How to perform daily maintenance on CNC machine tools?

The main items include hydraulic system, spindle lubrication system, guide rail lubrication system, cooling system, and air pressure system. Daily inspection is to detect according to the normal situation of the system. For example, when the process inspection of the spindle lubrication system is carried out, the power light is on and the hydraulic pump should operate normally. If the power light is not on, the spindle should be kept stopped and the mechanic should be contacted for maintenance.

1. Daily inspection: The main items include hydraulic system, spindle lubrication system, guide rail lubrication system, cooling system, and air pressure system. Daily inspection is to detect according to the normal situation of the system. For example, when the process inspection of the spindle lubrication system is carried out, the power light is on and the hydraulic pump should operate normally. If the power light is not on, the spindle should be kept stopped and the mechanic should be contacted for maintenance.

2. Weekly inspection: The main items include machine tool parts and spindle lubrication system, which should be properly inspected every week, especially the iron filings should be cleaned for machine tool parts and external debris should be cleaned.

3. Monthly inspection: It mainly inspects the power supply and air dryer. The rated voltage of the power supply is 180v~220v under normal circumstances, and the frequency is 50hz. If there is any abnormality, it should be measured and adjusted. The air dryer should be disassembled once a month, and then cleaned and assembled.

4. Quarterly inspection: mainly inspect the machine tool bed, hydraulic system, and spindle lubrication system. For example, when inspecting the machine tool bed, mainly check whether the machine tool accuracy and machine tool level meet the requirements in the manual. If there is any problem, contact the mechanic immediately. When inspecting the hydraulic system and spindle lubrication system, if there is any problem, replace the new oil respectively and clean them.

5. Half-year inspection: After half a year, the hydraulic system, spindle lubrication system and X-axis of the machine tool should be inspected. If there is any problem, replace the new oil and clean them.
