Basic requirements for CNC machine tool maintenance and service

Basic requirements for CNC machine tool maintenance and service


1. Improve the comprehensive quality of operators

The use of CNC machine tools is more difficult than the use of ordinary machine tools, because CNC machine tools are typical mechatronics products, which involve a wide range of knowledge, that is, the operator should have a wider professional knowledge of machine, electricity, liquid, gas, etc. ; Also, because the CNC system in its electrical control system is upgraded and updated relatively quickly, if you do not regularly participate in professional theoretical training, you will not be able to master the new CNC system application. Therefore, the quality requirements of the operators are very high. To this end, it is necessary to train CNC operators to make a more systematic study on the principles, performance, lubrication parts and methods of machine tools, and lay the foundation for better use of machine tools. At the same time, in the use and management of CNC machine tools, formulate a series of practical and effective measures.

Second, we must create a good environment for CNC machine tools

Because CNC machine tools contain a large number of electronic components, they are most afraid of direct sunlight, moisture, dust, vibration, etc. These can cause corrosion and deterioration of electronic components or cause short circuits between components, causing abnormal operation of the machine tool. For this reason, the use environment of CNC machine tools should be kept clean, dry, constant temperature and vibration-free; the power supply should be kept stable, generally only ± 10% fluctuations are allowed.

3. Strictly follow the correct operating procedures

No matter what type of CNC machine tool, it has its own set of operating procedures, which is not only one of the important measures to ensure the personal safety of the operator, but also an important measure to ensure the safety of the equipment and the quality of the products used. Therefore, the user must operate correctly according to the operating regulations. If the machine tool is used for the first time or if it has not been used for a long time, it should be idle for a few minutes; special attention should be paid to the order and precautions during startup and shutdown. The operation rules of various CNC machine tools are detailed in 6.5 below.

4. In use, increase the operating rate of CNC machine tools as much as possible

In use, it is necessary to increase the operating rate of CNC machine tools as much as possible. The newly purchased CNC machine tools should be put into use as soon as possible. The failure rate of the equipment in the initial stage of use is relatively large. Users should make full use of the machine tools during the warranty period to expose their weak links as soon as possible and solve them during the warranty period. If there is no production task, you can't use it idle, you should regularly turn on the power, run for about 1 hour each time, use the heat generated by the machine tool to remove or reduce the humidity in the machine.

Fifth, treat machine tool failures calmly and not blindly.

Some failures will inevitably occur during the use of the machine tool. At this time, the operator should treat it calmly and do not deal with it blindly, so as to avoid more serious consequences. It is necessary to keep the scene, and wait for the maintenance staff to explain the situation before and after the failure. Participate in joint analysis of problems and eliminate faults as soon as possible. If the fault is the cause of the operation, the operator should learn from the experience in time to avoid making the same mistake next time.

Sixth, formulate and strictly implement the rules and regulations of CNC machine tool management

In addition to the daily maintenance of CNC machine tools, it is also necessary to formulate and strictly implement the rules and regulations for the management of CNC machine tools. Mainly include: the "three fixed" system for appointing people, posts and responsibilities, regular inspection system, and standardized handover system. This is also the main content of CNC machine tool management, maintenance and maintenance.
