The supervisor took over the gun base, took out the calipers, small scales and other tools from the bag and measured them carefully, and then wrote down the date and process step number on the booklet next to Li Jinggong's desk, and then pressed the handprint, which was regarded as a verification pass.

Only then did Li Jing put the gun base on the drill floor again, fixed it with a wooden clip, and then gently pressed down the upper part of the drill platform, and turned the zigzag handle on the side with his other hand with a not very skillful movement.

The drill bit is driven by a series of belts and several gears to rotate rapidly, and then falls steadily on the iron, splashing iron filings everywhere.

Although Li Jing has many opinions on the current process standardization, this drill floor makes him extremely impressed. Compared to the driller he used to use that rotated with a bowstring, it was not only extremely fast but also very stable, and the drilling hole was round and not skewed.

You know, although the twist drill he is using now seems simple, it was invented at the beginning of the twentieth century, and the drilling efficiency is extremely high after functional calculation.

Li Jing remembered that in the technical school today, Master Xiang said that in the future, pure manual processing should be reduced as much as possible, and sooner or later, the entire Ordnance Bureau would be replaced with convenient machinery similar to this kind of drill floor.

It is said that those craftsmen from Jiangxi also brought a thing called "boring machine", which is even more amazing, it used to take seven or eight days to bore a gun, and it took less than half a day to use that thing. Moreover, the boring hole is smooth, and there is almost no boring.

If so, it's not bad to standardize the process. He secretly said in his heart that as long as he followed the rules of the "Process Manual" and got used to those meticulous new tools, he would be able to work a lot easier in the future.

……

In the evening, the craftsmen of the Ordnance Bureau had finished their work. Zhu Linmiao took Song Yingxing, Xiang Feng and others to start patrolling in various workshops.

Recently, as soon as he left the Wenhua Palace, he rushed to the Ordnance Bureau to promote the standardization of the process.

Although the workshop was empty, the craftsmen had put all the workstations in order by the end of the day, and it still looked like a modern workshop.

Zhu Linmiao walked to the finished product stacking area, picked out two pairs of guns, and took out the tools to measure carefully, although there are still some deviations between the two, but in general, they can be regarded as universal parts.

He turned around and took a pair of flintlock guns that were not equipped with a gun machine from Xu Erlu on the side, and installed the gun machine in his hand. The machine and the bed are very consistent, and the maximum gap is the width of two hairs, so basically the machine can be loaded and fired after it is fixed.

He looked at the craftsman's name "Li Jing" engraved on the machine again, and nodded with satisfaction. What seemed trivial in later generations was no small miracle in the seventeenth century.

You must know that the firecrackers of this era are all handmade, and the craftsmen work independently, even if the same model of firecrackers, the parts cannot be used together. If one part of a gun is damaged, the whole gun can only be repaired by the gunsmith.

The machine in his hand and the machine are made by two different workshops, and how they can fit together shows that the standardization of the process has begun to show results.

After the process standardization is mature, the assembly line production mode can be further implemented.

This thing is one of the industrial killers, which can increase the efficiency of mass production by several times or even ten times!

Moreover, there is another advantage of assembly line production that cannot be ignored, such as making guns, and there will be no guns in the future, but instead of boring pipe makers, machine bracket craftsmen, and gun bed makers. In this way, the difficulty of training craftsmen is reduced several times.

With a high-efficiency large-scale industry, coupled with a large number of available craftsmen, the realization of the industrialization of the Ming Dynasty is no longer far away.

After that, Zhu Linmiao and others walked into a workshop for making pipes. At present, there are only two boring machines, which were brought by Lu Ning from the Suji Iron Yard, and there are only three rifling equipment, so there are only six or seven guns in the finished product area.

Zhu Linmiao measured all the guns one by one, but only the diameter of four of them met the error requirement of 0.1 mm, and the error of the rest was close to 0.15 mm.

He turned to Xiang Feng and said: "The verification should be stricter, even if the output is low, you can't let the non-standard finished products pass." ”

Xiang Feng wiped his sweat and hurriedly lowered his eyes and shook his hands, "Remember." ”

Zhu Linmiao said to Song Yingxing again: "It seems that we still have to set up a 'collection department', and set up a special department to be responsible for verification." Only when the last gatekeeper is meticulous can the craftsmen strictly implement the standardized process. ”

"Yes, the student will do it tomorrow."

In fact, the pass rate of four-sevenths has made Zhu Linmiao more satisfied, after all, it has not been long since the process standardization began to be implemented.

Even if this yield rate remains unchanged in the future, the cost of making 30,000 rifled guns can be reluctantly accepted by pouring the efforts of craftsmen in Jiangxi and Fujing. This is more than ten times better than the situation where only more than 200 of the 4,000 guns can be used as rifled guns.

And it is foreseeable that as the craftsmen become more and more skilled, the yield will definitely continue to increase, and sooner or later, the cost of rifled guns will drop to a level close to that of flintlock guns.

He then instructed Xiang Feng, "From now on, the Ordnance Bureau will make every effort to produce the Type 2 Hunter Gun, and the required expenses will be reported to me directly by Mr. Song." ”

"The subordinate obeys."

Zhu Linmiao turned to Xu Erlu and said: "Far from being the best at casting cannons, I will leave the matter of process standardization to you." Oh, by the way, the copper will be used in the future, don't worry. ”

"Yes."

When these tens of thousands of rifled guns are equipped with the Dragon Guard Army and the Broken Battalion, plus a large number of field artillery with uniform specifications, the combat effectiveness of the Ming Army will achieve absolute crushing of the Jianyu.

Zhu Linwei sighed in his heart, at that time, even if Dolgon fought hundreds of thousands of troops, it would never be possible to stop him from leading the army to the Northern Expedition and recovering the two capitals!

"When the process standardization of the Fujing Ordnance Bureau comes to an end, Mr. Song and Weiyuan will go to Jiangxi again to implement standardization in the Ganzhou Ordnance Bureau and Suji Iron Field.

"In the end, all the workshops under the Ministry of Industry must complete the standardization of the process, and the actions of the imperial court will affect the folk craftsmen. At that time, in Fujing alone, the output of weapons and civilian equipment will far exceed that of Jianyu. ”

A few people present didn't expect what they did to have such a huge effect, and they all said solemnly: "The students (lower officials) will do their best!" ”

As he was talking, he saw Shi Lin coming quickly, and said to Zhu Linmiao: "My lord, Zhu Gebu asks to see you." ”

"Zhu Jizuo?" Zhu Linmiao frowned slightly, "What's the urgency for him to chase here?" Let him go to the main hall of the Ordnance Bureau. ”

"Yes."

After a while, Zhu Linmiao came to the main hall, Zhu Jizuo hurriedly stepped forward to salute, and before Zhu Linmiao asked, he hurriedly said: "Your Highness, it should be noon today." The Helan people bombarded the sea ships that carried grain to southern Fujian to the west of the Nan'ao Mountain, destroying one and wounding two. The head of the ceremonial department who accompanied the ship was also injured by artillery fire. ”

Nanao Mountain is an island south of Zhao'an, less than 100 miles away from Zhao'an, and the Helan people swaggered here to attack the merchant ships of the Ming Dynasty.
