How should CNC machining equipment be maintained daily?

The daily maintenance of CNC machining includes: daily inspection, weekly inspection, monthly inspection, quarterly inspection, and semi-annual inspection. The preventive maintenance of CNC machine tools is as follows:

1. Daily inspection of CNC machining CNC machine tools
Its main projects include hydraulic system, spindle lubrication system, guide rail lubrication system, cooling system, and pneumatic system. Daily inspection is based on the normal conditions of each system to be tested. For example, when the process of the spindle lubrication system is tested, the power light should be on and the oil pump should operate normally. If the power light is off, the spindle should be kept in a stopped state and contact the mechanical engineer. Carry out repairs.

2. Weekly inspection of CNC machining CNC machine tools
Its main items include machine tool parts and spindle lubrication system, which should be checked correctly every week, especially for machine tool parts to remove iron filings and clean up external debris.

3. Monthly inspection of CNC machining CNC machine tools
Mainly check the power supply and the 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 must be measured and adjusted. The air dryer should be disassembled once a month, and then cleaned and assembled.

4. Quarterly inspection of CNC machining CNC machine tools
The quarterly inspection should be conducted mainly from the three aspects of the machine bed, hydraulic system, and spindle lubrication system. For example, when inspecting the machine bed, it mainly depends on whether the accuracy of the machine tool and the level of the machine tool meet the requirements in the manual. If there is any problem, you should contact the mechanical engineer immediately. When inspecting the hydraulic system and the spindle lubrication system, if there is any problem, replace with new oil 6oL and 20L, and clean it.

5. Semi-annual inspection of CNC machining CNC machine tools
After half a year, the hydraulic system, spindle lubrication system, and X-axis of the machine tool should be checked. If something goes wrong, the oil should be replaced and then cleaned. After comprehensively familiarizing and mastering the knowledge of preventive maintenance, it is necessary to have a deeper understanding and necessary mastery of the causes and treatment of abnormal phenomena in the hydraulic system. If the oil pump does not inject oil, the pressure is abnormal, or there is noise, it should be repaired and dealt with in time.
