How to buy a machine in a rapidly changing situation
With the recovery of the global economy, China will also join the WTO. The development of the western region is in full swing. New market opportunities and challenges have already been faced. There is no doubt that the new round of machine tool market fever is coming, but will it be the kind of overheating in the early 1990s? What kind of machine tools are better to sell? I don’t think so, because of the user’s system, management, and technology level. . In these ten years of ups and downs, it has greatly improved. Of course, in the face of all the temptations of the market, some imitations and mistakes are inevitable. So take precautions. Lifting your mind and tidying up your ideas may help. After China's accession to the WTO, the domestic market is the world market, and it will soon be against the giants of multinational corporations. It will not be possible to use Xiaomi plus rifles and other aircraft cannons. What kind of equipment do people have? We must also have it. This is absolutely true. However, to achieve this goal, it must be gradual, excessive jumps, and the chance of success is very low. And for different industries, there should be a difference in the progress of different companies. Many companies also need to fill in the scale, cost, and quality development stages, and some have no clear market positioning. At this time, if several units of the world's top most advanced equipment are imported in one step, these advanced machine tools coexist with many old technologies and equipment, even if they can solve some of the hardships of the chucks in the workshop, but they are used in products. The small proportion of value-added effects has little impact on the overall situation and it is difficult to recover investment costs within a reasonable period of time. On the contrary, it lacks the proper connection between the upper and lower processes and the support of various peripheral equipment and environments and it is difficult to function normally. For example, if high-speed milling is imported at a high price, the expensive cutting tool may be required, or the texture of the cutting material and the corresponding heat treatment process are not satisfactory. There is no workpiece pallet and machine presetting, or the quality of the power grid is not so good. The stratified temperature gradient is large and so on. All of the above conditions are undoubtedly resolved, but it is difficult to do so under current conditions. Even if it is done recklessly, because the utilization rate is too low, it is not economical. This is one of the reasons why some imported high-end machine tools are not satisfactory enough for utilization in many domestic enterprises. If the funds are sufficient, the whole line into the high-end machine tool, the problem is not solved? 80 years, a Shenzhen company once imported a full set of the most advanced molding equipment at the time, but due to the management, process and operating personnel configuration can not keep up The people's dilemma ended up paying a lot of money and a long time before the entire line was opened. It is not that we have not received training and many people have gone. However, due to too large a technological gap, the actual situation at home and abroad is far from clear. People think it is a matter of course. We still do not understand clearly, and the foundation of training is not well established. After the equipment is in place, how can it be used to its effectiveness in the actual situation in the country, people will not care about you, they have to go their own way, this is a huge price. Therefore, the domestic technological transformation is only the initial stage of the enterprise. When there is no perceptual knowledge about very advanced equipment and processes, it is better to purchase general or more advanced machine tools. In addition to solving the key processing difficulties in the enterprise, it is relatively easy to train talents and make the technical level of the workshop up one level. Get ready to use the world's best machine tools one day. The Central Government has always stressed that we must introduce practical and advanced technologies and equipment. This reminds us that we should have a clear understanding of the state of our country's productive forces at the development stage. Most high-end machines in the international market are developed for the most advanced industrial countries. In addition, the era of today's market with the same type of machine tool to adapt to the different stages of the global market, educational level and cultural background has passed. However, China’s machine tool market is still not very big. There is still no foreign company that has developed a product specifically for Chinese users. Instead, it wants Chinese users to relocate them and follow their rules. This is clearly unreasonable. It should be changed. Of course, the situation in China is too complicated. It is not an easy task for foreign companies to develop machine tool products specifically for Chinese users. However, it is certain that the current state of the high-end machine tool market in China is bound to change. So Chinese users should wait patiently. When it comes to practical and advanced machine tools, the range of user choices is much wider. In the international market, such machine tools are called standard general-purpose machines. Due to the large market coverage, mass production has considerable advantages in terms of price and performance. Even if it is practically advanced, the difference in performance is very obvious. However, for the sake of commercial profits, some manufacturers intend to extend the performance of their standard machines to high-end machines to expand their application. It is not easy for Chinese users to purchase 1 or 2 sets of advanced machine tools. It is hoped that it can solve more processing problems. In the case of high expectations, it is easy to believe in the above advertising. In fact, since a standard type machine is to become the backbone of machining and has a wide range of applications, it must be composed of a series of models with different characteristics and suitable for different application occasions. Only in this way can there be advantages of production machines. It should be said that the strict definition of performance is a manifestation of the maturity of such machines. That kind of thing seems to be omnipotent. It must be a kind of vigorous pill. It cannot be gullible. Therefore, in the purchase of standard models, there is a need for more nuanced analysis and judgment, and realistically selected performance indicators, which are even more difficult to operate than high-end machines. In procurement, in order to avoid obscure box operations generally adopting the bidding method, a series of menu-type performance indicators are used as levers, which not only reflects the user's intention of purchasing, but also defines the grade of the bidder's products, and