Maintenance and upkeep of daily equipment in the machining center

　　In order to maintain the machine tool in good condition,in addition to timely repairs in case of malfunctions,it is very important to adhere to regular maintenance and upkeep.Adhering to regular inspections and regular maintenance can eliminate many hidden troubles in the bud and prevent or reduce accidents.

　　The key to maintaining CNC machine tools is to strengthen daily maintenance,and the main maintenance tasks include the following:

　　1.Daily inspection:main items include hydraulic system,spindle lubrication system,guide rail lubrication system,cooling system and Pressure system.Daily inspection is based on the normal condition of the system for testing.For example,when conducting a process inspection of the spindle lubrication system,the power light is on,and the oil 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 inspected correctly every week,especially for machine tool parts that need to be cleaned of iron filings and external debris.

　　3.Monthly inspection:mainly involves inspecting the power supply and air dryer.Under normal circumstances,the rated voltage of the power supply is 180v~220V,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 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 half a year,the hydraulic system,spindle lubrication system,and X-axis of the machine tool should be inspected.If problems occur,new oil should be replaced and cleaned.

　　CNC lathes integrate electricity,machinery,and fluid,with the characteristics of technology and knowledge intensive.They are highly automated,structurally complex,and expensive machining equipment.In order to fully utilize its benefits and reduce the occurrence of faults,it is necessary to do a good job in maintenance work.Therefore,it is required that CNC lathe maintenance personnel not only have knowledge in mechanical,processing technology,and hydraulic pneumatic aspects,but also have knowledge in electronic computers,automatic control,driving,and measurement technology.Only in this way can they fully understand and control CNC machine tools and timely carry out maintenance work.
