How to troubleshoot a CNC lathe once it fails

In the machinery industry, a large number of lathes are used, and they usually handle large objects. From this we also know that various problems may arise. Therefore, we need to troubleshoot and solve the corresponding faults to adapt to actual production needs and improve work efficiency. So, how to troubleshoot the failure of the CNC lathe? The following CNC lathe manufacturers will teach you a few tricks.

CNC machine tools

 1. According to the manufacturer of the CNC lathe, the size of the workpiece is accurate and the surface finish is poor. Eliminate the reasons for the failure of the CNC lathe: the cutter head is damaged, not sharp, the machine tool resonates, the placement is unstable, the machine tool crawls, and the processing technology is poor. Solution: After the tool is worn or damaged, the tool is not sharp, then re-sharpening or selecting a better tool to recalibrate the tool. The machine will resonate or be unevenly placed. Adjust the level, lay a good foundation and fix it steadily. The reason for mechanical crawling is that the dragging flat guide rail is severely worn, and the lead screw ball is worn or loose. The machine should be maintained.

 2. The workpiece has taper and small head. The manufacturer of the CNC lathe introduced the cause of the failure: the level of the machine is not adjusted correctly, one high and one low, resulting in uneven placement. When rotating the long shaft, the auxiliary material is relatively hard and the tool eats deeper, which causes the tool to loosen, and the tailstock thimble is not concentric with the spindle.

Solution: Use a level to adjust the level of the machine tool, lay a solid foundation, fix the machine tool to improve its toughness, select a reasonable process and appropriate cutting feed, to avoid the tool being forced to apply it to the knife, and adjust the tail frame.

3. According to the manufacturer of the CNC lathe, the light in the driving stage is normal, but the size of the workpiece to be processed is sometimes very large and sometimes very small. Solve the cause of the failure of the CNC lathe: the long-term high-speed operation of the machine tool carriage will cause the screws and bearings to wear, and the repeated positioning accuracy of the tool holder will cause deviations during long-term use. The carriage can accurately return to the starting point of machining every time, but the machining The size of the later workpiece is still changing.
