Learn CNC machine operator daily checklist.Daily routine of a CNC operator to maintain the machine.
The operator should follow these points before starting the machine.And after shutdown the machine.
Checklist for Operator
| Points to be checked | Required value | Action to be taken |
| Oil Level Of Hydraulic tank & Automatic lubrication tank. | Oil level should above from half of Indicator. | If Oil level is low then Top Up oil and start the machine. |
| Cooling System of Hydraulic Tank/Chiller Unit. | Check the temperature.It should below 32°C. | If not ,then inform maintenance department./Check compressor and blower fan. |
| Cooling system of PLC/Electrical panel. | Below 25°C. | If not then set the temperature./Check compressor ,temperature sensor and blower fan. |
| Any leakage from Hydraulic power Pack/Valve. | There should not be any leakage. | If any leakage and inform to maintenance department. |
| Hydraulic Pressure. | Pressure should be according to manual(Drawing) of machine | If not then set the pressure. |
| Condition of Main Spindle /Chuck belt . | Belt should not slip during breaking. | Change the belt if it slips. |
| Any Abnormal sound from main motor/Spindle motor. | There should not be any sound from bearing. | Lubricate the bearing.Or check the oil flow to bearing. |
| Vibration in Spindle or Chuck. | There shoild not be vibration | If vibration is more then tighten the check nut of bearing adjustment.(For milling head of milling machine.).For lathe machine check the bearing of chuck. |
| Temperature of Spindle /Chuck(Bearing temp.) | Temperature in spindle should be less. | If temperature is more.Check the bearing.Inform to maintenance section.Lubricate the bearing. |
| Hydraulic Motor and Pump Coupling Condition. | Power transmission should smooth. | If there is vibration or noise then check the coupling. |
| Condition of Coolant. | Ratio of Coolant and water should be proper.Otherwise it will damage the bed/rust the bed. | Change the coolant if a bad smell comes from it. |

How do you maintain a CNC machine?
- Cleaning
Clean the machine every day before and after operation.
- Lubrication
Check the Automatic lubrication unit which lubricate the bed of all axis.Check the oil level of Gear box and hydraulic unit.
- Observation
Observe the vibration,any abnormal sound & temperature display.Check any leakage from hydraulic circuit.
- Preventive maintenance
Preventive Maintenance should be carried out regularly according to schedule.
- Predictive maintenance
If any part found abnormal during observation then rectify it.
