1. Dongguan CNC processing factory strictly abides by the operation rules and daily maintenance system,
2. dust and metal powder floating in the numerical control device can easily cause the insulation resistance between components to drop, thus causing failure or even damage to components.
3. clearing the cooling and ventilation system of the digital control cabinet at regular time
4. the voltage range of power grid of NC system is often monitored in 85% - 110% of rated value.
5. Dongguan CNC processing factory shall replace the battery for memory regularly
6. the maintenance of CNC system when it is not in use for a long time often electrifies the CNC system or makes the CNC machine run the temperature program.
7. maintenance of spare circuit board maintenance of mechanical parts maintenance of mechanical parts
1. maintenance of tool magazine and tool changing manipulator
① When installing the tool to the magazine manually, it is necessary to ensure that it is installed in place and check whether the locking on the cutter base is reliable;
② It is strictly forbidden to put the overweight and ultra long tools into the tool magazine to prevent the tool falling or the tool from colliding with the workpiece and fixture when the manipulator changes the tool;
③ Dongguan CNC processing factory adopts the method of sequential tool selection, and it is necessary to pay attention to whether the order of the tool is placed on the tool magazine is correct. Other tool selection methods should also pay attention to whether the tool number is consistent with the required tool, so as to prevent the accident caused by the wrong tool change;
④ Pay attention to keep the tool handle and tool sleeve clean;
⑤ Check whether the zero return position of the tool magazine is correct, check whether the position of the tool spindle return and change point is in place and adjust it in time, otherwise, the tool change action cannot be completed;
⑥ When starting, the magazine and manipulator shall be operated in air first, and check whether all parts work normally, especially whether the travel switches and solenoid valves can operate normally.
2. maintenance of ball screw pair
① Regularly check and adjust the axial clearance of screw nut pair to ensure the accuracy and rigidity of reverse drive;
② Check whether the connection between the screw support and the bed body is loose and whether the support bearing is damaged. If there are any above problems, fasten the loose parts in time and replace the support bearing;
③ The ball screw with grease is used to clean the old grease on the screw once every half a year and replace the new grease. The ball screw lubricated with lubricating oil shall be filled once every day before the machine tool is working;
④ Pay attention to avoid hard dust or chips entering the screw protective cover and the protective cover during the working process. The protective device shall be replaced in time if it is damaged.
3. maintenance of main drive chain in Dongguan CNC processing factory
① Adjust the tightness of the drive belt of the spindle regularly;
② Prevent all kinds of impurities from entering the tank. Replace the lubricating oil once a year;
③ Keep the connecting part of spindle and tool handle clean. The displacement of hydraulic cylinder and piston should be adjusted in time;
④ Adjust the counterweight in time.
4. hydraulic system maintenance
① Filter or replace oil regularly;
② Control the temperature of the oil in the hydraulic system;
③ Prevent leakage of hydraulic system;
④ Regularly check and clean the oil tank and pipeline;
⑤ Implement routine inspection system
5. maintenance of pneumatic system in Dongguan CNC processing plant
① Remove impurities and moisture from compressed air;
② Check the oil supply quantity of the oil mist device in the system;
③ Keep the system airtight;
④ Pay attention to adjusting the working pressure;
⑤ Clean or replace pneumatic components and filter elements;
