Research on CNC System

In 2002, "Mechanical Workers" magazine and CNC System Branch of China Machine Tool Industry Association jointly conducted the first CNC system application survey. The survey was called "big hand, big action, big promotion" by industry leaders, and it had far-reaching influence. . Then, after 5 years have passed, how has the pattern of China's CNC system changed? Has the market reshuffled? In the next five years, China's CNC machine tools and CNC systems have entered a critical period of development. How to accurately grasp market information? How will the domestic CNC system industry develop?

To this end, China Machine Tool Industry Association CNC System Branch, "Mechanical Workers" magazine, "Modern Parts" magazine and "China Machinery Industry Yearbook" editorial department jointly held the second CNC system application survey, and the results of the survey Scientific analysis was carried out to provide reference for CNC system manufacturers and machine tool manufacturers to develop product development, production and marketing.

This survey is mainly in the form of a questionnaire. The questionnaire divides the numerical control system into economic type (stepping motor), popular type (servo motor, 3-axis linkage, semi-closed loop control), high-grade type (servo motor, 3-axis linkage or more, full-closed loop control); foreign CNC system, domestically produced CNC systems and investigate them separately. The results of the survey are now published as follows.

Second, the survey group distribution 1. Regional distribution survey target area distribution As shown, the coastal developed East China region is still the most, reaching 43%, the data of Central South (North China, South China), North China and the five years ago basically no change The northwest region has grown from 9% five years ago to 12% now. From this point of view, the northwestern manufacturing industry has developed rapidly, and the number of users using CNC machine tools has also increased.

2. The industry distribution questionnaire divided the machine tool industry and the mechanical processing industry (non-machine tool industry), the machine tool industry accounted for 23%, and the mechanical processing industry accounted for 77%. Most of the survey results reflected the voice of the end user, therefore, the CNC system and machine tools For manufacturers, it can be used as a reference.

3. The questionnaires received by the enterprises in China accounted for 43% of the enterprises in China, 43% of the private enterprises, and 14% of the sole proprietorships/joint ventures.

4. The department in which the department is surveyed is as shown. It can be seen that the proportion from the technical department and the manufacturing department is 65%. They are direct users of the numerical control system, and their speeches are more targeted and representative. In all the feedback questionnaires, 30% of the purchases of CNC systems have decision-making power, 68% of the proposed rights, and only 2% of the irrelevant.

In summary, the groups participating in the survey can basically objectively reflect the application status, existing problems and market development trends of the CNC system.

Third, the application status of the numerical control system 1. The application ratio of the various grades of the numerical control system In order to investigate the proportion of the numerical control system used in different grades, the questionnaire divides them into five sections: 20% or less, 21% 40%, 41% 60%, 61% 80%, 81% or more. For example, if the economical CNC system used by the company accounts for 20%, then the remaining 80% is the medium and high-end system.

Statistics are as shown: Through comprehensive calculations, it can be concluded that the proportion of each system is 30% for economy type, 43% for popular type, and 27% for high-end type. From this point, it can be seen that popular CNC system has become Investigate the focus of user usage. As shown.

2. The brand of numerical control system equipped with different machine tools (1) The foreign brands that are used by high-end users include Fanuc, Siemens, Mitsubishi, HEIDENHAIN, Grid, NUM, etc. The domestic brands used are Huazhong CNC and Aerospace CNC. Kane, and so on. The survey shows that the high-end market is still the world of foreign brands, Siemens, Fanuc, Mitsubishi, etc. have a good performance. A gratifying phenomenon is that domestic CNC systems such as Huazhong CNC, Aerospace CNC, and Kanedi have entered the high-end CNC series and have a certain market share. The domestic CNC system has the opportunity to display its skills in the high-end market.

(2) The total number of questionnaires for popular foreign brands is still more than half, but the market for domestic systems has developed greatly, and the proportion of questionnaires is close to 1:1. Wide number, Huazhong CNC, Kane Emperor, etc. have a good performance.

(3) In the economical numerical control system, domestic systems such as Guangzhou CNC, Huazhong CNC, and Kanedi are ranked in the first echelon, but foreign brands like Fanuc and Siemens have begun to enter this market, and they have a small questionnaire. proportion. During CIMT2007, Siemens introduced the economical 801 CNC system. Mr. Zou Yaxing, general manager of Siemens Motion Control Department, revealed to the media that within five years, Siemens CNC system has a 25% market share in the low-end market. This shows that foreign brands are not only satisfied with the mid-to-high-end market, but the low-end market is also very attractive to them.

According to the Machine Tool Industry Association, in 2006, China's CNC system production and sales of about 100,000 sets, according to the number of sets, foreign brands accounted for about 1/3, domestic systems accounted for 2/3. In domestic systems, 50% are economical CNC systems, especially CNC systems for CNC vehicles account for 80% to 90%.

