1. Maintenance management content
CNC machine tools should establish safety operation procedures, maintenance procedures and repair procedures, which can be formulated by adding the characteristics of CNC machine tools on the basis of the corresponding procedures of traditional machine tools. Compared with traditional machine tools, the maintenance management of CNC machine tools should emphasize the following:
Choose a reasonable maintenance method
Equipment maintenance methods can be divided into post maintenance, preventive maintenance, improved maintenance, predictive maintenance or condition monitoring maintenance, maintenance prevention (no maintenance design), etc. to choose the best maintenance method is to use the least cost to achieve the best repair effect.
If we measure it from the aspects of repair cost, shutdown loss, maintenance organization work and repair effect, each maintenance method has its advantages and disadvantages. In addition to realizing automatic tool exchange, automatic workpiece exchange and automatic measurement compensation, modern CNC machine tools also have the functions of automatic monitoring and automatic diagnosis.
Maintenance of CNC machine tools You can choose predictive maintenance or condition monitoring maintenance. This is a preventive maintenance based on equipment status. Monitoring system is widely used in design and advanced diagnostic technology is used in maintenance.
According to the information provided by status monitoring and diagnostic technology Judge the abnormality of the equipment, predict the equipment failure, and carry out appropriate maintenance before the failure occurs. Due to the timely grasp of the maintenance opportunity, this maintenance method can make full use of the service life of equipment parts and avoid over repair and under repair. It is the most reasonable maintenance method, which is suitable for key and key equipment such as CNC machine tools.
