Manhart How to evaluate the performance and stability of servo CNC bending machines?

When evaluating the performance and stability of servo CNC bending machines, the following aspects can be considered:
1、 Technical parameters
1. * * Bending capacity * *:
-Maximum pressure: measures the maximum force exerted by the bending machine on the material, usually selected based on the type, thickness, and length of the material.
-Maximum bending length and angle: Ensure that the machine can process the required length of workpiece and achieve the expected bending angle.
2. * * Control System * *:
-Stability and reliability: The control system should be able to operate stably, reducing faults and downtime.
-Functional richness: Check whether the system supports functions such as graphic programming, Chinese storage, and controllable jogs to meet different processing needs.
-Upgradability: Consider whether the system is easy to upgrade to meet the needs of future technological development.
3. * * Structural Design * *:
-Durable and Stable: Choose a structure with sturdy and stable characteristics to ensure the stability and accuracy of the machine tool during long-term operation.
-Floor area and operating space: Consider whether the size of the machine tool is suitable for the workshop environment and whether it is convenient to operate.
2、 Processing accuracy and efficiency
1. * * Straightness of bent workpieces * *: When checking the 5.9-meter workpiece, check if the straightness error is within 15 ‘to evaluate the machining quality.
2. * * Repetitive positioning accuracy * *: Check whether the repeated positioning accuracy of the bent workpiece is within the range of 3-5 threads to ensure machining accuracy.
3. * * Forming accuracy * *: Evaluate whether the 3-blade forming accuracy is within 18 threads, reflecting the processing ability of the bending machine.
3、 Safety performance
1. * * Safety protection device * *: Check if the machine tool is equipped with safety protection devices, such as emergency stop devices, protective covers, etc., to ensure safe operation.
2. * * Simplicity of operation * *: Evaluate whether the CNC system is intuitive and easy to understand, whether the operation is simple and convenient, and reduce the risk of misoperation.
4、 Manufacturer’s reputation and after-sales service
1. * * Manufacturer Qualification * *: Understand the manufacturer’s qualifications, technical strength, and market reputation, and choose a manufacturer with good reputation.
2. * * After sales service and technical support * *: Check whether the manufacturer’s after-sales service and technical support system is complete, to ensure that the equipment is maintained and serviced in a timely manner during use.
5、 Performance testing and data analysis
1. Performance testing: Evaluate the performance indicators of the servo system, including response time, steady-state error, overshoot, and static error, through methods such as gait testing, step testing, and sine testing.
2. * * Data Analysis * *: Analyze test data to understand system latency, bias, and overflow, in order to identify system strengths, weaknesses, and root causes of problems.
By considering the above factors comprehensively, the performance and stability of the servo CNC bending machine can be comprehensively evaluated. During the evaluation process, comparisons and choices can be made based on specific product models, technical specifications, and information provided by the manufacturer.