It can also be seen from the survey that in the economic field, the domestic system has an absolute advantage. While the domestic CNC system stabilizes the low-end market, it also begins to develop into the middle and high-end market and gains a certain market share. From the perspective of the popular CNC system technology, the domestic system can meet the market demand, and the price advantage is obvious, but it still needs to further improve the quality and reliability, gradually establish the brand, cultivate the market environment using the domestic CNC system, and expand the market share of this piece. rate.

3. Service mode What services do users of the CNC system want to receive? The questionnaire lists 5 technical training, on-site service, installation and commissioning, system upgrade and regular maintenance, and the answers can be selected. It is not difficult to see that technical training is still the service that users hope to obtain, and the proportion of users reaches 82%. Technical training is the most direct way for users to use CNC systems. Technical training is well done. Machine operators and technicians are comfortable to use. Naturally, It will form a technical set and advantage, form the habit of using the CNC system, and then have a direct impact on which CNC system to purchase next.

4. What measures will the user take when the system fails? In the course of use, if the CNC system fails, what measures will the user take? The options given by the questionnaire are self-maintenance, factory repair, third-party maintenance and other methods: It can be seen that nearly half of the users have chosen to repair themselves. It is not difficult to understand that the user can solve the technical problems of the numerical control system and must work for it. Great convenience. Therefore, in combination with the above 3 and 4 problems, it is recommended that the system manufacturer and the machine tool manufacturer jointly set up a technical training center to systematically tell the customer how to use the CNC system, maintenance and maintenance, and troubleshooting methods.

5. The evaluation questionnaire of the used numerical control system divides the user's evaluation of the numerical control system into three levels, which are satisfactory, general and unsatisfactory. The content of the evaluation is quality reliability, after-sales service and delivery time. In contrast, the questionnaire will be evaluated separately for domestic and foreign systems.

Compared with foreign countries, domestic CNC systems have a certain gap in quality reliability, which is particularly prominent in high-end systems. The satisfaction with the quality reliability of domestic systems is generally 85%, the dissatisfaction is 15%, and the dissatisfaction with foreign systems is only 1%. One of the main reasons is that the production scale of domestic systems, especially high-end systems, is higher. Small, did not form a "quantity" accumulation like foreign brands, quality problems are mostly exposed in the initial use of users, when the equipment enters the quality stable period, the domestic system can operate normally. Therefore, for domestic systems, quality reliability and market share are like our two hands, both hands must be grasped, both hands must be hard.

4. Factors affecting the user's choice of CNC system The impact factor is divided into price, brand, performance, delivery date, after-sales service and quality reliability. The CNC system is divided into three levels: economic, popular and high-grade. The user sorts the impact factors from high to low. The result takes the first 4 digits and performs weighted analysis on them.

(1) For economical CNC systems, performance and price show equal importance, tied for first place, then quality reliability, brand, after-sales service and delivery. Compared with the results of 5 years ago, current users will consider price factors more when purchasing CNC systems. Why is this? Five years ago, users preferred to consider the quality reliability when purchasing the system, and the price ranked second. After five years, people considered the price factor more, and the quality reliability ranked second. This also shows that China's economical CNC system technology is very mature, users do not have to worry too much when buying, as long as the price is cheap, users can generally accept. It seems that reducing costs to lower prices is the key to economic CNC system manufacturers winning the market.

(2) For the popular CNC system, the ordering is still performance, price, reliability, brand, after-sales service and delivery time, but the percentage of performance is higher than the economy.

(3) When considering high-end CNC systems, users will especially consider performance, quality reliability and price tied for second place, followed by brand, after-sales service and delivery date. The reason is that China's high-end CNC system, especially the 9-axis linkage control capability, has reached or reached the technical level of foreign high-end CNC, breaking the foreign technical blockade, and the price is only 30% 50% of foreign products, and the high-end CNC market is monopolized by foreign brands. Turning to market competition, users have more choices about products, resulting in a decline in the overall price of high-end CNC systems. But at the same time, we must also see that because of the high price of high-end CNC systems, users have put forward higher requirements for their quality reliability.

(4) If we convert performance and price into price/performance ratio, we can see such a result. The factors that users prefer to consider are: cost performance, quality reliability, brand, service and delivery date. From this point of view, the price/performance ratio is the killer of the CNC system to win the market. Quality reliability is always ranked second. If the performance price is right, the user considers whether the quality is too good. This shows that the users of CNC systems in China are gradually maturing. The brand's requirements also reflect this trend. The higher the system grade, the more factors that consider quality and brand. Therefore, when developing domestically-advanced systems, they should pay more attention to promoting the cost performance of their products, paying attention to improving the quality of products and establishing brand awareness. Only in this way can we create a blue sky in the middle and high-end market.

