CNC lathe manufacturers explain the six preparation items before maintaining
CNC lathes The maintenance of a CNC lathe is a necessary and important task for operating a CNC lathe. It not only effectively improves the performance of the lathe itself but also identifies potential dangerous faults of the lathe. Regular maintenance can also improve the service life of the CNC lathe itself. Today, we, the CNC lathe manufacturer, will explain the six preparation items before game maintenance of the CNC lathe.

(1) Strictly follow the operating procedures of the CNC machine

The programming, operation, and maintenance personnel of the CNC system must undergo specialized technical training, be familiar with the CNC system, strong current equipment, machinery, hydraulic pressure, air source and other parts of the CNC machine tool used, as well as the usage environment and processing conditions. They must be able to use the machine tool and CNC system correctly and reasonably according to the requirements of the user manual; Efforts should be made to avoid malfunctions caused by improper operation.

(2) Preventing overheating of CNC devices

Regularly clean the cooling and ventilation system of the CNC device: Regularly check whether the cooling fan on the CNC device is working properly. Pay attention to the operating environment of the machine tool and inspect and clean it every quarter or every six months.

(3) Prevent dust from entering the CNC device

In addition to maintenance, electrical cabinet doors should be opened as little as possible. Because dust, oil mist, and metal powder floating in the space near the machine tool fall on printed circuit boards and electrical connectors, it is easy to cause a decrease in insulation resistance between components, leading to faults and even damage to components. The spindle control system of some CNC machine tools is placed in a strong electrical cabinet, and the weak closing of the strong electrical door is one of the reasons for electrical component failure and spindle control failure. Some users simply open the door of the CNC cabinet and use an external fan to blow air into the cabinet when the temperature is too high in summer, in order to reduce the temperature inside the machine and barely maintain its operation. This method will ultimately lead to system acceleration damage.

(4) Regular inspection and replacement of backup batteries for storage

The machining program of the CNC system Machine tool data is generally stored randomly in CNC devices In the storage system, when the power is cut off, it is maintained by the backup battery. When the battery energy drops to a certain value, data and programs will be lost. If the system is continuously powered on, it will generate an alarm, and the battery must be replaced within a week after the alarm occurs. However, it is best to check the battery voltage frequently. When the battery voltage drops to a certain value, it should be replaced early, or for reliable operation, the battery should be replaced once a year. When replacing or checking the battery voltage, it is necessary to Perform it while the system is powered on, so as not to lose machine data and programs.

(5) Regularly check the power supply voltage of the CNC system

The allowable power supply voltage of the CNC system is usually 85%~% of the rated value. If it exceeds this range, it may cause unstable operation of the CNC system, and in severe cases, it may cause damage to some electronic components. Therefore, it is important to pay attention to voltage fluctuations in the power grid. For areas with poor power grid quality, timely configuration of dedicated AC stabilized power supply devices for CNC systems should be carried out, as this will significantly reduce the failure rate of CNC systems.

(6) Maintenance of CNC systems when not in use for a long time

When CNC machine tools are idle for a long time, regular maintenance and upkeep of the CNC system should also be carried out. Firstly, the CNC system should be regularly powered on and allowed to run idle when the machine tool is locked in place. During the rainy season with high air humidity, it should be powered on every day to use the heating of electrical components to dissipate moisture in the CNC cabinet, ensuring stable performance of electronic components. Practice has proven that frequently idle machine tools are prone to various malfunctions after the rainy season.

The above are the six preparation items for maintenance of CNC lathes compiled by our CNC lathe manufacturer, hoping to be helpful for everyone in using CNC lathes in the future.
