Manhart How to ensure the processing accuracy of CNC rolling machines when processing metal sheets?

When CNC rolling machines process metal sheets, it is crucial to ensure the processing accuracy. Here are some key measures to ensure processing accuracy:
1. **Equipment selection and performance**:
– Choose a CNC rolling machine with high precision and stable performance. Ensuring the quality of the equipment itself is the basis for achieving the processing accuracy requirements.
– Pay attention to key indicators such as the brand, accuracy, and stability of the equipment, and choose products with quality assurance.
2. **Roller adjustment and calibration**:
– Accurately adjust the position and spacing of the rollers according to the thickness of the metal sheet and the required bending radius.
– Regularly calibrate the rollers to ensure that the parallelism and verticality between the rollers meet the processing requirements.
3. **Control system optimization**:
– Use industrial computers or special control systems to accurately control the movement and bending process of the rollers.
– Optimize programming technology to ensure that the input parameters are accurate and avoid processing deviations due to programming errors.
– Use high-precision position control and fine adjustment and calibration functions to reduce error accumulation and improve processing accuracy.
4. **Process parameter setting**:
– According to the material properties, thickness and bending requirements of the metal sheet, set appropriate process parameters, such as bending speed, bending force, etc.
– Strictly control the cutting parameters during the processing, such as cutting speed, feed speed, etc., to balance the processing efficiency and processing accuracy.
5. **Workpiece positioning and clamping**:
– Use high-precision fixtures and support structures to ensure the stability and accuracy of the workpiece during the processing.
– Use high-precision measuring equipment such as laser interferometers to measure the workpiece positioning and provide accurate data for workpiece positioning.
– Select appropriate fixtures and clamping force according to the processing conditions to avoid deformation or errors caused by improper clamping force.
6. **Temperature control**:
– Control the temperature of the machine tool itself, and use equipment such as refrigerators and heaters to maintain the stability and accuracy of the machine tool.
– Control the temperature of the cutting fluid to avoid errors caused by temperature changes.
– Temperature control of the workpiece and tool, such as using coolant to cool the tool to avoid errors caused by high temperature.
7. **Maintenance and care**:
– Regularly perform maintenance and care on the CNC roll bending machine, including cleaning, lubrication, tightening and other work.
– Regularly check the wear of key components such as rollers and guide rails, and replace severely worn components in time.
– Calibrate the equipment according to the specified time and requirements to ensure the accuracy and stability of the equipment.
8. **Operator skills**:
– Operators need to have professional skills and knowledge, and be proficient in the operation methods and programming techniques of CNC roll bending machines.
– Regularly conduct training and learning to improve the skills and safety awareness of operators.
Through the comprehensive application of the above measures, it can be ensured that the CNC roll bending machine can achieve a high processing accuracy when processing metal sheets. It should be noted that each specific processing project has its own specific requirements and challenges, so in actual operation, it needs to be adjusted and optimized according to the specific situation.
