The key to preventive maintenance of CNC machining machine tools is to strengthen daily maintenance. The main maintenance tasks include daily inspection, weekly inspection, monthly inspection, quarterly inspection, and semi annual inspection. The specific preventive maintenance measures for CNC machining and CNC machine tools are as follows:

1. Daily inspection of CNC machining machines

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 condition of each system to detect. For example, when conducting a process inspection 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, the spindle should be kept in a stopped state and the mechanical engineer should be contacted. Perform repairs.

2. Weekly inspection of CNC machining tools

The main items include machine tool parts and spindle lubrication system, which should be properly inspected every week, especially for machine tool parts that need to be cleaned of iron filings and external debris.

3. Monthly inspection of CNC machining tools

Mainly for checking the power supply and air dryer. Under normal circumstances, the rated voltage of the power supply is 180V-220V, with a frequency of 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. Seasonal inspection of CNC machining machines

The quarterly inspection should mainly focus on three aspects: the machine bed, hydraulic system, and spindle lubrication system. For example, when inspecting the machine bed, the main focus is on whether the accuracy and level of the machine meet the requirements in the manual. If there are any problems, the mechanical engineer should be contacted immediately. When inspecting the hydraulic system and spindle lubrication system, if there are any problems, replace them with 6oL and 20L of new oil respectively, and clean them.

5. CNC machining CNC machine tool semi annual inspection

Six months later, the hydraulic system, spindle lubrication system, and X-axis of the machine tool should be inspected. If there are any problems, new oil should be replaced and cleaning work should be carried out. After fully familiarizing and mastering the knowledge of preventive maintenance, it is also necessary to have a deeper understanding and necessary mastery of the causes and handling of abnormal phenomena in the oil pressure system. When the oil pump does not spray oil, the pressure is abnormal, there is noise, and other phenomena occur, it is necessary to know the main reasons and what corresponding solutions are available.
