Daily maintenance of machining center

After each vertical machining center has been running for a certain period of time, some components will inevitably be damaged or malfunction. In order to reduce the abnormal wear of the machine tool, extend the service life of the components as much as possible, and effectively avoid sudden failures, especially vicious accidents; do a good job of daily maintenance of the vertical machining center to keep the vertical machining center equipment in good working condition, reduce the aging process of the equipment, and promptly discover and eliminate potential faults, so as to ensure safe operation. Safe operation and maintenance of the vertical machining center is one of the key factors for the correct use of CNC equipment

1. The use environment of the vertical machining center company. In order to increase the service life of CNC equipment, it is generally necessary to avoid direct sunlight and other heat radiation, and avoid humid environment, excessive dust or corrosive gas. Precision CNC equipment should also be kept away from equipment with large vibrations, such as punching machines, forging equipment, etc.
2. Good power supply guarantee. In order to avoid the influence of large power supply fluctuation (greater than ±10%) and possible instantaneous interference signals, CNC equipment generally uses dedicated power supply (such as a separate line from the low-voltage distribution room for CNC machine tools). It is best to add a voltage stabilizing device, etc., which can reduce the impact of power supply quality and electrical interference.
3. Formulate effective operating procedures. In the use and management of CNC machine tools, a series of practical and effective operating procedures should be formulated. For example, lubrication, maintenance, reasonable use and standardized handover system are the main contents of the use and management of CNC equipment by enterprises. Formulating and complying with operating procedures is one of the important measures to ensure the safe operation of CNC machine tools. Practice has proved that most faults can be reduced and avoided by complying with operating procedures.
4. Vertical machining centers should not be sealed for a long time. After purchasing vertical machining centers, they should be used in time, especially one year after they are put into use. Most of the weak links that are prone to failure can be exposed, so that they can be eliminated within the manufacturer’s warranty period. During processing, try to minimize the opening and closing of the CNC machine tool spindle, which can reduce the wear of clutches, gears and other components. If there is no processing task for a long time, the CNC machine tool should also be powered on regularly. It is best to power it on 1 to 2 times a week, and run it idle for about 1 hour each time. In this way, the heat generated by the machine tool itself can be used to reduce the humidity in the machine and prevent the electronic components from being damaged by moisture. At the same time, it can also promptly detect whether there is an alarm for insufficient battery power to prevent the loss of set parameters in the system.
5. Strictly abide by the operating procedures and daily maintenance system. The operators of the vertical machining center must strictly abide by the operating procedures and daily maintenance system. The technical level and quality of the operators are important factors affecting the frequency of equipment failures. When the machine tool fails, the operator should pay attention to retaining the scene and truthfully explain the situation when the failure occurred to the maintenance personnel, so as to facilitate the analysis and diagnosis of the cause of the failure and eliminate it in time. ?
6. Prevent dust and dirt from entering the CNC device. The air in the processing workshop usually contains oil mist, dust and even metal powder. Once they fall on the circuit boards or electronic devices in the CNC system, it is easy to cause the insulation resistance between components to decrease, and even cause damage to components and circuit boards.
7. To prevent the system from overheating, you should check whether the cooling fans on the CNC cabinet are working properly. Check the air duct filter for blockage every six months or every quarter. If there is too much dust on the filter net, clean it in time, otherwise it will cause the temperature in the CNC cabinet to be too high.
