As a "heavy tool" in modern manufacturing, the processing accuracy and stability of large CNC gantry milling and grinding directly affect product quality and production efficiency. Especially during long-term processing, how to maintain the stability and accuracy of the equipment is a key indicator to measure the performance of a large CNC gantry milling and grinding.The stability of large CNC gantry milling and grinding is first of all due to its sturdy and reliable mechanical structure. The main components such as the bed, columns, and beams made of high-strength cast iron or welded structure are precision machined and aging treated to effectively eliminate internal stress and ensure the rigidity of the equipment under heavy-load cutting. In addition, the application of transmission components such as high-precision guide rails and ball screws, as well as advanced lubrication systems, further reduce the friction and wear of moving parts and ensure the stability of the equipment for long-term operation.Temperature change is an important factor affecting the accuracy of large CNC gantry milling and grinding. In order to reduce the impact of thermal deformation on processing accuracy, large CNC gantry milling and grinding usually adopts a thermally symmetrical structure design and is equipped with a temperature compensation system. For example, temperature sensors are installed in key parts such as the bed and columns to monitor temperature changes in real time, and the processing parameters are dynamically adjusted through the control system to compensate for the errors caused by thermal deformation.In addition to hardware guarantees, advanced control systems are also the key to maintaining stability and accuracy for large CNC gantry milling and grinding. The use of high-performance CNC systems can achieve precise control of the processing process and compensate for various errors in real time. For example, through detection equipment such as laser interferometers, the geometric accuracy and positioning accuracy of machine tools are regularly detected and compensated to ensure that the equipment is always in the best working condition.In addition, large CNC gantry milling and grinding is also equipped with a complete vibration monitoring and fault diagnosis system. Vibration sensors installed in key parts can monitor the vibration of the equipment in real time, and alarm in time when abnormalities occur to avoid equipment damage and processing accidents. At the same time, through the analysis of equipment operation data, potential faults can be predicted, and maintenance can be carried out in advance to extend the service life of the equipment.The skill level and operating specifications of the operator also have an important impact on the stability and accuracy of large CNC gantry milling and grinding. Therefore, it is necessary to provide professional training for the operators so that they can master the operating skills and maintenance knowledge of the equipment and operate strictly in accordance with the operating procedures to avoid the influence of human factors on the accuracy of the equipment.In short, the stability and accuracy of large CNC gantry milling and grinding is a systematic project, which requires comprehensive consideration from multiple aspects such as mechanical structure, temperature control, control system, vibration monitoring, and personnel operation. Only through careful design, manufacturing, installation, commissioning and maintenance can we ensure that large CNC gantry milling and grinding always maintains excellent performance during long-term processing and provide strong support for the development of the manufacturing industry.
