1. Guide rail is damaged
If the machine tool for parts processing has been used for a long time, the level of the foundation and the bed has changed, so that the local unit area load of the guide rail is too large, the level of the bed guide rail should be adjusted regularly, or the accuracy of the guide rail should be repaired.
If it is a long-term processing of short parts or bear too concentrated load, so that the guide rail local wear serious, should pay attention to the reasonable distribution of the installation position of short parts, to avoid excessive concentration of load; If the guide is poorly lubricated, adjust the lubricating oil amount of the guide rail to ensure the lubricating oil pressure;
If the material of the guide rail is not good, the guide rail should be treated by electroplating heating and self-cooling quenching, and the zinc aluminum copper alloy plate should be added to the guide rail to improve the friction situation; If the scraping quality does not meet the requirements, the quality of scraping repair should be improved; The machine tool of parts processing is poorly maintained, and the stolen goods fall in the guide rail, the machine tool maintenance should be strengthened and the guide rail protection device should be protected.
2, the moving parts on the guide rail movement is poor or can not move
If it is the guide rail surface damage, you can use 180 # emery cloth to repair the grinding machine guide rail surface damage; If the pressure plate of the guide rail is damaged, remove the pressure plate and adjust the gap between the pressure plate and the guide rail; If the gap between the guide strip and the guide rail is too small and the adjustment is too tight, the insert stop screw should be loosened, the insert bolt should be adjusted, so that the moving parts are flexible, and the 0.03mm stopper should not be plugged in, and then the lock stop screw can be smoothly processed. Inner Mongolia machining.
3, the processing is uneven at the junction of the knife
If the straightness of the guide rail is out of line, the guide rail should be adjusted or repaired, and the tolerance is 0.015/500mm; If the stopper is loose or the bend of the stopper is too large, the gap of the stopper should be adjusted, and the bend of the stopper is less than 0.05mm/ full length in the natural state; If the levelness of the machine tool processed by the parts is poor, the guide rail is bent, and the installation level of the machine tool should be adjusted to ensure that the parallelism and verticality are within 0.02/1000mm.
