Summary is a kind of written material that reviews, analyzes and evaluates a certain period, a certain project or a certain work after it has come to an end or been completely completed, so as to learn lessons and some regular knowledge. It's a good way to increase talents. It's time to write a summary. How is the summary generally written? The following is my personal professional technical work summary (5 selected articles) collected for you, hoping to help you.

Summary of Personal Professional and Technical Work of Electrician Technician (5 selected articles) 1 Since I joined the work, I have continuously strengthened my self-cultivation, strived to improve my ideological and moral level, earnestly deepened the study of various cultures and professional knowledge, constantly explored new knowledge, made pioneering efforts, actively carried out various tasks within my intellectual scope, and fully performed my duties as a technician, which played a good role as an example. Taking an active part in technical exchanges and scientific and technological innovation activities, Dida has done a good job of passing on, helping and leading, and fully fulfilled various tasks and indicators assigned by superiors, which has played its due role in the company's production development. I will summarize my professional and technical work since I took office as follows:

First, consciously strengthen theoretical study and strive to improve personal quality.

Without a firm and correct political direction, there will be no positive guiding ideology. In order to constantly improve my political and ideological quality, I have been paying close attention to national affairs and domestic and international situations in recent years, analyzing the impact of changes in the situation on enterprises, and putting this idea into practical actions in the production process to ensure that I am always consistent with the party and enterprises in thought and action. At the same time, I also bring this idea into my work and study, and constantly pursue my own progress. Some people say that if a person wants to become a talent, he must be a man first, which makes sense. In other words: if a person wants to succeed in his career, he must first learn how to be a man! Especially those who do our highly technical work, we should look at things attentively, concentrate on things and learn with an open mind. There is no room for carelessness and mistakes. First of all, we should have a correct working attitude, good professional quality, be serious and responsible for our work, obey the arrangement of leaders, listen to others' opinions and suggestions with an open mind, unite colleagues, be polite to others and serve warmly.

Second, correct working attitude and play a leading role.

Since I joined the company, I have been engaged in all mechanical and electrical affairs, including safety and quality supervision and inspection during all infrastructure construction. I am well aware of the importance of electromechanical management during construction, especially including most invisible electrical infrastructure and projects. It is necessary to supervise and inspect at any time. When you find a problem, you have to solve it. Otherwise, the future trouble will be endless and will never be eradicated. This is a test and responsibility for our electromechanical management. As the monitor of the electromechanical class, as an electrician, I am duty-bound to bear the responsibility and burden. So in my usual work, I not only ask my team members to be careful in supervision and inspection, but also know that it is necessary to be hard while the iron is hot. I put forward some strict requirements for myself:

First, when you encounter dirty, tired and dangerous work, you should walk in front of the workers and do more and more effectively than the workers;

Second, when encountering technical difficulties, we should stand up and try our best to overcome them; I always insist on doing everything well and putting the interests of the company first. Including the production process after completion, sometimes dozens of electrical equipment failures, large and small, are handled against time, which has won valuable production time for the company, laid a solid foundation for the company's development, and provided a strong backing and strong guarantee for the company to create economic and social benefits.

Third, I ask myself to take responsibility; I think since I am a technician, I should be better than ordinary workers in many aspects, such as business level. When the company assigns tasks, ordinary workers should take the initiative to undertake difficult tasks, and can't shirk their responsibilities with workers. They should shoulder the burden bravely like teachers. Usually, I not only ask myself this way, but also do it according to these requirements in practice. Therefore, my performance has been well received by the company's leaders and employees, played my due role as a technician, and established a good image of technicians.

Third, strengthen business study and improve technical level.

Never too old to learn is my motto. Today, with the continuous development of science and technology, you will fall behind if you don't study for a day. Especially electrical automation, no one can fully grasp everything. It is constantly developing and updating, just like computer software, it is updated every day and has been developing. Maybe you knew it yesterday, but it will be different in two days, and more advanced things will be put in. So I usually read more professional books as long as I have time. Over the past year, I have collected a large number of new professional books and materials, constantly enriching myself and mastering new knowledge. For example, electrical design and drawing, electronic technology, modern frequency conversion technology, DC application in industry and so on. In the process of learning this knowledge, I learned a lot of new knowledge, such as PLC programming control principle, ABB inverter setting and control principle, SIPMOS high-power bidirectional thyristor control principle and so on, which really benefited me a lot! Not only did I broaden my knowledge, but also greatly improved my technical level, which also made me interested in learning higher-level theoretical and technical knowledge.

