The one-week lathe work practice soon ended. Looking back on the knowledge and skills I have learned in the past week, I have a deep understanding.

First of all, theoretical knowledge and safety education are essential. Before turning the lathe to cut parts, the teacher spent a whole day teaching us theoretical knowledge. Although the first day was boring, it was just one of the most important materials. For example, when clamping the tool, the vertical distance between the blade and the bottom of the tool holder is 143.5mm, which reduces the number of tool alignment with the center of the part. When loading the tool, the gasket is directly measured with a ruler to be 143.5mm, which is basically equal to the center of the part, saving the time for tool alignment. When clamping the workpiece, it must be tightened with a booster bar to avoid accidents caused by parts flying out and the correct use of tools. Practicing rocking lathe is also an examination that every student must pass before practicing lathe every time. Only by skillfully rocking the big and middle drag plates can we make necessary preparations for turning parts to avoid collision between tools and parts. Because the lathe we practiced this time is different from the lathe we practiced on the job, there are differences in automatic feeding, and there are also differences in the adjustment of speed. After understanding some theoretical knowledge of lathe, the next day, we began to formally process parts.

when turning the first part, I still feel very nervous, and I pay attention to the wing at every step to avoid making mistakes. One square of the big drag board represents 1mm, and the middle drag board and the small drag board are .2 mm.. When turning the end face, stop the automatic feed and change it to manual feed when it is about 2mm away from the center, so as to prevent the cutter head from being damaged. When turning the excircle, the automatic feed should be stopped at a distance of 2mm from the size and changed to manual feed to prevent turning over and parts from being damaged. The first and second parts are turned by step shafts, which mainly let us master the control of excircle and the use and reading of micrometer. When measuring parts, vernier caliper and micrometer must be used together, and micrometer should be used for measurement within 1mm from the specified size, so that the size of the excircle can be effectively controlled. When there is a fine turning again, you must first try to cut and measure it to see if the size is within the range, so that the accuracy of the machined parts is relatively high.

the third part is machined with taper, and it is necessary to turn the necessary dial. When turning, first shake the large drag plate to the specified scale, then align the tool with the middle drag plate, then the small drag plate exits, and the large drag plate does not move. Finally, after adjusting the scale, manually feed it with the small drag plate to turn out the taper. First of all, you need to try to cut it, measure it with a universal square, and continue turning the tool under the condition of ensuring the correct angle. If there is a gap at the small end, it means that the angle is increased, otherwise it is small, so it is necessary to readjust the degree and try again. Before machining the taper, the parts must not be taken off the chuck, otherwise the turned taper deviates from the concentric axis of the circle, resulting in a curved line of taper.

The last day of processing is some basic operations of boring. First of all, be sure to drill holes. When using the drill, be sure to add cooling liquid. The drill should enter the parts and drill through slowly to prevent the drill from shaking and drilling out holes that are too big than the diameter of the drill. When boring, the main deflection angle of boring tool is 91 ~ 93. When turning, it is roughly the same as the excircle, but in the opposite direction. When measuring the size, you need to use the inner diameter dial gauge to measure.

On the whole, the first week's internship went smoothly without much difficulty. After all, it was because of the previous internship, and the turned parts were also practiced before, mainly because of the lack of length control of the parts. I look forward to continuing my efforts next week! Experience of lathe work practice model essay 2

2xx year x month x day is a memorable day for me, because it is the last lesson of my lathe work practice class.

I remember the first time I went to the Optoelectronic Building, I was excited and full of curiosity. I looked into the training room from the window: the machine tools were neatly arranged, and the smell that we students of Optoelectronic Department were familiar with floated out of the door-the smell of engine oil. The first two days I just went there were a preliminary understanding and understanding of the structure and operation of the lathe. After that, I carried out seven practical operations, including the processing of step shaft, door shaft, cone, die rack, hinge bar and jack, from which I also learned and used micrometer, vernier caliper, turning tool, center, drill bit and wrench.

in the process of practical training, I not only learned a lot of knowledge about processing technology, but also learned knowledge that was not in the textbook. In the process of training, I encountered many problems and made many mistakes. Through training, I learned to consult modestly, observe carefully and practice boldly. Any ability is accumulated in practice, and there will be a process from never attending meetings to being proficient. People often say that "life is the best teacher", which means that only by constantly honing in life practice can we improve our ability to think and solve problems independently. At the same time, it also cultivated its own excellent style of study, noble life, unity and cooperation spirit; Learned a diligent and realistic learning attitude.

