Causes and solutions for tool jams in tool magazines of gantry machining centers and vertical machining centers

1. Incorrect spindle orientation angle

Orientation angle movement is generally caused by collision, or there is a problem with the synchronous tooth shape of the spindle, resulting in an error in the orientation angle. Inaccurate orientation will also cause problems such as abnormal tool change in the tool magazine.

2. Abnormal position of the second tool change origin

If the vertical machining center has a collision accident caused by misoperation, it is most likely to cause incorrect tool change origin, which is manifested as abnormal noise when the tool arm pulls out the tool and installs the tool during tool change, and even causes tool jamming. Over time, the tool arm will also be damaged.

In short, there are two situations in which the tool magazine is jammed. One is that the tool has not been pulled out, and the other is that the tool has been pulled out. The former situation is relatively easy to solve. We mainly introduce the solution to the second situation.

1. Release the brake device on the motor and use an adjustable wrench to rotate the outer hexagon on the motor. Generally, the direction of rotation is the same as the direction in which the tool arm is stuck. In short, the tool arm of the automatic tool changer is separated from the spindle of the vertical machining center.

2. When the tool arm is separated from the spindle, if there is a tool on the spindle, you can hear the sound of air leakage, that is, the spindle is in the state of loosening the tool. This is to pay attention to it. Be sure to put something on the tooling to prevent the tool from falling at this time.

3. Please keep rotating the tool arm until the tool arm completes a complete tool change action. The tool arm also has an origin position. There are three red lights in the tool magazine panel. Generally, the middle one is the indicator light that the tool arm is at the origin position.

4. After eliminating the tool jam fault, turn the brake device of the tool arm motor back to its original position, and then perform a tool change action in the MDI state of the vertical machining center to see if it is normal. If it is normal, please remember to check all the tools to be used for processing and perform processing under safe conditions.

When the tool magazine of the gantry machining center fails, we can perform preliminary repairs according to the above method. If it still cannot be used normally, we should seek help from professionals and do not dismantle the equipment privately to avoid damage to personal health.
