How to Maintain Engraving Machine
The working time of the engraving machine should be controled within 10 hours a day; keep the cooling water clean and maintain the operation of the pump; never let the water dry in the spindle, exchange the cooling water regularly to prevent the high temperature of the water; in winter, if the operating ambient temperature is too low, you can use antifreeze to instead of the water in the tank.
After using of the machine, pay attention to clean up, make sure to clean up the dust on platform and transmission system, to lubricate and refuel the transmisson (X,Y,Z axis) system regularly(weekly); use the engine oil to maitain the X,Y,Z axis; add high-speed butter at screw part; if the working temperature is too low in winter, the screw and polished rod (square rail or round rail) part should be rinsed with gasoline, then add engine oil, otherwise the high resistance of the transmission parts will make the CNC router dislocation.
When you do the electrical maintenance checking, make sure to cut off power supply. after the monitor has no display and the main circuit power indicator light turns off, it can be carried out. after using the machine around three month, you should check the fastener, and tighten the screws of both sides of the gantry, the screw nut and both sides of the motor.
