In the Daye Military Arts Supervisor, the craftsmen are making artillery workshop. They install the model cast artillery tires on the lathe, causing the heavy gun body to rotate around the axis, and a sharp turning knife leans against the gun body, shaving the surface of the gun body very smoothly.

On the other hand, a cannon that had been processed from the outside of the gun body was installed on the boring machine by a craftsman and also rotated continuously around the axis. At the same time, a thick long pole penetrated deep into the barrel, and the boring tool at the end of the long pole cuts the inner wall of the barrel and cuts it into a smooth inner wall.

Boring machines and lathes are now the most important processing tools and are widely used in various manufacturing and processing industries. Lathes are used to process the surface of workpieces, while boring machines are used to process the interior of workpieces.

The boring machine in Daye Artillery Factory is the best boring machine in the world. It can cut the inner wall of the gun barrel made of bronze to an extremely smooth.

Only in this way can the artillery be durable, otherwise the various defects in the inner wall will easily be expanded by the burning gunpowder when firing the shells, and finally explode.

Lin Youdi, who had been inspecting this, looked at these giants processing artillery and remembered many past events.

He watched the lathe and boring machine grow up with his own eyes. Twenty years ago, in the Anzhou Prefecture Zhenganlu, he was ordered by the Langzhu and began the exploration of lathe with his ignorant subordinates.

Time passes, the simple lathes of the past and the boring machines developed on the basis of lathes have now grown into complex precision machinery.

The trial sailing of the steamship was "successful". Lin Youdi gave the technical research team a vacation, but he came to Daye by himself to see how the production progress of the artillery factory was. This was one of the things the emperor was most concerned about, so he would remind the supervisors from time to time.

The official army is the minion of the emperor, and weapons are the minions of the official army. How to create more powerful weapons is the responsibility of all employees of the weapons factory. They must not be satisfied with their existing achievements and do not intend to make progress.

Especially for the improvement of lathes and boring machines, we must persist. These two tools have a "dual effect" on the rapid development of manufacturing and processing industries.

Just as people rely on teeth to eat, lathes and boring machines "chew" workpieces, they rely on tools. Whether it is turning or boring tools, it determines how great the "magical power" of lathes and boring machines can be. But now, the magical power of boring machines is still not satisfactory.

For artillery production, the processing of the barrel is the most critical. The smooth and flawless barrel determines the durability of the gun. Once improperly handled during production, it will leave hidden dangers and will easily explode in the future. Therefore, the best method for manufacturing the barrel should be directly bored.

When using the model method to make artillery, the inner chamber of the artillery is prone to trachoma and bubbles, which is a very serious hidden danger. However, if a bronze column with a symmetrical texture is directly forged, and then a boring machine is used to bore the barrel of the bronze column, such a barrel will definitely have no flaws and be strong and durable.

The idea is good, provided that the tool of the boring machine and the long rod that fixes the tool is tough enough, but with the current metallurgical process, such tools and long rods cannot be made.

The cannon tire can only be cast with a model first. The cannon tire already has a cannon bore, and then the cannon bore is a second process using a boring machine.

As of today, long poles that are strong enough to fix the boring tool and long poles cannot be made, but Lin Youdi did not blame the technicians because he knew that this involved metallurgical technology, and it was really difficult to improve it.

The emperor also knew it, so he did not give a dead order. The lathes and boring machines of the artillery workshop actually met the use requirements.

Daye Artillery Factory produces qualified artillery every month, and then after careful inspection, the artillery is transported to the destination according to the Ministry of War’s order.

There are only five factories in the world that can make artillery, and Daye Artillery Factory is one of them. The guard is very tight and idle people are not allowed to approach. If you want to enter the workshop, you do not have the double permission of the Ministry of War or Seiko Academy, even important officials in the court are not allowed to enter.

Lin Youdi has a special identity. As an old man from the Emperor's Secret Residence, he was in charge of various precision craft industries and brought out many technical backbones. These technical backbones are now the main managers of various workshops. Daye Artillery Factory was also established under his leadership, so he has a special pass and can enter and exit the artillery factory at any time.

Looking at the complex and huge lathes and boring machines in front of him, he couldn't help but think of the simple lathes he and his friends assembled in Anzhou Prefecture twenty years ago.

In the blink of an eye, twenty years have passed, and the simple lathe has now "grown up".

The boring machine that appeared on this basis not only bore the barrel, but also has many uses. The cylinder of the steam engine is one of the most important uses of the boring machine. With this processing tool, the cylinder production of the steam engine has escaped the embarrassing situation of pure handmade production and has achieved standardized production.