Diligence means to work hard and not be afraid of difficulties. Han Yu, a thinker in the Tang Dynasty, famously said: industry is good at diligence, but barren at play; What is done is thought, but it is destroyed. Excellent studies are the crystallization of hard work and sweat, and achievements can only be achieved through hard study and hard work. Marx said: "There is no royal road to science, and only those who do not fear the fatiguing climb along steep mountain roads can hope to reach the pinnacle of glory."

Being realistic means being down-to-earth, seeking truth and being pragmatic, being modest and prudent, being arrogant and impetuous, mastering knowledge, being strict with norms, being rigorous and meticulous, and striving for perfection. One person's strength is limited, and the strength of unity and cooperation is infinite. Through the processing of various projects, I understand that although a grain of sand is small, countless grains can converge into an infinite desert; Although the water drops are small, you merge into a vast ocean; One of your ideas, one of his ideas and one of his methods are exchanged with each other, and there are two ideas and methods. The competition in today's society is becoming increasingly fierce, and we should learn to cooperate with others now.

Of course, in the process of practical training, we have also gained happiness, happiness with classmates and happiness with teachers. Because whenever I or myself and my classmates finish a project, I feel more or less gratified and happy, and it is also a kind of happiness to communicate with teachers at rest. Although the four-week training is not a long time, it is of great help to my future study. This is only the starting point, and the end point is still a certain distance from us, so we still need to continue to work hard to take the future road. And we should seize every opportunity, and if we miss it, we will never get it back. Model essay 3

With the cooperation of campus leaders and colleagues, we successfully completed the lathe training this semester. Looking back on this training, we have achieved good results in the following aspects:

First, there are no safety accidents

Unlike ordinary classroom teaching, students in the workshop deal with workpieces, tools, metal fragments, etc. that fly out at high speed at any time due to improper operation on the high-speed rotating machine-level lathe, as well as grinding wheels that rotate at high speed and burst at any time due to careless operation. These may pose a great threat to students' personal and even life safety, which is also the biggest hidden danger in the lathe training class. As a training instructor, we should never forget the idea of safety first in the teaching process. We should emphasize safety in the concentration before each class, and students can always strictly demand standardized operation in the operation process. We should emphasize the existing safety hazards in the summary before class. Teachers take pains to talk about safety and emphasize safety, and constantly cultivate students' awareness of safe operation. Over time, students gradually develop the awareness of safe operation, standardized operation and polite operation, thus ensuring that no safety accidents occur during the whole training process.

Second, strengthen management, reduce consumption, and reduce training cost

The training cost of lathe workers is high, and raw materials and measuring tools are consumed in the training process. However, in order to save costs and reduce consumption, the management of materials, tools and measuring tools has been strengthened, and the access of various materials has been strictly controlled. For the materials required by each student in the training process, students have personally cut the materials, and teachers have carried out < And each raw material is marked, which is convenient for students to manage their own materials. Finally, at the end of the training, each student will register and score the parts of his own raw material mechanic.

in the process of training, the existing students should report the damage of tools and equipment caused by various mistakes, and then the monitor should report it to the teacher, and then * * * analyze the cause of the accident, and compensate for the heavy losses caused by the failure to operate according to the standard or personal behavior as appropriate. Thus, students are stimulated to seriously standardize the operation according to the teacher's requirements in the operation process, which greatly reduces the occurrence of various accidents, reduces the damage of various materials, tools, measuring tools and equipment, reduces the consumption in training, and greatly reduces the training cost.

Third, strengthen the training assessment to urge students to operate carefully

According to the requirements of campus teaching, strengthen the assessment of students' usual performance. In this training process, the students' training performance is refined, and a workpiece is divided into six processes according to the process, which shortens the cycle of students' rotation processing, and can grasp the quality of students' completion of training tasks at any time, which is convenient for implementation control and adjustment of training tasks and progress. In a word, this training, led by leaders and with the cooperation of students, is convenient for teachers to arrange training management and training tasks. In addition, the management methods and measures of this training are in place, thus achieving ideal training results. Experience of lathe work practice model essay 4

Two-week metalworking practice. During this period, we were exposed to the basic operation skills of machining. With the patient and meticulous teaching of teachers and our active cooperation, we did not have a major injury accident, basically reached the expected internship requirements and successfully completed the internship task.

