What should be noted during the operation of CNC machine tools?

During the operation of CNC machine tools, it is necessary to strictly follow the norms throughout the entire process, from safety protection, startup preparation, processing operation to shutdown maintenance, in order to ensure personal safety, equipment stability and processing accuracy.

️ basic safety protection requirements

Dress code ‌ : Work clothes and protective glasses must be worn. It is strictly prohibited to wear gloves, ties, sandals or high heels on duty. Long hair must be completely tucked into the work cap.

Environmental requirements ‌ : No obstacles should be piled up around the machine tool to ensure sufficient operating space. It is strictly prohibited to directly clean the machine tool, electrical cabinet and NC unit with compressed air.

Qualification requirements ‌ : Operators must pass systematic training and assessment, be familiar with the structure, performance and operation panel functions of the machine tool, and are not allowed to start the machine tool without permission.

⚙️ key points to prepare before startup

Status check ‌ : Before starting up, check that the oil level at each lubrication point is sufficient, that the guide rails and sliding surfaces are free of iron filings and impurities, that the safety protection and braking devices are complete and in good condition, and that the electrical grounding is reliable.

startup process ‌ : First, connect the main power supply of the machine tool. After starting the system, ‌ must first perform the operation of returning each coordinate axis to the reference point ‌ to establish the correct machine tool coordinate system.

Workpiece and tool preparation ‌ : Select suitable fixtures to firmly hold the workpiece. The tool specifications should match the machine tool requirements. Severely damaged tools must be replaced in a timely manner. Ensure that the tool and workpiece are not loose.

Program verification ‌ : The processing program must be strictly inspected in advance to check the code format, cutting parameters, tool compensation values and workpiece origin Settings. Run the machine idle to confirm that the path is correct.

processing operation specifications

Protection requirements ‌ : Before starting the spindle for cutting, the machine tool protection door must be closed properly. During the program operation, the protection door must not be opened at will. The electrical cabinet door must not be opened during normal operation.

Operation control ‌ : The operation panel buttons should be triggered only after confirming that they are correct. Blind operation is strictly prohibited. When the machine tool is in operation, no part of the body shall enter the travel range of the moving parts. It is strictly prohibited to pass objects across the machine tool.

Processing control ‌ : Set the feed rate and spindle speed strictly in accordance with the process requirements. Do not use the equipment beyond the specifications or overload. Do not use blunt tools or force processing with excessive cutting depth.

Abnormal handling ‌ : If any abnormality such as vibration, unusual noise or strange smell occurs during processing, immediately press the emergency stop button, preserve the accident scene, stop the machine to troubleshoot and then resume operation. After an emergency shutdown and restart, the zero return operation of each axis must be completed again.

Leaving post requirements ‌ : During the operation of the machine tool, the operator is strictly prohibited from leaving the post without permission. If it is necessary to leave, the machine must be stopped and the power supply turned off.

shutdown and daily maintenance requirements

shutdown process ‌ : After processing is completed, stop the spindle first, then move all operation handles and switches to the non-working position. Turn off the power of the operation panel, the main power of the machine tool, and the air source in sequence.

Cleaning and maintenance ‌ : Clean the iron filings and oil stains on the workbench and guide rail surfaces in a timely manner. It is strictly forbidden to wipe the guide rails with dirty cotton yarn containing iron filings to avoid scratching the sliding surfaces. Lubricate and maintain each lubrication point as required.

Long-term idle management ‌ : When the machine tool is not in use for a long time, it should be powered on 1-2 times a week, and run idle for 1 hour each time. The heat generated by the equipment itself can reduce the internal humidity, preventing electronic components from getting damp and system parameters from being lost.

Record archiving ‌ : Record in detail the operating status of the equipment and the faults found. For faults that cannot be repaired by oneself, report for repair in a timely manner.
