**How to ensure personnel safety during maintenance of CNC circular machines**
1、 * * Professional training**
The primary measure to ensure personnel safety in the maintenance work of CNC circular machines is to provide professional training. Maintenance personnel must receive training on equipment structure, working principles, safety operating procedures, and emergency response. The training content should include but not be limited to basic knowledge and maintenance skills of machine tool electrical, mechanical, hydraulic, pneumatic and other systems, as well as safety operation standards, accident prevention and emergency response measures. Through professional training, maintenance personnel can better understand the operational risks of equipment, thereby effectively preventing accidents from occurring.
2、 * * Personal protection**
During the maintenance process, maintenance personnel must wear appropriate personal protective equipment, such as safety helmets, protective goggles, earplugs, gloves, protective clothing, etc. These protective equipment can reduce injuries caused by accidental splashes, noise, electric shocks, etc. during the maintenance process. In addition, maintenance personnel need to pay special attention to the implementation of protective measures when coming into contact with chemicals, sharp objects, or high-temperature objects.
3、 * * Equipment inspection**
Before carrying out maintenance, maintenance personnel need to conduct a comprehensive inspection of the CNC circular machine to understand the current operating status and existing problems of the equipment. Through inspection, safety hazards of equipment can be identified and dealt with in a timely manner, avoiding safety accidents caused by equipment failures. During the inspection process, maintenance personnel should pay special attention to the safety performance of electrical systems, mechanical systems, hydraulic systems, pneumatic systems, etc., to ensure that the equipment is in good working condition.
4、 * * Standardized operation**
During the maintenance process, maintenance personnel must strictly follow the safety operating procedures and operate according to the prescribed steps and methods. It is strictly prohibited to engage in illegal operations, rough construction, and other behaviors. During key stages such as disassembly, installation, and debugging, maintenance personnel need to pay special attention to safety operation requirements to ensure personal safety. In addition, maintenance personnel should also understand the usage methods of safety facilities such as emergency stop devices and alarm devices of the equipment, so as to quickly take measures in emergency situations.
5、 * * Safety signs**
At the maintenance site, obvious safety signs should be set up, such as “no closing”, “no touching”, “pay attention to high temperature”, etc. These safety signs can remind maintenance personnel to pay attention to safety precautions and avoid accidental operation or touching hazardous areas. At the same time, the maintenance site should also be kept clean and orderly, avoiding phenomena such as debris stacking and cable dragging to ensure personnel safety.
6、 * * Security tools**
During the maintenance process, using safety tools is one of the important measures to ensure personnel safety. Maintenance personnel should use specialized tools that meet standards, such as torque wrenches, multimeters, insulated gloves, etc. It is strictly prohibited to use unqualified or damaged tools to avoid safety accidents caused by tool reasons. In addition, maintenance personnel also need to understand the correct use of tools to avoid injuries caused by improper operation.
7、 * * Reporting of hidden dangers**
During the maintenance process, if safety hazards or abnormal situations are found in the equipment, maintenance personnel should promptly report to the relevant person in charge. The reported content includes the specific situation of hidden dangers, possible impacts, and suggested handling measures. By timely reporting hidden dangers, relevant departments can be prompted to take measures for rectification and handling, thereby eliminating safety hazards and ensuring personnel safety.
8、 * * Accident handling**
When a safety accident occurs, maintenance personnel should quickly take measures for emergency handling, such as cutting off the power supply, turning off the air source, etc. At the same time, it is necessary to promptly report the accident situation to superiors and actively participate in accident investigation and handling work. During the accident handling process, maintenance personnel should summarize their experience and lessons, identify the cause of the accident, and propose improvement measures to prevent similar accidents from happening again.
In summary, ensuring personnel safety is a crucial task in the maintenance of CNC circular machines. The comprehensive application of professional training, personal protection, equipment inspection, standardized operation, safety labeling, safety tools, hidden danger reporting, and accident handling measures can significantly reduce the incidence of safety accidents and ensure the safety of maintenance personnel.
