CNC machine tools are important equipment in modern manufacturing, and the workbench is one of the core components of CNC machine tools. The stable operation of the workbench is essential for machining accuracy and quality, so maintaining the workbench is one of the common maintenance tasks for CNC machine tools. Now let’s talk about common sense about the maintenance of CNC machine tool workbench.
First of all, before starting processing every day, check the workbench, including whether the screws of the bed, guide rails, workbench and nuts are loose, whether the lubrication system of the workbench is normal, and whether the noise when the machine tool automatically travels back and forth is normal, etc. If any abnormality is discovered, it must be dealt with promptly.
Secondly, keep the workbench dry and clean, especially when the machine tool adjustment is small and the processing accuracy is high. Dust, dirt, chips, etc. on the surface of the workbench may affect the accuracy and cause the processed products to be unqualified. Add a special protective cover to the working surface of the machine tool to reduce dust erosion on the workbench while ensuring the stability of processing accuracy.
Third, pay attention to the lubrication of the workbench. The grease or oil parts on the machine tool guide rails are often damaged during operation. They must be replaced or refueled every once in a while. Dust and debris must be cleaned before refueling in the lubricating parts, and the grease must be added according to the specified points and amounts. Apply lubricating oil or grease, pay special attention to the amount of lubricating oil or grease added, and generally do not exceed the specified yellow line marked area. The grease of CNC machine tools with high machine tool stability and high manufacturing precision requirements must be added in strict accordance with regulations.
Fourth, pay attention to the cooling system of the workbench. During the machining process, it is often necessary to cool the workpiece and tool to avoid the occurrence of high temperatures, which requires daily inspection of the cooling system of the machine tool. The coolant should be maintained within a suitable temperature range, and new liquid should be added continuously to ensure stable operation of the workbench.
Finally, there are considerations regarding machine tool protection. The machine tool cannot be overloaded, and the machine tool needs to be inspected regularly, including keys, bearings, guide rails, lubrication systems and other parts, so that problems can be dealt with promptly.
In the process of maintaining the workbench, a long-term maintenance plan and specific safety operating specifications are required to ensure the normal operation of the machine tool, improve the accuracy and quality of processed products, and extend the service life of the machine tool.
