Experience in metalworking training

Part 1: Metalworking Internship Experience

From October 12th, our 07 food class 3 conducted a two-week metalworking internship in the metalworking internship workshop of Xingong Building. During the period, we came into contact with the four types of work such as pliers, car, welding and planing. Under the patient's patience and meticulous cooperation, we did not have a case of injury accidents, basically met the expected internship requirements and completed satisfactorily. A two-week internship.
Before the internship, I heard that my brother and sister said that the metalworking internship was very hard, but I was a little excited when I first entered the workshop. When the teacher explained the precautions to us, it highlighted the safety issue and listed a bloody safety accident. At this time, we thoroughly realized the importance of safety.
Then we were arranged for different types of work. On the first day, I was assigned to work as a trainer. Under the teacher's brief introduction, we understand the function and use of the various components of the lathe, and then we have to use a cylindrical shape of the lathe. After the teacher demonstrated how to drive the workpiece, we began to familiarize ourselves with the operation of the turntables and handles of the lathe, and then went to the group of three people to operate the lathe. But when we were the first workpiece in the car, it was not so smooth, repeated car grinding, and repeated calculation of dimensions. After a long half of the day, the first piece of work finally came out. Although the size was not so precise, the sense of accomplishment came to life. After two days of practice and summing up the experience, we basically mastered the operation of the lathe and completed the teacher's assessment of us.
On the third day, I have to learn about welders and planers. I am no stranger to the welder. I have seen the flashing electric sparks on the construction site countless times. I know that it is welding, but the first automatic welding is the first time. The teacher gave us a detailed description of the welding related operations and some precautions. The odor and glare of the welding are harmful to the human body. We must know how to protect ourselves during operation, and require a cover and gloves. From the teacher's explanation, I learned that the angle of the welding rod is generally between seventy and eighty, and the speed of the moving rod is required to be uniform. At the beginning, some female students had a sense of fear about this thing, but after practicing a few times, they naturally got used to it. I thought it was easy to operate, but the fact was not like that. It was much harder than I thought. I welded the steel pipe, there was a hole, and it was not connected here. It turned out that this is really easy to learn. During the study of the welder, the arc is sometimes irritated by the welding, but each of us insisted on the basic knowledge of welding, but in order to be the standard of professional workers, we need to practice repeatedly, practice makes perfect . Although welding is very tired and dangerous, we have soldered it and experienced it. We will have the opportunity to practice it in the future. Then, to start learning the planer, after learning the lathe, it is much easier to operate the planer, and successfully completed the workpiece required by the teacher.
Soon after the second week of the metalworking internship, it was the hardest job. The teacher told us that the fitter is a complete manual to make a variety of parts, is the best ability to exercise a person. Then we will introduce the correct usage of vise, hand saw and various files, and we will use these tools to make a cylinder into a hammer. First of all, we have to saw a plane out, this is how I realized the hard work of the fitter, keep an action, repeatedly saw back and forth, hundreds of back and forth, hands and waist are sour. But I understand that this test is our perseverance and endurance, so we only insist on a little bit of sawing. After the saw is finished, it is necessary to use a sickle to flatten it a little bit. It is time-consuming to use rough and fine. After two days of hard work, my workpiece finally had a hammer shape, and then punched, and the edge of the hole was flattened with a round. When I took the work to the teacher for review, I thought that my work had been successful, but the teacher looked at it and pointed out a series of defects and deficiencies in my work. At this time, I discovered that the fitter's rigor and skill, precise size, beautiful form, and correct operation are indispensable.
The short two-week metalworking internship was over, looking at the souvenirs in my hands, which was exchanged for countless sweats and wisdom. Recalling the good times of these two weeks, there is a feeling of enrichment and harvest in my heart.
Through this study, although we have not learned a lot, as the teacher said, three years of training, but we are familiar with and master certain engineering basic knowledge and operational skills, cultivate, improve and strengthen our engineering practice, Innovative awareness and innovative ability. Learning what the book does not have, only combining theory with practice, this is the true meaning of technology. I believe that this internship will accumulate experience for us to enter the social employment in the future, and it is another valuable asset in my university life.

