When the CNC rolling bending machine encounters problems during the processing, it can be quickly diagnosed and solved by following the steps below:
I. Problem diagnosis
1. **Observe the problem phenomenon**:
– Stop the machine immediately and carefully observe the specific manifestations of the problem, such as aluminum offset, inaccurate angle, abnormal machine noise, etc.
2. **Check processing parameters**:
– Verify whether the current processing parameter settings, such as bending speed, feed rate, roller pressure, etc., are consistent with the process requirements.
3. **Check system alarm**:
– Check the display screen of the CNC system to see if there is an alarm message, and understand the fault code or prompt.
4. **Hardware check**:
– Check whether the various parts of the machine are intact, whether the roller is worn or damaged, and whether the sensor is working properly.
II. Problem solving
1. **Adjust for specific problems**:
– **Aluminum offset**:
– Adjust the roller position to maximize its contact area with the plate.
– If necessary, replace the appropriate roller material or shape.
– **Inaccurate angle**:
– Recalibrate the machine angle measurement system.
– Adjust processing parameters to optimize the bending process.
– **Abnormal machine noise**:
– Check and tighten loose bolts and screws.
– Check whether the bearings and transmission parts are damaged and replace them in time.
2. **System parameter adjustment**:
– Adjust the relevant parameters of the CNC system, such as PID control parameters, servo drive parameters, etc. according to the actual situation.
3. **Cleaning and lubrication**:
– Clean the machine regularly to remove dust and impurities.
– Ensure that the lubrication system works properly and add or replace lubricating oil in time.
4. **Software update and adjustment**:
– Check the software version of the CNC system and update the software if necessary.
– Adjust or optimize the control program of the CNC system to adapt to different processing requirements.
5. **External interference troubleshooting**:
– Eliminate external interference factors, such as electromagnetic interference, vibration interference, etc.
III. Preventive measures
1. **Regular maintenance and inspection**:
– Develop and implement regular maintenance and inspection plans to ensure that the machine is always in good working condition.
2. **Training and operating specifications**:
– Strengthen the training of operators to improve their operating skills and troubleshooting capabilities of CNC roll bending machines.
– Formulate and implement strict operating specifications to reduce problems caused by improper operation.
3. **Spare parts preparation**:
– Prepare sufficient spare parts and wearing parts so that they can be quickly replaced in case of failure.
Through the implementation of the above steps, the problems encountered by the CNC roll bending machine during the processing can be quickly diagnosed and solved, and the normal operation of the equipment can be ensured. At the same time, strengthening the implementation of preventive measures can reduce the probability of failure and improve production efficiency and processing quality.