Statistics from the machine tool host factory questionnaire, the conclusion is as follows: the factors affecting the purchase of high-end CNC system are performance, reliability, price, after-sales service, brand; popular and economical are performance, price, reliability, after-sales service, Brand. From this point of view, machine tool manufacturers pay more attention to the reliability of high-end CNC systems and the price of economical CNC systems.

V. Understand the channels of the CNC system. What channels do users mainly use to understand and purchase CNC systems? Understand the purchase channels are magazines, exhibitions, networks, peer recommendation, business promotion, newspapers. Compared with the first survey, the first place is still a magazine advertisement. The difference is that after five years of development, the network has risen from the 5th to the 3rd, showing a strong development momentum. Peer recommendation is still a way that system manufacturers can't ignore, which is due to the comprehensive indicators of the product itself, namely performance, quality reliability, price, service, etc., is a brand effect.

Sixth, purchase intention We know that the user who buys the CNC system is the machine tool manufacturer and the machine tool user, and the machine tool user refers to the machine tool transformation. According to the statistics of the Machine Tool Association, the production volume of CNC machine tools in 2006 was 88 297 units, an increase of 29.2% year-on-year. According to this speed development, the output of CNC machine tools in 2007 is expected to exceed 100,000 units and 100,000 units. The machine tool needs 100,000 sets of CNC systems.

If the company has a system purchase or machine tool transformation demand in the near future, which CNC system will be selected? The survey is unable to count how much demand the user has, but only asks the user what the intention is, which on the other hand reflects the popularity of the CNC system in the market. The questionnaire surveyed the needs of foreign brands and the demand for domestic brands. Statistics show that FANUC, Siemens, Guangju, Huazhong CNC, Mitsubishi, Heidehan, Kanedi, Fagor, NUM, Aerospace CNC, Nanjing Huaxing Nanjing Renhe, Guangtai, Lantian, Kaiqi, Xinfangda, Kaitong, Shengwei, Dasen, Dongfang, etc. all have different user needs.

According to the statistics of domestic and foreign brands, among the foreign brands, FANUC and Siemens are still the focus of users' choice. The proportion of questionnaires exceeds 30%, and Mitsubishi also exceeds 15%. Among domestic brands, the number of Huazhong and Huazhong CNC exceeds A 30% questionnaire ratio.

Seventh, the user's heart-to-hearted domestic CNC system has been embarking on a new development track. What do users have about the domestic system? Among the feedback questionnaires, nearly 600 questionnaires provided pertinent opinions and suggestions to domestic system manufacturers. More than half of them hope to improve the performance and quality reliability of domestic CNC systems. This is the basis for the development of domestic CNC systems. . At the same time, domestic systems should also improve the ability of after-sales service and improve service methods. Domestic systems have factors of time, location, and people. There is no reason for service in comparison with foreign countries. The survey shows that the domestic system has made great progress in terms of service, but some users are still not satisfied, and the service still has a lot of room for improvement.

Here are some suggestions and comments from users. Here are a few excerpts: A Beijing user said: Performance and reliability are prerequisites, and prices and services are guaranteed.

A Henan user said: In the grades to be further improved, the panel design should pay attention to ergonomics, reliability should be improved.

A Chongqing user said: The upgrade and transformation of the CNC system should be more connected with the manufacturer, and the maintenance information should be made public. The CNC system should be more practical, not too fancy, it is best to have a USB interface.

A Hubei user said: manufacturers should arrange more training after the sale, so as not to reduce the manufacturers to come over for repairs due to a little glitch, resulting in cumbersome after-sales service.

A Hunan user said: Be a good person, be reliable, make a domestic system, come on! For more comments and suggestions, please visit China Metalworking Online at

Eight, customer satisfaction brand After user voting and expert consultation, we have rated the user satisfaction brand, they are: domestic: Guangzhou CNC, Huazhong CNC, Kanedi CNC, Aerospace CNC, Nanjing Huaxing CNC, Chengdu Guangtai and so on.

Foreign countries: FANUC, Siemens, Mitsubishi, HEIDENHAIN, Grid, NUM, etc. I hope that these companies can live up to the expectations of users and continue to provide the market with the highest performance, the best price, the most reliable CNC system, and make greater contributions to China's CNC industry.

IX. Conclusion The second CNC system application survey did not subdivide the application industry of CNC systems such as automobile manufacturing and aerospace, so it is impossible to analyze these industries, and hopes to focus on future investigations. The design of the questionnaire also needs to be further refined to improve the scientific nature, so as to investigate what the system manufacturers want to know.