Fourth, carry out skills exchange and realize socialized service.

In the usual work, I often have technical discussions and exchanges with other employees, share what I have learned with everyone, and learn what I don't know from others to make progress together. In addition, I am often invited to other units to help solve technical problems in my spare time, involving thousands of kilometers, including more within the scope. I have been to five counties and three cities. This is inseparable from my spare time to learn high-voltage substation technology and secondary control technology. I fully combine theory with practice, constantly accumulate experience and constantly study new business, so that my skill level has reached the level of proficiency and ease of use. It is embodied in the following aspects: 1. I have mastered the design and installation technology of a series of high and low voltage power transformation and distribution projects of 35KV and below, and can undertake it independently. I have personally completed countless large and small power transformation and distribution projects. For example:

1. My previous work unit was in a well-known group in the city, and in her subsidiary, I personally took charge of most high and low voltage power transformation and distribution projects with the capacity of 50KVA to 1500KVA.

2. In recent years, I worked part-time in a power equipment supporting factory and two transformer factories to do technical support and installation. I personally installed more than 100 box-type substations, various high and low voltage switchgear, and 100 industrial and mining electromechanical control cabinets.

To sum up, I feel worthy of the glorious title of technician! But as a technician, I can't be narcissistic now. I still have to constantly strengthen my study and learn from each other. Only in this way can I keep up with the pace of the times, make steady progress and better serve enterprises and society.

Personal professional and technical work summary of electrician technician (selected 5 articles) 2 My name is xx, and I am an employee of xx power supply company. I am currently the monitor of substation maintenance class of xx power supply company. Joined xx Power Supply Bureau in 20xx. From xx to xx, I am responsible for the management and maintenance of rural high and low voltage lines and distribution of power supply station, and from xx to xx, I am responsible for the maintenance of substation relay protection, investigation and test, secondary project construction and installation. I have been the monitor of the substation maintenance class since xx, and I am responsible for the equipment maintenance, maintenance, electrical test, relay protection, substation engineering construction and equipment transformation of the 17 substation under our jurisdiction. Obtain advanced work certificate. Looking back on many years of work practice, I summarize as follows:

First of all, carry out relay protection setting (1 10kv and below).

Since xx, due to the shortage of original setting personnel, I have assisted the company in setting relay protection for 1 100 kV distribution lines (including capacitors) and 1 100 kV subscriber stations. From the beginning of work, I have established relay protection setting files, such as system impedance table, branch impedance diagram, system station value list summary (branch line), user station and so on. The fixed value sheet is printed by microcomputer and managed in a standardized way, including the calculation basis and process of each reset fixed value, forming a relatively perfect fixed value setting calculation management data. In recent years, the setting and auditing of outgoing lines of newly-built 1 10kV and 35kV substations have been completed. There is no false setting phenomenon, and the calculation of system short-circuit capacity provides a basis for the selection of distribution line switches and other equipment. At the end of xx, due to the change of institutional setup, the junior technicians were instructed to set the fixed value and successfully completed the handover.

Second, participate in power grid construction and transformation.

Since xx, I have participated in the work of increasing the capacity of main transformers and replacing 10kv vacuum switches in several 35kv substations in xx. As the main personnel, I cooperated with the leaders in the whole construction of xx1110kV substation, participated in the overhaul and reconstruction of XX1110kV lines, cooperated with the reconstruction project of XX110kV lines, and gradually became familiar with the equipment and working procedures in my work. Assist to complete the project establishment, compile the feasibility report of substation construction and transmission line transformation, participate in project quality acceptance and data collation, improve power supply capacity, meet the needs of economic operation, reduce line loss, improve power supply reliability and power quality, meet the requirements of economic development for electric power, and achieve good economic and social benefits.

Third, boldly participate in professional operation management and participate in the formulation of professional management system.

