The C620-1 ordinary lathe is the first ordinary lathe produced by New China, which is a milestone in the history of Chinese industry. It was successfully developed and put into production by Shenyang No. 1 Machine Tool Factory in August 1955, and is known as a classic among "industrial mother machines". Name meaning The model code of C620-1 has its own meaning: - C — stands for lathe - 6 — refers to floor-standing horizontal - 20 — main parameter, the maximum rotation diameter of the bed is 400mm - 1 — indicates the first improvement Main specifications and performance - Processing capacity: The maximum turning diameter on the bed is 400mm, and the maximum turning diameter on the tool holder is 210mm - Thread processing: It can process 43 kinds of metric threads with pitches from 1 to 192mm, 20 kinds of inch threads with 2 to 24 teeth per inch, 38 kinds of module threads with modules from 0.50 To 48, and 37 kinds of pitch threads from 1 to 96 - Functional scope: capable of completing various processes such as turning cylindrical stepped shafts, boring, grooving, and end face turning - Transmission mode: driven by motor, all mechanical transmission is used, and the main spindle box lubricating oil is supplied by an oil pump - Structural features: The headboard is equipped with a multi-plate friction clutch, and the front bearing of the spindle is a special double-row ball bearing that can be adjusted; there is a drop worm in the slide box to prevent damage to the tool feeding system; the bearings of each axis can be adjusted outside the box without disassembling parts Historical status and contribution - The output is astonishing: in the 1950s and 1960s, the annual output of C620-1 reached more than 2,200 units. By the 1960s, the annual output exceeded 4,000 units, accounting for more than 80% of similar products in the country. The supply was in short supply for a long time, and it was even exported abroad - Excellent precision: the machining accuracy reached the world level at that time, and was not inferior to the Japanese machine tools that were widely used in domestic factories at that time - Widely used: widely used in mechanical processing in steel plants, mines, railways and other industries. In 1958, Shenyang Water Pump Factory used it to produce the first high-pressure boiler feed pump rotor components in New China - Boarding the RMB: To commemorate its historic contribution, the obverse pattern of the third set of RMB 2-yuan banknotes in 1960 is the scene of a lathe worker operating a C620-1 lathe, so this banknote is called "Two Yuan Lathes" Current situation Today, the C620-1 lathe has become the treasure of the China Industrial Museum (located in Tiexi, Shenyang), telling the public the story of the struggle of New China's industry from scratch.

◣S195 Diesel Engine Introduction S195 is one of the most classic and widely used single-cylinder small diesel engines in China. It is known as the "magic engine of the generation". It has been in service for more than half a century since its advent in the 1960s, and it still plays an important role in the field of domestic agricultural machinery. ◣R&D History and Honors S195 was born in Changzhou Diesel Engine Factory in the 1960s. It was jointly developed by Changzhou Diesel Engine Factory, Shanghai Internal Combustion Engine Research Institute and Jiangsu Institute of Technology. This model has won the following important honors: 1978: National Science Conference Science and Technology Achievement Award 1980, 1982, 1988: National Product Quality Gold Award "Lushan Brand" S195 produced by Jiujiang Power Machinery Factory Won the National Quality Product Silver Award (1985) and was selected as the national "Seal of the Republic" witness in 2024 ◣Main supporting equipment and applications S195 has an extremely wide range of applications, covering almost all scenarios that require small and medium power: Agricultural machinery: walking tractors, small four-wheel tractors, rotary tillers, threshers Drainage and irrigation equipment: small water pumps, irrigation and drainage units Power generation equipment: small diesel generator sets (such as 10kVA units) Ship power: small inland river marine units Industrial equipment: air compressor units Processing of agricultural and sideline products: rice mills, flour mills, feed crushers, etc. ◣Market position The S195 series is the "golden power" in rural areas of China. According to relevant literature, the number of units in the country's society once reached 20 million units. It is the most widely used single-cylinder diesel engine in China. After the reform and opening up, with the implementation of the rural joint production contract responsibility system, the walking tractor equipped with the S195 has greatly promoted the transformation of Chinese agriculture from manual farming to mechanized operations.

