The key to preventive maintenance of CNC machine tools is to strengthen daily maintenance. The main maintenance work includes the following: daily inspection, weekly inspection, monthly inspection, quarterly inspection and half-year inspection. The preventive maintenance of CNC machine tools is as follows:
1. Daily Inspection of CNC Machining Machine Tools
Its main projects include hydraulic system, spindle lubrication system, guide rail lubrication system, cooling system, air pressure system. Daily inspection is based on the normal conditions of each system to be tested. For example, when testing the process of the spindle lubrication system, the power supply lamp should be on, the oil pressure pump should be running normally, and if the power supply lamp is not on, the spindle should be kept in a stop state and contacted with the mechanical engineer. Maintenance.
2. Weekly Inspection of CNC Machining Machine Tools
Its main items include machine tool parts, spindle lubrication system, which should be checked correctly every week, especially for machine tool parts to remove iron chips and carry out external debris cleaning.
3. Monthly Inspection of CNC Machining Machine Tools
Mainly check the power supply and air dryer. The power supply voltage is rated at 180V-220V under normal conditions 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.
