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

The transformation of ordinary machine tools to CNC is mainly to creatively design the structure of the original machine tool, so that the machine tool can reach a relatively ideal state. CNC lathe is a typical representative of electromechanical integration, and its mechanical structure has many similarities with ordinary machine tools. However, the modern CNC machine tool is not simply equipped with a CNC system on the traditional machine tool, nor is it only partially improved on the basis of the traditional machine tool (those restricted by funds and other conditions, and the conversion of the traditional machine tool into the recommended CNC machine tool is another matter). There are some weaknesses in traditional machine tools, such as insufficient rigidity, poor vibration resistance, large thermal deformation, large friction resistance of sliding surface and clearance between transmission elements, which are difficult to meet the requirements of CNC machine tools for machining accuracy, surface quality, productivity and service life. The modern CNC technology, especially the machining center, has undergone great changes in the structure of its supporting parts, main transmission system, feed transmission system, tool system, auxiliary functions and other components, as well as the overall layout and external modeling, and has formed the unique mechanical structure of the CNC machine tool. Therefore, in the process of NC transformation of ordinary machine tools, we should consider various conditions to make the performance indicators of ordinary machine tools as close as possible to those of CNC machine tools.

The significance of transforming ordinary machine tools into CNC:

1. Saving money: compared with the purchase of new machine tools, the NC transformation of machine tools can generally save about 60% of the cost, especially for large and special equipment. Generally, the transformation 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 transformed and upgraded, it only costs 60% of the cost of purchasing a new machine tool, and the existing foundation can be used.

2. Stable and reliable performance: because the original machine tool's basic parts have been aged for a long time, they will hardly produce stress deformation and affect the accuracy.

3. Improve production efficiency: the automatic efficiency of machining can be realized after the numerical control transformation of the machine tool, which is 3 to 5 times higher than that of the traditional machine tool. For complex parts, the higher the difficulty, the higher the efficiency.

With the continuous development of China's manufacturing industry and the continuous improvement of the level of machining, more and more CNC machine tools have replaced the traditional machine tools. However, due to the high price of CNC lathes, ordinary enterprises cannot afford it. Therefore, it is a relatively reasonable way to carry out CNC transformation of ordinary lathes, which can effectively improve the automatic processing ability of the machine tool and improve the processing effect on the basis of cost control. Therefore, at this stage, it is of great practical significance to strengthen the research on the transformation of ordinary machine tools into numerical control. It can more comprehensively grasp the relevant technologies of the transformation of ordinary lathe into numerical control, improve the effect of the transformation of numerical control, thus improving the working efficiency of lathe, better play the potential value of old equipment, and improve the economic benefits of mechanical processing enterprises.
