The machining center can't get rid of the knife

1. The machining center can not change the tool in the following cases:
1. Machine tool: 1. Mechanical failure. 2. Electrical or proceral failure< 2. Tool magazine: 1. Mechanical failure. 2. Electrical signal failure. 3. Hydraulic or pneumatic failure.

2. All machining centers will encounter this problem. Generally, in the process of tool change, mechanical failure and collision of the machine tool need to be pressed.

3. Insufficient air pressure

4. Try to bleed the cylinder for tool change

5. I have experienced this problem dozens of times. Ha ha, if the problem has not been solved, we can communicate with each other, but you can at least tell me what kind of tool magazine it is, and do you know the reason of the card, whether it is the limit switch broken or the air pressure is insufficient or because of misoperation? The general solution is relatively simple. Just turn off the air valve, push the tool magazine in place manually (you must touch the limit switch), and then turn off the power supply of the machine tool and restart it (by turning off the machine tool to reset. After the tool change of some machine tools is stuck, there is an air valve in the spindle that needs to be reset, but pressing the reset key of the machine tool is useless), and then turn on the air valve. If the same problem still occurs, Either the limit switch is broken, or the air pressure is insufficient, or there is a mechanical fault at the tool change position,

6. Is the automatic tool change system not working well? Still can't pull it out. BT, HSK or something. If it is difficult to unload each knife, you can consider checking whether there is scratch or deformation in the taper hole of the spindle. Beat with a dial indicator. The taper shank of the cutting tool shall be cleaned thoroughly, and the scratch shall be checked.

7. I don't have any points. I'm too lazy to answer
from what you said, your machine tool belongs to the common hat type tool magazine. This kind of tool magazine uses pneumatic action to make the cutter head move forward and backward. After the spindle is oriented, the cutter head pushes out the solenoid valve action. The next action can only be carried out after the inction switch is detected in place. This is the action principle here. Your machine just doesn't complete the push action and doesn't execute downward
therefore, it is not difficult to analyze the reason, 1. Whether the air pressure is appropriate
2 check whether the voltage is normal when the solenoid valve pushes out the command
3 whether the solenoid coil has magnetic force when the voltage is normal
3 this point is easy to be ignored by ordinary people, that is, whether the cutter head return detection switch position
is appropriate

simply put, check the air pressure, change the solenoid valve and check whether the signal is normal

from the point of view that it can be eliminated after 10 minutes of power off, the problem of solenoid valve accounts for a larger proportion

this small problem is easy to solve. Take your time.

8. There is a tool magazine motor on the top of the machine tool of the machining center. There is a shaft on the motor. Climb up and use a wrench to screw that shaft. The manipulator below will move with it. Just move it to the recovery position

9. The reason why the butterfly spring is tightly closed is that the ejector bar under the spindle cylinder is not in place, which causes the chuck not to release! If you don't loosen the chuck, of course the handle won't hold up

10. It's OK to execute the M6 tool change command again!
