The correct use of CNC equipment is the key to reducing equipment failure and extending service life. According to statistics, one-third of the faults are caused by humans, and general maintenance is performed by the operator. Therefore, it is necessary to enhance the awareness of equipment management, use and maintenance of operators, strengthen business and technical training, improve the quality of personnel, enable them to master the performance of machine tools as soon as possible, strictly implement equipment operating procedures and maintenance procedures to ensure the normal operation of equipment. To train qualified operators and maintenance workers to use CNC equipment, we should select workers who are quick-thinking, ambitious, mastered in mechanical processing technology and certain numerical control knowledge, and have rich experience in equipment failure judgment and on-site practical experience. The operation of the machine tool, especially the selection of the machining center operator, is more stringent. It is necessary for the operator to strengthen technical education and quality education so that they can both operate the equipment safely and carefully and maintain the equipment. Before going to work, you must carry out technical knowledge, operational ability and maintenance knowledge examination. Those who have passed the operation permit can operate the equipment independently. In order to maintain the numerical control equipment, through various forms and various channels, the modern CNC equipment management knowledge and maintenance technology are popularized, so that the maintenance personnel's business level is continuously improved, and the maintenance backbone is cultivated and created in practice. According to the characteristics of numerical control equipment and the actual situation of a certain factory, the management system of Jiankou's balance, rationality and maintenance is gradually established. (1) Make detailed and put forward higher requirements on the basis of the numerical control equipment management system; especially put forward special operation and maintenance requirements for the control system, such as: operation and maintenance, do not arbitrarily change machine parameters, call disk program or new The knitting program should be carefully checked, and then the dry running test should be carried out. The device-specific disk must be kept in a safe place to prevent program loss and virus infection. (2) The numerical control equipment operating procedures and maintenance procedures are formulated for 23 different types of numerical control equipment in a factory. According to the different structures, movement characteristics and control modes of different models, the basic rules such as the items, procedures and actions that the equipment operators must follow are to guide the operators to correctly grasp the operation skills and ensure that the operators and maintenance personnel carefully maintain the equipment. Technical specifications to ensure normal operation of the equipment, reduce malfunctions and prevent accidents. (3) The regular maintenance system of numerical control equipment is a specific implementation specification based on the different requirements and general requirements of different numerical control equipment for maintenance. The clear work content and maintenance responsibility of the operator and maintenance workers are specified. “Check card†is established by determining specific checkpoints for different equipment, requiring operators to perform daily lubrication, air pressure, hydraulic and cooling systems, as well as equipment operating sounds, NC systems, limits and safety devices. The items are inspected and recorded on the card according to the prescribed symbols. This can detect early signs of failure and hidden dangers, prevent sudden failures, and change the traditional after-the-fact maintenance to predict maintenance. (4) The CNC equipment inspection system is an important part of on-site management. It clarifies the operation, maintenance and equipment inspection and handover responsibility of the operator; clarifies the responsibility of the maintenance personnel for inspection and inspection; the management of the mobile department regularly or irregularly visits the on-site inspection and supervision system, and implements equipment management. Go to the site, check the equipment to the site, and deal with equipment problems to the site. Because of the system and feasible equipment on-site management specifications, the site management has rules to follow and is well documented. With a sound management system, the assessment has indicators and supervision has a basis, which improves the maintenance quality of the equipment, so that the numerical control equipment can always be in a normal controlled state, and the normal operation of the equipment is reliably guaranteed.
