Spindle is one of the core parts of CNC machine tool with inclined bed, and its normal operation is very important to the performance and machining quality of machine tool. However, in the course of use, spindle failure will inevitably occur. This paper will focus on the fault analysis and maintenance of the spindle of CNC machine tool with inclined bed.

First, let's look at the possible causes of spindle failure. The first could be a lubrication problem. Due to long-term use or lubricating oil pollution and other reasons, the lubrication system may be abnormal, resulting in increased spindle friction or interference phenomenon. In addition, failure can also occur if parts such as bearings or seals that are badly worn are not replaced in time. The second reason is electrical problems. For example, unstable power supply, electromagnetic coil disconnection or poor contact may affect the normal operation of the spindle.

Fault analysis of spindle of CNC machine tool with inclined bed

When the spindle fails, we need to carry out the corresponding maintenance work to restore its normal working state. Here are some suggestions and steps for your reference:

1, troubleshooting: First of all, it is necessary to find out the specific fault point through inspection and testing, and determine whether the problem is caused by the spindle itself, or other accessories or systems. You can make a preliminary judgment by checking the fault code, observing the running status of the spindle and listening to abnormal sounds.

2, lubrication maintenance: If found lubrication problems lead to spindle failure, should be dealt with in time. First of all, it is necessary to clean the lubrication system and replace the contaminated lubricating oil, ensure the normal oil supply, and perform regular lubrication maintenance according to the instructions in the machine tool manual.

3, parts replacement: If parts are found to be damaged or seriously worn, they need to be replaced in time. For example, when abnormal noise or increased friction is detected in the bearing, it should be replaced with a new part immediately. In addition, for electrical problems, it is also necessary to check whether the power line is in good contact and whether the electrical components are damaged, and repair or replace.

4, parameter adjustment and calibration: After completing the maintenance work, it is necessary to adjust and calibrate the spindle parameters according to the actual situation of the machine tool. This includes the adjustment of speed, steering, fastening force, etc., to restore it to normal operation under the premise of ensuring safety and stability.

5. Maintenance records and preventive measures: Finally, after completing the maintenance work, the maintenance process and results should be recorded in time, and corresponding preventive measures should be developed to avoid similar failures. This includes strengthening lubrication maintenance, regularly checking the condition of parts, and maintaining a stable power supply.

In short, in the process of using inclined bed CNC machine tools, spindle failure is a common but preventable and solved problem. By correctly eliminating the cause of the fault, timely maintenance and adjustment, can ensure the normal operation of the spindle, improve the performance of the machine tool and processing quality. At the same time, strengthening the daily maintenance of the machine tool is also an important means to prevent failures.

Only in continuous learning and practice to accumulate experience and take effective measures to deal with spindle failure, we can better use the inclined bed CNC machine tool to bring us high efficiency and accurate processing services.
