

"No problem, wait for the steel rod to cool down first!"

Zheng Bo: They are more interested in this new alloy, which has high hardness, high toughness, and some memory metal properties, and the material is black and gray.

The main materials are copper, titanium, tungsten, aluminum, steel, manganese and other metals, which can be smelted in a specific proportion, in a specific order and at a specific temperature to achieve the effect.

A millimeter of miss, a thousand miles of difference!

The ratio is a little different, the effect is far from the same, this alloy is said to have considerable superiority in hardness, toughness, elasticity, stress, heat dissipation and heat resistance.

Zheng Bo: They understand that such a metal can be used not only for gun barrels, heat sinks, and shields, but even for aero engines and fighter tails.

In addition to not having a complete R&D system, it is a great success, eager for quick success, and it has wasted 20 years in the development of turbofan six... In addition to these objective reasons, the materials are not good!

It is mainly reflected in the service life, the life of similar turbofan engines in the United States is generally thousands of hours, the Russian-made turbofan engine is thousands of hours, and China's 300...

It's really embarrassing! Hundreds of hours of life, overtime will burn out parts, combustion chamber problems, if you don't do well, you may directly destroy people, chicken ribs of the cheat daddy~

For decades, the blades are not good, the oil leaks are on fire, the combustion chamber temperature is too high, the alloy wheel is not good, and the quality problems have not been solved, and there is not much achievement.

In addition to the material, the process is also important, it is precisely this China's short board, the foundation is too weak; not even the nine-axis linkage machine tool is not, but also the engine of the hair?

Zheng Bo: They have a feeling that Li Wei can solve these long-standing and difficult problems that have plagued China for a long time, and this is a man who creates miracles! Maybe it's very unusual~

After everyone waited for the steel rod to cool down, they used a small cart to send the steel rod to the Seiko workshop, where 5 large [fully automatic CNC industrial machine tools] were like steel monsters.

"Super machine, this is it!"

Fully automatic tool setting, tool changing, tool calibration, processing, double knife co-cutting, three-knife co-cutting, four-knife co-cutting, laser intelligent full-angle cutting, drilling, milling, boring and turning function combination.

Li Wei patted the fuselage with satisfaction, and asked Zheng Bo and the little black boys to step forward and learn how to operate the machine tool, Ling Zhengjun and they were also very curious to look at, feeling that this machine was really big!

The processing size is nearly nine meters, the fully enclosed fuselage is naturally more than 10 meters, and the tool magazine is 3,000.

And the ten engineers knew very well that the performance of this thing was definitely not simple, the size alone broke the record, and it was almost impossible to run four knives at the same time!

It is used to process the barrel of a gun, just a joke, and a knife is used to kill chickens? This is used to process large-scale equipment such as giant oars of ships, spindles of large CNC machine tools, hydropower turbines, and nuclear power units, and there are few in the world.

However, cutting steel rods with this equipment is the most suitable test of precision and flexibility, which is not easy, and for the super machine tool produced by the system, it is easy!

The large fully automatic robotic arm can flexibly and accurately clamp two alloy steel rods and put them on the fixture, which can process two barrels at the same time and process them at one time!

Drilling, grinding, jacking, drawing, laser deburring, the full set of processing only takes two minutes, and it has been over before everyone has reacted, and the library door is opened again.

"Damn! so fast, isn't it?"

"Huh~ It's really good, you see..."

Zheng Bo picked it up with a surprised smile and used a micrometer to measure the inner diameter of the barrel, which was 9.50mm, which showed that the detection accuracy of the micrometer was not enough!
