The news that Zhongxin Company Publishing House was approved for establishment made Li Zhongxin very excited.

Li Zhongxin knew that after the establishment of the publishing house, the distribution of Zhongxin Company's domestic comics and his need to find experts and scholars, as well as some translators to write modern practical technical reference books, would soon be realized.

Li Zhongxin not only wants to produce practical technical reference books, he also wants to produce some practical books on cutting-edge science and technology.

Zhongxin Company built a scientific research laboratory here in Jiangcheng for the purpose of technological upgrading. By disseminating these cutting-edge technologies in the form of books, more people will see cutting-edge technologies, and it will also increase people's awareness of innovation and innovative ideas.

More.

At this time, the country has not paid enough attention to practical technology reference books. If an enterprise wants to obtain technological transformation and upgrading, it basically has to wait and see. Only the country or superior leaders discover new practical technologies, or introduce them from foreign countries.

Only after advanced technology has been introduced will technological upgrades and transformations be carried out.

There are many difficulties in upgrading and transforming enterprises, and it is even more difficult for those who want to start a business or run some small factories to obtain technology, because few publishing houses will publish such a series of books.

Li Zhongxin felt that after the establishment of Zhongxin Company's publishing house, he would find some knowledgeable people to produce a series of books specifically introducing technological innovation and production technology.

This series of books produced by Zhongxin Company must be understood by people with some literacy.

For example, machining technology will be the backbone of China's manufacturing industry in the future. Only by processing fine and qualified parts can we make fine machines.

The machining process is a step in the manufacturing and processing of workpieces or parts. The process of using machining methods to directly change the shape, size and surface quality of the blank to turn it into parts 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.

Mechanical processing technology is based on the process, changing the shape, size, relative position and properties of the production object, etc., to make it a finished product or semi-finished product. It 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 machining may be divided into lathes, fitters, milling machines, etc. Each step requires detailed data, such as how much roughness to achieve and tolerances.

How much to achieve.

Technical personnel determine the process to be adopted based on the quantity of products, equipment conditions, and quality of workers, and write the relevant content into process documents. This document is called a process procedure.

In general, the process flow is the outline, the processing technology is the detailed parameters of each step, and the process schedule is the specific processing technology written by a factory based on the actual situation.

In the 1970s and 1980s, whether they were lathes or fitters, the masters in these factories only taught their apprentices technical techniques and methods. There were few systematic books that explained and distinguished these things in detail.

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

People in this era usually teach by word of mouth or step by step. They always have the idea that the disciples will starve to death. It is precisely for this reason that China is developing at a very fast pace in various industries.

slow.

These books in the mechanical processing category start with the simplest and easiest-to-understand introductory knowledge, and then go on to how to grind the alloy tool head and how to fix the parts on the chuck, and gradually deepen. By reading these practical technical books, I just joined.

Young people working in processing plants can quickly master the tricks.

Under normal circumstances, it takes nearly three years for a lathe apprentice to become an apprentice, but with these auxiliary reference books and the guidance of the master, it can take almost one and a half years. In this way,

It will allow the country's mechanical processing products to quickly achieve quantitative and qualitative changes.

The kind of books Li Zhongxin wanted to create were quite different in nature from those books of later generations that were of little use in general terms. He planned to systematize these crafts and techniques and find some in Jiangcheng.

The old lathe masters, who are very skilled in craftsmanship, record some details of their work.

Most of the knowledge in the book is equivalent to the oral transmission mode. In other words, reading these books is, to a large extent, equivalent to being taught by a master lathe in a workshop.

Another example is heat treatment technology in processing technology.

Heat treatment is a metal thermal processing process that places metal materials in a certain medium for heating, insulation, and cooling, and controls its properties by changing the surface or internal metallographic structure of the material.

The development of metal physics and the transplantation and application of other new technologies have enabled greater development of metal heat treatment processes. A significant development was the application of rotary drum furnaces for gas carburizing in industrial production from 1901 to 1925.

In the 1930s, the dew point potentiometer appeared, which made the carbon potential of the furnace atmosphere controllable. Later, methods for further controlling the carbon potential of the furnace atmosphere were developed using carbon dioxide infrared meters, oxygen probes, etc.

In the 1960s, heat treatment technology used the role of plasma fields to develop ion nitriding and carburizing processes; the application of laser and electron beam technology also 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 structures processed by lathes and other machines stronger and more durable.

In China in the 1980s, only a few large factories had heat treatment workshops, and such technology was not widely spread.

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

Whether they are professionals in heat treatment or young employees who have just arrived in the heat treatment workshop, they will learn some advanced experience from it.

After this kind of book appears in various heat treatment workshops, it will play a role in promoting the upgrading and upgrading of these workshops in the future.

Under normal circumstances, according to China's heat treatment process at this time, what is the hardness mark that can be achieved, and through simple upgrades, or changing the process, or developing operations under the same conditions, then China's

These parts have improved a lot.

These things are all related to mechanical processing and are the top priority for the country's future development.

Li Zhongxin felt that he had the need and the awareness to accelerate the progress of China's mechanical technology.

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

Zhongxin Company will manufacture cars in the future, and Zhongxin Company will also publish the various processes and technologies required to manufacture cars in the future.