Part 2: Experience in the experience of college students in metalworking

Metalworking internship is a practical basic course, which has great significance for cultivating our hands-on ability. It also allows us to understand the traditional mechanical manufacturing process and modern mechanical manufacturing technology. As a student of non-mechanical major, but car and machinery are actually all the way, it is important to learn theoretical knowledge, but the ability to do it is also very important. Our college students usually have less opportunities to do it themselves, and the ability to do it is poor. The demand for comprehensive talent in society. The metalworking internship course brings us practical opportunities for physical and engineering students. Let us walk out of the classroom and do it ourselves in a variety of workpieces and machine workshops. These help for us is huge. .
During the internship, I participated in the lathe, welding, and fitter. I learned a lot of valuable things from it. It taught me what I couldn't learn in books and enhanced my hands-on ability.
The first metalworking internship was very fresh for us. After completing the English class in the first two sessions in the morning, we rushed to the internship base and went to the metalworking workshop. The teacher explained the meaning of the metalworking internship and the curriculum. And security issues during the internship.
The first type of work to be contacted is a lathe. The lathe is using the rotation of the workpiece and the movement of the tool to machine the surface of various revolving bodies on the lathe. Next, the teacher asks us to make the outer circle of the automatic cutter. The diameter of each car is 20 mm, then the cutter can only advance. 10mm, and be proficient in the operation sequence: first adjust the tray to the workpiece zero, retract the knife to advance 10mm, drive, when the knife advances to 3/4, change the manual to the precise position, retract the knife . After several training sessions, we are already familiar with this operation. Although it seems to be a very simple thing, I did know that the small gap caused the whole part to be good or bad. 1mm usually feels very small, it doesn't matter, but the parts are processed on the lathe, I know how big the mistake is 1mm instead of error.
After the turner was a welder, and I saw the flashing electric sparks on the construction site countless times. I know that it is welding. I thought it was easy to operate, but the fact is not like that. It is much harder than I imagined. The odor generated by welding and the glare of the light are harmful to the human body. We took the protective cover and started the operation of my welder. From the teacher, I learned that the angle of the welding rod is generally between 70 and 80. The requirement is of course constant speed. However, in actual operation, we tend to be slow and slow, and it is difficult to maintain a constant speed. Therefore, the result of the welding is very smooth, and in some places, the residence time is short, of course, there is no welding, and there is a crack. In places with long stays, there are often problems of being penetrated and there are loopholes; during the practice, the electrode is often stuck to the iron plate, and the red electrode is looked at, and the heart is in a hurry, but later In the repeated experience, I still mastered some tricks. This time, I realized that I don’t want to look at one thing too simple. I only have done it myself. I have experienced it before I know it.
To the last item, it is also the hardest one - the fitter. Looking at the vise on the workbench and the various tools placed on the left and right: The hand saw and the various sickles know that we have to use our own sweat and hands to make the hammer. Next, we started to clamp a cylinder on the vise, and started the work of the hammer according to the teacher's dash. It didn't make much progress when I saw the iron block. Later, under the guidance of the teacher, I quickly got the kind. The feeling of "rope sawing off". Next, I used the scorpion to flatten the iron surface. During this period, I saw the hammer become smooth and crystal clear. Although the arm and the arm were very painful during this period, I saw that my hammer was changing every day. Not happy. The last day, the hammer finally came out. I watched it think about the process of the week. It seems that I really grew up a lot. This is a craft that I did by myself. Although some of them are substandard, I really realized the importance of doing it. Sex.

Part 3: Experience in Metalworking Training

The five-week metalworking internship was over. Although it was very tired during the internship, we were very happy because we learned a lot of useful things while exercising our hands-on ability. Although the internship period is only a short five weeks, it is only a small part of our university life, but it is a very important part. For us, it is very difficult to forget. After all, it is a real experience society. Experience life.
Through this metalworking internship, I learned the basic knowledge and basic operation methods of fitters, turners, milling, grinding and CNC cars, milling, sparking machines, wire cutting machines, etc. I mainly learned the following aspects: the operation of fitters, turners, millers, millers, etc.
