1. Classification and application of CNC machine tools With the development of CNC technology, CNC machine tools have become more and more widely used in the processing and production of enterprises. There are many types of CNC machine tools, but they are mainly classified according to the machining methods and machining processes of the machine tools. Modern factories mainly focus on metal cutting, which can be roughly divided into CNC milling machines, CNC boring machines, CNC vertical lathes, CNC grinding machines and machining centers.
2. Characteristics of CNC machine tool maintenance CNC machine tools are different from traditional machine tool maintenance. It is a mechatronics product integrating CNC system, programmable controller, servo system and precision machinery. The maintenance of CNC machine tools should follow the following points: First, be familiar with the working principle, characteristics and handling of common faults of CNC system, position detection and servo drive and auxiliary control. Second, we must know how to make full use of the fault information provided by NC and plc to find faults. To analyze the specific problem, we can determine the accurate treatment of the fault.
3. Basic steps of fault diagnosis and maintenance of CNC machine tools The maintenance process of CNC machine tools is mainly divided into three stages. First, after the scene is reached, the on-site investigation and the collection of fault information are performed. Carefully ask the machine operator's fault surface indication and the background of the fault, and make a preliminary judgment on the fault phenomenon. Secondly, carry out specific maintenance according to the investigation results and fault phenomena on site. From easy to difficult, from the outside to the inside, gradually narrow the search range, determine the location of the fault and take correct maintenance measures. Finally, after the fault of the machine tool is removed, the operator is informed of the cause of the fault and the information and link of the fault, and the precautions for future operation are avoided to avoid similar faults in the future. At the same time, make maintenance records and reserve for future maintenance.
