In order to maintain the good condition of the machine tool, in addition to timely repair in case of malfunctions, it is very important to adhere to regular maintenance and upkeep. Persisting in regular inspections and regular maintenance can eliminate many hidden dangers and prevent or reduce accidents from occurring.
The key to maintaining CNC machine tools is to strengthen daily maintenance, and the main maintenance tasks include the following:
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 conducted based on the normal condition of the system. For example, when conducting a process inspection of the spindle lubrication system, the power light is on, and the oil pressure pump should operate normally. If the power light is not on, the spindle should be kept in a stopped state and the mechanic should be contacted for maintenance.
2. Weekly inspection: Its main items include machine tool parts and spindle lubrication system, which should be checked correctly every week, especially for machine tool parts that need to be cleaned of iron filings and external debris.
3. Monthly inspection: mainly to inspect the power supply and air dryer. Under normal conditions, the rated voltage of the power supply is 180v~220v, with a frequency of 50Hz. If there is any abnormality, it should be measured and adjusted. The air dryer should be disassembled once a month, then cleaned and assembled.
4. Quarterly inspection: mainly inspect the machine bed, hydraulic system, and spindle lubrication system. For example, when inspecting the bed of a machine tool, the main focus is on whether the accuracy and level of the machine tool meet the requirements in the manual. If there are any problems, the mechanic should be contacted immediately. When inspecting the hydraulic system and spindle lubrication system, if there are any problems, they should be replaced with new oil and cleaned separately.
5. Half year inspection: After six months, the hydraulic system, spindle lubrication system, and X-axis of the machine tool should be inspected. If any problems occur, new oil should be replaced and cleaned.
