What is the significance of transforming ordinary machine tools into CNC?

The transformation of ordinary machine tools into CNC mainly involves creative design of the original machine tool structure to achieve a relatively ideal state of the machine tool. CNC lathe is a typical representative of electromechanical integration, and its mechanical structure has many similarities with ordinary machine tools. However, modern CNC machines are not simply equipped with a CNC system for traditional machines, nor are they based on traditional machines and only partially improved (those that are limited by funding and other conditions, and those that convert traditional machines into recommended CNC machines are another matter). Traditional machine tools have some weaknesses, such as insufficient rigidity, poor vibration resistance, large thermal deformation, large frictional resistance of sliding surfaces, and gaps between transmission components, which are difficult to meet the requirements of CNC machine tools for processing accuracy, surface quality, productivity, and service life. Modern CNC technology, especially machining centers, has undergone significant changes in the structure of their supporting components, main transmission system, feed transmission system, tool system, auxiliary functions, and other components, as well as in the overall layout and external modeling, and has formed the unique mechanical structure of CNC machine tools. Therefore, in the process of numerical control transformation of ordinary machine tools, we should consider various situations to make the performance indicators of ordinary machine tools as close as possible to those of numerical control machines.

The significance of transforming ordinary machine tools into CNC:

1. Saving funds: Compared to purchasing new machine tools, NC transformation of machine tools can generally save about 60% of the cost, especially for large and special equipment. Generally, the renovation of large machine tools only costs 1/3 of the purchase cost of new machine tools. Even if the structure of the original machine tool is completely upgraded, it only costs 60% of the cost of purchasing a new machine tool, and the existing foundation can be utilized.

2. Stable and reliable performance: Due to the long-term aging of the original machine tool's basic components, there is almost no stress deformation that affects the accuracy.

3. Improve production efficiency: After numerical control transformation, the machine tool can achieve automatic processing efficiency that is 3 to 5 times higher than traditional machine tools. For complex parts, the higher the difficulty, the greater the efficiency.

With the continuous development of China's manufacturing industry, the level of machining continues to improve, and more and more CNC machine tools have replaced traditional machine tools. However, due to the high price of CNC lathes, ordinary enterprises cannot afford it. Therefore, CNC transformation of ordinary lathes has become a relatively reasonable way to effectively improve the automatic processing ability of the machine tool and improve the processing effect on the basis of controlling costs. Therefore, at this stage, strengthening the research on the transformation of ordinary machine tools into numerical control has important practical significance, enabling a more comprehensive grasp of the relevant technologies for the transformation of ordinary lathes into numerical control, improving the effectiveness of the transformation, thereby improving the working efficiency of lathes, better playing the potential value of old equipment, and improving the economic benefits of mechanical processing enterprises.
