The reliability and accuracy of CNC machine tools depend largely on the daily maintenance of CNC system components.By formulating a scientific maintenance plan, strictly implementing it, and supplemented by real-time monitoring and preventive maintenance, you can minimize unexpected downtime, extend the service life of the machine tool, thereby improving production efficiency and reducing costs.
Maintenance of CNC machine tools
Strictly abide by operating procedures and daily maintenance system
Open the doors of CNC cabinet and power cabinet as little as possible to prevent dust, oil mist and other contamination of circuit boards
Regularly clean the heat dissipation and ventilation system of CNC cabinet, check cooling fan and filter
Regularly check and replace brushes of DC motor
Regularly replace storage batteries, generally once a year
When spare circuit boards are not used for a long time, they should be powered on regularly

Maintenance of mechanical parts
Check and adjust the tightness of the spindle drive belt to prevent slippage and loss of rotation
Check the oil level and temperature of the spindle lubricating oil tank, and replenish and clean the filter in time
Regularly check and adjust the axial clearance and connection tightness of the ball screw
Replace damaged screw guards in time
Check whether the guide rail surface is scratched and whether the lubrication is sufficient
Daily maintenance CNC machine tools
Remove chips, dust and other dirt every day and wipe the surface of the machine tool
Check the amount of lubricating oil and add it in time
Check the concentration and level of coolant and replace it if necessary
Check pneumatic parts such as air pressure and filters
Regularly clean the machine tool, including the parts that are not easy to reach
Regularly calibrate the accuracy of the machine tool
Develop maintenance plans and records
Develop daily, weekly, monthly, and annual maintenance plans based on manufacturer recommendations and actual usage
Clearly define the content, methods, and responsible persons for maintenance
Keep maintenance records and track changes in machine tool status
Update and optimize maintenance plans in a timely manner
Always have key spare parts
Prepare spare parts with wearing parts and long procurement cycles in advance
Replace damaged parts as soon as possible to reduce downtime
