Three 2000-word summary of milling internship

Part 1

1. Purpose of Internship

Finally it’s time for the internship. I learned about the internship from my senior brother a long time ago. At that time, I can It is said that they are eagerly looking forward to the arrival of this day, because everyone can no longer be satisfied with classroom teaching, even though they learned from classmates and friends that internship is not as happy as imagined.

Looking back suddenly, the one-week milling internship was over in the blink of an eye. Although it was very tiring and hard during the internship, I felt very happy! Because we learned the necessary knowledge as a miller and also exercised our hands-on ability. And it also made me more deeply understand the great poet Li Bai’s famous saying: As long as you work hard, an iron pestle can be ground into a needle. On the first day of our internship, we read the relevant knowledge about the milling internship and my milling internship process. Notes on the disc. Seeing the spinning machine and the flying iron made me both worried and excited. What I am worried about is that the rumbling sound of the flying machine will make people's hearts tremble and the bright red iron flowers splashing everywhere and the dazzling light will be dazzling; what I am excited about is that the milling internship that I have been waiting for for nearly a year is about to begin. This is the first time for us as students to enter a factory as respectable workers, and it is also the first time to go to an internship base where every engineering student can try his skills.

In fact, for us engineering students, this is an excellent opportunity to combine theory and practice, and will comprehensively test our knowledge level. Milling internship is a compulsory technical basic course with strong practicality for students majoring in mechanical engineering. During the milling internship process, students organically combine basic process knowledge, basic process methods and basic process practices related to mechanical manufacturing through independent practical operations to train the comprehensive ability of engineering practice and cultivate ideological, moral and quality. Exercise.

Milling internship is an effective way to cultivate students’ practical ability. It is also a required course for our college students, engineering college students, and college students. It is very important and especially the milling internship. It is also an opportunity for us to actually master knowledge. Without the rigorous environment of the classroom, we will feel the atmosphere of the workshop. . At the same time, we also feel more about the mood of being a worker, which makes us more aware of the responsibilities we shoulder.

Through the teacher’s explanation. I finally understood what a miller is. At the same time, I also understood why some people say that "being a miller is the most tiring!" Millers mainly operate manually and use various tools to complete the processing, assembly and repair of parts. Compared with mechanical processing, the labor intensity is high and the production efficiency is low, but it can complete the work that is inconvenient or difficult to complete by mechanical processing. At the same time, the equipment is simple, so it is still an indispensable and important type of work in machinery manufacturing and repair work. Commonly used equipment for millers include milling tables, bench mills, grinding wheels, etc.

2. Specific content

In this internship, I mainly work as a miller. The so-called miller is a skilled worker who uses a milling machine (equipment for processing parts) to process parts according to the design part drawings. Divided into junior workers and senior workers. Parts processing accuracy requirements are high.

Operation requirements for millers

1. The milling table should be placed in a place that is convenient for work and with suitable light; the drilling machine and grinding wheel should generally be placed on the edge of the site to ensure safety.

2. When using machine tools and tools (such as drill presses, grinding wheels, hand drills, etc.), check them frequently. If they are found to be damaged, they must not be used. They need to be repaired before use.

3. When clamping the milling tool, do not use a hammer to hit the handle or steel pipe to apply clamping force.

4. When using power tools, insulation protection and safety grounding measures must be taken. Wear protective glasses when using the grinding wheel. A protective net is required when operating on the milling table.

5. Blanks and processed parts should be placed in the specified position, arranged neatly and stably, ensuring safety, easy to pick and place, and avoiding damage to the processed surface.

6. When drilling, reaming, reaming, countersinking, tapping, and threading, the workpiece must be firmly clamped. When processing through holes, the workpiece must be cushioned or the tool should be aligned with the workbench. groove.

7. When using the drill press, do not wear gloves and do not operate with cotton yarn. When replacing cutting tools such as drill bits, special tools must be used. Do not hit the drill chuck with a hammer.

Purpose of milling internship:

Understand the process characteristics and processing scope of milling.

2. Understand the composition, movement and uses of commonly used milling machines, and understand the general structure and uses of commonly used cutting tools and accessories for milling machines.

3. Be familiar with the processing methods and measurement methods of milling, and understand the processing of simple indexing using an indexing head.

4. Correctly secure the workpiece and tool on the milling machine and complete the milling of flat surfaces, grooves, etc.

The above is the basic knowledge of milling. What I always keep in mind during the internship is also the consolidation of book knowledge.