S195 generation artifact

CA6110 is an in-line six-cylinder, four-stroke, water-cooled, direct-injection diesel engine series independently developed by China FAW Group (FAW). It is also one of the earliest domestic medium- and heavy-duty vehicle diesel engines to be installed on a large scale in China. The meaning of the model is very straightforward: CA = FAW (Changchun) code, 6 = six cylinders, 110 = bore 110 mm. Its core specifications are: ◣Origin and status Around 1978, FAW introduced a Japanese diesel engine prototype for experimental research through a "combination of technology and trade" method, and decided to develop its own diesel engine for Jiefang trucks (at that time, due to domestic fuel policy restrictions, small and medium-sized vehicles mostly used gasoline engines). The finalization was completed in 1985 and installed on the second-generation Jiefang CA141 in 1986, ending the history of "Jiefang only has gasoline engines". The initial production tasks mainly fell on Dalian Diesel Engine Factory (Dachai). Later, Wuxi Diesel Engine Factory (Xichai) also went into production and became the main force in subsequent development. Since then, it has been derived from many versions of supercharger, supercharger and intercooler, as well as those that meet the National II and National III emissions, and has become the basic platform of Xichai's "Hengwei/Kangwei" series. The market share once reached one million units, and it was the main driving force for China's medium-sized trucks and medium-sized passenger cars from the 1990s to the 2000s. ◣Technical features Simple structure and good maintainability: cast iron body, gear transmission, independent cylinder head (some versions), easy to disassemble and assemble, low requirements for oil and maintenance conditions, cheap accessories and can be repaired everywhere - this was its core competitiveness at the time. Good low-speed torque and large torque reserve: The supercharged version has a torque reserve coefficient of up to 20% to 30%. It has strong adaptability to full load climbing and sudden load changes, and is very suitable for the road conditions and overload conditions at the time. One machine for multiple purposes: Through speed regulator (R801, RSV or electronic speed regulation), supercharger and calibration matching, the same platform can cover multiple uses such as trucks, buses, loaders, combine harvesters, generator sets and construction machinery. The shortcomings are also obvious: the two-valve + mechanical pump results in low power, high fuel consumption, noise and vibration levels; in the early days, there was no intercooling and no after-treatment, and the emissions were only equivalent to Euro I/National I levels. Later, they relied on intercooling, EGR, and electronically controlled pumps to barely follow the National III standards, and were eventually replaced by new platforms such as 6DF and 6DL (Aowei).

The author recommends that the protagonist be promoted and transferred to Hechai to build a factory, so that the protagonist can take the lead and become a member of the academic department. At the same time, he should pay attention to international intellectual property rights and apply for international patented technologies through Hong Kong. The Huo family is an agent for the export of various diesel engines and agricultural machinery Create China Cummins and MTU In the 1960s, the military power 150HB series diesel engines, 6V armored vehicles, 8V, and 12V main battle tanks were developed. Various engineering diesel engines CHD620 series diesel engines for submarines, various low-speed, medium-speed and high-speed marine diesel engines Develop various gasoline engines and gearboxes at the same time

At that time, all walks of life were choked by power. The main focus was metallurgy, and the power industry was fine. The stall should not be too big, including various diesel engines, gasoline engines, aero engines, and gas turbines.

Don't make conflicts between people a slap in the face. The most important thing about industrial writing is to write a unified style of writing. If you write about infighting and can improve your technology, it will only show that everyone is an Indian who relies on the system instead of an independent and self-reliant new Chinese. Writing about infighting will only show that you have no control over the plot and can only rely on gambling agreements to cut your way up.