finally the lowest in the adopted models. Winning bid. However, in such an operation, the user's report that the winning machine tool is often a medium level, it seems that the performance is more complete, but it has no characteristics. The reason is very clear, the above bidding operation is too simple, with menu-type performance indicators can not completely define the grade of a machine tool, judging whether a certain performance seems easy, but to determine its authenticity, maturity has considerable difficulty. Now that technology monopoly and price monopoly cannot do the same, patent right is just a kind of buffer, so that the leader can take a little initiative in time, and some ways to bypass the patent are. So as long as one company launches a new function, it will take a long time to follow up. Although the names are different, the effectiveness of publicity is similar. Therefore, Li Ge defeated Li Zhi's things from time to time. In the same way, the most important purchasing factors for users: brand, process capability, service life, and service quality are not quantifiable or difficult to assess. In this way, the difficulty of writing bids was greatly increased. It was neither too detailed, but it made bidders discouraged, so that only one or two bids could not be opened; nor could it be too general to allow users to accept unsatisfactory machine tools under the principle of winning the lowest price. In the past few years, users have painstakingly made a fuss about the lines of tenders. For example, the three-point support must be used for the proposed machine tool in procurement. This is indeed a very subtle lever to measure the quality of the machine. Because the final micron accuracy of a three-point supported machine must be guaranteed in the machining assembly, the user does not have to prepare a rigid foundation for it, and may even install it on the floor. The final accuracy of the machine supported by more than five points can be achieved by the high-level technician fine-tuning the anchor screws. The production factory can save time, but the user must prepare a solid foundation. Of course, it is impossible to go upstairs. Moreover, this kind of fine-tuning of the foot screws is not easy to master, and periodic adjustments are really annoying. The creative bids will certainly be seen in the future, indicating that the level of users will continue to increase during the bidding process. However, if the bid price can be used as the bid price, it seems that it can better reflect the user's intentions and needs, make up for some of the deficiencies of the unquantifiable indicators, thus eliminating all kinds of "play mark" bad phenomenon. Nowadays, all kinds of advanced machine tool technology information come through all kinds of channels, but it always contains a transcendence of reality, and it is an ironclad fact that some of the still-exploring technologies are described, and some are still in the developed industrial countries. The behavior of large companies is said to be a universal reality. It is typical to exaggerate the role of high-speed hard milling, saying that electrical machining can be eliminated and that it is a "one off" technology that does not require polishing. However, the operating cost of 800 yuan/h, the use of small-diameter milling cutters and 0.1 mm row-pitch milling on medium and large sized dies, is simply unreasonable in terms of time and cost compared to polishing. It is also impossible to replace electric machining in deep and narrow and micro-cavity machining, let alone machining cemented carbide. What is more, the magical effect of machine automation and intelligent machine-rendering is that the operator can issue a simple command, do not need to operate, and do not monitor and interfere. The machine tool can handle everything, stabilize production and yield, as if the operator has become a bystander. Without special knowledge, just a few hours of on-board training can win any processing problems. The purpose of this kind of propaganda is nothing more than to draw the user's attention to new and expensive new technologies. Of course, there are users who are willing to take risks together with the manufacturers, as long as they have sufficient economic and technological strength. But with our national conditions. At this stage, it is not appropriate to include high-speed machining, highly automated, and intelligent procurement. Many users are attracted by the promotion of high technology and new technologies and lose their direction. In determining the basic performance of machine tools, the relationship between the machine tool and the upper and lower processes is often seldom considered. In fact, any user who purchases a machine tool is looking for the best block for his own production system. The performance of the machine tool should be selected from the overall height. The functions it has can meet the requirements of the production line. Any redundant feature is a waste. We are still in the stage of development and we are in the basic stage. China's labor productivity is low, and human resources are sufficient. The ones we need most now are those with limited automation, good basic performance, and stability and reliability. Moreover, over the years, many institutional reforms have been carried out, and there has been a large gap in equipment upgrades. Under the operation of limited funds, imports can only be a small part of the market. In the 20 years of reform and opening up, China's machine tool industry, which has introduced a large amount of advanced technology and armed forces, has been under the influence of market mechanisms. If the user still can not get rid of the domestic machine trouble, unreliable shadow, you can take the key way to order, pre-sale do process design, after-sales provide the fixture, tool and programming, personnel training, on-site sparring and other services until the acceptance by the drawings Qualified, production beats meet the requirements, users can stabilize production. A paper contract, full service, step by step test, there is no confidence in the manufacturing plant is not afraid to sign such a contract, that is, foreigners also came to sweat. In this way, as long as the indicators are set reasonably and well-operated, users can get maximum support from the manufacturer, and the risk can be minimized. In the current situation, it is better to purchase a practical and standard machine. However, in some industries, such as mold making, its development direction is small and specialized. Only a few key equipments can be used to form the characteristics of a company. It is in an advantageous position in the market competition, and over the years, a large number of talents have been trained. The masters of high-end machine tools have achieved socialization in the technical support of the process linking. As long as the financing is well-founded, they should be the most qualified to lead other machine-building industries to accept high-end machine tools.