Next, let’s talk about my internship experience.

In the first theoretical class, the teacher first emphasized the matters that should be paid attention to during the operation of the milling machine. Then the teacher introduced the concept, characteristics, processing scope and related physical quantities of milling in detail, and led us to visit and explain Components and Contacts of Horizontal and Vertical Milling Machines After explaining the above content, the teacher led us to the milling machine and introduced in detail how to clamp the workpiece and related operations, and how to perform plane milling.

2. It’s time for practice. We work in groups of 5 and mill planes on the milling machine. From the simplest start-up and shutdown, to clamping the workpiece, to tool setting, cutting, and finally completing the processing of the workpiece, our team has achieved gratifying results.

3. Since we first milled planes on a vertical milling machine, our group exchanged machines with other groups and we practiced on a horizontal milling machine. Horizontal milling machines can mill planes very quickly. Unfortunately, the oil pumps of the school's two horizontal milling machines are broken, and the automatic movement of the worktable in the three directions of horizontal, vertical and vertical feed is also broken. Fortunately, we There are enough people. In the end, with our concerted efforts, each qualified workpiece was successfully "born".

4. On the second day of the internship, the difficulty increased. In the theoretical class, the teacher explained the commonly used tools on milling machines, their characteristics and how to use them. After explaining how to mill grooves, we started our "work". The processing of grooves is much more difficult than that of flat surfaces. In order to ensure the accuracy of the workpiece, we are careful in every operation. As a result, some workpieces are not up to standard, maybe because of the tool!

5. The connection between the plane and the groove has come to an end, and we have also started our small test. We completed the processing of the workpiece within the time specified by the teacher. After a lot of hard work, we finally passed the test successfully.

6. The third day of internship was even more difficult. We were supposed to practice milling step surfaces as well as milling equally divided parts, but time was limited, so we only practiced milling steps, and by the way, divided parts , we only use the universal dividing head for equal division and do not process it on the milling machine.

3. Summary of experience

Through internship, I have a deep understanding of the characteristics and processing scope of milling, as well as the composition, working principle and use of milling machines; I have the ability to complete the work independently Ability to measure workpieces, process planes and grooves, and replace and install tools; the purpose of the internship has been achieved.

2. The operation of the milling machine is simple and easy to learn, but you must not relax during the operation to prevent accidents.

3. We know that the main contents of milling are scribing, chiseling, sawing, filing, scraping, grinding, drilling, reaming, reaming, countersinking, tapping, and threading , assembly, and repair, etc. Understand the structure, classification, selection, filing posture, filing method and quality inspection of files.

4. Understand the knowledge of mechanical manufacturing processes and the application of new processes, new technologies and new equipment in mechanical manufacturing, cultivate, improve and strengthen our engineering practice ability, innovation awareness and innovation ability.

5. The milling internship has cultivated and exercised us, improved our overall comprehensive quality, and enabled us not only to have a deeper understanding of the importance of the milling internship, but also to improve our practical ability. It enables us to better combine theory with practice and consolidate the knowledge we have learned.

6. We also learned from the teacher’s dedication and rigorous spirit. The teachers impatiently helped us find errors in the program over and over again. Some programs are particularly long, but the teacher doesn't care about these. As long as there is a slight flaw, he must find it out and do his best to make the students' works more perfect. Some teachers will demonstrate how to operate it again and again until the students really understand it.

Part 3

Time flies so fast. The two-week metalworking internship ended with the end of the last written test yesterday afternoon. During this time, I learned a lot, saw many novel techniques, and learned about the working environment of technicians. I think this two-week internship will bring me a lot of valuable experience in my future work.

On the first day of the internship, I came to the workshop stupidly. I didn’t expect that what we had to do was to learn a software-Solidworks, but it was really fun. We followed the tutorial step by step. They all studied very seriously! After learning the basic operations, I used my imagination to draw a three-dimensional figure and tried to simulate it with tools. In the end, it failed! Haha, it was then that I discovered that, Mastering a software is really not as easy as imagined, and it is even more difficult to use it skillfully to make the workpieces we need. We really need to study hard in the future!

Next, the most thrilling thing Here comes the scene - safety education. Looking at the horrific scenes, dangers are everywhere. I unconsciously imagined that I would experience this internship personally in the next two weeks. Will I have any safety problems of this kind? The more I thought about it, the more uneasy and uneasy I became. After watching the film, I secretly promised: Be careful!!

