Traveling through the sword to engage in military industry.

Chapter 124 T68 Boring Machine Launched
After completing the smelting and chemical basic factories, Ren Zhong placed his focus on the production of machine tools. As a universal industrial mother machine, the 6140 lathe has been continuously copied by Ren Zhong. There are now two in Yangcun, one in the arsenal at the base headquarters, and the fourth will be built in the Nangou branch factory, which has already started the casting model manufacturing stage.

This lathe will be the main machine tool throughout the 1940s. It will be widely used in the border areas in the next few months and become the number one mechanical processing force of border research institutions!
The next important thing to solve is the widely used boring machine. The boring machine is general and versatile. It is suitable for machining small and medium-sized parts with high processing precision or more precise hole spacing requirements. It can bore, drill, expand holes, ream holes, mill planes, and turn internal threads.

If you don't understand these abstract concepts, then let's take two examples to make you understand its importance. The world's first real boring machine was invented by Wilkinson in 1775. In fact, Wilkinson's boring machine is a drilling machine that can precisely process cannons. It is a hollow cylindrical boring bar with both ends mounted on bearings.

The production of gun barrels and even the subsequent production of seamless steel pipes cannot avoid the development of boring machines.

The second use is that boring machines are indispensable for manufacturing cylinders and pistons for steam engines, diesel engines, and gasoline engines.

These two uses will be the important cornerstones for Renzhong to further develop industrialization. In the future, the production of mechanized products such as automobiles, motorcycles, tractors and even tanks will require the development of boring machines.

Ren Zhong found the easiest boring machine to replicate in the main world, the T68 horizontal boring machine. This boring machine, which is known as the first boring machine in New China, is very well-known. Due to its wide influence, Ren Zhong found its complete set of design materials without much effort, including core materials such as electrical design drawings.

This meant that this boring machine had no secrets for Ren Zhong. According to the design drawings, Ren Zhong still asked Chengxin Machinery Processing Factory to complete the production and processing of the core key components first. This antique thing was no problem at all for two level 8 fitters, and these components were completed in less than a week.

Including the processing of the electrical parts, these simple circuits were easily completed by two fitters looking at the drawings. After Ren Zhong asked a few questions, he found out that these two level eight fitters both had experience in repairing this boring machine!
It turned out that I met an "old acquaintance" again.

With the help of three eighth-level fitters in Jincheng, Ren Zhong has not encountered any technical bottlenecks in replicating these ancient machine tools.

The more troublesome ones are the dual-speed motor and the fast-moving motor, so Ren Zhong had to honestly copy the core part of the motor from the main world and then bring it to the Bright Sword world for assembly.

After all, in casting production, Yangcun has already started to have the first batch of skilled workers who can make casting models much faster than before.

Once you have learned this, you will be a skilled worker. It is completely different from the first time when you have to redo the work with bumps and bruises. The production pace can be maximized. In addition, people of this era all consciously and voluntarily adopt the 007 work pace, and no one works less than 12 hours a day!

Usually they have to work for 18 hours before they are forced to take a break.

Especially in Yangcun where Li Yunlong was supervising.

In Nangou, after Ren Zhong had more than 20 qualified tool workers, there were a large number of people who could solve various questions for the workers, and the project pace and work saturation were maximized.

The 6140 lathes and T68 machine tools are both used for casting molding. As for the manual punching machines, they are now produced in Yangcun and sent to Nangou, so that the bullet production factory in Nangou can be opened first.

Half of the goods that Ren Zhong brings every day now need to be brought in zinc, so that the pure copper produced in Nangou can be directly refined into brass. There is no need to wait for the molten copper to solidify and then be reheated, which can also save smelting time.

Day after day of hard work finally paid off a month later. All the castings of the boring machine were successfully cast. For this new machine tool, Gao Kaiming came all the way from Yangcun with several of his disciples, ready to witness the birth of the first boring machine.

"Xiao Yun, has the motor assembly and testing been completed?" Ren Zhong was also a little excited. He brought all the people in the chemical class who were not on duty early in the morning, preparing to let them all see the assembly of the boring machine and have a valuable practical experience. The motor is a component of the two worlds. The permanent magnet, silicon steel sheet, coil, etc. are brought from the main world, but the motor housing and other parts of the casting are produced in the Liangjian world.

Xiao Yun is the most knowledgeable student in the class. He is an intellectual with two years of college life under his belt. He is entrusted with important tasks by Ren Zhong and is the monitor of the chemical engineering class. However, Ren Zhong provides Xiao Yun with a lot of training and advice on many things.

Assembling the motor was an opportunity that Ren Zhong gave Xiao Yun to try out the machine.

"Mr. Ren, it's assembled and tested and everything is good!" Xiao Yun was even more excited.

Today, these people will witness new history again. Over the past month, these students have been completely impressed by Ren Zhong. Many things that are regarded as miracles by outsiders were completed with their participation!

Even though most of them still don't understand the principles behind it, they have all recorded their learning notes and experiences on how to achieve it. According to their current learning status, they can be the main force in supervising and guiding the construction of sulfuric acid production lines and steel smelting production lines.

The mechanical knowledge that we are learning now is pure free money, so everyone is more enthusiastic than others in learning.

"Boss Ren, I'd better come to Heyuan to learn more from you," Gao Kaiming saw a pile of spare parts in front of him. Even though most of them were unfamiliar, it still couldn't stop his enthusiasm in this regard. "It turns out that our factory has a boring machine, but the control is very strict, and the workers who use the boring machine are strictly separated.

Even those who use boring machines can hardly describe what they look like, let alone know the structure inside. When the foreigners are repairing this machine, they lock the door and don’t let anyone see it.”

Gao Kaiming used to work in the arsenal, so he was naturally very strict about the use and management of various equipment. These important equipment still have confidentiality value even now.

Therefore, even though Gao Kaiming had worked as a workshop director, it was normal that he had never seen a boring machine. In other arsenals, every link was relatively closed for fear that the technology would be leaked out.

"That won't work. Your job is also very important." Ren Zhong shook his head. Yangcun is a big industry, and it would be even worse if there is no leading figure to drive the mechanical processing.

Now the key is to inspire their enthusiasm.

"Both sides are important. With the support of Gao Gong, Yangcun has now doubled its weekly production capacity of guns and ammunition. These are things that the troops urgently need, and we must provide good services over there." Ren Zhong rejected Gao Kaiming's idea.

"But if you can come here for a few days every month and learn some new things from me in advance, I think it is still meaningful."

Ren Zhong rejected Gao Kaiming, but did not completely reject him.

For example, at this moment, Gao Kaiming and his colleagues have the opportunity to come here and learn to assemble a new boring machine on site.

They can brag about these experiences for the rest of their lives!
