1. The connection between the servo motor shaft and the lead screw is loose, causing the lead screw and the motor to be out of synchronization, resulting in dimensional error. During detection, it is only necessary to make marks on the coupling between the servo motor and the lead screw, and move the workbench (or tool rest) back and forth with a fast rate. Due to the inertia of the workbench (or turret), the two ends of the coupling will move relatively. This kind of fault usually shows that the machining size changes only in one direction, and it can be eliminated by uniformly tightening the coupling screws<\/p>\n\n\n\n
2. The poor lubrication between the ball screw and the nut increases the movement resistance of the workbench (or tool rest), and the movement command cannot be fully and accurately executed. This kind of fault usually shows that the size of the parts varies irregularly within a few wires, and the fault can be eliminated by improving the lubrication.<\/p>\n\n\n\n
3. The movement resistance of the machine tool table (or tool rest) is too large, which is generally caused by too tight adjustment of the inlay and poor lubrication of the machine tool guide rail surface. This fault phenomenon generally shows that the part size changes irregularly within a few wires. The inspection can be carried out by observing the size and change of the position deviation of dgn800-804. Generally, the difference is large when it is stationary in the positive and negative directions. This kind of fault only needs to readjust the insert and improve the lubrication of the guide rail.<\/p>\n\n\n\n
4. The rolling bearing is worn or improperly adjusted, resulting in excessive movement resistance. This fault phenomenon is also usually manifested as irregular variation in size within a few wires. The position deviation of dgn800-804 can be used for inspection. The method is the same as above. Such faults can be eliminated by replacing the worn bearing and carefully adjusting it.<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"
