To put it simply, there are two cases of the knife magazine knife. One is that the tool has not been unplugged, and the other is that the tool has been removed. The first case is relatively well solved. We mainly introduce the solution of the second case.
　　1. Loosen the brake device on the motor and use the adjustable wrench to rotate the outer hexagon on the motor. The direction of rotation is generally the same as the direction of the jamming of the arm. In short, the arm of the automatic tool changer is separated from the high-speed vertical machining center. Spindle.
　　2. When the arm is off the spindle, if there is a tool on the spindle, you can hear the air leakage sound, that is, the state that the spindle is in the state of loosening the knife. It is necessary to pay attention to the fact that the tool must be padded on the tooling. The situation has happened.
　　3. Please rotate the arm until the tool arm completes a complete tool change. The arm also has an origin position. Inside the magazine panel, there are three red lights inside. Generally, the bright one in the middle is the indicator light at the origin of the arm.
　　4. After the card cutter is faulty, turn the arm motor brake device back to the original position, and then perform a tool change operation in the MDI state of the high-speed vertical machining center to see if it is normal. If it is normal, please remember to All the tools to be used for the machining are checked once and processed while ensuring safety.