I am good at writing because I studied liberal arts before. The unit leader learned that I was transferred to cooperate with the improvement and revision of the participation system. Comprises a power supply equipment maintenance management system; Measures for the administration of technical transformation and overhaul projects; Detailed rules for the implementation of the Measures for the Administration of Fixed Assets; Power supply equipment defect management system; Operational analysis system; Provisions on the management of outsourcing projects; Regular production meeting system; Line and substation maintenance inspection system; Measures for the management and reward of technological progress; Scientific and technological progress and rationalization proposal management system; Detailed rules for the implementation of technical supervision, management and assessment; Presided over the compilation of the basic system of power distribution management in power supply stations. Participate in formulating production management standards, including: voltage and reactive power management standards; Line loss management standard; Management standards for economic activity analysis; Management standards for the whole process of equipment; Presided over the formulation of professional management responsibility system: line operation professional work management network and personnel responsibility system at all levels; Professional work management network and personnel responsibility system for transformers at all levels; Lightning protection management responsibility system; Work management network and personnel responsibility system at all levels of cable operation specialty; Detailed rules for implementation of transformer countermeasures. Actively carry out seasonal work, and arrange and deploy annual energy-saving work for important festivals and major political activities. The development of these works has effectively promoted the safe and stable operation of the power grid.

Fourth, carry out science and technology management.

At work, I try to use computers in management to improve work efficiency and management level.

1. Use the fixed assets statistics application to complete the transportation of the company's fixed assets, and complete the work of adding, changing, scrapping and depreciating the fixed assets.

2, the application of technical transformation statistical program to complete the statistical analysis of technical transformation (including heavy measures, general technical measures).

3. Assist the development and application of the company's geographic information system, organize the input of distribution line parameters and operation data, and form a line database.

4. Assist to carry out the pilot work of automatic reclosing of distribution lines, form an automatic fault judgment barrier, improve the reliability of power supply, and make a useful attempt for distribution line automation.

Five, actively participate in business training, strengthen their business skills, improve safety awareness.

Over the years, I have actively participated in the training and examination of simulator training, electric shock first aid, and knowledge adjustment of Safety Regulations organized by our company. In all previous studies and trainings, I have always been open-minded and eager to learn, and I am not ashamed to ask questions. I actively consulted the instructor, worked hard on my basic skills, and refined my own business, so that my thoughts always centered on "all for safety in production is to be responsible for my personal safety", which also improved my awareness of safety in production and added a safety guarantee for my operation.

I deeply realize that safety in production is no small matter. Once there is any negligence in safety work, all the work will be in vain. If you want to do a good job in the safe production of substations, you should not panic, confuse your own thinking, misjudge the fault phenomenon and give your brain a clear and correct understanding under any circumstances! In production work, sometimes experience is more reliable than glib words and rhetoric; However, this is also the accumulation result of constantly learning the knowledge of safety production and improving their own skills.

Six, actively study the case of production safety accidents, organize safety team activities, always alert yourself, nip in the bud.

Thanks to the love of leaders and colleagues at all levels in my years of work, let me cooperate with the team to carry out and organize safety activities four times a month. In the meantime, there are my efforts and efforts, as well as my experience and happiness in harvesting safe production. In every bloody accident case, the victim of the accident may just disobey the rules and procedures, but he has to pay the price of his own life; Or just fail to inspect the equipment according to the requirements of safety regulations, which may cause the main transformer to trip and lose load; On the one hand, it will affect the company's good reputation, on the other hand, it will also cause inconvenience and psychological panic to the public.

The above is a technical summary of my own work over the years, and summing up experience lies in better self-improvement. I will encounter all kinds of problems in my future work and life, and I still have many shortcomings. I hope I can get the guidance and instruction from all teachers and colleagues.

Summary of personal professional and technical work of electrician technicians (5 selected articles) 3. Several examples of troubleshooting of common voltage appliances

1, voltage circuit breaker failure

Contact overheating, can smell the smell of power distribution control cabinet. After inspection, the moving contact is not completely inserted into the static contact, and the contact pressure is not enough, which leads to the decrease of switch capacity and overheating of the contact. At this time, the operating mechanism should be adjusted so that the moving contact is completely inserted into the static contact.

When electrified, flashover and explosion occur due to long-term overload and poor contact. When repairing this fault, we must pay attention to safety to prevent electric arc from harming people and equipment. After the load and contacts are overhauled and the no-load power supply is normal, the operation can be checked with load until it is normal. This kind of fault must pay attention to the daily maintenance of the equipment to avoid unnecessary harm.

2, contactor failure

Out-of-phase contact, poor contact of a certain phase or loose terminal screws lead to out-of-phase operation of the motor. At this time, the motor can rotate but hum. Stop the car immediately for maintenance.

