Operating a CNC bending machine and its associated manipulator involves a series of precise steps to ensure accurate bending and smooth operation. This guide will walk you through the entire process, from setting up the power supply to programming and adjusting the machine for optimal performance.
Step-by-Step Guide to Operating a CNC Bending Machine and Manipulator
1. Power and Air Supply Connection
Confirm Connections:
- Ensure that both the power supply and air supply are properly connected.
- Check the pressure of the manipulator’s air pressure regulator, setting it between 0.4 MPa and 0.6 MPa.
2. Initial Setup of the Manipulator
Power On and Reset:
- Turn on the manipulator’s power and perform a home return action to reset the system.
Set Action Modes:
- Configure the action modes of the manipulator according to the specific requirements of the product.
Input Positions:
- Enter the standby and gripping positions for the manipulator based on the parameters indicated on the fixture’s label.
- Set the injection molding machine’s mold opening stroke according to the label parameters.
3. Inspection and Adjustment
Check Fixtures and Cylinders:
- Inspect for any abnormalities in the fixtures and cylinders, such as loose screws, damaged clips, irregular cylinder movement, air leaks, and suction cup condition.
Align Fixtures:
- Adjust all fixtures to be in the same vertical plane. If not aligned, adjust the stop screws on the connection block.
4. Semi-Automatic Adjustment
Micro-Adjust Gripping Position:
- Fine-tune the gripping position in semi-automatic mode and save the parameters after adjustments.
5. Setting Positions and Timers
Position Settings:
- Set the posture position, intermediate open position, and product release position for the manipulator.
Timer Module Configuration:
- Access the manipulator’s timer module to set the preliminary action times.
Injection Molding Machine Settings:
- Set the ejection pin delay to 2 seconds and the retraction delay to 5 seconds.
6. Full Automatic Operation
Automatic Mode:
- Operate the injection molding machine and manipulator in full automatic mode.
Monitor Operation:
- Carefully observe the equipment’s operation in automatic mode.
- Fine-tune the timings for both the manipulator and injection molding machine to achieve quick and stable responses.

Step-by-Step Guide to Operating a CNC Bending Machine
1. Programming the Machine
Input Parameters:
- Enter the necessary parameters such as bending angle, length, position, and sequence.
- Set the machine’s speed and pressure.
2. Material Placement and Machine Setup
Position Material:
- Place the material correctly on the machine.
Setup the Machine:
- Adjust the machine settings based on the material specifications and the desired bend.
3. Checking and Adjusting Bending Tools
Inspect Tools:
- Check the bending tools for any wear or damage and ensure they are properly aligned.
Adjust Tools:
- Make necessary adjustments to the bending tools to ensure accurate bending.
4. Starting the Bending Process
Initiate Bending:
- Start the bending process by pressing the foot pedal. The machine will begin bending the material.
Pause and Resume:
- Release the foot pedal to pause the bending process. Press it again to resume bending.
5. Monitoring and Quality Control
Monitor Machine:
- Closely observe the machine’s operation to ensure it is running smoothly.
Inspect Bends:
- Check the quality of the bends to ensure they meet the required specifications.
6. Post-Bending Inspection
Final Check:
- After the bending process is complete, thoroughly inspect the final product for accuracy and quality.
Troubleshooting Common Issues
1. Hydraulic Circuit Failures
Common Issues:
- Valve Blockages: Directional control valve or relief valve may get stuck.
- Electrical Faults: Valves may not receive power due to electrical issues.
Solutions:
- Clean Stuck Valves: Disassemble and clean the valves.
- Check Electrical Circuits: Inspect and repair any electrical faults.
2. Bending Machine Stalling
Possible Causes:
- Electrical Faults: Issues with the contactor or foot pedal switch.
- Solenoid Valve Problems: Lack of power to the solenoid valve.
Solutions:
- Inspect Electrical Components: Check the contactor and foot pedal switch.
- Clean Solenoid Valves: Disassemble, clean, and reassemble solenoid valves.
3. Y-Axis Setting Issues
Problem:
- Y-axis setting not moving up or down.
Solutions:
- Manual Valve Testing: Check each valve manually.
- Restart the Machine: Turn off the power, then restart the machine.
Ensuring Optimal Performance and Safety
Safety Precautions
Wear Protective Gear:
- Always wear safety glasses, gloves, and safety shoes.
Pre-Operation Checks:
- Inspect the motor, switches, wiring, and grounding.
- Ensure the work area and controls are correctly set.
- Check the alignment and fastening of the upper and lower dies.
Regular Maintenance
Monitor Operation:
- Continuously monitor the machine during operation for any anomalies.
- Stop the machine to make adjustments or corrections, never using hands during operation.
Preventive Maintenance:
- Follow the manufacturer’s maintenance schedule to keep the machine in optimal condition.
Conclusion
Operating a CNC bending machine and its manipulator requires careful attention to detail and adherence to safety protocols. By following the step-by-step guides for setup, programming, and troubleshooting, operators can ensure efficient and safe operations, leading to high-quality metalworking results. Always refer to the specific machine’s user manual for detailed instructions and consult the manufacturer for additional guidance.
