For mechanical measurements, the most commonly used are micrometers and vernier calipers, which basically meet the needs, and if higher accuracy is required, electric induction probes can be used. Pen, fun, pavilion www. biquge。 info

The micrometer accuracy is 0.01mm, and the electronic inductance probe has an accuracy of 0.0001mm, which is more than enough for the machinery factory, and there are various styles!

Zheng Bo randomly chose an imported probe and skillfully measured the size of the barrel, which is very easy to use, and the accuracy is very accurate, and it is generally not easy to make mistakes.

Stick it in and have a degree: 9.5000mm.

"Damn! This... This is impossible~"The error is less than one ten-thousandth of a millimeter? What are you kidding, it can actually reach this level, more advanced than Lao Mei!

Zheng Bo was stunned, looking at the electronic display in a daze, a little incredulous, and several other engineers were also stunned, they couldn't measure it...

1/100 micron level accuracy! Nine-axis linkage CNC machine tools are also difficult to achieve, almost don't even think about it, faintly reach the normal limit, should not be so accurate.

"Hey~ what's the situation? What's wrong with you?"

Mayor Zaev asked curiously, and the engineers shook their heads in confusion and replied: "I can't measure it, I can't measure it, I can't measure it! This machine is too powerful!"

"What can't be measured? Why?"

"Because the measurement limit is exceeded!"

After some explanation, everyone finally understood how awesome the measurement results were!9.5000mm, indicating that the accuracy is still in the back digits, and the instrument did not measure it at all.

It's amazing, it's incredible, Li Wei explained to them: "Actually, it's normal, this machine has a laser deburring function, and the accuracy comes from here." ”

Everyone suddenly realized, it turns out that it is difficult for machinery to achieve this kind of accuracy, but the laser can be accurate to one hundredth of a millimeter, or even higher!

However, the scientific and technological content of lasers, especially high-power laser cutting, is not generally high, and the current laser technology is not mature, and deburring is not realistic.

It can be seen from this that this industrial machine is really a very unnatural black technology, and it is used to process the barrel of a gun that is purely a waste of valuable performance! It is necessary to develop a new project, and Zheng Bo and they all suggested that they should engage in aviation precision manufacturing.

Aviation, aerospace, missiles, nuclear power, marine engineering, aircraft carrier propellers, machine tool spindles, tool magazines... These are all alternative developments, and the margins are exaggerated.

Li Wei expressed his support with satisfaction, and asked them to continue to study the six-axis machine tool and engage in it after a while! The whole set of things has the highest value, and the profit of making parts and components is low.

Of course, except for the difficult ones, such as the engine powder alloy wheel, as long as it can be produced well and close to the performance level of Lao Mei, it is definitely not cheap.

However, the most profitable is the finished product, a new machine tool designed by elves, with an accuracy of 0.00005mm, higher than one ten-thousandth of a millimeter, which is terrifying!

This kind of accuracy surpasses the smuggled machine tools of China's most cutting-edge military aviation enterprises, and is not worse than the nine-axis linkage machine tools produced in Germany, and a little worse than that of island countries.

The world's highest precision machine tool, currently belongs to the island country CNC machine tool, 30nm level accuracy, that is, slightly higher than the machine tool provided by the system, 20 nanometers.

But the processing size is much larger than that of the island country!

Moreover, the stability is extremely high, two cutter heads, intelligent precision monitoring and repair, faster turning speed, and the productivity is at least equivalent to 3-5 30nm machine tools in island countries.

The main problem of China's machine tools is that there are always all kinds of small problems, strange, sometimes the accuracy is suddenly reduced, and there is a failure for no reason.

50nm stable CNC machine tools are very attractive to China, and the market demand is huge!

The accuracy of this [automatic CNC industrial machine] is much higher than 30nm, and the system must be a high-quality product, with the highest precision reaching 1 nanometer [0.000001mm]

1 mm = 1,000,000 nm,

1 nm = 0.000001 mm,

1 micron = 1000 nanometers,

1 nanometer = 0.001 micron

Speed, multi-function, laser, super tool magazine, intelligent monitoring accuracy, large-size processing, not to mention these aspects, it is completely black technology~

Ling Zhengjun looked at Li Wei, this son-in-law is becoming more and more sharp, and he feels mysterious, I really don't know how far he can reach in the future, which makes people look forward to it!

Zheng Bo, Yu Hao, and Little Black Boy have deepened their admiration for their bosses, and even admired them a little; the members of the engineer team who are engaged in technology have admired people like Li Wei who have mastered technology, such as worshipping idols.

BCP carbon fiber, micro nuclear power, super machine tools, all kinds of black technology, they regard it as treasures, for technical researchers, technology is the meaning of life.

After receiving the task, these overtime maniacs went back to work again. Organize production during the day, stay up late at night to study the drawing process and learn the technology.

Li Wei was also impressed by the hard work attitude of the engineer team who forgot to sleep and eat and got up early and felt dark, and decided to increase the monthly salary to $5,000!

New machine tools designed by the system, power motor, super tool magazine, spindle, program, shell, base, circuit control system, robotic arm... They all made themselves.

Of course, the core technology cannot be leaked!

Other components, parts, kits, and accessories can be split and contracted, and Yang Hongtao's Nangong Electromechanical, Yuanlu Technology Group, and Hudong Group can help with production.

According to the promotion intention, Iran is willing to purchase 200 units of this new machine tool [price of 8 million US dollars], and China is willing to purchase 400 units, with a 20% discount.

They are willing to pay a high price, the reason is very simple, both countries are subject to European and American sanctions, strict restrictions on machinery, more than five-axis linkage CNC machine tools, not allowed to sell.

Of course, Li Wei is not afraid of European and American countries, he and Iran are strategic partnerships, even if the other party purchases nuclear power parts, he will sell them, and he will not make money if he is rich!

Not only do they want to make money, but they also want to help bring the industrial level of China and Iran to a new level, and let the allies become a little more reliable, so as not to underprice too much.

In addition to the main business of the new [six-axis linkage CNC machining center], there are also customized equipment to promote guns, powder alloy wheels, high-temperature tungsten alloy parts, impellers, ship paddles produced in the two countries...

Iran was very face-saving and quickly agreed to purchase aero-engine wheels, compressors, heat sinks, etc., large hydropower units, cargo ship spindles, and tungsten drill bits.

Mixed with some special alloy parts, it is required to be able to withstand huge pressure, high temperature, corrosion, radiation and other harsh working environments, and must ensure absolute safety.

There are all kinds of pipelines, steam turbines, shells, complex structure connection sections, safety valves, transmission shafts, etc., the use of which is tacitly known, and the processing cost is quite good!

Of course, Li Wei is also in charge of the materials, Iran's industrial level is too poor to be studied at all, and the Russian technology is rough and solid, and the material technology is not good.

European and American technology is clearly the most advanced!
