In the equipment department, the craftsmen surrounded Xiao Ming in the middle.

All the production orders came from Xiao Ming. This craftsman was responsible for forging the main spring, and he was in charge of forging by 500 craftsmen. That craftsman was in charge of striking iron, and he was in charge of production by 400 craftsmen.

There are 500 craftsmen in charge of assembly and 700 craftsmen in charge of butt production.

"Now keep in mind the size of your own spare parts, and then forge them according to the unified size standard. All parts with large errors will be discarded and cannot be handed over to the assembly craftsman. If the size deviation in the production of spare parts exceeds 5%, you can only punish them according to the rules of the workshop."

There is a hint of warning in Xiao Ming's voice. He has always been very strict with production. In later generations, there are too many fake and shoddy goods, which is a cancer of industry.

So from the industrial point of view, he strictly shaped a rigorous spirit in the process.

For production, there is no carelessness, only continuous improvement.

When the machine and butt are put into production, the rest is the barrel.

Zhang Liu has not been idle for a month. He has been preparing knives. Compared with guns, this technology is also very difficult, so Xiao Ming has to participate in this work in person.

This month, the equipment department has stored some tungsten powder. Because of the original carbon reduction method, the reduced tungsten powder always contains too many impurities. Finally, the fine tungsten powder has to be screened, which is very rare.

In modern times, Xiao Ming's method is a huge waste, but it's worth it to him, because he doesn't need too many knives now. He just needs to meet the needs of Qingzhou. At most, there are about 500 of each kind of knives.

After all, the number of lathes in today's water conservancy lathe workshop is no more than this number, which is also a waste. When the number of lathes is increased, it can be prepared accordingly.

When song Changping and others leave, Xiao Ming goes to the backyard of the equipment department, where the craftsmen are polishing the knives.

After more than ten failures, Xiao Ming gradually realized that the process of using tungsten powder to compress and calcine tungsten steel could not be realized in Qingzhou for the time being.

The most important thing is that the exploitation of tungsten can't keep up. Secondly, the quantity of tungsten powder extracted is also very rare. Now the reserves of tungsten powder are only about two kilograms.

But in this way, he couldn't produce many tungsten steel cutting tools at all, so he decided to go back and ask for a second time.

A few days ago, when Zhang was asked to stay in smelting steel, he added a small amount of tungsten powder and chromium powder to produce a harder alloy than the current Qingzhou steel.

This kind of cemented carbide, also known as ferrotungsten in later generations, is also one of the alternative materials for cutting tools.

This kind of cemented carbide takes tungsten as additive to steel, and the amount is generally small. In steel, it is slightly dissolved in molten iron. Because of its low solubility, it can only be added in a small amount.

In this way, the production of cutting tools is on the way to normal.

Zhang Liu and his craftsmen also successfully produced the "tungsten steel" of this era.

"Your Highness, the cutters of boring machine and milling machine are very smooth, but the drill bit is not easy to grind. However, after so long time, two pieces have been polished. Please have a look, your highness."

Zhang Liu came here with two drilling tools.

The successful refining of tungsten steel is followed by the production of cutting tools, which is consistent.

Taking the knife, Xiao Ming glances at the hand grinder, which he thinks is the most suitable grinder in Dayu.

This kind of grinder is purely manual. Generally speaking, it is composed of two parallel wooden sticks with a grinding wheel in the middle. An iron bar is used to pass through the middle of the grinding wheel and fix it.

The iron stick sticks out of the wooden stick, outside is something like a bicycle pedal.

This kind of mountain machine can be either hand cranked or pedaled by one person by bicycle.

In this way, the grinding wheel will turn.

Touching the twist drill just ground out, Xiao Ming said, "how long did it take to grind out this drill?"

"All day." Zhang Liu sighed: "boring tool and milling tool is easy, but this is always easy to break."

Xiao Ming nodded, which is very normal, because the tool is hard and brittle, so it is easy to break.

He said: "add some people. At the end of this month, at least 100 drill bits will be provided to the water conservancy lathe workshop. The flint gun is short of barrel."

Zhang Liu nodded, "yes, your highness, I'm going to allocate some skilled craftsmen to grind knives."

After a month of working day and night, Xiao Ming finally saw the hope of suifa gun.

However, there was not much time left for him. The barbarians in the north were covetous, and the Japanese separated from the East were also evil.

He had to fight against the clock to consolidate his fiefdom.

When he handed the drill to Zhang Liu, Xiao Ming said, "if you grind out a few, you can send them."

Then he went to find Chen Wenlong and asked him to go to the iron and steel workshop to focus on the production of steel bars.

And he told him all the dimensions of the steel.Now the flint guns are produced one by one. He has been waiting for the tungsten mine for such a long time, but he doesn't want to wait any longer.

After leaving the equipment department, Xiao Ming was in a good mood. It seemed that the air became fresh at this moment.

Dayu's science and technology has lagged far behind this era. From the beginning of artillery, he began to catch up step by step.

Now the second hot weapon appeared, and he was a little more stable, because he always worried that one day he would be suddenly pointed at his head with a flint gun.

Going to the palace, Xiao Ming, who is in a good mood, is going to discuss with lvluo to customize a military uniform for himself. When he arrives at the door, he sees Wang Xuan.

At this time, Wang Xuan's face was pale, and his arms were bandaged, very fragile.

"What's the matter?" Xiao Ming frowned in a moment.

Wang Xuan looked a little tired, he said: "Your Highness, please speak in the main hall." While talking, Wang Xuan also looked around.

Xiao Ming nodded. Wang Xuan was always very careful. I'm afraid he was worried about information leakage.

When they arrived at the main hall, Xiao Ming asked, "what's the matter?"

"We've been betrayed and exposed our identity on the grassland. If we hadn't met captain leiming, the lower officer might not have come back." Wang Xuan said.

Then he recalled: "since the last time we found that the barbarians were forging guns, our secret guards sent a number of people disguised as merchants to enter Shengdu. This time, secret guards reported that they had found the test firing site of the barbarian guns, so the next officer decided to go to find out in person. We did see the barbarian guns in the suburbs of Shengdu, but the appearance of the barbarian guns was similar to ours Their guns are yellow and green, and their barrels are thick and long, four or five meters long. " Wang Xuan said.

Xiao Ming immediately narrowed his eyes when he heard the speech. The gun described by Wang Xuan is a bit like the wuerban gun in history.