The first one: hard fitter
In the fitter's internship, we know that the main contents of the fitter are scraping, drilling, sawing, boring, assembling, scribing; understanding the construction, classification, selection, boring posture, boring method and quality of the boring tool. Detection. Our training project is to make a little girl, it is easier said than done. Our task is to manually drop a 115cm long round bar of 30 into a 20×20 long 112cm small steamed bun. Inadvertently, the entire work will be scrapped. First of all, it is necessary to hold the boring tool correctly. Keeping the straight motion of the boring tool when cutting the plane is the key to boring. The boring force has two kinds of horizontal thrust and vertical pressure. When the file advances, the front hand pressure gradually decreases, and the hand pressure is large and then small. When the file is pushed to the middle position, the pressure of the two hands is the same. When the file is continuously pushed, the pressure of the front hand gradually decreases and the pressure increases. No pressure is applied when the file is returned. This way we are more difficult to cut. At the same time, I also know that the safety technology of the fitter is: 1. The clamp table should be placed in a place where work and light are suitable; the drill press and the grinding wheel should generally be placed at the edge of the site to ensure safety. 2, the use of machine tools, tools, should be checked frequently, found that damage should not be used, need to be repaired and reused. 3. When the vise clamps the tool, it is not allowed to use a hammer to hammer the handle or the steel pipe to apply the clamping force.
Then there are scraping, grinding, drilling, reaming, and the like. Although not very standard, it is the crystallization of our sweat and the result of our struggle for a few days.
The internship of the fitter is very boring. It may be an afternoon, but it is a reversal of an action, but also a force, but also to do it, that is, holding the sickle on the workpiece back and forth, At night, the whole person’s hands are sore and sore, and the legs are standing up with some rigidity. However, when they are tired, they can see the teacher guiding them and demonstrate them personally. Like us, I see this and give me every time. Take power. A few days later, looking at my own processing results, what we want to say most is to thank the teachers who have guided us.
The second item: easy turner, milling
Turning and milling are not done by CNC, which requires high manual operation. First of all, the teacher told us to listen to the lathe and familiarize with the various components of the lathe. The lathe is mainly composed of gearbox, headstock, hanging wheel box, feed box, slide box, knife holder, tailstock, bed, screw, light. The bar and the joystick are composed. Milling machines mainly consist of a spindle box, a spindle, a column, an electrical cabinet, a work table, a coolant tank, and a bed. The lathe and milling machine are operated by various handles. The teacher explained the function of each handle to us, and then let us familiar with the practice of machining parts. The teacher first demonstrated the operation method and processed a part, then let us start processing. A very important aspect of lathe machining is to choose the right knife. At the beginning we have to drive a bearing-like part. This is a test for those of us who have never used a lathe.
Constantly turning the horizontal and vertical control handles, careful processing, and doing a whole afternoon, when I thought I was about the same time, I was prepared to take the last knife, but I was too hasty to make the diameter of the arc small! I am distressed, miserable! The most uncomfortable thing was that I stood up all day and my calves hurt. But the joy of success when I handed the good parts of the car to the teacher made me forget the calf that stood so painful. The joy of this success is only through personal experience. You can feel it by participating in training.
As a college student, we have experienced more than ten years of theoretical study. We have been told more than once that there is a gap between theoretical knowledge and practice. However, we have not taken this sentence seriously and have no chance to verify the actual gap between this sentence. how many. The metalworking internship gave us an opportunity to actually master the knowledge, leaving the rigorous environment of the classroom, we felt the atmosphere in the workshop. The eager eyes of the students and the conscientious and patient operation of the instructors constitute the common scenery in the workshop. We have felt the importance of hands-on ability in the classroom for a long time. We can't complete the actual work only by thinking and figuring in the brain. Only when we have a scientific knowledge system, we are proficient in practical ability, including mechanical operation and experience. Continuous accumulation can make knowledge flexible and effective in practical work. Metalworking internship is an effective way to cultivate students' practical ability. Here is another learning class. Through our hands, we supplement and question the theoretical knowledge we have mastered. This is the opposite of traditional classroom education. These two learning methods complement each other and complement each other, can fill in the gaps and make up for some blind spots. Through the metalworking internship, the overall feeling of actual production methods is still relatively backward. The advanced equipment introduced in the book is still not practical. The equipment in the internship is often characterized by high labor intensity and low technological content, but there are still some basic knowledge. Can be applied in practice.
The third item: grinding operation and CNC car, milling, spark machine, wire cutting machine, etc.
When our training was coming to an end, the teacher took me to the grinding workshop to explain the operation of the grinding machine. After we listened carefully, I started to move my own hands, and I used my own machine tool to grind my front fitter training. The gimmick made, with the teacher's careful knowledge, we used our lathe to process one side again, making our first work more perfect. After completing the grinding task, the teacher took us to the CNC training room to explain the principle and operation of some CNC equipment, which enabled us to lay a solid foundation for learning theoretical knowledge in the future.
