How to solve the problem of tool jamming in large CNC machining centers

Large CNC machining centers are high-efficiency automated machine tools composed of mechanical equipment and CNC systems suitable for processing complex parts. CNC machining centers are one of the world's high production and widely used CNC machine tools.

1. Release the brake device on the motor and use a monkey wrench to rotate the outer hexagon on the motor. Generally, the direction of rotation is the same as the direction of the tool arm getting stuck. In short, the automatic tool changing tool arm is separated from the spindle of the CNC machining center.

2. When the tool arm is detached from the spindle, if there is a tool on the spindle that can hear air leakage, which is the state when the spindle is in the state of loosening the tool, it is important to place something on the fixture to prevent the tool from falling.

3. Please keep rotating the blade arm until it completes a complete tool change motion. The tool arm also has an origin position, and there are three red lights inside the tool magazine panel. Generally, the indicator light in the middle that lights up is the tool arm at the origin position. The tool holder is not in place or cannot stop rotating, which is a solution. When encountering a tool holder that is not in place, does not return to zero, or rotates continuously, it is necessary to first check the oil pressure in the oil circuit and whether the oil pump is working properly. If these are all correct, it is necessary to inspect the braking device.
