Engraving machine in normal use should be regularly cleaned of impurities, grease lubrication , otherwise operation of the engraving machine in the long screw . Rail internal bearings would be a lot of dust and impurities into the resulting screw for large rotational resistance of the bearing occurs engraving slightly faster speed will be lost step dislocation phenomenon. Maintenance methods:
1 Select lubricating materials : a mixture of oil and butter , and easy too thick.
2 , lubricated part :. Xyz -axis screw light bars .
3 , lubrication steps: pre- lubricated first screw, nut and bearing rails above the impurities removal , if the removal can not afford to , can be used to clean gasoline , lubricants and then gradually increase after the injection of a high speed idling , which hold plates, three-axis adjust.
4 , lubrication cycle : as the working environment and working time machine , and generally slag after work every day to clean out . Come on various parts monthly , high-speed idling lubrication.
5 , lubrication methods:
Y -axis : Lubrication is simple, relatively easy to clean up oil on both sides of the rail , you can screw into the bottom bracket grease from the Ministry , it is easier to maintain.
Remove the screws around the X-axis need to lift a head guard, ( Note: the left side of the line you want to relax reinstituted ) mentioning the right side completely open to the mixed oil injection rails, screw , bearing at the right side there thrust bearing at the screw head .
Z -axis of the cover to open , screw , rails, bearing bottom thrust bearing is very clear , this time done as follows: Note down the running mixed oil lubrication.
Triaxial lubrication when used within the hexagonal wrenches for hexagon socket screw coupling between the motor shaft and screw fastening head on , to prevent part of the three-axis due to mechanical loosening caused by misalignment .

Other maintenance parts:
Pumps. Cutting spindle , the two are mutual, must be frequently changed recycled water, keep the water clean and the water pump outlet to prevent clogging or water cutting spindle operating at high temperatures cause component damage.
