Safety precautions for CNC machine tools

1、Pre-Operation Preparation

Machine Inspection: 

Thoroughly inspect the power supply, cooling system, lubrication system, and transmission system to ensure all components are functioning properly. 

Also, confirm that the tool, fixture, and workpiece are correctly installed and securely fastened.

Program Verification: 

Run the machining program in a simulated environment to check for collisions, overtravel, and other issues.

 Adjust the program promptly to avoid problems during actual machining.

Safety Precautions: Operators must wear protective equipment such as safety glasses and must not wear gloves when operating the lathe. 

Clear debris around the machine and keep a clear path.

2、Precautions During Operation

Follow operating procedures: 

Strictly follow the procedure flow. Do not arbitrarily change parameters or skip steps. Do not open the electrical cabinet while the machine is running. 

Do not press the "Emergency Stop" and "Reset" buttons at will. If a malfunction occurs, remain on site and report it promptly.

Set parameters appropriately: 

Optimize cutting speeds, feed rates, and other parameters based on the workpiece material, tool type, and machining requirements. 

Regularly check tool wear and  ｒｅｐｌａｃｅ worn tools promptly to ensure machining accuracy.

Monitor machining in real time: 

Closely monitor the machine's operating status. Sensors and monitoring systems can be used to monitor tool wear, workpiece dimensions, cutting forces, 

and other parameters in real time. 

If any abnormality is detected, stop the machine immediately for inspection, such as adjusting machining parameters or replacing tools.

3、Post-Operation Precautions

Cleaning and Maintenance: 

After machining, promptly remove chips, wipe the machine, and keep the machine surface and interior clean. 

Turn off the power switch and main power switch on the machine operator panel in the prescribed order, reset all function keys, lubricate the machine, 

and apply anti-rust oil to the work surface.

Tool Management: 

Remove tools from the tool magazine, add anti-rust oil, and number them for easy identification the next time they are used, thereby extending tool life.

Recording and Feedback: 

Record machine operating conditions, any problems encountered during machining, and other information to provide reference for subsequent machining 

and machine maintenance. 

If any potential machine faults or abnormalities are discovered, promptly report them to the relevant maintenance personnel.

In addition to this, operators must receive professional training to master CNC machine tool operating skills and safety knowledge. 

They must also strictly adhere to safety operating procedures and avoid overloading, exceeding performance limits, or operating machines beyond specifications, 

ensuring the safe, stable, and efficient operation of CNC machine tools.

CNC machine tools are critical equipment in modern manufacturing. Proper operation is crucial for ensuring machining quality, improving production efficiency, 

and ensuring the safety of personnel and equipment.