All in all, although in the five weeks of training, what we have learned is only a fur for the technicians, but there is a process in everything. What we have learned is the basic basics, and the technicians come from simple to complex "evolution". The most gratifying thing is that no classmates are injured in these kinds of internships with different degrees of danger. On the contrary, there will be some sweet smiles from time to time in the internship. This is inseparable from the seriousness and care of the students. The metalworking internship made me feel the bitterness and joy of being a worker, and tested the knowledge I had learned. The metalworking internship makes me deeply understand the meaning of life - there is no difficulty in the world, as long as the kung fu is deep, the iron smashed into a needle!

Part 4: Experience in Metalworking Internship

Time flies so fast, and the internship time of three weeks in a blink of an eye is over. During this time, I learned a lot of things that I couldn't learn at school, and I realized that I have a lot of deficiencies, and I feel that my income is not good.
“Metalworking Internship” is a practical subject-based course. It is also an important compulsory course for engineering students to carry out engineering training, cultivating engineering awareness, learning process knowledge, and improving overall quality. However, as a student of engineering, we have not received serious formal engineering training before. As far as I am concerned, it is very likely that due to long-term neglect, the engineering consciousness is weak, and there is no enough attention to the essence of this engineering thinking. At the same time, in actual operation, it is far from the requirements of work. In fact, as a freshman, it is unscientific to directly contact esoteric professional knowledge before taking a professional course. To this end, the school led us to carry out this internship, let us get a sense of mechanical profession from practice. Recognize and lay a solid foundation for the study of professional courses in the future. Practice is a very important part of university life, a source of constant knowledge and development, a touchstone for testing truth, and an effective way for college students to exercise and grow. It is even more important than classroom. A person's knowledge and ability can only be effective in practice, in order to be enriched, improved and developed. For college students to grow up, they must be diligent in practice, combine the theoretical knowledge and practice they have learned, continue to learn in practice, continue to summarize, gradually improve, innovate, and improve their knowledge, ability, wisdom, etc. in practice. The comprehensive quality and ability of the factors are combined to lay a good foundation for the success of their own career.
This is the first lesson of my internship experience: the first day of the car work, my heart is full of expectations, after all, is the first internship.
There are a lot of things to be remembered by the lathe, but since I had a relatively thorough psychological preparation and theoretical preparation, I would not be too busy. But when you really get it, all kinds of problems will follow. First of all, the first time, the fear of the feet, many processes know that they are doing this, but they are not sure, perhaps because of the first contact with the lathe, it is still very nervous. There is always a problem with the classmates, no matter how patiently the teacher guides.
One morning, I haven't processed a simple hammer handle yet, but I have no big problems at all, and it is a great fortune. In the afternoon, I will continue my unfinished work in the morning. After a morning of adaptation, the hammer handle was quickly completed and it felt pretty good. So my heart was a little fluttering, and it was because of this that I made a mistake when I was doing the second hammer. I used the wrong angle of the knife when cutting the cone. Fortunately, under the guidance of the teacher, remedial measures were taken and the task was finally completed. At the time of the thread, our team always worried about the problem, which was done under the patient guidance of the teacher.
Lesson 2: The fitter has no passion for the first day and feels very tired. But still full of expectations.
The work we have to do is to punch the hammer with a variety of borings, set the spiral, and assemble.
The whole process of this type of work is physical work. Everyone feels very simple when the teacher explains it, but the actual process is quite different. I remember that some brothers and sisters described it as a "turner, even the face was oiled, knife Spoiled splashes; fitter, full of cockroaches and bubbles on the hands, sweat dripping." Although a bit exaggerated, but it really reflects the hard work of the fitter.
The process is hard, but the results are gratifying. Despite a small holiday on May 1st, after two days of sweat, I finally got a hammer.
Lesson 3: Milling, planing, and grinding machines are a bit accustomed to metalworking internships.
There is a lot of content today, but the process is much easier. Mainly to see the demonstration, the masters are very skilled in the operation, really envious. I have a few hands to get started, and it feels good. The way to take the exam is good, draw lots, huh, huh.
Lesson 4: Casting
The most tiring lesson.
With sand molding, I suddenly found the feeling of childhood, but this is obviously not a child playing with sand, but a very careful thing, because the mud is very easy to deform, so be careful when doing it.
