An empirical analysis of improving the reliability level of CNC machine tools
Most of our manufacturing industries and enterprises of production and processing equipment, the vast large numbers is the traditional tools, and more than half is enlistment age in more than 10 years old machine. Even most of CNC machine tools, CNC machine tools, production equipment and technology, backward and old. Products processing equipment used by the widespread poor quality, less variety, low grade, high cost, delivery period long, resulting in international and domestic markets, lack of competitiveness, and a direct impact on a business of product, market, benefit, affect the enterprise's survival and development. So it is necessary to improve the rate of CNC machine tools.
1 CNC machine tools and production lines of the transformation industry market
The transformation of CNC machine tool Market
Our country machine total more than 380 million units, and the total number of CNC machine tool only 11.34 million units, namely China CNC rate of less than 3%. Over the past 10 years, China's annual output of numerically controlled machine tools about 0.6 ~ 0.8 million units, annual production value of about 18 billion yuan. The annual output rate of CNC machine tools for 6% years, the output value of NC rate was 12%. But the economic type CNC machine tools CNC machine tools accounted for more than 80%, not much advanced machine tool automatic machine etc.. China Machine Tool easements for more than 10 years accounted for more than 60%; in the 10 years following the machine tool, automatic / semi-automatic machine tool for less than 20%, FMC / FMS and other automated production lines a handful more. Visible most of our manufacturing industries and enterprises of production and processing equipment, the vast large numbers is the traditional tools, and more than half is enlistment age in more than 10 years old machine. Even most of CNC machine tools, CNC machine tools, production equipment and technology, backward and old. Products processing equipment used by the widespread poor quality, less variety, low grade, high cost, delivery period long, resulting in international and domestic markets, lack of competitiveness, and a direct impact on a business of product, market, benefit, affect the enterprise's survival and development. So it is necessary to improve the rate of CNC machine tools.
According to experts predict that by 2000, China's CNC machine tool consumption of up to. These needs hand through the purchase of new equipment to meet. On the other hand, if make full use of our existing stock of assets, after renovation of equipment substitution and reduction in the purchase of new equipment, can play a multiplier effect. To estimate the demand for the yuan, even if 10% of the demand through the equipment to achieve the regeneration of the transformation, there are 2 billion 400 million yuan per year of the market.
Import equipment and production line of the numerical control of the transformation of the market
Since China's reform and opening up, a lot of enterprises to introduce technology, equipment and production lines from abroad to carry out technical transformation. According to incomplete statistics, from 1979 to 1988 10 years, the introduction of technical transformation project on the country there are 18446, about $.
Most of these projects play a due role in the economic construction of our country. However, some imported projects for various reasons, equipment or production lines can not be normal operation, or even paralysis, so that the efficiency of the enterprise is affected, and seriously make the enterprise into a difficult situation. In order to make full use of these equipments and production lines, we have conducted a survey on the part of the introduction of 10 years, and the technical transformation project related to the machinery industry. We understand that some of the equipment, production lines imported from abroad, the digestion and absorption of some bad, spare parts, improper maintenance, poor operating results; some introduction only pay attention to the introduction of equipment, apparatus, production lines, ignore software, technology and management, resulting in project is not complete, and potential equipment can not play; some can't even start running, did not play its due role; some production line of products sell very well, but because of equipment failure can not reach the standard; because some high energy consumption, low rate of qualified products incur losses; some have introduced a longer time and need to update technology. All sorts of reasons make some equipment not only did not create wealth, but consumption of wealth.
These can not use the equipment, the production line is a burden, but also a lot of the stock of assets, fixed is the wealth. As long as the main technical difficulties to identify, solve the key technical problems of the neck of the card, you can minimize the amount of investment to revitalize the largest stock of assets, to maximize the economic benefits and social benefits. This is also a great transformation of the market.
2 NC transformation of the content, principles and technology
The rise of foreign trade reform
In the United States, Japan, Germany and other developed countries in the machine tool industry downturn today, but their transformation of machine tool industry as a new economic growth, business vitality, in the golden age. The progress of machine and technology, machine tools transformation is a eternal topic. China's machine tool industry transformation, but also from old industries to enter the digital technology - based new industries. In the United States, Japan, Germany, and has a broad market with CNC technology to transform machine tools and production lines formed anumerically controlled machine tools and production lines of the new industries. In the United States, machine tool industry calledmachine regeneration industry. Engaged in renewable industry in the famous companies: Bertsche engineering company ayton machine tool company, DevliegBullavd services group, US equipment company. The United States company has run the company in China. In Japan, the machine tool industry transformation as modifications of machine tool industry. In refitting industry famous company: Okuma engineering group, post 3 machinery company, Chiyoda engineering company, Nozaki engineering company, shore field engineering company, Yamamoto engineering company. The content of null CNC machine tools and production lines of the transformation of the NC transformation of the main contents are as follows:
One is to restore the original function of machine tool, fault diagnosis and production line
