1. Daily inspection of CNC machining CNC machine tools
Its key names include hydraulic system, spindle smoothing system, guide rail smoothing system, cooling system and pneumatic system. The daily inspection is based on the normal condition of each system. For example, when performing the process detection of the spindle smoothing system, the power light should be on, and the hydraulic pump should be running normally. If the power light is not bright, the spindle stop mode should be maintained, which is related to the mechanical engineer. Carry out repairs.
2. CNC machining CNC machine tool weekly inspection
Its key names include machine tool parts and spindle smoothing systems, which should be accurately tested every week. The unique feature is to eliminate iron filings on machine parts and perform external debris removal.
3. Monthly inspection of CNC machining CNC machine tools
If the main test is to check the power supply and air. The power supply voltage is rated at 180V-220V under normal conditions, and the frequency is 50Hz. If it is exceptional, it should be measured and adjusted. The air dryer should be removed once a month and then washed and equipped.
4. CNC processing CNC machine tool quarterly inspection
The quarterly inspection should focus on the inspection of the machine bed, hydraulic system and spindle smoothing system. For example, when inspecting the machine bed, it is important to see whether the machine tool accuracy and machine tool level meet the requirements in the manual. If there is any problem, it should be related to the mechanical engineer. When inspecting the hydraulic system and the spindle smoothing system, if there is any problem, you should change the new oil 6oL and 20L and wash it.
5. CNC machining CNC machine tool semi-annual inspection
After half a year, the hydraulic system of the machine tool, the smoothing system of the spindle and the X-axis should be inspected. If there is a defect, the new oil should be exchanged and then washed. After thoroughly understanding and managing the knowledge of prevention and care, it is also necessary to have a deeper understanding of the causes and treatment of the extraordinarily significant phenomenon of the hydraulic system. For example, when the oil pump does not spray oil, the pressure is abnormal, there is noise, etc., it should be known what the key reasons are, and what is the corresponding treatment.
For the sake and treatment of the extra phenomenon of the oil pressure system, the focus should be understood from three aspects:
(1) The oil pump does not spray the main reason. There may be low liquid level in the fuel tank, reversed oil pump, insufficient speed, high oil viscosity, low oil temperature, filter congestion, excessive suction pipe capacity, and suction at the oil inlet. There are damages to the air, shaft and rotor. For the sake of the key reasons, there are corresponding treatment methods, such as filling the oil, confirming the label, and changing when the oil pump is reversed.
(2) The pressure is abnormal. The pressure is too high or insufficient. The key reasons are also various, such as improper pressure setting, poor behavior of the pressure regulating valve coil, abnormal pressure gauge, and leakage of the oil pressure system. Corresponding treatment methods include dismantling and washing according to the pressure of the regulations, changing a normal pressure gauge, and checking according to each system.
(3) Noisy Noise is mainly caused by oil pumps and valves. When the valve is noisy, the reason is that the flow rate exceeds the rated standard, and the flow rate should be properly adjusted; when the oil pump has noise, the reason and its corresponding treatment methods are also various, such as high viscosity of oil, low oil temperature, and treatment method. To raise the oil temperature; when there are bubbles in the oil, the air in the system should be released.