Before the internship, I heard from my classmates that I was tired, but on the first day of the internship, I still came to the internship center with excitement and curiosity. I looked at the huge machines and thought it was difficult to operate them. I wonder if I can operate it after the teacher has taught me. In short, a few uneasy, a few expectations. Our classmates are probably also curious, touching here and there on the machine. Next, the teacher told us the basic task and purpose of this internship, and repeatedly emphasized the safety issue. Finally, there are lectures and demonstrations.

We mainly studied lathe work. As soon as we entered the operating room and saw the lathe, we knew that it should not be easy to operate. As a result, the teacher also said that lathe work was the most difficult. I told myself at that time that my hands-on ability was not strong, so I must listen carefully! Lathe uses the rotation of the workpiece and the linear and curved motion of the cutter to process the workpiece. As far as the basic content of its work is concerned, it can turn the excircle. Inner circle, end face, cutting, grooving, inner and outer cones, various threads, knurling and forming surfaces, etc. After the teacher's introduction, I know that the installation of turning tool must pay attention to the following points:

First, the protruding length of turning tool clamped on the tool holder should be as short as possible to enhance its rigidity. Second, the number of gaskets under the turning tool should be as small as possible and placed neatly. Third, the turning tool tip should be at the same height as the lathe spindle center.

Installation of workpieces:

First, the extension should not be too long, which will affect the clamping rigidity.

second, the clamping must be firm and reliable to prevent the workpiece from flying out and hurting people. If necessary, use an afterburner.

thirdly, pay attention to alignment and tightness when clamping blank workpieces. At the same time, there are also methods of cutting three elements, selection of cutting parameters, excircle, end face and step of hand-driven car. Finally, the teacher also talked about the internship task and introduced the process steps of processing this part. I listened carefully for fear of missing a little bit. Finally, it was demonstrated on the operating machine, and I also watched it carefully. The teacher's task is completed, and then it's our turn to operate it ourselves. We work in groups of three, and each of us has to process a simple part.

At the beginning, we were not familiar with the machine tool, which led to our slow processing and frequent mistakes. Because the machined parts require high precision of the parts, if we accidentally produce waste products, we have to do it again. After a long processing time, we gradually became familiar with the machine tool, and the processing speed was obviously faster, and the accuracy was also obviously improved. Finally, three qualified parts were processed the next afternoon.

in the next three days, the teacher gave us the task of machining a more difficult part with higher accuracy. Because of the previous foundation, our machining speed is much faster, but it should be more accurate and higher. Because of the previous foundation, our machining speed is higher, so we often produce waste products. Through hard work, under our careful processing, the task was completed and the parts were successfully made.

Because the machining was standing, we were all very tired after two weeks, but we lived a full life. During these two weeks, we still learned a lot.

1. Knowing the knowledge of mechanical manufacturing process and the application of new processes, new technologies and new equipment in mechanical manufacturing has cultivated, improved and strengthened our engineering practice ability, innovative consciousness and innovative ability.

2. Machining practice has cultivated and exercised us, improved our overall comprehensive quality, made us not only have a deeper understanding of the significance of machining practice, but also improved our practical ability. Make us better combine theory with practice and consolidate what we have learned.

3. At the same time, we also learn the teachers' dedication and rigor. Some teachers will show students how to operate again and again until the students really understand. During the internship, we also carried forward the spirit of unity and mutual assistance. Male students helped female students and students with strong hands-on ability to help students with weak hands-on ability. Everyone helped each other learn from each other, not only learned how to cooperate, but also strengthened the friendship between students.

4. The results of our work during the internship. These once incredible small parts were actually processed by themselves, and this sense of pride and accomplishment is hard to express in words.

machining practice has made me feel the pain and joy of being a worker, and at the same time tested my knowledge. Machining practice has made me deeply understand the meaning of life.

Labor not only transforms the natural world, but also transforms one's mind. After this week's internship in machining, I also have a deep understanding in this respect.

1. Labor is the most glorious. Only by practicing can we appreciate the bitterness and fun of labor.

2. Be persistent, careful and patient.

3, serious and responsible, pay attention to safety.

4. As long as you pay, you will get something.

Practice is the test standard of truth. Through a week's metalworking practice, I learned a lot of common sense, and I also got a mental exercise, which is both bitter and happy, which is another precious thing in my college life.
