The engraving machine is a high-precision numerical control device that requires regular maintenance to ensure its longevity and accuracy. Proper daily care is essential for optimal performance and safe operation. Here are some key maintenance procedures you should follow:
First, during operation, always make sure the water cooling system is functioning properly. The pump must be working correctly, and the spindle motor should never experience a water shortage. It's important to replace the cooling water regularly to prevent overheating. In colder environments, especially during winter, it's recommended to add antifreeze to the cooling tank to avoid freezing and damage.
Second, when the machine is in use, oil should be supplied to the oil circuit via the oil pump. After each use, take time to clean the worktable and drive system thoroughly. Remove any wood chips or debris from the spindle nut and spring knife clip. Additionally, perform a weekly inspection of the oil system to ensure smooth operation and prevent mechanical issues.
(Note: The X, Y, Z axes guide rails should be lubricated with engine oil, while the screw parts require high-speed grease. In cold weather, if the ambient temperature is too low, it's advisable to first clean the screw rod and guide rails with gasoline before applying oil. This prevents excessive resistance in the transmission system, which could lead to misalignment or damage.)
Third, when performing electrical maintenance, always turn off the power supply and wait until the display turns off and the main circuit indicator light goes out. Regularly check the connections between the distribution box and the machine for any looseness. Clean dust from frequently used electrical components like relays and AC contactors. If any unusual behavior is detected, repair or replace the affected circuits immediately to avoid further complications.
By following these maintenance steps, you can significantly extend the life of your engraving machine and maintain its precision over time. Always refer to the manufacturer’s manual for specific instructions and recommendations tailored to your model.
