In the Shenzhen precision machining industry, the preventive maintenance of CNC machine tools is crucial. Mechanical parts processing plant to strengthen the daily maintenance, the main content generally includes: daily inspection, weekly inspection, monthly inspection, quarterly inspection and semi-annual inspection. Shenzhen Perfect Precision Products Co., Ltd. combined with their own practical, talk about the preventive maintenance of CNC machine tools:.
1, CNC machine tools daily inspection
Daily inspection is based on the normal condition of the system to be tested. The main items are hydraulic system, spindle lubrication system, guide lubrication system, cooling system, pneumatic system, etc. For example, in the process of testing the spindle lubrication system, the power light should be on, the oil pressure pump should operate normally, if the power light is not on, the spindle should remain stopped and ask the master of precision machining for maintenance.
2, CNC machine tool weekly inspection
Weekly inspection of mechanical parts processing plant, its main items include machine tool precision parts, spindle lubrication system, should be properly inspected every week, especially machine tool precision parts to remove iron chips and external debris cleaning.
3, CNC machine tools monthly inspection
In the Shenzhen precision machining industry, the power supply and air dryer should be checked every month. Under normal circumstances, the power supply voltage rating of 180V-220V, frequency of 50Hz. if there are abnormalities, should be measured and adjusted. Air dryer should be disassembled once a month, and then cleaned and assembled.
4, CNC machine tool quarterly inspection
In the mechanical parts processing plant, quarterly inspection mainly from the machine bed, hydraulic system and spindle lubrication system three aspects. For example, when checking the machine bed, it mainly depends on the accuracy of the machine and whether the level of the machine meets the requirements of the manual. If there is any problem, the master precision machinist should be contacted immediately. When checking the hydraulic system and spindle lubrication system, if there is any problem, new oil 60l and 20l should be replaced and cleaned respectively.
5, CNC machine tool half-yearly inspection
After six months of processing, mechanical parts processing plant should check the machine tool hydraulic system, spindle lubrication system and X-axis. If any problems are found, the machine should be replaced with new oil, followed by cleaning work. After a comprehensive understanding and knowledge of preventive maintenance, it is necessary to better understand and necessary to master the causes and treatment of abnormal phenomena in the oil pressure system. For example, when the oil pump does not refuel, abnormal pressure, noise and other phenomena occur, the machine parts machining operator should know what the main causes are and what the corresponding solutions are.
