The use and maintenance methods of machining centers?

1, Daily usage precautions
Check before startup
Check the lubricating oil level to ensure sufficient lubricating oil.
Check the coolant level to ensure that the coolant is sufficient.
Check if the air pressure is normal.
Check if the electrical system is functioning properly.
Clean the surface and chips of the machine tool to keep it clean.
Operating specifications
Start the machine tool according to the operating procedures to avoid sudden start and stop.
During the machining process, pay attention to observing the operating status of the machine tool. If there are any abnormal sounds or vibrations, stop the machine immediately for inspection.
Regularly check the wear of cutting tools and replace worn tools in a timely manner.
Maintenance after shutdown
Clean the inside and outside of the machine tool, including the control panel, spindle taper hole, tool holder, tool head, and remove dust and iron filings.
Check if the air blowing in the taper hole of the spindle is unobstructed, and wipe it with a cotton cloth before spraying light oil.
Clean the magazine arms and tools, especially the claws.
2. Daily maintenance
Daily maintenance
Clean the inside and outside of the machine tool to keep the equipment clean and tidy.
Check the level of lubricating oil and add lubricating oil in a timely manner.
Check if the coolant in the coolant tank is sufficient and add it in a timely manner.
Check the oil level height of the pneumatic triple component and eliminate any water vapor in the oil filter tank.
Check if the air pressure is normal and adjust it to the appropriate value.
Weekly maintenance
Clean the air filter, cooling pump, and lubricating oil pump filter of the heat exchanger.
Check if the tool bolt is loose and if the handle is clean.
Check if the three-axis mechanical origin is offset.
Check whether the movement of the tool changing arm or the rotation of the tool disc in the tool magazine is smooth.
Clean the impurities and moisture in the compressed gas, check the oil level in the oil mist separator, and ensure the sealing of the pneumatic system.
Monthly Maintenance
Check the lubrication condition of the X, Y, and Z three-axis tracks to ensure good lubrication of the track surface.
Check and clean the limit switch and bumper.
Check if the oil in the knife cylinder oil cup is sufficient and add it in a timely manner.
Check if the signs and warning labels on the machine are clearly visible.
Maintenance every six months
Remove the three-axis anti chip cover, clean the three-axis oil pipe joint, ball guide screw, and three-axis limit switch, and check their normality.
Check if the servo motors and heads of each axis are operating normally and if there are any abnormal sounds.
Replace the oil in the hydraulic unit and the oil in the tool magazine reducer.
Test the clearance between each axis and adjust the compensation amount if necessary.
Clean the dust inside the electrical box and conduct a comprehensive inspection of all contacts, connectors, sockets, and switches to ensure they are functioning properly.
Annual professional maintenance or repair
Check the integrity and working condition of the grounding protection system, circuit breakers, contactors, and other components.
Ensure the normal operation of the cooling fan inside the electrical cabinet, and check for any abnormalities in the fuses and air switches.
Check the vertical accuracy of each axis and adjust the geometric accuracy of the machine tool.
Check the wear and clearance of each shaft motor and screw, and replace damaged couplings or bearings.
Check the alignment of the screw rod and adjust the mechanical level.
Clean the cutting water tank and replace the cutting fluid.
Check the input/output devices of the CNC system and clean the electrical components inside the control cabinet.
3. The influence of environmental factors on machine tool maintenance
temperature control
Numerical control machine tools should avoid working in environments with excessively high or low temperatures as much as possible. Extreme temperatures can cause material expansion or contraction, thereby affecting the accuracy and stability of machine tools. Therefore, maintaining a suitable temperature environment is an important part of machine tool maintenance.
Humidity control
Excessive humidity can cause rusting of machine tool components, affecting the safety of electrical systems. Machine tools should be placed in a dry and ventilated environment to prevent corrosion caused by moisture.
Dust prevention measures
Dust not only damages the appearance of CNC machine tools, but also enters internal components, causing damage or wear. Therefore, it is essential to maintain a clean working environment and regularly clean the surface and internal components of the machine tool.