With a lathe, you can "carry" the piston of a specified size, and the accuracy is very high; with a boring machine, you can "bore" the cylinder of a specified size, and the accuracy is also good.

The gap between the cylinder and piston produced in this way has become very small. With the appropriate sealing gasket, the piston has much better sealing properties than the purely hand-made cylinder.

But even so, the speed of the steamship still cannot be increased.

Lin Youdi thought about it, and then thought of the steamship. He thought of the tide of cheers on the dock that day, and the steamship that had been knocked down by the medicine, and he couldn't help feeling a little sad.

At this moment, he came to the other end of the boring machine, where the steam engine that powered the boring machine was located. The power steam engine transformed by the steam pump was driven not by the pumping pump, but by the tool of the boring machine.

The boring machine should not cut the inner wall of the cannon bore, otherwise the tool will turn red and "soft" due to excessive heat. Therefore, the boring machine in the cannon factory has low requirements for speed, and it is also very suitable for use if it is turned five to six times per minute.

After all, the rotation speed is enlarged by the gear set, and it is enough to drive the boring tool to rotate.

Lin Youting has only heard the introduction and knows that the boiler that provides steam for the steam engine is the latest boiler. With the same coal consumption, the steam volume has increased significantly.

It is precisely because of the continuous power that the boring machine in the factory is full of power. Now, he found that one of the steam engines is in a wrong state: it actually uses a dual-cylinder.

Just as the steam pump relies on the cylinder piston to drive the lever and the other end of the lever drives the pumping drum, the steam engine that drives the rotating of the boring machine tool in the factory also drives the lever through the cylinder piston, and then the other end of the lever drives the flywheel, turning the reciprocating movement into a rotating movement, so that the boring tool continues to rotate.

But a normal steam engine uses a cylinder to drive the lever, just like a person playing on a seesaw, and the other end of the seesaw is a heavy rice bag.

However, the steam engine in front of me has added a cylinder to the other end of the lever, and the piston connecting rod of the cylinder is connected to the half-side lever arm and is located in the middle position.

Therefore, this steam engine is moved by two cylinders pulling the lever, and it looks like there are people at both ends of the seesaw.

The accompanying staff saw Lin Youdi very interested, so they explained.

Since the factory installed a new boiler, the steam volume has increased greatly and large-capacity cylinders are needed, so the original cylinder with a smaller capacity is useless and it still takes up space. It should be returned to the furnace and use waste.

But several technicians thought this was too wasteful, so they figured out another way to utilize waste, which is to push the towing lever movement of the dual cylinder. After calculation, they believed that this method could also be perfectly matched with the new boiler.

After actually using it, everyone was surprised to find that when two cylinders with small capacity were used together, with the same steam volume, compared with a large capacity cylinder, the output power of the "dual effect" of the dual cylinder is indeed not much lower.

Everyone is happy that the waste is successfully utilized and the cost is saved.

Hearing this, Lin Youdi asked: "What about the money saved? How to deal with it?"

An official replied: "Of course, 80% of them are taken out and distributed to these technicians as rewards."

"Yes, do it well, otherwise why would technicians rack their brains to save money for the factory?" Lin Youdi nodded when he heard this. To increase the enthusiasm of technicians to improve the process and machinery and equipment, there must be rewards.

Just imagine, if a factory employee came up with a solution to technically transform the production process, saving the employer a hundred currencies, and as a result, he would only have the word "good" and add an extra egg for dinner, then no one would use his brain to improve the production process in the future.

Lin Youdi felt that as the Lord of the Lang... the emperor said, technological innovation must bring tangible benefits to people, so that more people will rack their brains to find solutions instead of waiting foolishly for others to discover new technologies.

The technological development of an industry must first rely on the desire of factory owners for technological innovation, that is, higher production efficiency, lower production costs, and higher profits, so that the factory owners can use and study new technologies.

The factory owners’ demand for technology depends on the continuous exploration of technical personnel, and need to use material rewards and economic interests to stimulate technical personnel to conduct technical research.

If you just talk about "dedication" all day long without material rewards, who will be attentive? The factory owners and technicians will not.

Lin Youdi walked outside the factory, but heard the official continue, "Not only that, the factory also invested money to apply for a patent for them. Of course, this patent can be used for free in the factory."

"By the way, the patent has been approved yesterday."

Lin Youdi felt a little strange when he heard this: "Patent? What's so strange about the twin cylinders? Didn't it have been available a few years ago? I can't tell who used it first and where did the patent come from?"

"Besides, when using twin cylinders, it was difficult to make qualified large cylinders by hand, so it was just a temporary solution. Now with a boring machine, it is very convenient to make large cylinders. Can the guild also approve it?"
