How to maintain CNC machining CNC machine tools?

2021-09-18 15:56:15

CNC machining CNC machine tool preventive maintenance is the key to strengthen daily maintenance, the main maintenance work has the following content: daily inspection, weekly inspection, monthly inspection, quarterly inspection, semi-annual inspection. CNC machining CNC machine tool preventive maintenance details are as follows:

One, CNC machining CNC machine tool daily inspection

Its main projects include hydraulic system, spindle lubrication system, rail lubrication system, cooling system, air pressure system. Daily inspection is based on the normal conditions of each system to be detected. For example, when carrying out the process inspection of the spindle lubrication system, the power supply light should be on and the hydraulic pump should be in normal operation. If the power supply light is not on, the spindle should be kept in the stopped state and contact the mechanical engineer. Carry out repairs.

Two, CNC machining CNC machine tool weekly inspection

Its main projects include machine tool parts, spindle lubrication system, should be checked correctly every week, especially for machine tool parts to remove iron filings, external debris cleaning.

Monthly inspection of CNC lathe for CNC machining

It is mainly to check the power supply and air in the dryer. The rated voltage of the power supply is 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, and then cleaned and assembled.

Four, CNC machining CNC machine tools quarterly inspection

The quarterly inspection should be mainly from the machine bed, hydraulic system, spindle lubrication system three aspects of inspection. For example, when checking the machine bed, we mainly see 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, we should contact the mechanical engineer immediately. When the hydraulic system and spindle lubrication system are checked, if there are problems, they should be replaced with new oil 6oL and 20L respectively, and cleaned.

Semi-annual inspection of CNC machine tools

The hydraulic system, spindle lubrication system and X axis of the machine should be checked. If there is a problem, it should be replaced with new oil and then cleaned. After being fully familiar with and mastering the knowledge of preventive maintenance, we must also have a deeper understanding and necessary mastery of the cause and treatment of abnormal phenomena in oil pressure system. If the oil pump does not inject oil, the pressure is abnormal, there is noise and other phenomena, we should know what the main reasons are and what corresponding solutions are available.
