Question 5: What is the importance of safe production (internship)? What should the fitter pay attention to in his internship? Matters needing attention during the internship are as follows: 1. Keep a clear head. No matter which professional internship, its salary will not be very high, and some even have no salary at all. In this case, what you need to do is to correct your mentality. After all, there will be no shortage of interns, unless you are excellent and can get the other party to pay your internship salary during the negotiation. If not, then you should study hard, learn more, learn all the knowledge you need and may use, and dig more from your internship, and don't waste several months of internship time. 2. Practice with your heart. As a college student, my self-study ability should be passable, just like when I went for an interview, HR asked: What do you think is the most important thing for you to study in our company? My answer is: I know there are many things to learn, but there is only one thing, that is, knowledge from books, because I can learn everything from books anywhere without going to your company. I can see that HR agrees with me. Similarly, as a college student, when you go to practice, you should study hard and learn everything you can't learn from books, which is often very important. As Cao Xueqin said: the world is clear, everything is learned, and people's understanding is an article. Society is the most complicated and excellent university, and it needs to be studied for a lifetime. During the internship, remember to take a notebook and pen with you at all times. I said your own, not that you would use it in public. Write down what you have learned and what you have learned at any time. Remember: good memory is not as good as bad writing. If you don't write it down in time, you may not remember what you want to remember after a day's work, so it is definitely your best choice to bring a small notebook with you. When colleagues talk about work, try to listen and participate in the discussion, even though you probably shouldn't speak in the discussion. As an intern, when colleagues (regular workers) in your company talk about their work, try to listen, especially in the same department or the department they want to go to in the future. Although there will be a lot of negative content in their conversation, there will also be a lot of good words, which will help you understand the industry information and be of great help to your future career choice and work. More importantly, it will make you contact and adapt to the complicated real life more quickly. Do more, not afraid of hard work. Working alone, the boss will prefer diligent and efficient employees. Don't be afraid of hard work during the internship, do all kinds of work well, help as much as you can, and have a comprehensive understanding of the work, which will be of great benefit to job selection and formal work. 4. Ask for advice with an open mind and study hard. For you who are still practicing, many things will not be normal. It's normal for your boss and boss to know that you can't do many things. If many people can, oh, congratulations, your ability will definitely surprise them! But if you don't ask what to do with an open mind, you will definitely disappoint them and lose the opportunity to enter the company directly after the internship. As for proper study, it is easier to understand. You know, college students are walking around now, and if they don't improve their ability, they will be out. Remember: when you stand still, you are already retreating! Your ability and social competitiveness are sailing against the current, if you don't advance, you will retreat! ! Of course, if you meet too many requirements, remember to say no! As the ancients said, a good bird chooses wood to live in, and a good minister chooses its master to serve. Now, even more so. If you really can't stay any longer, let's go There is no one here, but there is a place to live! ! ! During the internship, remember to make more friends and get on well with colleagues. There are many friends and many roads. Don't forget, a hero and three gangs should be your friends and frequent contacts. Maybe you will need his help in the future, or he will need your help.

(1) Flexible machining. When it is not suitable for machining, especially when maintaining mechanical equipment, locksmiths can get satisfactory results. (2) Parts with complex shapes and high precision can be processed. Skilled fitters can process parts that are more precise and smoother than those processed by modern machine tools, as well as parts with very complex shapes that even modern machine tools can't process, such as high-precision measuring tools, templates, and molds with complicated beginnings. (3) The tools and equipment used for small locksmith processing are cheap and easy to carry. (4) Low production efficiency and high labor intensity. (5) The processing quality is unstable, which is affected by the technical proficiency of workers. 3. The fitter's work task The fitter's work scope is very wide. It mainly includes marking, parts processing, assembly, equipment maintenance and innovative technology. (1) marking lines are used to mark parts before machining. (2) The manufacturing of parts that are not suitable for machining or can not be solved by mechanical methods, as well as all kinds of tools, fixtures, measuring tools and special equipment, should be completed by locksmiths. (3) Assembly: Assemble the processed parts according to the technical accuracy requirements of machinery to make them into a complete machine. (4) Equipment maintenance The parts of mechanical equipment that are damaged, out of order or lose precision after long-term use shall be maintained and repaired by locksmiths.

(1) General assemblers (assemblers) are mainly engaged in assembly adjustment of machines or parts and locksmith processing of some parts. (2) The fitter is mainly engaged in the maintenance of various machines and equipment. (3) Mold fitter (tool fitter) is mainly engaged in the production of molds, tools, measuring tools and templates. 5. The locksmith's basic operating skills include scribing, chiseling, sawing, drilling, reaming, countersinking, reaming, tapping and tapping, straightening and bending, riveting, scraping, grinding, basic measuring skills and simple heat treatment. No matter what kind of fitter, we should first master the basic operating skills of fitter, and then further learn and master the skills of fitter in processing parts, assembling and repairing products and equipment according to different division of labor. 6. Fitter skills require strengthening basic skills practice, strict requirements, standardized operation, more practice and more thinking, hard work and innovation. Basic operating skills are the basis of product production and fitter's professional skills. So you must master them first, so that you can gradually become handy and use them freely in your future work. There are many basic operation items of locksmith, and the learning and mastering of various skills are interdependent.
