1. Daily inspection of CNC machine tools
Its important projects include hydraulic transmission system, main shaft bearing lubrication system, guide rail lubrication system, cooling system, and pneumatic operating system. Daily inspection is to check according to the normal conditions of each operating system. For example, when the whole process inspection of the main shaft bearing lubrication system is carried out, the switching power supply light should be on, and the oil pressure pump should be running normally. Repair.
2. Weekly inspection of CNC machine tools
Its important items include machine tool parts and spindle bearing lubrication systems, which should be properly checked every week, especially for machine tool parts to eliminate iron filings and clean up external dirt.
3. Monthly inspection of CNC machine tools
It is important to perform regular inspections of the switching power supply and air dryer. The working voltage of the switching power supply is normally 180V-220V, and the frequency is 50Hz. If there is any abnormality, it should be accurately measured and adjusted. The air dryer should be removed once a month, cleaned and installed.
4. Quarterly inspection of CNC machine tools
The quarterly inspection should mainly carry out routine inspections from three aspects: the machine tool bed, the hydraulic transmission system, and the spindle bearing lubrication system. For example, when routine inspection of the machine tool bed, it is important to see whether the precision of the machine tool and the level of the machine tool conform to the regulations in the manual. If there is any problem, you should immediately contact the mechanical engineer. During the routine inspection of the hydraulic transmission system and the main shaft bearing lubrication system, if there is any problem, the new oil 6oL and 20L should be replaced and cleaned respectively.
5. Semi-annual inspection of CNC machine tools
After more than half a year, the hydraulic transmission system, the main shaft bearing lubrication system and the X-axis of the machine tool should be routinely inspected. If there is a problem, the new oil should be removed and cleaned. After comprehensively understanding and mastering the common sense of preventive maintenance, it is also necessary to have a deeper understanding and essential mastery of the cause and treatment of abnormal conditions of the hydraulic operating system. For example, when the oil pump does not inject oil, the pressure is abnormal, and there is noise, etc., you should understand the main reasons and the corresponding solutions.
