“Detailed Explanation of Precautions for Using CNC Machine Tools”

As a key equipment in modern manufacturing, CNC machine tools play an important role in improving production efficiency and machining accuracy. However, in order to ensure the safe and stable operation of CNC machine tools and extend their service life, the following points should be noted during use.

I. Personnel Requirements

The operators and maintenance personnel of CNC machine tools must be professionals who master the corresponding machine tool expertise or those who have received technical training. CNC machine tools are high-precision and highly automated equipment. The operation and maintenance of them require certain professional knowledge and skills. Only personnel who have received professional training can correctly understand the working principle, operation method and maintenance requirements of the machine tool, so as to ensure the safe operation of the machine tool.Operators and maintenance personnel must operate the machine tool in accordance with safety operation procedures and safety operation regulations. Safety operation procedures and regulations are formulated to ensure the safety of personnel and the normal operation of equipment and must be strictly observed. Before operating the machine tool, one should be familiar with the location and function of the operation panel, control buttons and safety devices of the machine tool, and understand the processing range and processing capacity of the machine tool. During the operation process, attention should be paid to maintaining concentration to avoid misoperation and illegal operation.

II. Use of Electrical Cabinet Doors

Non-professionals are not allowed to open the electrical cabinet door. The electrical control system of the machine tool, including important components such as power supply, controller and driver, is installed in the electrical cabinet. Non-professionals opening the electrical cabinet door may come into contact with high-voltage electricity or misoperate electrical equipment, resulting in serious consequences such as electric shock and equipment damage.Before opening the electrical cabinet door, it must be confirmed that the main power switch of the machine tool has been turned off. When opening the electrical cabinet door for inspection or maintenance, the main power switch of the machine tool must be turned off first to ensure safety. Only professional maintenance personnel are allowed to open the electrical cabinet door for power-on inspection. They have professional electrical knowledge and skills and can correctly judge and handle electrical faults.

III. Parameter Modification

Except for some parameters that can be used and modified by users, users cannot modify other system parameters, spindle parameters, servo parameters, etc. privately. Various parameters of CNC machine tools are carefully debugged and optimized to ensure the performance and accuracy of the machine tool. Modifying these parameters privately may lead to unstable operation of the machine tool, decreased machining accuracy, and even damage to the machine tool and workpiece.After modifying the parameters, when performing a machining operation, the machine tool should be tested by locking the machine tool and using single program segments without installing tools and workpieces. After modifying the parameters, in order to ensure the normal operation of the machine tool, a test run should be carried out. During the test run, tools and workpieces should not be installed first, and the machine tool should be locked and single program segments should be used to detect and solve problems in time. Only after confirming that the machine tool is normal can the machine tool be officially used for machining.

IV. PLC Program

The PLC program of CNC machine tools is designed by the machine tool manufacturer according to the needs of the machine tool and does not need to be modified. The PLC program is an important part of the machine tool control system, which controls various actions and logical relationships of the machine tool. The machine tool manufacturer designs the PLC program according to the function and performance requirements of the machine tool. Generally, users do not need to modify it. Incorrect modification may lead to abnormal operation of the machine tool, damage to the machine tool and even harm to the operator.If it is really necessary to modify the PLC program, it should be carried out under the guidance of professionals. In some special cases, the PLC program may need to be modified. At this time, it should be carried out under the guidance of professionals to ensure the correctness and safety of the modification. Professionals have rich PLC programming experience and machine tool knowledge, and can correctly judge the necessity and feasibility of modification and take corresponding safety measures.

V. Continuous Operation Time

It is recommended that the continuous operation of CNC machine tools should not exceed 24 hours. During the continuous operation of CNC machine tools, the electrical system and some mechanical components will generate heat. If the continuous operation time is too long, the accumulated heat may exceed the bearing capacity of the equipment, thus affecting the service life of the equipment. In addition, long-term continuous operation may also lead to a decrease in the accuracy of the machine tool and affect the processing quality.Arrange production tasks reasonably to avoid long-term continuous operation. In order to extend the service life of CNC machine tools and ensure machining accuracy, production tasks should be arranged reasonably to avoid long-term continuous operation. Methods such as alternating use of multiple machine tools and regular shutdown maintenance can be adopted to reduce the continuous operation time of the machine tool.

VI. Operation of Connectors and Joints

For all connectors and joints of CNC machine tools, hot plugging and unplugging operations are not allowed. During the operation of CNC machine tools, connectors and joints may carry high-voltage electricity. If hot plugging and unplugging operations are performed, it may lead to serious consequences such as electric shock and equipment damage.Before operating connectors and joints, the main power switch of the machine tool must be turned off first. When it is necessary to unplug or plug in connectors or joints, the main power switch of the machine tool should be turned off first to ensure safety. During the operation, they should be handled with care to avoid damage to connectors and joints.

In conclusion, when using CNC machine tools, operating procedures and safety regulations must be strictly observed to ensure the safety of personnel and the normal operation of equipment. Operators and maintenance personnel should have professional knowledge and skills, conscientiously perform their duties, and do a good job in the operation, maintenance and upkeep of the machine tool. Only in this way can the advantages of CNC machine tools be fully exploited, production efficiency and machining quality be improved, and contributions be made to the development of enterprises.
