The common causes and solutions for the tool disc of a machining center getting stuck and unable to rotate are as follows:
I. Main Reasons
Abnormal spindle orientation Angle : orientation error caused by collision or loosening of the synchronous toothed belt
Tool change origin position offset : the origin is inaccurate due to misoperation of the machine tool or long-term use
Pneumatic/hydraulic system failure : insufficient pressure (6±1 kg for BT40) or damage to pneumatic components
Abnormality of the manipulator tool arm : the tool has not completely disengaged or the tool arm is damaged
Ⅱ. Solutions
Emergency handling :
Release the motor brake and use a wrench to rotate the outer hexagon to disengage the knife arm
Check if the air pressure meets the standard and clear the accumulated water in the gas line
System calibration :
Recalibrate the spindle orientation Angle (M19 command)
Adjust the position of the second tool changing origin
Preventive measures :
Regularly inspect the synchronous toothed belt and braking device
Avoid accidental operation and collision, and keep the airway dry