The next day, I felt that the real internship had begun. Milling, a job I have never heard of, is exciting. As soon as I entered the workshop, before the teacher came, I felt uncomfortable - the smell of engine oil was strong. To be honest, I have been very sensitive to, and even disgusted with, gasoline, diesel, and engine oil throughout my life. Today was really a test! After the teacher’s explanation, I realized that in fact, as long as we operate according to safety regulations, the risk factor is not As high as we imagined. These words gave me reassurance. Under the uncle's detailed explanation, we understood the structure, specifications, operation methods and other relevant information of the milling machine. After that, a beautiful lady taught us how to use a milling machine to mill workpieces. Haha, we listened very attentively! After understanding the operation, we excitedly came to the milling machine and started our first project - cutting a cylindrical iron block with a diameter of 25mm into a square cylinder of 17mmx16mm.

My problem is here again. The entire milling machine is full of oil, and the cutting process must be lubricated. Oops, I am most afraid of coming into contact with these greasy things in my life, alas! However, an internship is an internship, and I was mentally prepared for it, so I bravely took action. Cutting millimeter by millimeter made me feel how long it took. Moreover, the whole process required attention to many details. One mistake would cause danger, so I did not dare to take it lightly. The two of us worked together to sharpen a piece of iron, which was easier said than done. Fortunately, with our cooperation, we finally completed the production of the first workpiece in our lives. It’s not over yet, here comes the thinking questions. After the actual operation, our understanding of the problem has been greatly deepened. We have unique feelings and thoughts when doing the questions, and feel that the arrangement is good! At this time, our team spirit also came into play, and soon , just like that, we completed the day's work.

In the days that followed, my schedule was almost the same.

We have successively done eight types of work, including Counting Lathe 928, Counting Milling 990, Chemical Processing, Injection Molding and Extrusion, Grinding Machine Gears, Electric Discharge Machining, Counting Lathe 980, and Wire Cutting. In addition to feeling fresh, there is one more job than the previous two days. ——Tired! Really, I was so excited at first that I completely forgot about being tired, but then, I completely felt the tiredness and suffering of the workers.

After two weeks, the metalworking internship ended, but it gave me a lot of feelings and experiences:

1) Through the internship, I learned about the production methods and processes of the modern machinery manufacturing industry. process, as well as the main forming methods and main mechanical processing methods of engineering materials, as well as the working principles and typical structures of the main equipment used, as well as safe operation techniques.

2) After many hands-on operations, I have initially mastered the independent operation ability of basic machines and can apply it in actual production. Moreover, hands-on operations have cultivated, improved and strengthened my engineering practice ability, innovation awareness and innovation ability.

3) The internship cultivated and exercised labor concepts, quality and economic concepts, strengthened the consciousness of observing labor disciplines, observing safety technical rules and protecting national property, and improved our overall comprehensive quality.

4) During the entire internship process, we have very strict disciplinary requirements. We have formulated a student internship schedule, and at the same time strengthened requirements for filling in internship reports, cleaning up machine tool sites, and complying with safe operating procedures for various types of work. , which has played a better role in promoting the cultivation of students' comprehensive engineering quality.

Generally speaking, I would like to thank the school for providing us with this internship opportunity, which allowed us to experience the difficulty of learning science and engineering in advance, and gained knowledge that we could not even imagine in the classroom. Maybe we will not be able to study in the future. I will take up this position, but the knowledge and feelings I have learned now will be unforgettable for a lifetime. Although it is a bit dirty and tiring, it doesn’t matter. What is important is that we have gained something and achieved results. When we are employed two years later, the employment unit will not tell us the work to be done in detail like a teacher. It is more necessary for us to observe and learn by ourselves.

Without this ability, it will be difficult to meet future challenges. With the rapid development of science and the widespread application of new technologies, there will be many areas that we have never touched before. Only by daring to try can we make breakthroughs and innovate. In addition, careful observation, repeated practice, starting all over again if you fail, etc. are all things I deeply felt during my metalworking internship. I feel that there is too much to say. The metalworking internship in just two weeks has brought us not only the operational skills we have come into contact with, but also the abilities that we are required to exercise through several types of work. , and more importantly, each of us needs to understand and reflect according to our own situation after the internship, work diligently to encourage ourselves, and gain something, so that this internship can achieve its true purpose.

In the days to come, I will work harder and work harder for the future!
