The new machine tool has been assembled and debugged. The factory director Ou Hantao was full of excitement and excitement, and was introducing Yang Tianfeng.

"These two German and Dutch are both precision machine tools, which are the best. They are much more advanced than the original two."

Yes, these three are also the most expensive, the latest ones, of course, are more advanced than the old machines of the original Yang gun factory.

Yang Tianfeng nodded, thinking that the money was worth it. He could buy such a good machine and the real money spent would not hurt him so much.

"With high-carbon steel and tungsten steel, the tooling problems of machine tools can also be solved in the future." Ou Hantao continued, "According to the superior's plan, we will arrange and manufacture a batch of pedal lathes, support small private workshops in the form of sales or leasing, and subcontract more rough processing."

In 1797, British mechanical inventor Modsley created a modern lathe with a screw drive tool holder, and in 1800, he used exchange gears to change the feed speed and the pitch of the thread being processed. In 1817, another British man, Roberts, used a four-stage pulley and back wheel mechanism to change the spindle speed. In order to improve the degree of mechanization and automation, an inventor invented turret lathes, revolving lathes, single-axle automatic lathes, etc. in later eras.

Although pedal lathes are relatively primitive, they cannot be compared with the various high-efficiency automatic lathes and specialized lathes used in modern large factories to drive motors. However, for base areas and even the entire China, they are suitable for small folk workshops that lack electricity.

"The lathes should also be gradually improved, and the variety should be gradually increased so that their functions and efficiency can be improved." Yang Tianfeng smiled bitterly and said: "In terms of productivity, we must not be able to compare with large Japanese companies. To meet the needs of military industry, we can only give full play to our manpower advantages."

"If the whole country can do this like us, there are thousands of small workshops, and the output may not be as good as the Japanese." Ou Hantao was a little dissatisfied, and after saying that, he was a little discouraged. This was just a statement. The government definitely did not have the ability and vision to implement it in this way.

Yang Tianfeng sighed. According to the government's attitude towards private industry, only the Yongcheng base can do it.

As he watched, walked and explained, Yang Tianfeng came to Ou Hantao's office, sat down and chatted for a few words, and then turned to the topic.

"The guns and cannons are basically qualified. In addition to continuing to produce the current types of weapons and ammunition, you still have new tasks to be completed." Yang Tianfeng took out a few drawings and materials and said solemnly: "This is a work that must be absolutely confidential and will still be handed over to the technical team to complete. Parts are manufactured in workshops and assembled, and the most reliable workers must be selected. First create samples, and after passing the inspection, then select personnel to build a production line according to the situation."

The new weapons are first handed over to the technical team to make samples or small amounts of products, for testing, improving, recording data, and planning future production processes and production processes. They do not necessarily manufacture and equip the troops in large quantities immediately, but only reduce the time and pressure of suddenly manufacturing in the future. Simply put, this is a research and development department that turns the drawings into physical objects for later use.

Taking this approach, the weapons produced by the technical team are not only the ones that Yang Tianfeng has brought out now, but also the m1939 37mm anti-aircraft guns widely used by the Soviet Union during World War II, rockets with a longer range that imitated the steel fist launch principle, and 12.7mm heavy machine guns.

The Soviet M1939 anti-aircraft gun was imitated from the Bofos M34 model, but the manufacturing process of parts was much rougher, and it was replaced with a simple gun chassis and sights. Those who have watched Korean War movies should be familiar with this weapon. The actual combat shows that the rough workmanship of the m1939 anti-aircraft gun was extremely suitable for the national conditions of the Soviet Union at that time. Its "cut corners" greatly reduced the manufacturing cost, which was very conducive to mass rapid production during wartime.

Similarly, for the current arsenal, "short-made" weapons are more suitable for their technical level and production capacity. Yang Tianfeng also sent the drawings to the rear, hoping to successfully imitate them and enhance the air defense capabilities of the rear.

As a light anti-aircraft gun, the m1939's light and flexible characteristics are valued by Yang Tianfeng. It can not only prevent air defense, but also combine special shells such as armor-piercing shells, which can pose a threat to Japanese tanks and armored vehicles at a longer distance.

The crude rocket can make up for the defects of the flying thunder cannon in range. It has great power, high safety, and accurate heads. Of course, it cannot strike accurately, but it can be compensated by the power of dozens of kilograms of explosives.

Seeing that Yang Tianfeng was speaking seriously, Ou Hantao knew that the matter was serious, he hurriedly took the drawings with Deputy Factory Director Li Jianye and read them roughly.

The most outstanding machine gun mg42 in World War II, also called "Hitler chainsaw" by Allied soldiers, represents an important breakthrough in gun production technology. The arrogant and domineering American soldiers were depressed by it, had no intention of fighting, and were depressed, and regarded it as "the nightmare of infantry." Light weapons critics used it three most advanced adjective phrases: "The shortest time, the lowest cost, but the best weapon."

When mg42 was just born and equipped with troops, in the eyes of the Western intelligence personnel lurking in Europe, it was actually a shoddy weapon, a piece of iron piece and an iron pipe.

At that time, the snowflake-like report flew to Washington and London, and the content was the same: Germany was no longer possible. They were extremely lacking in raw materials, and even the machine guns at their core tactical use such simple and crude manufacturing technology.