When the contact is welded and the stop button is connected, the motor will not stop rotating and may hum. This fault is the welding phenomenon of two-phase or three-phase contacts due to large overload current, so the power supply should be cut off immediately and the contactor should be replaced after checking the load.

An energized armature does not attract. If there is no vibration and noise when electrifying after inspection, it means that the moving part of armature is stuck, but the coil is broken. The detachable coil is rewound according to the original data and dipped in paint to dry.

3, thermal relay failure

The mechanical equivalent of the heating element is burnt out. If the motor can't start or there is buzzing when it starts, it may be that the fuse in the thermal element of the thermal relay is blown. The reason for this failure is that the operating frequency of thermal relay is too high or the negative side is overloaded. After troubleshooting, replace the appropriate thermal relay, and readjust the set value after attention.

Thermal relay misoperation. There are several reasons for this failure: the setting value is too small, so that there is no overload when acting; The starting time of the motor is too long, which makes the thermal relay act during the starting process; The operating frequency is too high, so that the thermal elements are often impacted. Re-adjust the set value or replace the appropriate thermal relay to solve the problem.

Thermal relay does not work. This kind of fault is usually that the current setting value is so large that it does not act for a long time after overload. The set current should be adjusted according to the working current of the load.

Thermal relay has been used for a long time, so its operation reliability should be checked regularly. When the thermal relay trips, it should be reset after bimetal cooling. Do not press the reset button too hard, otherwise it will damage the operating mechanism.

Second, troubleshooting and essentials of common voltage appliances

Any voltage apparatus with contact action is mainly composed of contact system, electromagnetic system and orphan arc extinguishing device. It is also the focus of maintenance.

1, contact troubleshooting.

Contact failure generally includes contact overheating, fusion welding, etc. The main causes of contact overheating are insufficient contact pressure, oxidized or unclean surface and insufficient capacity. The main reason of contact fusion welding is that when the contact is closed, a large arc is generated, and the contact jumps seriously.

Check the contact surface for oxidation and dirt. There is dirt on the contact, which has been cleaned with gasoline.

The oxide layer of silver contact not only has good conductivity, but also will be reduced to metallic silver in use, so it cannot be repaired.

If there is an oxide layer on the copper contact, you can file it with a smooth file or scrape off the oxide layer on its surface with a knife.

Observe whether there is burn or singeing on the contact surface. The singeing of copper contacts can be trimmed with a smooth file or knife. The repaired contact surface does not need to be too smooth, and it is not allowed to be repaired with abrasive cloth, so as to avoid the residual sand grains embedded in the contact when the contact is closed, causing poor contact. But the silver contact singeing does not need to be repaired.

If the contact is welded, the contact should be replaced. If it is caused by insufficient contact capacity, an electrical appliance with larger capacity should be selected for replacement.

Check whether the contact is loose. If it is loose, tighten it to prevent the contact from jumping off. Check whether there is any mechanical damage on the contact to deform the spring, resulting in insufficient contact pressure. If so, the pressure should be adjusted to make the contacts contact well. The empirical measurement method of contact pressure is as follows: When measuring the initial pressure, put a piece of paper between the bracket and the moving contact, the width is about 0. 1mm, which is wider than the contact, and the paper is compressed under the action of the spring. At this time, pull the paper with one hand. When the paper strip can be pulled out and feels strong, it can be considered that the initial pressure is more appropriate. For the measurement of final pressure, the paper strip is sandwiched between dynamic and static contacts, and when the contacts are energized and attracted, the paper strip is stretched at the same square farad. When the paper can be pulled out, the final pressure can be considered as appropriate. For large-capacity electrical appliances, such as 100A or above, when the same square farad paper strip is used, it can be considered that the initial and final pressure when the paper strip is pulled out is more suitable.

The above-mentioned contact pressure measurement method has achieved good results in many repair tests. Can be carried out normally. If the measured pressure value cannot be recovered by adjusting the spring, the spring or contact must be replaced.

2. Troubleshooting of electromagnetic system

Due to the poor contact between the end faces of the moving and static iron cores, the iron core is skewed, the short-circuit ring is damaged, the voltage is low, the armature noise will be great, and even the coil will be overheated or burned.

(1) The armature is noisy. When repairing, remove the coil and check whether the contact surface between stator core and stator core is smooth and free of oil pollution. If it is uneven, it should be filed or smoothed; If there is oil stain, clean it with gasoline.

If the moving iron core is skewed or loose, it should be corrected or tightened.

