Coincidentally, a few years ago, a private enterprise in China wanted to introduce an automatic production line for rechargeable batteries from Japan. The Japanese lion opened its mouth and offered a price of 20 million US dollars. This private enterprise could not get so much money, even if it was found in the production cost. It will also lack competitiveness, and it will be subject to Japanese people in the automatic production line maintenance and spare parts supply, and it will be at the mercy of the Japanese. However, the private enterprise CEO found in Japan that most of the automatic production line can be manually operated, and the Japanese labor force is expensive, so the machine replaces the labor. And China’s surplus of labor, even college students are hard to find a job, why not manually replace the machine. The high-profile he proposed is to build a production line that mixes machines with manual operations on the basis of the decomposition of automatic production lines. A few high-end equipments necessary for the production line are imported from abroad. For most low-end and medium-end equipment, low-cost domestic equipment is mainly used. No manual work is required for the machine. In the operation staff, high, medium and low collocation is implemented, that is, a small number of college students are recruited to operate a small number of high-end imported equipment, and a group of skilled workers are mainly engaged in the operation of domestic low-end equipment, and then recruit a large number of migrant workers to train for a certain The manual operation of the process resulted in the construction of a production line with automatic, semi-automatic and manual operation of rechargeable batteries for less than US$5 million. This Chinese-style production line makes the proud Japanese people sigh. The structure of this mixed production line is 10% for high-end college students, 20% for mid-level technical workers, and 70% for low-end migrant workers. It saves a lot of (medium and high-end) labor costs and also forms high, medium and low. The orderly matching of class operators creates a large number of employment opportunities for low-end migrant workers. This is also a “high-low-low†production mode or employment mode, which is similar to the Shenyang Machine Tool Group's sequential assembly mode. The hero sees the same. Shortly after the low-cost hybrid production line was put into production, Japan's similar products were squeezed out of the domestic market. One year later, the fully automatic production line of the Japanese company was discontinued and the market was withdrawn.
The sorting assembly of Shenyang Machine Tool Group is said to be a specialized division of production mode similar to the assembly line. “High belt and low belt†is a production mode or employment mode featuring specialized division of labor. The specialization of the division of labor in human society is developing rapidly, and the division of labor is becoming more and more detailed. In the final analysis, specialized division of labor is conducive to improving efficiency, employing people and making the best use of talents. At the same time, the specialized division of labor can also enable ordinary employees and even low-end migrant workers to be competent for relatively complex tasks. For example, sequencing can enable low-end migrant workers to participate in complex machine tool assembly and allow migrant workers to replace some skilled workers. To alleviate the serious shortage of skilled workers, it can also create some middle-end and even high-end employment opportunities for the lowest-end and most difficult migrant workers, broaden the employment areas of migrant workers and increase their income.
Advantages of sorted assembly
There are two advantages to sorting assembly:
First, it can be "high with low." The assembly workshops of the various machine tool factories under the Shenyang Machine Tool Group are always a few skilled high-end skilled workers. In the past, only a few skilled workers were busy working overtime and singing a one-man show. Most ordinary workers were unable to make up because of lack of technology. A small number of people do, most people see, relying on only a few skilled workers, only one 30 machine tools are assembled in one month. Nowadays, the orderly assembly is carried out, so that most of the processes that can only be undertaken by a small number of skilled workers can be undertaken by ordinary workers with lower technical skills. Most ordinary workers are also as busy as skilled workers. From the past, there were only a few skilled workers. Everyone in the workshop is busy, and as a result, the efficiency of the sorting assembly is more than 20 times that of the previous one. Now it is no problem to assemble 1000 machine tools a month. The workers said in the image that the past is alive and waiting for people to live now.
Who is the higher the technology in the past, who is the busiest and most tired, always afraid of not completing the task. The current sorting assembly liberates a small number of skilled workers from most technically uncomplicated processes, allowing ordinary workers to undertake and make a few technologies. Skilled workers take advantage of their expertise and are primarily responsible for the most complex and critical processes, so that now a skilled worker is equivalent to the role of the last five or six skilled workers, which is equivalent to indirectly increasing the number of skilled workers by several times. It has largely alleviated the serious shortage of high-end skilled workers, enabling limited high-end skilled workers to play a greater role and can drive more low-end employees to work. This approach can be summarized as "high band and low."
Second, it is easy to recruit and train. Sequential assembly is actually a specialized division of labor, which simplifies the assembly of complex machine tools, so that ordinary workers can also handle some of the less technically demanding processes, and solve the common problems of ordinary workers in the past. In the past, due to the complicated assembly of machine tools and the high technical requirements for workers, enterprises usually only enter the graduates of technical schools. Nowadays, the society is full of “technical shortagesâ€. Many employers are rushing to graduate from technical school and recruiting graduates of technical schools. Increasingly large, and the price of technical school students is getting higher and higher, which makes the company a headache. However, the orderly assembly enables ordinary workers of average quality to replace high-quality technical school students to a considerable extent, and the recruitment and training of workers has become relatively easy.
Metallographic Microscope Series
The structure of optical metallographic microscope generally includes magnification system, optical path system and mechanical system, among which the magnification system is the key part. The preparation process of metallographic samples generally includes five steps: sampling, rough grinding, fine grinding, polishing and etching. The interception of samples from metallic materials and parts to be tested is called "sampling". Selection of sampling sites and grinding surfaces must be based on analysis requirements. The size of the sample is not uniform, from the perspective of easy to hold and grinding, the general diameter or side length of 15~20mm, 12~18mm high is suitable. For those too small, irregular shape and the need to protect the edge of the sample, you can adopt Mosaic or mechanical clamping method. For the inlay of metallographic sample, the appropriate size (about φ L5-20mm) of steel tube, plastic tube or paper shell tube is placed on the smooth plastic (or glass) plate, and the sample is placed in the tube to be ground face downwards into the filler, which can be solidified and hardened for a period of time. 3) Chamfering On the premise of not affecting the purpose of observation, the edges and corners on the sample should be ground off to avoid scratching the sandpaper and polishing fabric.
