When the NC machine tool is not used for a long time, the machine tool shall be sealed according to the regulations. Clean the inside and outside of the CNC system, put on the protective cover and cut off the power supply. If the CNC system is idle for a long time, it needs to be powered on frequently, especially in the rainy season with high ambient humidity.
Daily inspection
Its 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 conditions of each system. For example, during the process detection of the spindle lubrication system, the power light should be on and the oil pump should operate normally. If the power light is not on, keep the spindle stopped and contact the mechanical engineer. Repair.
2. Weekly inspection
The main items include machine tool parts and spindle lubrication system, which should be correctly inspected every week, especially for machine tool parts, iron filings should be removed and external sundries should be cleaned.
3. Monthly inspection
Mainly check the power supply and air dryer. Under normal conditions, the rated power supply voltage is 180v-220v and the frequency is 50Hz. In case of abnormality, it shall be measured and adjusted. The air dryer should be disassembled once a month, and then cleaned and assembled.
4. Quarterly inspection
The quarterly inspection should mainly be carried out from three aspects: machine bed, hydraulic system and spindle lubrication system. For example, when checking the machine bed, it mainly depends on whether the accuracy and level of the machine tool meet the requirements in the manual. If there is any problem, contact the mechanical engineer immediately. When checking the hydraulic system and spindle lubrication system, if there is any problem, replace 6ol and 20L oil respectively and clean them.
5. Semi annual inspection
After half a year, the hydraulic system, spindle lubrication system and x-axis of the machine tool should be checked. In case of any fault, the oil should be replaced and then cleaned.
