The news of the approval of the establishment of the Zhongxin Company Publishing House made Li Zhongxin feel very excited.

Li Zhongxin knew very well that after the establishment of the publishing house, the distribution of domestic comics by Zhongxin Company and the fact that he would have to find experts and scholars to find some translators and writers of modern practical technical reference books would soon be realized.

Li Zhongxin not only wants to engage in practical technical reference books, but also wants to engage in some practical books on the frontiers of science and technology.

The construction of scientific research laboratories in Jiangcheng is for the purpose of upgrading science and technology, and spreading these cutting-edge technologies in the form of books will allow more people to see cutting-edge science and technology, and will also make people have more innovative consciousness and innovative ideas.

At this time, the state has not paid enough attention to the practical technology of the reference book, an enterprise wants to obtain technological transformation and upgrading, basically just wait to rely on, only the state or the superior leaders find new practical technology, or from foreign countries to introduce advanced technology, will carry out technological upgrading.

It is difficult to upgrade the enterprise, and it is even more difficult for some people who want to start a business or start a small factory to obtain technology, because few publishers publish such a book series.

Li Zhongxin felt that after the establishment of the publishing house of Zhongxin Company, he would find some people of insight to develop a series of books dedicated to technological innovation and production technology.

In terms of this kind of book series that Zhongxin Company is engaged in, it must be able to be understood by people with some culture.

For example, the machining process, which is the backbone of China's manufacturing industry in the future, can only be made into fine machines by processing fine qualified parts.

The machining process is the process of manufacturing and processing the workpiece or parts, and the process of directly changing the shape, size and surface quality of the blank by using the method of machining is called the machining process.

For example, the processing process of an ordinary part is rough machining - finishing - assembly - inspection - packaging, which is a general process of processing.

Machining technology is to change the shape, size, relative position and nature of the production object on the basis of the process to make it a finished or semi-finished product, which is a detailed description of each step and each process.

For example, as mentioned above, rough machining may include blank manufacturing, grinding, etc., and finishing may be divided into turning, fitters, milling machines, etc., and each step must have detailed data, such as how much roughness should be reached, and how much tolerance should be reached.

According to the number of products, equipment conditions and the quality of workers, technical personnel determine the process to be adopted, and write the relevant content into process documents, which are called process regulations.

In general, the process flow is the program, the processing technology is the detailed parameters of each step, and the process specification is the specific processing technology written by a factory according to the actual situation.

In the seventies and eighties, whether it was a turner or a fitter, the masters in these factories only taught their apprentices the technical processes and methods, and there were few systematic books that explained and distinguished these things in detail.

Once this kind of book is successfully printed, it will be of considerable help to China's mechanical processing talents, and will also contribute a lot to the rise of China's manufacturing.

People in this era are generally taught by word of mouth or by hand, and they always have the idea that the apprentices of the church starve their masters to death, and it is precisely because of this reason that China's development in various industries is quite slow.

These books in the machining category, starting from the most simple and easy-to-understand introductory knowledge, all the way to how to grind the alloy cutter head, how to fix the parts on the chuck, and gradually deepen, by reading these practical technical books, young people who have just joined the processing plant can quickly grasp the tricks.

Under normal circumstances, it takes nearly three years for an apprentice to be able to produce an apprentice, but with these auxiliary reference books, under the guidance of the master, it will take almost a year and a half to be able to produce an apprentice, so that the country's mechanical processing products can quickly achieve quantitative and qualitative changes.

The kind of books that Li Zhongxin wanted to engage in were quite different in nature from those books that were talked about in general terms and did not have much use, and he was going to systematize these processes and techniques, and find some old lathe masters with very good craftsmanship in Jiangcheng to record the details of their work.

Most of the knowledge in the books is equivalent to the mode of word of mouth, that is, by reading these books, to a large extent, it is equivalent to the lathe master in the workshop teaching it on the side.

Another example is heat treatment technology in the processing process.

Heat treatment is a metal thermal processing process that heats, insulates and cools metal materials in a certain medium, and controls their properties by changing the metallographic structure on the surface or inside the material.

The development of metal physics and the transplantation and application of other new technologies have made the metal heat treatment process more developed. A significant progress was made in 1901~1925, when the rotary drum furnace was used for gas carburizing in industrial production.

In the 30s, the dew point potential difference meter appeared, so that the carbon potential of the furnace atmosphere was controllable, and later the method of further controlling the carbon potential of the furnace atmosphere was developed with carbon dioxide infrared meter and oxygen probe.

In the 60s, the heat treatment technology used the role of plasma field to develop the ion nitriding and carburizing process; The application of laser and electron beam technology has enabled new surface heat treatment and chemical heat treatment methods for metals.

The emergence of these technologies has changed the surface or internal structure of metal materials, making the structure of lathes and other processed structures more durable and durable.

In China, in the 80s, there were only a few large factories with heat treatment workshops, and this technology was not widely spread.

Once the domestic and foreign heat treatment technology published by Zhongxin Company appears, it will accelerate the process of heat treatment process in China.

Whether it is a professional in heat treatment or a young employee who has just arrived in the heat treatment workshop, they will learn some advanced experience from it.

After the appearance of this kind of book in each heat treatment workshop, it will play a role in promoting the upgrading of these workshops in the future.

Under normal circumstances, according to the heat treatment process in China at this time, what is the hardness that can be achieved, and through simple upgrading, or changing the process, or developing the operation in the same state, then these parts in China will be improved a lot.

These things are all mechanical processing things, which are the top priority of the country's future development.

Li Zhongxin felt that he had the need and also had such an awareness to accelerate the process of China's mechanical technology.

If the domestic machining technology can develop rapidly, it will also be of great help to the future development of Zhongxin Company.

In the future, Tadashin will manufacture automobiles, and the various processes and technologies required to manufacture automobiles will be published by Tadashin.

If the parts that can meet the requirements of automobiles can appear in China as soon as possible, the automobile industry of Zhongxin Company will also be able to develop rapidly.