However, when American and British gun manufacturing experts learned about this situation, they were shocked. They knew clearly that the German army, which adopted stamping technology, had already led them in machine guns. This was also well proved in later actual combat.

In fact, mg42 produced by metal stamping process not only saves materials and labor hours, but also is more compact. It uses very few materials and can be manufactured through simple assembly lines.

During World War II, about one million mg42 were produced (some say 700,000), which was very amazing. You should know that during World War II, the production of German submachine guns was only 1.2 million, and such a high production volume was shocking. Weapons with such excellent performance and so easy to manufacture, the term perfection is not an exaggeration to use on it.

"Did you see it? Metal stamping process, this will be an inevitable trend in weapon production." Yang Tianfeng briefly introduced the key points, "In order to cooperate with this weapon and equipment force, you must also work with the iron smelting plant to speed up the progress of imitation rolling mills and increase ammunition production. When this machine gun is fired, the consumption of bullets is absolutely shocking."

The shell rolling mills in the arsenal are also from the Yang's gun factory. Not to mention the production and manufacturing capabilities, the key is the shortage and lack of copper materials, which also restricts the production volume of ammunition in the rear.

China lacks copper and has to rely on large amounts of imports. This is a hurdle that cannot be overcome, but it is not a difficulty that Yang Tianfeng cannot solve.

Of course, Ou Hantao and Li Jianye knew this difficulty, but they also knew that the ironworks were developing copper clad steel. When they were linked together, they understood Yang Tianfeng's true intention.

If copper clad steel can make bullets and shell shells, in theory, it will save at least 80% of copper material. Now the production of ammunition will not only be reinstalled and re-rolled, but remelted copper shells and re-engineered copper shells and re-engineered copper steel shells, which will increase the utilization rate of the materials by five or six times in a row.

The production and manufacturing of a weapon and putting it into practice is a very complex process. Taking the mg42 general machine gun as an example, Yang Tianfeng was able to take out the drawings long ago, but when the guns, cannons and steel did not meet the standards, the ammunition materials and production capacity did not make breakthroughs, and other conditions were not met, what's the use of production and manufacturing?

Judging from the current situation, the anti-Japanese armed forces, including the National Army, used rifles and had insufficient ammunition, so how could they talk about automatic firearms that consumed amazing bullets? Without bullets, what advanced tricks are not just a fire stick?

Besides, do the Japanese devils have no ability to develop automatic weapons? Of course, it is not only because of the lack of resources, but also because of different combat concepts, so they are equipped with rifles.

The mg42 general-purpose machine gun at least uses Mauser ammunition, which is the same 7.92x57mm specification as the official rifle. In other words, the machine gun can be used after being made, but the ammunition is tight.

Imitation rolling mills are also accumulating experience and preparing for future self-made gun rolling mills of different specifications. Yang Tianfeng thought carefully and planned clearly, and walked forward step by step.

As for the method of supplying bullets, Yang Tianfeng decided to temporarily adopt the 75-round drum style. It imitates the drum made by the state-owned 356 factory in Kunming, which is convenient for opening the cover and quickly loading. Skilled people can fill the bullets in a few seconds. As for the advantages and disadvantages of the links and drums, Yang Tianfeng certainly knows that the use of drums temporarily is also considered to save ammunition and adapt to the real war environment.

According to the operation regulations of the Slaughter of the Japanese, at most, after a drum is fired, the machine gun must be transferred to the position to prevent the Japanese artillery fire from being destroyed. In this way, using the drum is much more mobile than the link.

"The air-cooled type is lightweight and small in size, but it is more complicated than the water-cooled type." Ou Hantao looked at the drawings and said his thoughts.

"Oh, look at this, it's because of the rapid replacement of the barrel to make the shooting last." Li Jianye pointed out: "When heavy machine guns are used, there are special heavy barrels."

Yang Tianfeng did not interrupt and waited until the two of them saw the drawings almost complete, and then he spoke: "According to the current technical level of the arsenal, there should be no problem in manufacturing a general machine gun. The key is to explore and research the simplest manufacturing method, that is, to fully master the stamping technology, rather than relying on machine tools such as milling and cutting."

Ou Hantao thought for a while and turned his attention to Li Jianye. The two nodded at the same time.

"Although there are difficulties, we strive to overcome them." Ou Hantao represented the guarantee, "machine tool processing is time-consuming and labor-intensive. If stamping technology can be overcome, many future weapons production can be used, which is faster and more convenient."

"With high-carbon steel and tungsten steel, the problem of molds is basically fine. I think other difficulties can be solved," Li Jianye nodded in agreement, "General Yang will also do his best to help, right?"

Yang Tianfeng nodded and said, "The hydraulic stamping machine is being manufactured, with the assistance of several experts from the rear. I think this will be completed soon. By the way, you must also send personnel to observe and learn, and you can copy it together with the technicians of the iron plant in the future. To expand the production scale, only one is far from enough."

"I'll go in person." Ou Hantao studied mechanical engineering and his major was more appropriate, so he volunteered without hesitation.

"Then I will stay in the factory, supervising production, and working with technicians to formulate a general machine gun production process and start trial production." Li Jianye immediately took over the work of the arsenal.

Ou Hantao glanced at Lao Teng's crotch, and the two showed a knowing and trusting smile.
Chapter completed!