Check whether the short-circuit ring is broken. If the short-circuit ring is broken, the copper plate should be replaced according to the original size, or the thick copper wire should be made into a square section and installed according to the original size.

(2) After the electromagnetic coil is cut off, the armature is not released immediately. The main reasons for this failure are: the moving part is stuck;

The air gap of iron core is large and the remanence is too large; Spring fatigue deformation, lack of elasticity, oil pollution on the contact surface of iron core. After disassembly and renovation, an air gap of 0.02-0.03 mm can be left between the end face and the bottom end face of the iron core, and the spring can also be replaced.

(3) Troubleshooting of the coil. The main fault of the coil is that the current passing through it is too large and the coil is overheated and burned.

This kind of fault is usually due to the damaged insulation of the coil, low power supply voltage and poor contact between the moving and static cores, which will also make the coil current too large and the coil overheat and burn out.

If the coil is burned due to short circuit, it should be rewound. The diameter and number of turns of the wire can be measured from the burnt coil. You can also find the wire diameter and turns of the coil from the nameplate or manual. According to the cross section of the wire core, make the wire mold. After winding the coil, put it in the oven of 105- 1 10℃ for 3 hours, cool it to 60-70℃ and dip it in 10 10 asphalt paint or use other insulating paint. After dripping the remaining paint, dry it in an oven at 1 10- 120℃, and then cool it to normal temperature before use.

If the number of turns of the coil is short-circuited. The short circuit point is close to the coil head, and the rest are in good condition. Cut off the power supply immediately to avoid burning the coil.

If there is no vibration and mechanical noise after the coil is electrified, check that the connection of the lead-out wire of the coil does not fall off, and use a multimeter to check whether the coil is broken or burned out; If there is vibration and noise after power-on, check whether the moving parts are stuck, whether there is a conductor between the static and moving cores, and whether the power supply voltage is too low. We should treat them differently and deal with them in time.

3. Maintenance of fire extinguishing device

Remove the arc extinguishing cover, check the integrity of the arc extinguishing blade, and remove the smoke marks and metal chips on the surface. The shell should be intact.

If there is a crack in the arc extinguishing cover, it should be replaced in time. In particular, it is pointed out that the original electrical appliances with arc extinguishing cover should not be used to prevent short circuit without arc extinguishing cover.

There are many kinds of commonly used low-voltage appliances. The above are some typical and commonly used methods and essentials to deal with electrical faults, which are similar to others and have certain * * * for the maintenance of other electrical appliances.

Since I transferred to Beilun Intermodal Transport Class, I have participated in the commissioning acceptance of 9 1 10KV substations and the commissioning of several 35KV substations. The above is a summary of my work.

Summary of Personal Professional and Technical Work of Electrician Technician (5 selected articles) 4 Being able to adhere to the principle of "safety first, prevention first" in long-term work practice, strictly implement various rules and regulations of safety production, take the initiative to give full play to subjective initiative based on their own posts, insist on strict demands on themselves based on standardized posts, and complete production tasks with good quality and quantity.

Solid style, hard-working. Be able to carry out all the work in strict accordance with the requirements, procedures, systems and measures of the specification, persevere when encountering difficulties, take the initiative to overcome the difficulties faced, and complete all the tasks assigned by the leaders. At the initial stage of the workshop merger, the newly established _ _ power workshop had incomplete working facilities and the workshop office network could not be used. In order to transmit the production information in time, I connected the communication equipment myself, which ensured the smooth flow of production information. In _ _ _, our section conducted centralized maintenance for catenary for the first time. As an electrician, the compilation of centralized maintenance scheme for catenary shows tenacious professionalism from learning to application, from ignorance to gradual understanding.

Consciously strengthen the study of theory and business, integrate theory with practice, and serve the workshop safety management. In daily production and life, I insist on working hard on diamond business technology and modern scientific and cultural knowledge, constantly improve my theoretical level, professional ability and quality cultivation, pay attention to applying what I have learned to safety production practice, cooperate with workshop leaders to do a good job in production management, and make contributions to first-line production. _ _ _ _ At the beginning of the year, in the fight against freezing rain and snow disasters, we actively grasped the dynamic information of frontline work, made statistics, summarized and reported materials on the emergency repair and equipment operation in a timely manner, provided first-hand information for the leaders to understand the situation on the spot, and quickly conveyed the instructions from the superiors. No matter the emergency repair or the normal inspection of equipment, we persisted in completing all kinds of summary and statistical materials reporting work day and night.

