In the development of the world economy, the machinery manufacturing industry plays an important role as a basic industry. To this end, economists and entrepreneurs in various countries are constantly exploring the development strategies of various advanced manufacturing technologies and manufacturing industries under the new situation. The machine tool manufacturing industry, which is the core of manufacturing, is the cornerstone of the pillar and is indispensable for any industry.
First, the social and economic foundation of production and development
(1) China's existing tens of thousands of old and backward machine tools are the realistic basis for the machine tool overhaul and numerical control transformation industry. China is a developing country. Due to the long-term incompatibility of its own mechanism, its economic strength is too low. Technology is backward and equipment is outdated, which greatly restricts the development of the national economy. In order to change the backwardness of China's machinery manufacturing industry as soon as possible, we have actively introduced the world's advanced technology and equipment while developing the national machine tool manufacturing industry for more than 20 years. On the one hand, in cooperation with the world's advanced machine tool manufacturers, we continue to produce all kinds of machine tools with world-class levels; on the other hand, we directly purchase a large number of various types of machine tools. All of this has played a huge role in the rapid development of China's national economy.
However, the machine tool is used for a long period of time or even overloaded, and at the same time it lacks serious repair and maintenance, causing serious wear and loss of precision of the machine tool. Some machine tools are left unused for a long time due to changes in the structure of the company personnel and products, or due to insufficient technical strength. When it is needed, it is found that it has been rusted, and the electronic control system cannot be started. Due to the needs of new product manufacturing, the original machine tool performance can no longer meet the requirements of use, and it is urgent to update and upgrade; due to the rapid development of the world's computer and network technology, CNC is caused. The product update of the system and drive system factory is accelerated, and the original products are discontinued prematurely, which brings certain difficulties to the replacement and maintenance of spare parts. Moreover, the service life of the numerical control system is generally 5 to 10 years, and most of the machine tools in China are in service. These many factors require overhaul and numerical control upgrades of machine tools.
(2) Newly-advanced second-hand machine tools have become the catalyst for machine tool overhaul and numerical control transformation industry. Since the reform and opening up, many companies have introduced a large number of old machine tools that have been eliminated from abroad. Although some of them can still meet the requirements for use, most of them lack experience. Factors such as technology, data and spare parts have created an embarrassing situation in which they are cheap to buy but cannot continue to function. Among them, there are many old machine tools and production lines that were introduced for use after the transformation. Most of the used machine tools here can be used as long as they have appropriate capital investment.
(3) Significant economic benefits are the development momentum of machine tool overhaul and CNC transformation industry. For machine tool owners, the same effect can be obtained by simply purchasing less than 30% of the cost of the same new machine. According to the international industry records, even if the structural performance of the original machine tool is completely upgraded and upgraded, it only costs about 60% of the purchase of a new machine tool.
For the major companies in the machine tool modification, this not only creates huge social and economic benefits for their service companies, but also the fundamental driving force for their own survival and development.
(4) The advantages of machine tool overhaul and numerical control transformation are the favorable conditions for the survival and development of the industry. Compared with the purchase of new machine tools, the overhaul, renovation and upgrade of old machine tools have the following advantages:
1 delivery time is short. Especially the advantages of large machine tools and special special machines are more obvious.
2 performance is more stable. After long-term aging, the basic parts will hardly cause stress deformation and affect the accuracy; each functional component will wear out for a long time. Functional stability and reliability.
3 design risk is small. The technical and program risks brought about by the new machine tool design are almost non-existent in the big modification.
4 can more fully reflect the wishes of the users. Users and maintenance personnel can propose improvements (including additions and changes) in machine performance, operation and maintenance in accordance with actual needs and long-term use of machine tools. They have the right to choose mechanical parts, CNC systems and other electrical equipment. Specifications, models, performance, etc.
5 is more conducive to use and maintenance. Since users and maintenance personnel can not only participate directly in the formulation of the transformation plan, but also participate in the whole process of transformation, they can directly obtain various technical information, and more deeply grasp the structure and performance characteristics of the machine tool, thereby enhancing the initiative of use and maintenance.
6 Get the latest and more practical spare parts faster.
7 save a lot of investment.
8 reduce investment risks.
