CNC engraving machine spindle common failures and solutions

CNC engraving machine spindle is one of the types of motorized spindle, is mainly used in small and medium-sized carved device, with high speed engraving, drilling, slotting, and other functions. Engraving machine commonly used mainly include air cooling spindle and water-cooled spindle two kinds. In use, will inevitably fail, then what should I do? Carving factory under the home of Warwick CNC to introduce for everybody CNC engraving machine spindle common failures and solutions: 1, the boot after the spindle is not running the reason may be the main shaft above the plug not connected well or the inside of the line contact is not good, we need to check whether there is something wrong with the connection; Check if confirm the frequency converter if there is a signal or frequency inverter parameter Settings are correct; If also confirmed that no problem, may be the main shaft hardware stator coil has been burnt, need to return factory repair replace the coil. 2, switched on after a few seconds, the spindle downtime reasons may be a start time is too short, let spindle before work to extend the acceleration time appropriately, to achieve speed started carving later; It is possible that the spindle lacks due to the current protection, this needs us to check the spindle motor attachment is correct; The spindle internal water or water cooling is not enough, also easy to cause the hardware failure, need to return to factory maintenance. 3, switched on for a period of time the spindle shell hot smoking is serious or the first check the water pipe is unobstructed, also check the frequency converter set parameters is not correct, reset the frequency converter, if these two will be a problem, may be no output voltage, frequency and spindle nameplate rated voltage, frequency, we need to check the reference frequency converter. 4, the spindle nut loose when starting check if the spindle rotation error, if error is need according to the main shaft above the nameplate marking change the direction of rotation. 5 noise or spindle, spindle vibration basically all these problems is a hardware problem, beating heavily damaged bearing spindle is big, need to return to factory change new spindle bearings or replaced. 6, work no problem, when stop nut loose down time is too short, appropriately extended downtime. Above is CNC engraving machine spindle often some of the problems and solutions, if there are other fault, suggested main you contact carving factory house department or suppliers.
