Abnormal noises in the movement of the machine tool guiderail will not only affect the normal operation of the machine tool, but may also indicate potential failures. It is crucial to quickly locate and solve this problem.
The first is the location problem. When you hear abnormal noises in the guide rail, the first step is to observe the operating status of the machine tool. Carefully check the moving parts of the guide rail to see if there are obvious foreign objects entering. For example, metal debris, chips or other impurities may get stuck between the guide rail and the slider, causing abnormal friction and noise. At the same time, check the lubrication of the guide rail. If the lubricant is insufficient or the lubricant has deteriorated, the dry friction or semi-dry friction between the guide rails will increase, resulting in abnormal noises. In addition, pay attention to the installation of the guide rails and check whether the guide rails show signs of looseness or deformation. Because of improper installation, if the guide rails are not installed to the required parallelism and straightness, additional stress will be generated during movement, causing abnormal noises.
After determining the problem, it is necessary to solve it. If the abnormal noise is caused by foreign matter, it is necessary to stop the machine immediately for cleaning. Foreign matter can be removed with a clean brush or compressed air. For lubrication problems, it is necessary to replenish or replace qualified lubricants in time. When replenishing lubricating oil, make sure that the lubricating oil can be evenly distributed on the surface of the guide rail. Generally speaking, the lubricating oil can be slowly injected into the oil tank of the guide rail through a special oiling device.
If the abnormal noise is caused by the guide rail installation problem, it is necessary to readjust the installation accuracy of the guide rail. For small machine tool guiderails, adjustment shims can be used to correct the parallelism and straightness errors of the guide rails. For large machine tool guiderails, professional measuring tools and adjustment equipment, such as laser interferometers and high-precision jacks, may be required to ensure the accuracy of the guide rail installation.
Finally, after solving the abnormal noise problem, the machine tool guiderail needs to be tested. Let the machine tool run at different operating speeds and load conditions to check whether the abnormal noise is completely eliminated. In addition, establish a mechanism for regular inspection and maintenance to prevent the abnormal noise problem from recurring and ensure that the machine tool guiderail can work stably for a long time.
