With the improvement of industrial production technology, the traditional machine tool products can not meet the production needs, and the highly numerical control of machine tool products will be the general development trend.
Nowadays, there is an important one in the development concept of the society, namely, saving. The savings here are not just for life but also for industrial production. In the process of industrial development, there will always be plant scenes where new and old equipment work at the same time. After all, the overall industry is constantly improving.
The coexistence of old and new equipment is due to the fact that the old equipment is in good condition and there is still value in continuing to use it; on the other hand, it is because the new production equipment is updated quickly, and in the case where the old equipment still has a large value of use, it is large. The scale of procurement of new equipment is worthless. But how to maximize the use of old equipment? Machine tool products provide a very good example for us.
In the process of saving, we put forward the concept of remanufacturing. Its essence is to make its old condition through the use of products that have a good operating condition, save large value-use products, and integrate and renovate new technologies. The equipment glows with new vitality.
China's current machine tool inventory has reached 8 million units, of which a large number of machine tool products are in a state of need for a lower level of technology, a large number of machine tools retired each year. At the same time, as a type of precision equipment, the machine tool is also very large, and most of the parts have the value of continued use. This also provides a considerable source of supply for the renovation project. In the process of transforming machine tools, traditional machine tool products are increasingly unable to meet the needs of production, and it is urgent to strengthen the level of numerical control. At the same time, the transformation will also increase the numerical control rate of existing machine tools.
The use of old machine tool products for large-scale machine tool remanufacturing and the integration of numerical control technology are significant for the development of a conservation-oriented society. Machine tool transformation will be a conservation-oriented model for the entire industry.
