Manhart How to evaluate the equipment performance of CNC bending machines?

When evaluating the equipment performance of CNC downward bending machines, the following aspects can be considered:
1. * * Processing accuracy * *:
-Bending angle: Use an angle caliper to check whether the bending angle of the bent part meets the requirements. The deviation of the bending angle should be controlled within the range of negative deviation ∠ 0.5 ° to positive deviation ∠ 0.5 °.
-Bending straightness: Use a straight-line caliper to check the bending straightness of the bent part. Generally, the bending straightness is required to be ≤ 0.2% L (L is the length of the bent part).
-Bending size: Use tools such as calipers and rulers to check whether the size of the bent part meets the requirements. The deviation of the bending size should be controlled within ± 0.5mm.
2. * * Production efficiency * *:
-Processing speed: Evaluate the processing capacity of the equipment per unit time, such as the number of processes per hour, processing cycle, etc. This can be determined through actual production data or simulation testing.
-Automation level: Check the automation level of the equipment, including whether there is an automated loading and unloading system, and whether there is a highly automated CNC system. The higher the level of automation, the higher the production efficiency.
3. * * Stability and reliability * *:
-Operation stability: Observe the performance of the equipment during long-term operation to see if there are any abnormal noises, vibrations, overheating, or other phenomena.
-Failure rate: Counts the number and types of failures of equipment within a certain period, and evaluates the failure rate of the equipment. The lower the failure rate, the higher the stability and reliability of the equipment.
4. * * CNC system performance * *:
-Programming and operation: Evaluate whether the programming and operation of CNC systems are convenient and fast, and whether they support multiple programming languages and operation methods.
-Machining accuracy and efficiency: Check the control ability of the CNC system on machining accuracy and efficiency, including the accuracy of machining trajectory, stability of machining speed, etc.
5. * * Equipment maintenance and upkeep * *:
-Convenience of maintenance: Evaluate whether the maintenance and upkeep of the equipment is convenient, including whether it is easy to access the parts that need maintenance, whether detailed maintenance guidelines are provided, etc.
-Replacement and repair of accessories: Understand whether replacement and repair of equipment accessories are easy to carry out, as well as the time and cost required.
6. * * Security Performance * *:
-Protective devices: Check if the equipment is equipped with necessary protective devices, such as protective shields, protective doors, etc., to ensure the safety of operators.
-Emergency stop device: Evaluate whether the emergency stop device of the equipment is effective to ensure rapid shutdown in emergency situations.
Through comprehensive consideration of the above aspects, the equipment performance of the CNC downward bending machine can be comprehensively evaluated. In practical operation, corresponding evaluation standards and methods can be formulated based on specific situations to ensure the accuracy and reliability of the evaluation results.
