The accuracy of a CNC gantry milling machine refers to the original accuracy of the machine without external loads, which is usually represented by its opposite value and deviates from the ideal state. The smaller the error, the higher the accuracy; On the contrary, the larger the error, the lower the accuracy. The use of machine tools has become very common nowadays, but in recent years, a series of high-precision machine tools, such as the newly introduced CNC gantry milling machine, have been overlooked in daily maintenance work. Some malfunctions of CNC gantry milling machines can be avoided through maintenance. Develop rules and regulations for daily maintenance of CNC gantry milling machines when using them. Only in this way can the accuracy and lifespan of the machine tool be guaranteed to be longer, creating good time efficiency!

The testing operation of the CNC gantry milling machine also requires checking the accuracy. The specific methods are as follows:

1. Start the CNC gantry milling machine to move the workbench, check if its movement direction is consistent with the rotation direction of the motor, and observe the lubrication of the workbench guide rail. If the lubrication is not good, please add lubricant in a timely manner.

2. Test the lifting motion of the crossbeam: before starting. Adjust the gap between each sliding guide surface. Then loosen the screws to test the lifting motion.

3. Test feed motion: Before testing. Adjust the gap between the sliding guide surfaces of the tool holder and check the sealing of each sliding surface by manually shaking the tool holder; Then inject oil into each sliding surface to start the manipulation test before the test. Adjust the gear or handle connected to the fuel supply to the neutral position; Then observe whether the feed mechanism operates normally, check whether there are obstacles, and adjust each tool rest. Perform electric feed testing in both horizontal and vertical feed states.

After the trial operation is completed. Check accuracy and make adjustments item by item based on the qualification certificate. If necessary, the T-shaped groove on the workbench can be improved.