In 1955, with an annual output of 970,000 tons, the Karamay No. 1 Well blew out oil. In 1956, the annual output was 1.16 Million tons, exceeding 1 million tons for the first time. In 1958, the annual output was 2.26 Million tons, a year-on-year increase of 54.8%. In 1959, the Daqing Oilfield was discovered with an annual output of 3.73 Million tons, a year-on-year increase of 65%. In 1960, the annual output was 5.2 Million tons. Daqing Oilfield was put into development, and the production capacity increased by 1.47 Million tons compared with last year. In 1965, the annual output was 11.31 Million tons, achieving self-sufficiency in all petroleum products. In 1969, the annual output was 21.74 Million tons, breaking the 20 million tons mark. In 1970, the annual output was 30.65 Million tons, breaking the 30 million tons mark, a year-on-year increase of 41%. In 1973, the annual output was 53.61 Million tons, breaking the 50 million tons mark. In 1975, the annual output was 77.06 Million tons, breaking the 70 million tons mark. In 1978, the annual output was 104 million tons, breaking the 100 million tons mark. In 1985, the annual output was 125 million tons, breaking the 120 million tons mark. In 1993, with an annual output of approximately 147 million tons, it began to become a net oil importer. In 2000, the annual output was 163 million tons, the oil gap continued to expand, and oil imports continued to this day. From 1955 to 2000, China's annual crude oil production jumped from 970,000 tons to 163 million tons, an increase of nearly 168 times in 45 years. Behind this process is the relay development of dozens of oil fields such as Karamay, Daqing, Shengli, Liaohe, Changqing, etc. It is also a complete microcosm of the transformation from an "oil-poor country" to a major oil country and then to a major energy consumer.

Everyone has conflicts with the protagonist, and people are looking for trouble wherever they go. It's really interesting.

In 1956, which one was more popular, technical secondary school students or high school students? Students from technical secondary schools are more popular, and the core reasons are as follows: Students from technical secondary schools will be employed immediately, while their future in high school is uncertain. After graduating from technical secondary schools, students are directly assigned jobs by the state, obtain cadre status, and enter institutions, state-owned enterprises, schools, hospitals and other units, which is a real "iron rice bowl." Although the enrollment rate of high school students was extremely high, it was not 100% after all. Those who did not advance to higher education may have to join the army, become apprentices in factories, or even work in the countryside. Their futures are not as certain as those of technical secondary school students. The treatment of technical secondary school is better than that of high school. In 1956, the State Council clearly stipulated that the salary of ordinary high school graduates should be lower than that of graduates of secondary vocational schools of the same academic level.      ，，      Vocational secondary school students are required to apply for "agricultural-to-non-agricultural transfer" when they enter school, converting their rural household registration into an urban commodity grain household registration, with free tuition and living allowances. This is a life-changing event for rural families. Technical secondary schools are "selecting the best from the best". At that time, students with the best grades among junior high school graduates often preferred to apply for technical secondary schools because the admission quota was limited and the score line was high. In some places, there was even a phenomenon of "cannot get into technical secondary schools before going to high schools." However, it should also be noted that if high school students can enter college, they will have greater room for development in the long run - college graduates will be assigned to state agencies, scientific research institutes or key enterprises, and will have a higher social status. So to be precise: in the short term, technical secondary schools are more popular (high certainty and good remuneration), while in the long term, high school students have a higher upper limit (if they can go to university, they have a bright future). But in the "talent-hungry" era of 1956, technical secondary school students who could secure a steady job were indeed the "hot potato" in the eyes of most families.

They are all rubbish novels. If you don't cheat, you will die.

No need to try, it's just bullshit!

What is most needed for machine tool tractor processing equipment is actually the improvement of steel productivity and the reuse of lean iron ore tailings. The grade of iron ore in New China is mostly around 30, which is too low from the minimum standard of 60 for blast furnace ironmaking and requires multiple processes. The reuse of tailings was proposed by powerful people who returned to China in the 1950s. It was not until about 2010 that smart mineral processing technology actually started to be used in factories because the standards required for intelligent mineral processing technology were too high. From the 1980s to the 2000s, production capacity soared. This is because the fertilizer industry and the steel industry have finally obtained enough resources and technology. The technology that the protagonist can currently improve is actually chemical technology. Whether it is bacterial beneficiation technology, potato saccharification technology, new fertilizer or medium-pressure fertilizer refining technology, they can all be developed with the technology of the 1950s by relying on luck and systematic efforts. The biochemical industry that only needs to import a small amount of high-precision equipment is the place where cheating can be done legally and reasonably.
