In order to organize a mechanical training class, Li Wei arranged to free up the right part of the hangar, which is about 500 square meters; the hangar itself has a navigation crane, various lathes, milling machines, boring machines, drilling machines, pulling machines, and cutting machines.

There are also 100 sets of desks, chairs, projectors, teaching aids and textbooks, stationery tools, like micrometers, electronic vernier calipers, tape measure, and inner diameter micrometer...

There are also pens, rulers, compass, drawings, etc., everyone has a set of them! The students' educational level is like elementary and junior high school, but none of them are from high school.

But it is enough. They know English and have no problem learning machine tool operation. Li Wei recruits students, and these black brothers respond to the call and automatically apply to participate.

One afternoon, after Li Wei, Yu Hao, mayor Zayev, Xiao Heizai, and the militia members were busy, and finally installed the machinery and began to install the wires.

The 200kva cable can drive 200kw of mechanical equipment power, equipped with three-phase and four-wire electricity, spring-speed disconnection switch, circuit breaker, and special socket.

These machine tools are basically CNC-controlled export styles with high accuracy, worth tens of thousands to hundreds of thousands; there are also processing centers of millions, and furnaces are also very expensive!

When operating CNC machine tools, there is no need for cads. The drawings are all set up. Workers only need to process them. The difficulty of drawing is relatively higher, and it is difficult to learn in the short term.

After all, cad has requirements for computer technology.

However, the little black guys can learn it. Their computer foundation is pretty good, so learning cad is a little bit of a joke; the system can help you draw pictures and provide various data.

In the next few days, Li Wei, Xiao Heizai, Yu Hao and others began to study machine tools and learn how to operate them. Li Wei and Yu Hao both have the basics and are familiar with basic operations.

There is no doubt that Yu Hao has also learned to operate various machinery in the army, make simple weapons, and improve the survival efficiency of special operations. It is not easy to be a trump card!

3v7 teaching, the speed is not average. If you learn the basics quickly, you will start to learn operations. Watching Li Wei and Yu Hao teach step by step, processing various workpieces.

shaft, sleeve, gear, winch, barrel...

The little black boys, they are very interested in this, and soon learn to cut nail hammers, and then learn to cut gears, shafts, threaded tubes, and sleeves.

It is actually not difficult to use one through a hundred times, especially after mastering the operation of CNC machine tools, the difficulty is very low. Even Li Wenheizai will also argue and start toward high difficulties.

Complex curved surfaces, combination of multiple processes, high requirements, special materials processing, and all kinds of models must be learned; finally, the passing assessment task is arranged---produced ak47 barrel!

That's right, the AK-47 barrel is processed, a complete set of barrel kit combinations, omitting some details, and a small amount of rough details. If it can be fired, it is considered passing.

The components include gun barrel, ruler, lower guardrail holder, sight assembly, muzzle stopper and fixed lock pin and other components, which is not simple!

The total length of the ak47 barrel is 415mm, of which the rifling part is 369mm in length, the diameter is 7.62mm, and the inner right-hand rifling is 4, and the entanglement distance is 240mm.

The barrel itself is the hardest to produce!

How to process it? Here we just have the conditions, steel pipe cooled satin machine, quenching machine tool, pulling bed... can produce 7.62mm rifle barrels with standard quality diameter.

The little black boys are not stupid. First, they study it carefully and deny the bed carving and rifling. This technique is not good! The cold satin-made gun barrel has burrs, which is not smooth enough at all.

The current mainstream technology is the top cone processing method, using a pull-up bed and sandwiched a top cone; it is like a round bead with four convex points on it.

The top cone is slightly larger than the barrel, and the barrel is wrapped in another steel pipe to ensure that it will not deform. The top cone is pressing forward and rotates at the same time, and the rifle is pressed out, and the burrs are flattened and the air eyes are air-eyed, with higher accuracy.

Production of semi-finished products, then send them to quench to increase the hardness of the barrel, and then the work is done; then assemble other components, sights, rulers, locking pins, locking pins...

Complex, multi-craftsmanship, high requirements, inexperienced, various difficulties are like obstacles, and many obstacles. However, Yena and the others are very serious and have very good talent. They produced ten sets of barrels within two days, and 6 were qualified!

The system elves checked and confirmed that they would definitely not explode after a few shots, and even the quality was pretty good; it was more than those ak-47s in Africa that were imitated, and it was easy to get heat.

Sure enough, Li Wei assembled his homemade barrel on an imported genuine AK-47 and fired ten bullets in a row at the ring target without any problem.

"Dadadadadadada~~" Hit the 85 ring!

The barrel is not severely heated and is a little bit hot, which means there is no problem with the quality and is completely qualified! In the future, the factory can produce barrels and even imitate ak-47.

Theoretically, the factory's equipment and materials are fully qualified to produce rifles, heavy machine guns, mortars, and even heavy howitzers and cannons.

The equipment is complete and technically difficult. After all, there are no professional workers, so it is unrealistic to rely on uncles. A small number of senior technicians must be recruited to manage factory technology!

There are 100 Hei Ge, responsible for front-line operations, and at least ten technicians, preferably senior technicians. However, there is no hurry for now, and the factory is open.

The system began to look for a technician who was skilled, had nowhere to play, had poor conditions, was free of worries, and was honest and honest, and was ready to invite Somalia.

Including a factory manager with management experience!

Back to the topic, the little Heizi learned well, and the training class was about to start. They talked for half a day every day, learned mechanical production technology in the morning, and military training in the afternoon.

Classes are held in a unified manner, and operations are carried out in groups and take turns. Learn slowly from very simple cutting machines, welding machines, sawing machines, grinding machines, stamping and forging machines, one by one.

Cut steel plates, cut steel pipes, weld steel pipes, weld tables, chairs, bench racks, sawing wooden boards, sawing iron plates, sawing workpieces, grinding chamfering and trimming, stamping castings, etc.

In addition to giving lectures, Li Wei either went to the clinic for treatment for the other half of the day, or inspected the construction site, or stayed at home with his girlfriend Ling Yao, who is now his fiancée!

The two of them were inseparable, wishing they could stay together all day long. It was normal for them to have sex. Li Wei insisted on the increase from 3 minutes to 20 minutes!

The little loli also adapted, eating the marrow and knowing the taste, actively cooperating with her boyfriend to make out and make people feel harsh. She can still look cute when she is such an evil thing.

Because the clinic is very busy, Ling Yao also went to the clinic to help with the price and price, and had an affair with Li Wei. She also stole a pink nurse outfit and went home... What to do, everyone must understand, the nurse's uniform ol temptation!

Two days after the passage, Zhao He also called and informed that the arms had arrived at the port and were ready to be sent over. He hoped that Li Wei would arrange a militia to respond and it would be best to transport them away as soon as possible.

The militia, pirate cadet, old squad leader, Yu Hao, Luo Honda and others are all looking forward to equip new weapons and the domineering "Dongfeng Mengshi" off-road vehicle!

Can't wait to go to Port Kismayoo to receive...
