Keeping the machine tool clean is the first step to extend the life of the equipment. After using the machine tool every day, the operator should promptly remove iron filings, oil stains and dust on the surface of the machine tool, especially key parts such as guide rails, lead screws, and spindles. At the same time, the lubrication system of the machine tool should also be regularly checked and lubricated to ensure the smooth operation of moving parts such as guide rails and bearings to prevent wear and overheating. It is recommended to use the special lubricating oil recommended by the manufacturer and replace it periodically.
2. Standardize operation to prevent misuse
The correct operation of CNC machine tools is related to whether the equipment can operate stably for a long time. Operators must receive professional training and be familiar with the operating procedures and safety regulations of the equipment. Before use, be sure to preheat the machine, especially in low temperature environments in winter, and pay attention to allowing the lubricating oil to flow fully before starting processing. In addition, irregular behaviors such as overload processing and forced power off are prohibited, as these operations may cause serious damage to the electrical system and mechanical structure.
3. Keep the electrical system stable
The control system of CNC machine tools relies on precision electrical components and has high requirements for power supply stability. To ensure the safety of the electrical system, a voltage stabilizer or UPS power supply should be equipped to avoid program loss or system failure due to unstable voltage or sudden power outage. In addition, regularly check whether there is dust accumulation in the electrical cabinet and whether the connecting wires are loose, and keep the electrical components in good contact, which can effectively avoid failures.
4. Pay attention to the cooling system and temperature control
A large amount of heat will be generated during the processing process. Especially during high-speed cutting, if the cooling system does not operate well, it is easy to cause deformation of the spindle, tool and workpiece. Therefore, the level and concentration of the coolant must be checked regularly, kept clean and replaced in time. Pumps, nozzles and other components in the cooling system must also be maintained regularly to prevent blockage. For some high-precision processing, you can also consider configuring a constant temperature environment to reduce the impact of temperature differences on machine tool accuracy.
5. Regularly check accuracy and adjust equipment
After a period of use, the CNC machine tool may lose accuracy due to mechanical wear or external forces. Therefore, the geometric accuracy, positioning accuracy and repeated positioning accuracy of the equipment should be checked regularly to detect deviations and correct them in time. Problems such as guide rail clearance, loose screws, and spindle runout should also be checked and adjusted regularly. Keeping the equipment in a high-precision state is the key to ensuring long-term stable operation.
The service life of CNC machine tools depends not only on the quality of the equipment itself, but also on the use and maintenance of the users. Through scientific and standardized operation, regular maintenance, precision calibration and environmental management, the life of the machine tools can be effectively extended, the processing efficiency can be improved and the operating costs can be reduced. Only by taking "equipment maintenance" as an important part of daily management can the long-term value of CNC machine tools be truly brought into play.
