If the tail shaft of CNC Metal Spinning Machine moves forward and backward, but the tail shaft cannot move forward and backward, it may be the tail shaft cylinder, which can be solved by adding oil to the tail shaft to increase lubrication. In addition, it is also possible that after the nut connecting the cylinder and the tail shaft is loose, when the nut is re-tightened, it is not parallel to the tail shaft. The nut can be loosened, and the tail shaft and the cylinder are returned to the rear end to re-align and then tighten.
2. The tail shaft is extended, but the extension is not in place:
The tail shaft is extended, but the extension is not in place or the locking is not in place, and an alarm is given. You can press the reset button and try again. If you can't solve it, you need to open the tail box and adjust the position of the tail shaft forward position sensor. If it still can't be solved, judge whether the tail shaft advance position sensor is damaged, call up the diagnosis screen, check whether the change status of the tail shaft advance position sensor in the computer is normal when the power is turned on and power off, move the sensor by hand, the indicator light is on and off with the computer changes are consistent.
3. The solution to the alarm if the locking is not in place is the same as the above.
4. The tail shaft cylinder does not act:
It may be that the solenoid valve is damaged. You can manually press the solenoid valve manual button for manual operation. At the same time, press and hold the mold clamping, advance and retreat solenoid valve, and the tail shaft advances. Just press and hold the clamping solenoid valve, and the tail shaft moves back. It can be judged whether the solenoid valve is damaged by manual operation, and it can also be judged by referring to the status of the indicator lights of other solenoid valves.
This kind of failure generally occurs after the sensor is reinstalled and replaced, and the position of the sensor shaft cannot be the same as the original at this time. The orientation position of the spindle can be adjusted by setting data. Changing the positioning tolerance value of the spindle of CNC Metal Spinning Machine can correct the stop position of the spindle. When adjusting, pay attention to the input data and the direction to be corrected. When correcting the offset angle, a negative angle value cannot be entered after the positioning tolerance of the spindle. The adjustment process often has to be repeated many times. As long as the positioning tolerance of the spindle is adjusted within the range of 10-11 degrees, the mold can be replaced smoothly.
