With the development of science and technology, the automation and intelligence level of modern mechanical manufacturing industry is becoming higher and higher, and CNC machines are increasingly applied to production and manufacturing, promoting the development of modern mechanical manufacturing industry. The automation and intelligence level of CNC machines is relatively high, and the maintenance and upkeep of CNC machine tools also have high technical requirements.

In daily use, it is not only necessary to strengthen the rational use of CNC machines, but also to adopt scientific and reasonable maintenance methods to provide guarantee for the normal use of CNC machines. Good maintenance is the guarantee for the smooth production of enterprises. CNC machines are expensive. Maintenance during use will help reduce the loss of CNC machine parts, improve the service life of CNC machine tools, and ensure the normal use of machines. At the same time, good maintenance can effectively reduce the mechanical failure of CNC machines, reduce the probability of production safety accidents, and ensure the safe production of enterprises.

The proper routine maintenance of CNC machines will directly affect the accuracy of the machining center and even affect the service life of the machine.

1.Doing a good job in the maintenance and upkeep of mechanical systems plays an important role in mechanical production. The importance attached to the maintenance and upkeep of CNC machines is increasing, and the maintenance and upkeep of CNC machines have become an important task for the industry. Do a good job in the maintenance of CNC machines, and strengthen the maintenance of mechanical systems, mainly including the maintenance of the main transmission chain, hydraulic system, pressure system, and machine accuracy. Do a good job in the maintenance of the main transmission chain, regularly adjust the tightness of the spindle drive belt, and also check the temperature range of the constant temperature oil tank for spindle lubrication, replenish the oil amount, and clean the filter; As the power system of CNC machines, the hydraulic system should be regularly inspected, including the oil, cooler, heater, hydraulic components, filter elements, and other components of the hydraulic system in the oil tank. Enterprises should do a good job in the maintenance and upkeep of mechanical systems, strengthen investment in mechanical system maintenance and upkeep, and provide hardware support for the normal use of CNC machine tools.

2.Do a good job in the management of the CNC system and develop a reasonable maintenance system. CNC machines have high requirements for temperature, humidity, gas, etc. in the workplace. During use, it is necessary to do a good job in the management of CNC machine tools and develop a reasonable maintenance system. To do a good job in the maintenance and upkeep of CNC machine tools, enterprises need to develop reasonable maintenance systems and comprehensive operating procedures, and update existing systems and procedures based on the development of technology and practical needs, in order to keep up with the times. At the same time, enterprises should do a good job in the management of CNC systems, strengthen the management of impurity prevention in CNC systems, timely clean up dust and impurities inside CNC machine tools, and provide a clean workplace for the use of CNC machine tools; Do a good job in cleaning the ventilation system of the CNC cabinet, and promptly clean the ventilation system to ensure that the heat generated during the operation of the CNC machine tool is dissipated in a timely manner, providing guarantee for the normal operation of the CNC machine.

In addition, operators should clean and tidy the machine tool after work every day, clean iron filings, and wipe the cooling liquid on the guide rail to prevent rust on the guide rail. Wipe the machine tool clean with a cloth when leaving work to avoid rusting.
