Is it good to do CNC technology?

To be honest, it's really bad, I just studied CNC major, in school is relatively good, now graduated, only to know that I learned the wrong major, some small factories simply do not use CNC beds, manual is enough, by the way, manual machine tools can do you dead, some large factories are a lot of CNC machine tools, but the programs are numbered, you go just like the robot loading and unloading parts, and like these machinery industry to do the master to five or six years or even more than ten years, If you think you have the patience to learn and wait, then you will learn CNC well, and I personally recommend that you study some management majors, or engineering and design jobs are good.

It is recommended that you don't learn CNC, you don't know CNC.

You don't have to learn, it's useless to learn, it's better to just find a CNC factory to go in and do it.

This major is still very good, so let's introduce what I learned from a friend.

Major in CNC technology.

Cultivate technical application talents who master the basic knowledge and basic theory of CNC technology application, have the ability to program and operate CNC machine tools, engage in modern production organization and management of CNC machining technology, and develop morally, intellectually and physically.

Graduates of this major are mainly engaged in the operation of CNC production lines, the programming of CNC machining, process implementation, installation and commissioning, maintenance management, and technical services of CNC products in various machinery manufacturing enterprises.

CNC technology is a set of mechanical, electrical, hydraulic, optical, computer, automatic control technology as one of the knowledge-intensive technology, it is the manufacturing industry to achieve modernization, flexibility, integrated production basis, but also to improve product quality, improve productivity of the indispensable material means. Japan, the United States, Germany and other industrially developed countries.

The economic benefits obtained by using numerical control technology.

Roughly: the number of operators is reduced by 50, the cost is reduced by 60, the machine tool utilization rate is 60-80, the number of machine tools is reduced by 50, and the production area is reduced by 40. Due to the wide application of CNC technology in the world's manufacturing industry, ordinary machinery is gradually replaced by high-efficiency and high-precision CNC equipment.

The wide application of numerical control technology in the machinery manufacturing industry has become a powerful driving force for the development of the national economy. Accession to the WTO.

Later, with the rapid development of the economy, China is gradually becoming the "world manufacturing center", and the numerical control rate has become one of the important indicators to measure the manufacturing technology level and economic strength of a country or enterprise (numerical control rate: the proportion of CNC equipment in the number of equipment owned).

At present, the numerical control rate of machine tools in China is only, while Japan is as high as 30, and the United States is more than 40. CNC machine tools have been widely used in developed countries, and the application and promotion of CNC technology in China is far behind that of developed countries. China will increase 40-500,000 CNC machine tools in a few years, and 60-800,000 CNC specialties will be needed accordingly.

Technical talent.

CNC is more tired, but it is a necessary stage, tired after gaining experience is their own, they can teach others to open machine tools, their own programming, not tired.

Numerical control, also known as computer numerical control, is a technology that uses digital information to control mechanical movement and processing process, and is mostly used in automated production, CNC machine tools, robotic arms and other fields.

Advantages and disadvantages of CNC machining:

1. Greatly reduce the number of tooling, and do not need complex tooling for processing parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part plus macro work procedure, which is suitable for new product development and modification.

2. The processing quality is stable, the processing accuracy is high, and the repeatability is high, which can meet the processing requirements of the aircraft.

3. In the case of multi-variety and small-batch production, the production efficiency is higher, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.

4. It can process complex surfaces that are difficult to be processed by conventional methods, and even some processing parts that cannot be observed.

The disadvantage of CNC machining is that the machine tool equipment is expensive, and the maintenance personnel are required to have a high level. <>

The employment prospects for CNC technology majors are very broad. For college students in today's society, the employment prospects are already very good compared to other professions. CNC technology is a knowledge-intensive technology integrating mechanical, electrical, hydraulic, optical, computer and automatic control technology.

It is the basis for modern, flexible and integrated production in the manufacturing industry, and also improves the quality of products. An important means of increasing productivity. At present, the numerical control rate of machine tools in China is only, while Japan is as high as 30, and the United States is more than 40.

In developed countries, CNC machine tools have been widely used, and the application of CNC technology in China is far from developed countries. China will add 400,000 to 500,000 CNC machine tools in a few years, which is equivalent to 60 to 800,000 CNC professional and technical personnel. The employment prospects of CNC technology rank 94th among all majors, and students who graduate from CNC technology have an average monthly salary of about 4,986 yuan, a minimum salary of about 2,857 yuan, and a maximum salary of 10,000 yuan.

CNC is not difficult. It is easy to learn CNC software programming, the key is that the process is difficult, and the processing technology depends on practice, if you don't actually operate the machine tool for a few years, it is difficult, just like a chef who can only carve and not stir-fry! Very limited.

CNC industry prospects:

Clause. 1. CNC programmer. Many machining companies use automatic programming to generate CNC machining programs, so they need to learn CAM software.

Different units use different CAM software, and there are many types, but in general, the processing methods are similar, so you must learn one well. But do CNC.

Programmers are demanding and responsible, so they need to have a lot of experience in machining. In this case, it is not realistic for students who have just left school to do this position immediately. It must go through a period of exercise, as short as one or two years, and as long as three or five years.

Clause. 2. Similar majors can also be selected: mechanical design, such as draftsmen, mechanical designers, structural designers; Processing technology management or on-site technicians, mechanical designers (mechanical engineers) CNC machine tool operators, mechanical equipment maintenance workers, mechanical equipment salesmen, programmers, mechanical technicians, inspectors, production administrators.

The first disturbance. 3. CNC maintenance personnel or after-sales service personnel. The requirements for this position are higher, which is lacking in numerical control.

It is necessary to have not only a wealth of mechanical knowledge, but also a wealth of electrical knowledge. If you choose this path, it can be very hard (such as frequent business trips), and you have to keep learning and accumulating experience. This position requires more training, so it will take longer to become proficient, but it will also be more rewarding.

Clause. Fourth, CNC sales personnel. The remuneration of this position is relatively generous, and the professional knowledge required is not so much, but it requires outstanding eloquence and good social skills, which is not capable of ordinary people.

Clause. Fifth, you can choose to be a CNC operator, after CNC internship and CNC operation training students can be competent, but the pressure of competition for this job is greater, any engineering higher vocational has this major, not to mention secondary vocational and technical school students. At present, the CNC operation positions in China's machining industry have basically reached saturation.

Some students told me that their classmates had graduated from junior high school and had been doing CNC operations five or six years earlier than them, and they were all skilled workers, and their wages were okay, so they felt very hopeless. I told them that the comparison is not about the present, but about the future. <>