Team management and construction work, independent. Since taking on the management of workshop team construction, I have been able to closely focus on the safety theme, combined with the safety management of the team, be diligent in thinking, be brave in exploration, be loyal to my duties, dare to grasp and manage, dare to act boldly, listen to the opinions of team workers, obey the arrangement of workshop leaders, persist in doing what should be done, actively find out the reasons for the gap, adjust working methods, constantly sum up experience and improve the quality of work.

The equipment in the power supply workshop is scattered, and the daily work of team management is complicated. Pantograph network, hydropower and other professional teams have it. It is undoubtedly quite difficult to distinguish different types of teams and carry out relatively unified management, which requires more labor. Therefore, they often work day and night without rest.

Summary of Personal Professional and Technical Work of Electrician Technician (5 selected articles) 5 Since the beginning of this year, under the care and correct leadership of leaders at all levels, with the cooperation and help of workers, I have worked hard to do a good job in the maintenance and maintenance of power stations and the maintenance of equipment in a down-to-earth manner. Actively carry out all work within the scope of functions, fully perform the duties of a technician, and play a good role as an example. Successfully completed the tasks and indicators arranged by the superior leaders, which played a certain role in the construction of the company's power station work. The work in 2008 is briefly reported as follows:

In, due to the company's production needs, our company set up an electric hoist department, a bridge crane department and a cold-rolled strip production line, which were 150, 120 and 175 respectively. Pickling production line; There are also many installation equipment required for strip steel power consumption. Therefore, the task of equipment maintenance, spot check and inspection is heavy. To this end, I stick to my post, strive to overcome difficulties, overcome sharp drilling problems, solve difficult projects, and actively carry out equipment maintenance.

First, lay a solid theoretical foundation and strengthen capacity building.

In this year's work, I first strengthened my ideological and political study and professional study. I actively participated in all kinds of study work organized by the company, strengthened my theoretical foundation, deepened my understanding and use of the company's power station equipment, and improved my business ability. Effectively sum up the previous year's work experience, explore and innovate on the basis of practical work, and strive to improve technical quality and work ability.

Second, stick to post responsibilities and solve problems.

In this year's work, I deeply realized the importance of power station equipment for the production and construction of our company. Therefore, I carried out all kinds of equipment maintenance work in time, effectively solved all kinds of equipment problems in the maintenance process, and earnestly carried out technical transformation work. In the work, solve the difficult problems on site in time, carefully study and explore solutions, and break through technical barriers in combination with previous work experience to ensure the normal operation of equipment.

Third, overcome work difficulties and improve the effectiveness of post work

In this year's work, I pay close attention to the actual work, strictly abide by the company's various work systems, persist in doing my job seriously, and effectively guarantee the normal operation of the company's equipment. In my work, I give full play to my professional skills, actively carry out technical transformation and innovation in combination with the actual work in the strip workshop, and strive to reduce costs and increase efficiency by repairing the old and utilizing the waste.

In this year's work, our company has carried out a comprehensive technical transformation. This year 1 month, according to the company's requirements, I actually carried out the installation, wiring and debugging of the electrical equipment of the blue strip steel production line (high-strength packing belt). I strictly ask myself to strengthen my understanding and mastery of the newly installed equipment, and strictly carry out the installation and maintenance work, thus ensuring the successful commissioning of the newly installed equipment this month.

In May this year, according to the requirements of the company, I put myself into the installation and debugging of the spring steel production line (ultra-high-strength packing belt). Because the installation and debugging of this equipment need high technical content, in order to do this work well and complete the investment of our company's newly installed equipment, I actively learn from the manufacturers, solve various technical problems in debugging with them, and make unremitting efforts to complete the equipment debugging work. In this month, through my unremitting study and research, my XX group successfully installed the electrical equipment of wire cutting CNC machine tools and polishing machines, completed the corresponding wiring work, and conducted debugging work with manufacturers. Although the installation and debugging of new equipment is complicated, I am not familiar with the equipment, and I have encountered some difficulties and obstacles in the installation and debugging of the equipment, but I still stick to my post, actively study and study, and persistently solve various problems encountered in the installation and debugging of the equipment. In March this year, I continued to debug the spring steel production line with the factory staff, which laid a solid foundation for further improving our equipment and ensuring the normal operation of our company's production work.
