  The cooling device of the   CNC machine   tool is as important as the lubricating device, and good cooling can effectively improve the processing quality of the workpiece and the life of the machine tool parts. Under normal circumstances, the daily maintenance of the cooling device is mainly the supply and replacement of the cooling liquid and the cleaning of the filter device. WHEN SHOULD THE COOLING DEVICE BE MAINTAINED? 1. Observe the oil mark in front of the water tank. When the cooling water decreases, it should be refilled in time. Generally, the configuration of the water outlet around the main shaft should at least make the oil filter at the suction port of the cooling pump completely submerged in the water. 2. When the cooling water is polluted and deteriorated, it should be replaced in time. Remove the screw plug under the water tank to discharge the waste liquid. After cleaning the water tank, fill in new, clean cooling liquid. 3. The cooling water tank is di...

  CNC milling machine common failures CNC milling machine  common failures: 1. Overtravel, when the feed movement exceeds the soft limit set by the software, the ultra-remote alarm content will occur. The fault can be eliminated and the alarm can be removed according to the CNC system manual. 2. Overload, when the load of the feed movement is too large, frequent forward and reverse movement and the feed transmission chain are in poor lubrication state, it will cause an overload fault. Generally, alarm information such as servo motor overload, overheating or overcurrent will be displayed on the CRT. At the same time, the feed drive unit overload and overcurrent information in the strong electric cabinet will be displayed. 3. Motion, the reasons for the motion phenomenon during feeding are: The speed measurement signal is unstable, such as the fault of the speed measurement device and the interference of the speed measurement feedback signal. The position control signal is bad o...
