In the process of using CNC machine tools, regular inspection is essential. Let's introduce the inspection contents in detail.

Regular inspections of CNC lathe

1. Guide rail lubrication station, check the oil level and oil quantity, add wetting oil in time, and the wetting pump can start and stop regularly.

2. X, y, Z, and each rotary shaft guide rail; Remove the cutting and dirt, check whether the lubricating oil is sufficient and whether the guide rail surface is scratched or damaged.

3. Compressed air source; Check that the pressure of the pneumatic control system is within the normal range.

4. Gas-liquid converter and supercharger; Check the height of the oilcloth, and replenish the oil in time if it is not enough.

5. Air dryer at the air inlet of the machine tool; Clean the water filtered from the water separator in time to ensure that the automatic air dryer works normally.

6. Spindle lubrication thermostatic oil tank; Normal operation, sufficient oil, and adjustment range.

7. Headstock hydraulic balance system; The balance pressure indication is normal, and the balance works normally during rapid movement.

8. Hydraulic system of the machine tool; The oil tank and hydraulic pump shall have no abnormal noise, the pressure gauge shall indicate normally, the pipelines and joints shall have no leakage, and the oil level shall be normal.

9. Input and output unit of the data stacking system; If the photoelectric reader is clean, the mechanical structure is well lubricated.

10. Various protective devices; Guide rail and protective cover of machine tool shall be free from looseness and water leakage.

11. Ventilation and heat dissipation device of the electric cabinet; The cooling fan of the electric cabinet works normally, and the air duct filter screen is not blocked.

How to do the daily maintenance of the CNC lathe well?

1. Select a suitable use environment to ensure the sanitation of the equipment site and prevent dust from entering the parts and affecting the compactness of the machined parts.

The operating environment of the equipment will also affect the normal operation of the machine tool, so the installation of the machine tool shall strictly comply with the installation conditions and requirements specified in the machine tool manual. When economic conditions permit, CNC lathes and general machining equipment shall be installed to facilitate repair and maintenance.

2. The daily maintenance of the CNC lathe shall be provided with special personnel for the programming, operation, and maintenance of the CNC system.

This personnel shall be familiar with the mechanical, numerical control system, strong current equipment, hydraulic, pneumatic, and other characteristics of the machine tool used, as well as the operating environment and processing conditions, and shall be able to use the machine tool correctly according to the requirements of the machine tool and system operating instructions.

3. Clean in time.

Such as the cleaning of the air filter and electrical cabinet, and the cleaning of the printed circuit board. The inspection of the machine tool cable is mainly to check whether the moving joint and the turning point of the cable have faults such as poor contact, broken wire, and short circuit.

4. Some numerical control systems use CMOS components for parameter memory, and the stored contents are maintained by the battery power supply in case of power failure.

In case of a low voltage alarm, the battery shall be replaced in time and the control system shall be powered on. Otherwise, the stored parameters will be lost and the CNC system will not work.
