CNC Machine Center Daily Maintenance Notice

a．    Pre-start check

1)        Whether the oil level of the oil cooler, cutting fluid tank, air compressor, automatic lubricator, etc. is sufficient, must be confirmed.

2)        Please perform the water removal of the three-point combination filter.

3)        The operator himself must bundle the garments and wear protective gear.

4)        Whether the access power connection is normal or firm should be confirmed.

5)        Check if the air and lubricating oil pipelines are firmly connected.

6)        Remove obstacles around the machine.

7)        Whether the guards, doors and protective covers are closed or locked before the machine is started.

8)        Confirm the locking condition of each screw, and confirm the screw locking on the clamp.

9)        Check if the various safety devices are in position and function properly.

10)     Check if the tool on the spindle is loose or has other abnormalities.

b．    After start check

1)        Whether the supply of each lug surface of the lubricating oil is normal or sufficient, it must be confirmed.

2)        Whether the lighting equipment is working properly.

3)        Check whether the values of the indicator instrument such as oil cooler, cutting fluid pump, three-point combination and automatic lubricator are correct enough.

4)        Check if there is any noise or abnormality in the operation after starting.

5)        Confirmation of whether the power supply situation is normal.

6)        Check the pipeline for damage.

7)        Check for leaks and oil leaks between the sheet metal.

8)        Check if each moving shaft has vibration or jitter.

9)        Check if the actual machining accuracy is within the tolerance.

c．    Inspection at the end of daily work

1)        After the end of the daily work, the sweeping work must be thoroughly performed, and the machine should be checked for abnormal conditions (the compressed air can be used to remove the iron filings, but care should be taken when using it.

2)        The exhaust fan or filter of the electric control power box needs to be cleaned regularly.

3)        After the end of the job, be sure to turn off the main power switch. Turn off the power in the following order: Off Emergency stop → Turn off the Power off switch on the operation panel → Turn off the Main-Switch breaker of the power control box.

4)        If the chip bucket is full of chips, it should be removed immediately.

5)        Solenoid valve or electrical components, leave residual temperature after operation, even if the power is cut off, do not touch immediately.

6)        When the amount of oil shortage in each department is insufficient, it should be supplemented immediately according to the instructions. It should be replaced immediately if it deteriorates.

7)        At the end of the daily work, the machine should be checked for work to maintain the best workability of the machine.

8)        The chips inside the machine are concentrated to sweep the iron bucket.

1.1.2 Week, month, season, and year to check items

a．    Items to be checked weekly

1)          Check oil cooler, cutting fluid tank, and automatic lubricator tank sufficient?

2)         Whether the air pressure and lubricant piping are strong should be confirmed.

3)         Whether the supply of each slide surface of the slide oil is normal or sufficient.

4)         Confirmation of whether the voltage source and output are normal.

5)         Whether the chip bucket is stained with iron scraps.

6)         Confirmation of whether the components of each operation unit are operating normally.

7)         Air pressure three-point combination filter for cumulative moisture removal.

8)         View the temperature of the spindle cooler.

b．    Items to be checked each month

1)         Confirmation of whether the water content in the cutting fluid is too high.

2)         Confirm whether the oil level of the lock cylinder is sufficient.

3)         Clean the filter of the spindle cooler.

4)         Check if the assembly situation between the switches is normal.

5)         Confirmation of whether the supply of air pressure (hydraulic pressure) or voltage is stable.

6)         Confirmation of whether there is any leakage between the sheet metal.

7)         Check the connection action of the counterweight.

c．    Items to be inspected each season

1)        Check if the screws, nuts, joints, etc. are secure and not loose.

2)        Confirm and replace the cutting fluid.

3)        Whether the oil seal or gasket is leaking or damaged.

4)        Confirm the clearance between the cylinder and the boom, including the spring force of the disc spring.

5)        Confirmation of whether the slides are corroded or the lubrication of the skid oil is poor.

6)        Check whether the inlet of the air duct or the lubricating oil tube has an external leak.

d．    Items to be inspected each year

1)        Clean or replace the filter.

2)        Clean or replace the filter plate.