The last lesson: welding and pressure casting are a bit reluctant and a little excited. Faced with a brand new technology, I used to look at other people. I felt very simple. It was really difficult to find out when I started to work. Especially welding, I have practiced for a long time.
I still have a lot of experience during my internship. The first is self-learning - after work, no longer like studying in school, there are classes, homework, exams, but everything must be taken on its own initiative. As long as you want to learn, there are still many opportunities for learning. The masters never despise their own experience to guide us to work, let us take less detours; group companies, companies have a variety of training to improve themselves, we have to do It’s just what you need to know and what you are interested in. In the internship unit, I met a few very kind old employees. As long as they asked them technical questions, they will answer them one by one, which made me understand that there is a big gap between the theory and the actual situation. It also made me understand some problems that are not understood in the classroom. The second is a positive work attitude - in the work, you not only create benefits for the company, but also improve yourself, newcomers like me who have no work experience, but also need to learn more by doing more questions. In particular, our work does not have a clear scope of work as a formal employee. It is just a free observation. If the attitude is not active enough, there may be no things to do. Therefore, it is more necessary to actively strive for more things, so that we can accumulate more and improve. The third is the basic etiquette - you need to understand the basic etiquette when you step into the society, and this is often not taken seriously by the students. Whether it is dressing or waiting for people, it should be ceremonial, so as not to affect the normal work. This requires more learning, such as paying attention to other people's practices or consulting with experts. The fourth is to do things for people - as students face nothing more than classmates, teachers, parents, and work to face more complex relationships. Whether it is in contact with leaders, colleagues or customers, it must be handled properly, communicate more, and be empathetic in terms of each other, rather than just thinking about your own affairs.
I think that through this internship, I have recognized many of my shortcomings and shortcomings. The first is the lack of work experience. Because I lack experience, many problems can not distinguish between the primary and secondary, and some training or learning can not find the key points. With the internship work, I think I will gradually accumulate experience. The second is that the work attitude is still not positive enough. In the work, only the work of arrangement can be completed. When there is no work task, the work can not be actively requested. If there is no work, it will be lax and cannot be actively studied. This is mainly because laziness is at work, and I will try to overcome it in the future. Inert, when there is no work task, it is required to arrange work, and when it is not arranged, it is self-learning. The third is that we still need to pursue perfection when we work. We are not allowed to be sloppy at work. Strict and serious is always to be kept in mind. The fourth is that the ability to do things is too bad, watching the master do a very good job, always feel very simple, but I actually found it really very difficult to actually operate.
Solid professional knowledge is a solid foundation for improving the level of work. When studying professional knowledge in school, it may feel boring, but when you work, you will find out how important professional knowledge is. But I want to improve my work efficiency, work quality. This knowledge is only known to be far from being, but to be proficient. As a production technology, it is the authority of equipment in the automobile company. If there is no solid mechanical knowledge, how can you serve people in this respect? How can the problem of equipment be solved quickly and effectively?
to sum up:
The phrase "painful and happy" is used to describe a three-week metalworking internship. This internship has brought us more than just experience. It has also cultivated our hard-working spirit and rigorous and serious style. It doesn't matter if the workpiece is a few millimeters apart, and every error can cause huge losses.
"There is a glimpse of the end of the paper, and I’m going to practice it."
In just three weeks, it has passed, tired, bitter, and thought about it. The work is not so satisfactory, but the significance is very significant. After a minute of hard work, we get much more exercise than we pay.

Part 5: Experience in Metalworking Training

The four-week internship is over. As for the overall feeling, it can only be summed up in eight words. "Although it is hard, it is very fulfilling." During these three weeks, I have learned a lot of useful knowledge. I also deeply understand the hard work and greatness of the workers. The internship internship is one of the compulsory courses for our mechanical and electrical majors. Maybe we will not really engage in industrial production in the future. But the precious experience that I have left for three weeks is never forgotten, and will serve as a wealth I can use for my life.
At the beginning, I felt that the time was long. Three weeks, when can we get through this internship? However, in the twinkling of an eye, the last week has arrived. The last day is about to wave to us. I don’t know how, the last day I have been looking forward to, but when this day really comes, we suddenly have a strong hardship for the internship. The feelings, really do not want to be separated from you - the fitter internship, you let us get endless knowledge in happiness.
