CNC Routine Maintenance

Continuous running time 10 hours a day, to ensure the normal operation of the cooling water pump clean and never make water appear spindle motor water shortages, regular replacement of cooling water to prevent the water temperature is too high. Winter temperature is too low if the work environment can be put into the water inside the tank antifreeze.

Each time the machine after use, pay attention to cleaning, be sure to dust on the platform and drive clean, regular (weekly) on the transmission system (X, Y, Z-axis) lubrication refueling. (Note: X, Y, Z-axis light rod with oil maintenance; screw speed section plus butter; winter temperature is too low if the work environment, screw, rod (square or round guide rail) part should be washed first with gasoline clean, then add the oil, otherwise it will cause too much resistance machine transmission parts dislocation caused by the machine.)

When electrical maintenance inspection, be sure to cut off the power supply when the monitor is no display and the main circuit power indicator light goes out before proceeding.

Engraving machine uses about three months should be checked for fasteners, screw connections on both sides of the gantry, the lead screw nut fastening screws on both sides of the motor fastening screws tightened.

1. Machine doesn’t work accurately Change the motor of every axis or change the motor driver. Use ground wire Fasten the linker of the screw ball.
    2. Machine doesn’t work after opened (including the machine don’t go home) The switch is broken, change a new switch There is something wrong with the power, check or change the power Check the cable connected with the switch and pin in one side of the cable.
    3. X-axis or y-axis doesn’t move Usually it is the problem of the stepper motor, driver and cable connected with the x-axis or y-axis, check them and correct. 
    4. How to protect the vacuum hold down table don’t hollow out the material when engraving.
