Maintenance process of CNC machine tool

　　Numerical control technology is a comprehensive technology which integrates Bai computer technology, automation Du technology, measurement technology, modern mechanical manufacturing technology, microelectronics technology, information processing technology and so on. It is a comprehensive high-tech developed rapidly in the application field this year. It is suitable for the processing of high-precision, high-speed and complex parts. It is the basis of automation, digitization, flexibility, informatization, integration and networking. It is the soul and core of modern machine tool equipment. It has a wide range of application fields and broad application prospects. As a high-precision automation equipment, its safe and reliable operation depends on the correct use and daily maintenance of the machine tool. In order to ensure the long-term safe and stable operation of the machine tool, reduce the maintenance cost, timely discover and eliminate hidden dangers, so as to improve the economic benefits of enterprises.

　　The key to the maintenance of CNC machine tools is to strengthen regular maintenance. The main maintenance work includes the following contents:

　　1. Daily inspection: the main items include hydraulic system, spindle lubrication system, guide rail lubrication system, cooling system and air pressure system. The daily inspection is based on the normal condition of the system. For example, when the process detection of the spindle lubrication system is carried out, the power light is on, and the oil pressure pump should run normally. If the power light is not on, the spindle should be stopped and maintained with the mechanic.

　　2. Weekly inspection: the main items include machine parts and spindle lubrication system, which should be checked correctly every day, especially for machine parts, iron chips should be removed and external sundries should be cleaned.

　　3. Monthly inspection: mainly to check the power supply and air dryer. Under normal conditions, the rated voltage of the power supply is 180v-220v and the frequency is 50 Hz. 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.

　　4. Seasonal inspection: mainly from the machine bed, hydraulic system, spindle lubrication system three aspects of inspection. For example, the monitoring room of machine tool bed mainly depends on whether the accuracy and level of machine tool meet the requirements in the manual. If there is any problem, contact the mechanic immediately. When monitoring the hydraulic system and spindle lubrication system, if there are problems, they should be replaced with new oil and cleaned.

　　5. Semi annual inspection: after half a year, the hydraulic system, spindle lubrication system and x-axis of the machine tool shall be inspected. If there is any problem, the new oil shall be replaced and cleaned.
