The daily maintenance of CNC machine tools requires maintenance personnel to not only have knowledge of mechanics, processing technology and hydraulics, but also knowledge of electronic computers, automatic control, drive and measurement technology, so that they can fully understand and master CNC lathes in a timely manner. maintenance work. The main maintenance work includes the following:
(1) Choose a suitable usage environment
The usage environment of CNC lathes (such as temperature, humidity, vibration, power supply voltage, frequency and interference, etc.) will affect the normal operation of the machine tool. Therefore, when installing the machine tool, you should strictly comply with the installation conditions and requirements specified in the machine tool manual. When economic conditions permit, CNC lathes should be installed isolated from ordinary mechanical processing equipment to facilitate repair and maintenance.
(2) Equipped with specialized personnel for CNC system programming, operation and maintenance
These personnel should be familiar with the mechanical, CNC system, strong electrical equipment, hydraulic, pneumatic and other characteristics of the machine tools used, as well as the usage environment, processing conditions, etc., and be able to use CNC lathes correctly according to the requirements of the machine tool and system operating instructions.

(3) CNC lathe runs regularly
When the CNC lathe is idle, the CNC system should be powered on frequently and run dry when the machine tool is locked. During the rainy season when the air humidity is high, power should be turned on every day, and the electrical components themselves should be used to generate heat to drive away the moisture in the CNC cabinet to ensure that the performance of the electronic components is stable and reliable.
(4) Inspection of machine tool cables
Mainly check whether there are faults such as poor contact, disconnection and short circuit at the moving joints and corners of the cable.
(5) Replace the battery promptly
The parameter memory of some CNC systems uses CMOS components, and the stored content is maintained by battery power when the power is off. When a low-voltage alarm occurs, the battery must be replaced in time, and it must be done when the control system is powered on, otherwise the stored parameters will be lost and the CNC system will not work.
(6) Ensure hygiene and cleanliness
Such as cleaning of air filters, electrical cabinets, and printed circuit boards.