During the internship, I had a deep feeling. I am very grateful to the school for providing us with this internship opportunity. It is not easy for us to experience the engineering and engineering in advance. We have acquired the knowledge that we can’t get and can’t think of in the classroom. Maybe we won’t go in the future. This post, but the knowledge and feelings I have learned now are unforgettable. Although the dirty spots are tired, these do not matter. What is important is that we have gained and achieved results.
When I first started working, I bent over and sweated my head and sweated. From time to time, there were some red "patterns" on my hands. But looking back at the results of my work, I feel that I am more and more irritated by my own contribution. After being discovered by the teacher, after patiently explaining, I realized that my posture and position of processing were wrong. After adjustment, it is slowly entering the state. However, it is still full of loopholes, forgetting the control of dimensional tolerances for a while, and forgetting the coordination of flatness and verticality for a while. Every time something goes wrong, the teacher always comes quietly to the right to guide. Make such a mistake leave a deep impression in your heart and avoid similar mistakes in the future. This completes the first part. When I got the teacher to test it, a lot of mistakes were realized after the teacher analyzed it. But every analysis guide has left a deep impression on me. Completed the second, third... Every time there is progress, but every time there are still errors, but the mistakes are getting less and less. This shows that my fitter is moving towards a higher level step by step, which gives me another confidence.
It seems to be long around, but it is also very short. During the break, the teachers and students shared a big laugh and a serious face at work. Five hours a day quickly passed. I didn’t feel tired until I got off work, but my heart was full. Although it is only five hours a day, it makes me feel the atmosphere of work, and the working environment is a feeling I have never had before.
Every day, everyone has to learn new techniques and complete the process of making a finished product from nothing about each type of work in a five-hour internship. Under the patient's patience and meticulous cooperation, the teachers basically met the expected internship requirements and successfully completed the three-week training. During training, learn by fitter. We made our own crafts. The fitter is the most labor-intensive. A tool such as a file or a hacksaw is used to manually grind an iron block into the desired shape, and then through a step of punching and tapping, finally forming a workpiece. One afternoon, although many of my classmates had blisters on their hands, they were sore, but when they saw the finished products they made in the factory for the first time in their lives, everyone couldn't help but feel very fulfilled. The experience of this training is: First, in the process of understanding, familiarizing with and mastering certain engineering basic knowledge and operational skills, we have cultivated, improved and strengthened our engineering practice ability, innovation consciousness and innovation ability. Second, cultivate and exercise the labor perspective, quality and economic concepts, strengthen the observance of labor discipline, abide by safety and technical rules and the consciousness of caring for state property, and improve our overall comprehensive quality. Thirdly, during the whole training process, the teachers have strict requirements on our discipline. At the same time, we have strengthened the requirements for filling in the internship report, cleaning up the workbench, and observing the safety operation rules of each type of work, which has improved the comprehensive engineering quality of students. Good promotion. Fourth, the training teachers announced the scoring standards of our processed products to us, so that we have a clear understanding of the scores of our products, which has a certain effect on improving our quality awareness. For our training results of the fitter, we will carry out an inspection method one by one, so that we can take each job and every internship seriously.
I feel that every training is very meaningful to me. It is very real. They have added a wonderful stroke to my university life. Let me be closer to the life of skilled workers, let me grow more professional knowledge, let I recognize my strengths and weaknesses. When we are employed one year later, the employment unit will not tell us as much as we do with the teacher, and we need to observe and learn by ourselves. Without this ability, it will be difficult to meet the challenges of the future. With the rapid development of science and the wide application of new technologies, there will be many areas that we have never touched before. Only dare to try to make breakthroughs and innovations. Like a fitter, it seems to be a simple slap and a grind. We need to carefully observe and repeat the practice. If we fail, we will start all over again and cultivate a sense of frustration and so on. The three-week training brought us not only the operational skills we have come into contact with, but also the ability to exercise through several types of work. More needs us all after the internship. According to my own situation, I will feel, rethink, be self-satisfied, and gain something, so that this training has achieved his true purpose.
All in all, although in the internship for ten days, what we have learned for the technicians is only the fur of the fur, but there is a process in everything. What we have learned is the basic basics, and the technicians come from simple to complex "evolution".
Soon after the internship is over, everyone is happy at the end, because everyone has learned the real thing, whether it is very refined, whether it is really mastered, at least let us know what is the worker doing, It will also help in the future.
