Since the beginning of the financial crisis in 2008, the magnitude of the appreciation of the renminbi against the appreciation of foreign currencies has continued to increase. The prices of domestic machine tools have continued to climb, and the price of imported machine tools has become even more competitive. Imported machine tools on the technical level, domestic machine tools are still far behind. Although it is a used machine tool, it is difficult to import domestically. Sometimes the price of second-hand imported machine tools and the price of new domestic machine tools are still very advantageous. Let's discuss the appearance, precision, accuracy retention, structural stability, and parts quality of second-hand machine tools.
Design -----Imported used machine tools give people the overall feeling from the appearance, the smoothness of the lines, and the humanized design of the operation panel are quite different from the domestic ones. It is no exaggeration to say that if domestically-made used machine tools and imported second-hand machine tools are put together, you can recognize them at a glance.
Accuracy ----- For example, a certain brand of machine tool in Japan has a 0.005mm repeatability of positioning accuracy of 0.003mm, and domestically produced products are in a few channels, ie several hundredths of a millimeter.
Retention ----- In general, the private sector will not stop the machine for 24 hours, which is obviously a test for machine tools. Xiao Bian once heard of such customers, because domestic prices are cheap, feel that domestic will not be too bad, to buy a domestic brand of rice machine, use one year X axis to play the full accuracy of more than 20, Can only use it to do rough machining, and can not say that domestic machine tools do not have a little advantage, but it can not be ignored because of the cheap.
Structural stability ----- is mainly the stability of the bed castings. People in the industry all know that there is a big gap between the casting process in our country and other developing countries such as Japan.
Component Quality ----- Japanese machine tool production uses parts purchased globally to optimize product quality and minimize costs. Domestic companies, however, differ in the fact that almost all parts and components have to be produced by themselves and they must be forced to purchase outside the country. Most of the parts purchased are mainly made in China.
The mutual matching of parts and components ----- The machine tool has a high-quality configuration does not necessarily mean that it is a high-quality machine tool, the domestic machine tool manufacturers do not optimize the combination of high-quality components, resulting in poor mutual matching, not From time to time there are various problems.
At present, there is a big gap between domestic machine tools and imported machine tools, and the development of domestic machine tools still has great room for improvement. Domestic machine tool manufacturers continue to improve product quality is the first choice for sustainable development.
