Of course, there are also watches produced in China, but in terms of the number of parts, it is not comparable to this watch, the more parts mean that its failure rate is higher, but the laborer is known for its accuracy, so it shows that its technology is more advanced, and the texture of the material is also better.

However, as Liu Lang patiently spent half an hour disassembling the watch, the position and shape of each part were firmly remembered by him.

But this is definitely not to say that Liu Lang can completely imitate this watch now, even if it is imitated, this watch can never be compared with laborers, the key lies in the defects in materials and processing technology.

There is no doubt that the material used in this Labour watch is mostly steel, in addition to gold, which is called stainless steel and does not rust when exposed to water.

Stainless steel has been widely used after more than 20 years, even if the kitchen knives used by ordinary people to cut vegetables are made of stainless steel, but in the early eighties, there are few factories in the whole country that can produce stainless steel.

Liu Lang read in the book, in fact, as early as the early 60s, Shanghai Iron and Steel at that time used the return oxygen blowing method to smelt stainless steel. In 1961, Shanghai Iron and Steel Co., Ltd. produced the first stainless steel pipe blank produced in China on the domestic 76mm two-roll oblique rolling perforator, and successfully trial-produced China's first aviation stainless steel pipe that was completely localized from raw materials to finished products.

Since then, China's stainless steel production has begun to develop gradually, but for various reasons, for a long period of time, the development of stainless steel is almost standing still, and the stainless steel produced can only be used in the aerospace industry.

Liu Lang's grandfather has a watch, which he bought for more than 100 yuan five years ago, and it is made of all-steel, but unfortunately he is afraid of getting wet, and he should wipe it clean quickly if it gets wet, otherwise it will rust.

Workers watches obviously do not have such a problem, and it is clear that stainless steel has been widely used in Western countries.

In addition, the grinding level of this watch is also very high, and there is no corresponding machine tool in China that can grind such smooth and tiny parts.

In 1980, the state had a statistic on the status quo of the machine tool industry, when the national machine tool owned 2.83 million units, of which the proportion of rough lathes was 60%, and the finishing grinding machine accounted for less than 10%, and the reason for the backward technology was that there were more rough machine tools and fewer finishing machine tools.

For example, the bearing factory where Liu Donglai came to work, the machine tools used in the factory are still the most primitive centerless grinders, double-end grinders, Roll grinder, this machine tool was born in the twenties, the precision is very low, generally less than one or two centimeters of steel balls can not be grinded, and in the whole country, the highest technology grinding machine accuracy is only to the millimeter level, and foreign 70s has been manufactured using microprocessor digital control and adaptive control technology of grinders, the accuracy has reached the micron level, the country and the Western countries compared with the country, the gap in technology can be described as a world of difference, needless to say anything else, is the smallest gear in this watch is only two or three millimeters in size, this tiny part is also covered with patterns, simply thinner than a hair, apparently, they are all polished by CNC machine tools.

Liu Lang consulted materials in the library of Huaxia University and saw that in the 60s, there was a "precision machine tool battle" in the country, and the second machine of the capital took the most advanced cylindrical grinding machine abroad at that time as the goal of catching up, and successfully developed and processed the cylindricity to reach 1~2 microns, the finish of 14 MG1420 high-precision grinder, this machine tool is known for its high-precision coordinate boring machine, as a result of a catastrophe ensued, the machine tool was regarded as a product of capitalism was miscellaneous, designers were also regarded as the comprador of capitalism in the country, under the cowshed of the cowshed, criticized by the fight, there are not many people who have survived until now, as for all kinds of technical parameters, they can't find it.

It is ridiculous to say, in the fifties and sixties, the country put forward the slogan that "the machine tool is called the working machine of the machinery industry, and it is the "chief technologist" to promote the development of the machinery industry. There is almost no development in the research and development of tools, and the country also lacks careful planning, which is out of touch with the development of the host, and the second is a serious lack of technical experts and skilled technical workers, in the precision, quality, and reliability of the product, the technology is not too hard, and the supporting facilities are not good.

If you want the country to become an industrial power, materials and machine tools are fundamental, and if these two things are not good, any engine is in vain.

In addition, there is also the cultivation of talents, Xiong Huaizhi once studied in Germany, where he saw that the key types of work and assembly and debugging technicians in the factory are over 50 years old. The old technician with stunts, the reason is very simple, the machine tool industry has no decades of experience is not able to train a qualified technician and technician, and in the country, even after twenty or thirty years, an old worker to the fifties or retired or transferred to the leader, the reason, or due to personal complacency, or do not understand the market demand, or the idea of fame and fortune, or because of some irresistible temptation, quick success, opportunistic, the result has caused a great waste of talent!

Engineering talents are to rely on "stupid kung fu, endure loneliness", eliminate an unreliable factor, incorporate the results into the design, process, manufacturing process into the standard, strict implementation, and then get feedback from practice to improve, and finally accumulate a lot of valuable data, this is the most valuable experience, but also the core strength of an enterprise, this aspect of the country is much worse.

The country is not short of talents, some people even have to exceed the foreign professionals in the same industry, even if they have not learned a lot of related majors, such as the control system of CNC machine tools, which requires a large number of computer-related talents, and the country does not even have a few computers, but under this seemingly impossible condition, at the end of the 50s, we and the world synchronous research and development of CNC systems, its performance is not much lower than similar foreign products.

Just as the country in order to engage in nuclear bombs, relying on a group of people to hold an abacus can shock the world, the Chinese people can always create miracles under the impossible, such as Liu Lang found some information in the library, in the fifties Shanghai Machine Tool Factory a comrade named Zhou Qin served as the director of the Shanghai Machine Test Research Office, his education is not the highest, just graduated from secondary school, but the level is very high, put forward a very advanced suggestion at that time, such as using tape frequency division instead of the transmission chain, so that the speed ratio of the workpiece can be changed arbitrarily, which is the worm grinding wheel grinding, Gear processing machine tools have revolutionary significance, this research has reached the world's advanced level, but later, the expert also suffered a series of criticism, and finally died tragically, such an outcome is a pity.

Liu Lang saw from a watch that the country's huge backwardness in machinery manufacturing, capital, talents, technology, nothing, to make up for these weaknesses is not easy!
