CNC engraving machine spindle common failure analysis

CNC engraving machine spindle common failure analysis: 1. Spindle motor burning. Solution: check whether the water pump is working, circulating water is low level. 2. Spindle motor abnormal sound. Solution: 1, if motor overload operation; 2, motor is internal fault, repairing or replacement. 3. Spindle motor. Solution: check whether the motor line lack of phase, whether cable short circuit 4. Spindle motor reversal. Solution: check whether the motor line phase or the output UVW side switch
