Chapter 168 Five-axis gantry machining center (asking for monthly ticket)

In order to win on the battlefield, both sides fought hard.

Iraq purchased a large number of artillery shells, and coupled with the continuous arrival of the original purchases, it was accumulating strength to achieve greater results.

Persia urgently placed a second order to purchase more pistols, rifles, machine guns, anti-aircraft machine guns, rockets, mortars, howitzers, cannons, tanks and other weapons and equipment, as well as a large number of bullets and shells. A whopping US$1.5 billion.

Persia is now undergoing emergency mobilization to organize more soldiers and even release a group of arrested officers for this purpose.

Abadan is now surrounded by Iraq, and Persia will never be able to bear the pain of Abadan's fall.

Because Abadan is an oil town!

Abadan is located at the southwestern tip of Persia, on the north shore of Abadan Island in the Shatt al-Arab River, 53 kilometers from the Persian Gulf to the southeast and 15 kilometers from Khorramshahr to the northwest. Since 1909, the Anglo-Persian Oil Company established a pipeline terminal refinery here. , Abadan has developed rapidly. Now the population of Abadan exceeds 300,000. The city's refinery is the largest refinery in the world. The output of the Abadan refinery accounts for 60% of the total Persian oil production!

Once Abadan is lost and its rich oil is lost, Persia will be finished!

This is why Persia is willing to do whatever it takes. Persia has accumulated a lot of wealth due to the rise in oil prices. If it loses its oil, Persia will plummet.

"It seems that Iraq has lost a lot of fighter jets this time. Now it is even willing to import J-7 fighter jets." Liu Tao hung up the phone and looked at the green mountains and green waters outside the office with emotion.

The Iran-Iraq war was a timely rain for China's military industry, which could save countless military-industrial enterprises still in operation.

In the past, when military factories were converted to civilians, a big problem was lack of money.

But now, the money keeps coming.

As long as some of the arsenals maintain production and others open arsenals, a large amount of money can be earned, and the money can be used to complete the conversion of the arsenals to civilians.

I don’t say how much money can be allocated, but the military factories should be allowed to settle workers’ arrears and settle all the arrears so that the military factories can easily go into battle and convert the military to civilians. There should be no problem.

It is quite sad to say that China's most advanced fighter jet is the J-7.

The J-7 fighter is a single-seat, single-engine supersonic jet fighter that was copied from the Soviet MiG-21 in the 1960s. It is the first twice-sonic jet fighter developed by China. It is widely equipped with the Air Force and Naval Aviation. It is mainly used for It can perform homeland air defense and seize frontline air supremacy on the battlefield, and can also perform ground attack missions. It is a typical second-generation fighter jet.

At the same time, the Soviet Union had developed the MiG-25 fighter jet, which was the world's first fighter jet with a speed exceeding Mach 3. In addition, there were Su-17 attack aircraft, Su-15 interceptor aircraft, and the Tupolev Tu-28, which were also developed by the United States. The F-4 Phantom II fighter jet and the F-5 Freedom Fighter fighter jet were produced, and France developed the Mirage F-1 fighter jet and the flagship attack aircraft of the super military.

These fighter jets are all more advanced than the J-7.

Not to mention, the most advanced fighter jets in the world now are American-made fighter jets such as the F14, F15, and F16, as well as Soviet-made fighter jets such as the Su-27 and MiG-29.

In other words, the J-7, China's most advanced fighter jet, is actually two generations behind the advanced fighter jets of the United States and the Soviet Union.

Of course, fighter jets are notoriously expensive. Second-generation aircraft like the J-7 fighter can still be sold for US$3 million each when exported.

This time, China exported J-7 fighter jets at a price of US$3 million each.

In the international market, fighter jets like the F14 have exceeded US$20 million.

Of course, this order is from the Third Machinery Department and has nothing to do with the Fifth Machinery Department.

Production workshop.

Liu Tao placed his hand on a CNC machine tool machining center and looked at the virtual panel:

[Item: Four-axis gantry machining center]

[Manufacturer: Liu Tao]

[Item level: LV9 (1000000000/1000000000) (can be upgraded)]

[Upgrade Points: 500]

[Item status: intact, parsable]

Liu Tao smiled.

This four-axis gantry machining center is a turning and milling compound processing, which is realized on one machine tool through several different processing techniques.

Turning and milling combined processing is the most widely used and most difficult of all composite processing. Such a turning and milling combined machining center is equivalent to a combination of a CNC lathe and a machining center.

"System, upgrade!" Liu Tao said silently in his heart.

Huh~~

A glimmer of light flashes, and the four-axis gantry machining center produces a speed discernible to the naked eye.

When it returned to normal, Liu Tao looked at the virtual panel again. The data on it had changed.

[Item: Five-axis gantry machining center]

[Manufacturer: Liu Tao]

[Item level: LV10 (cannot be upgraded)]

[Upgrade Points: 500]

[Item status: intact, parsable]

Liu Tao looked at the data and raised the corners of his mouth slightly. He finally upgraded to a five-axis gantry machining center.

This five-axis gantry machining center has a maximum X-axis stroke of 21 meters, a Z-axis stroke of 2 meters, and a maximum diameter of the turning and milling table of 4.5 meters. It is specially used for processing large, heavy, and high-precision products.

This big guy weighs a full 70 tons!

This is specially used for processing diesel engine crankshafts.

Tank diesel engines have very high requirements for the crankshaft, almost as much as the processing requirements for the blades.

Place the processed titanium alloy material, select it on the screen, and start.

The processing started immediately. First, the end face was milled with the milling cutter, then the center hole was drilled, the tailstock tip was pressed against the center hole, and the S-type cylindrical cutter was used to rough turn the cylindrical surface.

Processing is carried out step by step according to the control program.

In about thirty minutes, the crankshaft was finished.

Liu Tao picked up the processed crankshaft and showed satisfaction.

Perfect, the processing accuracy is very high.

"With this five-axis gantry machining center, many parts can be solved." Liu Tao secretly said.

With the completion of this five-axis gantry machining center, subsequent parts processing will become much simpler, and the production efficiency of tanks and self-propelled anti-aircraft guns will be improved.

Although Liu Tao was in a good mood, he was not arrogant or complacent.

It's just the beginning now. Tanks and self-propelled anti-aircraft guns can only be produced in small batches, which require a lot of manpower and material resources. If it weren't for him, the entire country might not be able to build a self-propelled anti-aircraft gun or tank.

Even the current Panshan Machinery Factory, which has the technical backbone of Factory 256 and a large number of engineers deployed by the Fifth Machinery Department, still cannot build a qualified self-propelled anti-aircraft gun or tank.

Even a qualified diesel engine cannot be built.

The most advanced tank engine that can be built in the country now is 580 horsepower. If it is higher, there is no way.

As for a diesel engine with thousands of horsepower, it is so unattainable that one cannot even dream about it. Just thinking about it will make people feel despair.

There are definitely no more than 10 people in the country who dare to imagine a 1,500-horsepower tank diesel engine.

And Liu Tao is a person who dares to think and do it, and realizes it.
