Operating Procedures for Pipe Machining Equipment
Release time:
2026/03/25
The standard operating procedure for pipe processing machines covers six core steps: pre-startup preparation, workpiece clamping, parameter setup, test run, actual machining, and shutdown maintenance, ensuring machining accuracy and operational safety.
I. Comprehensive Pre-Startup Inspection
Environment and Equipment Condition: Confirm that the work area is clean and well-ventilated, that the equipment shows no signs of impact or deformation, and that there is no accumulation of metal shavings or oil residue on the guideways or worktable;
Lubrication System: Check that the hydraulic oil tank level is within the specified range, that the oil lines are unobstructed, and that moving parts such as guideways and lead screws have been lubricated with No. 46 anti-wear hydraulic oil;
Electrical System: Turn on the main power supply; verify that the voltage is stable, the emergency stop button resets normally, the CNC system displays no alarm messages, and parameter backups are complete;
Tool and Die Preparation: Select appropriate bending dies, clamping devices, and chains based on the pipe material, diameter, and wall thickness (e.g., DN1200 pipes require corresponding specifications), and inspect cutting components such as milling cutters and beveling tools to ensure they are in good condition.
II. Workpiece Clamping and Positioning
Place the pre-treated pipe (free of oil and burrs) steadily on the worktable, align it with the die reference line, and activate the clamping mechanism to ensure a secure hold, preventing slippage or deformation during machining. For large-diameter pipes, use the pipe quick-change assembly for rapid securing without the need for large lifting equipment.
III. Parameter Settings and Program Loading
Enter parameters such as bending radius, angle, and feed rate on the CNC panel, then load the preset machining program. Have two operators cross-check critical instructions such as G-code and spindle speed to prevent collisions or dimensional deviations.
IV.Dry Run and Test Machining
Select “Dry Run” mode and execute the first few segments of the program at low speed. Observe whether the tool path is normal and whether all axes move smoothly without abnormal noises. After confirming everything is correct, perform a test cut on the first piece to inspect dimensional accuracy and surface quality.
V. Formal Machining and Process Monitoring
Start automatic mode and closely monitor the machining status. The hydraulic system temperature must not exceed 60°C. If any abnormalities are detected, stop the machine immediately to investigate. After bending is complete, use a protractor and calipers to inspect the finished product, ensuring there are no defects such as cracks or wrinkles.
VI. Post-Operation Cleaning and Documentation
Upon completion of machining, turn off the power, clean up metal shavings and coolant, return tools to their designated positions, and fill out the equipment operation log to provide a basis for future maintenance.
