What does the maintenance of CNC machine tools include?
Moderate maintenance is to make better use of the effectiveness of the control machine tool, reduce the occurrence of common faults, and increase the average value of the machine tool. So what does the maintenance of CNC machine tools include?
Maintenance of CNC machine tools:
Do a good job of cleaning and lubricating the surface of each slide rail. Machine tools with automatic lubrication systems should check and clean the automatic lubrication systems in time. Most CNC machine tools and equipment use rails to achieve fitness movements in a rapid cycle system. The rollers in the track are composed of more than 100 high-precision steel balls, so the screw of the CNC machine tool must not lack oil. In addition, the ball screw and the nut of the X, Y, and Z axes of the machine tool are also composed of bead strings, and the circuit of the CNC machine tool cannot be less oily.
Check the automatic lubrication system of the spindle bearing housing. All normal bedroom bed boxes are usually completed by gears and bearings on the shaft. In order to keep the oil passage unblocked, the new mechanical equipment should be disassembled and replaced with grease in time. If the gear of the new CNC machining center is damaged, it will cause iron friction to prevent dirty things from entering the bearing and causing damage.
Check whether the cooling fan in the electric control box of the computer numerical control machine tool is working normally. Whether the air duct filter blocks the sewage pump to remove the attached dust. For CNC machine tools, the electrical control system of the machine tool is very important to check whether there is dust in the electrical control box. Whether the electrical components are damaged, whether the fans in the distribution box and the central air conditioner are in normal operation.
Pay attention to check the refrigeration system. Check the liquid level aspect ratio and add oil or water immediately. When the oil and water are dirty, they should be replaced and cleaned. Refrigerant cooling is essential for CNC machine tools. Over time, the water has iron cuts and frozen liquid precipitates. This stain should be removed immediately to prevent clogging of centrifugal pumps and water pipes.
Pay attention to check the looseness of the slide rail inserts and adjust the clearance. After the CNC machine tool has been used for a period of time, due to normal damage, in order to ensure the accuracy of the machine tool, the gap between the image strip and the Fritillaria should be adjusted frequently.
In addition, when the CNC machine tool is not needed for a long time, the machine tool should be kept according to regulations. The inside and outside of the CNC machine tool should be cleaned, covered with a protective cover, and disconnected from the switching power supply. When the CNC system is idle for a long time, it must be inserted into the system frequently, especially in the rainy weather when the air relative humidity is high.
