Daily maintenance of machining center equipment

After each vertical machining center has been running for a certain period of time, some components will inevitably suffer from some damage or failure. In order to reduce the abnormal wear of the machine tool, prolong the service life of the components as much as possible, and effectively avoid sudden failure, especially the occurrence of malignant accidents. The machining center equipment company must do a good job in the daily maintenance of the vertical machining center to keep the vertical machining center equipment in good working condition and reduce the aging process of the equipment, timely detection and elimination of hidden trouble, so as to ensure safe operation. The safe operation and maintenance of vertical machining centers are necessary, which is one of the key factors in the correct use of CNC equipment.

1. The use environment of the vertical machining center, in order to improve the service life of the numerical control equipment, it is generally necessary to avoid direct sunlight and other heat radiation, and to avoid environmental humidity, excessive dust or corrosive gases. It is also necessary to keep precision numerical control equipment away from large vibration equipment, 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, numerical control equipment generally needs to use dedicated line for power supply (e.g. separate supply for numerical control machine tools from low-voltage distribution room) * * * good addition of voltage stabilizing device, etc., which can reduce the influence 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 shift system, which is the main content of the use and management of CNC equipment. The development and compliance of operating procedures is one of the important measures to ensure the safe operation of CNC machine tools. Practice has proved that most failures can be avoided by following the operating procedures.

4. Vertical machining center should not be sealed for a long time. After purchasing vertical machining center, it should be used in time. Especially in the first year of use, most of the weak links that are prone to failure can be exposed, which can be excluded during the warranty period of the manufacturer. In the process, minimize the opening and closing of the spindle of the CNC machine tool, which can reduce the wear of the clutch, gear and other devices. If there is no processing task for a long time, the numerical control machine tool should also be powered on regularly. The best thing is to power on 1-2 times a week and run dry for about 1 hour each time. In this way, the heat generation of the machine tool can be used to reduce the humidity in the machine and avoid moisture damage to electronic components. At the same time, it can also timely find out whether there is a battery power shortage alarm to prevent the loss of set parameters in the system.

5., strictly abide by the operating procedures and daily maintenance system, vertical machining center operators should strictly abide by the operating procedures and daily maintenance system, the technical level of the operator is an important factor affecting the frequency of equipment failure. When the machine tool fails, the operator should pay attention to keeping the scene and truthfully explain the situation when the failure occurs 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 inside of the numerical control device. There are usually oil mist, dust and even metal powder in the air of the processing workshop. Once they fall on the circuit board or electronic devices in the numerical control system, it is easy to cause the insulation resistance between components to drop, Even lead to damage to components and circuit boards.

7. To prevent the system from overheating, check whether each cooling fan on the CNC cabinet is working properly. Should be regularly every six months or every quarter to check the air duct filter is clogged, if the filter net dust accumulation is too much, should be cleaned in time, otherwise it will cause the temperature inside the numerical control cabinet is too high.
