Maintenance and care of CNC machine tools

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
