The rise of foreign transformation industry In the United States, Japan and Germany and other developed countries, their machine tool transformation as a new economic growth industry, full of business, is in the golden age. Due to the continuous improvement of machine tools and technology, machine tool transformation is an "eternal" topic. China's machine tool industry, but also from the old industry into the CNC technology-based new industry. In the United States, Japan and Germany, with CNC technology to transform machine tools and production lines has a vast market, CNC machine tools and production lines have formed a new industry transformation. In the United States, the machine-building industry is called the Remanufacturing industry. Renowned companies in the recycling industry include: Bertsche Engineering, ayton machine tool company, Devlieg-Bullavd service group, US equipment companies. US Depot Company has started a business in China. In Japan, the machine tool industry is called the Retrofitting industry. Well-known companies engaged in the conversion industry: Ohashi Engineering Group, Gang three machinery companies, Chiyoda Works Corporation, Nozaki Engineering Company, Hamada Engineering Company, Yamamoto Engineering Company. The contents of NC transformation: The main contents of CNC machine and production line transformation are the following: (A) is to restore the original function, the machine tool, the production line fault diagnosis and recovery; (B) is NC, in the ordinary (3) is refurbished, in order to improve the accuracy, efficiency and degree of automation, the mechanical and electrical parts of the renovation, the mechanical part of the re-assembly and processing, Restore the original precision; do not meet the production requirements of the CNC system with the latest CNC update; (D) is a technology update or technological innovation, to improve performance or grade, or in order to use new technology, new technology, based on the original Large-scale technological innovation or technological innovation, a substantial increase in level and grade of the renovation. (E) the advantages and disadvantages of numerical control transformation: 1, reduce investment, delivery time is short. 2, compared with the purchase of new machines, the general can save 60% to 80% of the cost, low transformation costs. Especially large, special machine is particularly obvious. 3, the transformation of the general large-scale machine tools, only spent the purchase of new machine costs 1/3, delivery time is short. However, in some special cases, such as high-speed spindle and automatic pallet changer manufacturing and installation are too laborious and costly, the cost of retrofitting is often increased by two to three times. Compared with the purchase of a new machine, the investment can only be saved by about 50%. 4, stable and reliable mechanical properties, the structure is limited by the use of the bed, columns and other basic components are heavy and solid casting components, rather than the kind of welding components, the modified machine performance, good quality, can be used as new equipment Continue to use for many years. 5, but subject to the original mechanical structure, should not make a breakthrough transformation. Familiar with the equipment, easy to operate and repair When buying new equipment, do not understand the new equipment.
