The key to preventive maintenance of CNC machining CNC machine tools is to strengthen daily maintenance. The main maintenance work has the following contents: daily inspection, weekly inspection, monthly inspection, quarter inspection, and semi-annual inspection. The preventive maintenance of CNC machining CNC machine tools is as follows:
1. Daily inspection of CNC machining CNC machine tools
Its main projects include hydraulic systems, spindle lubrication systems, rail lubrication systems, cooling systems, and pneumatic systems. The daily inspection is based on the normal conditions of each system. For example, when performing the process detection of the spindle lubrication system, the power light should be on, and the hydraulic pump should be running normally. If the power light is not bright, keep the spindle stopped and contact the mechanical engineer. Carry out repairs.
2. CNC machining CNC machine tool weekly inspection
The main items include machine tool parts and spindle lubrication systems, which should be properly inspected weekly, especially for machine parts to remove iron filings and external debris cleaning.
3. Monthly inspection of CNC machining CNC machine tools
Mainly to 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 removed once a month, then cleaned and assembled.
4. CNC processing CNC machine tool quarterly inspection
The quarterly inspection should be carried out mainly from three aspects: machine bed, hydraulic system, and spindle lubrication system. For example, when inspecting the machine bed, it is mainly to see whether the machine tool accuracy and machine tool level 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 the new oil 6oL and 20L separately and clean it.
5. CNC machining CNC machine tool semi-annual inspection
After half a year, the hydraulic system of the machine tool, the spindle lubrication system and the X-axis should be inspected. If there is a problem, the new oil should be replaced and then cleaned. After thoroughly familiarizing with and mastering the knowledge of preventive maintenance, you must have a deeper understanding and necessary grasp of the causes and treatment of abnormal phenomena in the hydraulic system. For example, when the oil pump does not spray oil, the pressure is abnormal, there is noise, etc., you should know what are the main reasons and what is the corresponding solution.
