Manhart How to check the reliability of CNC bending machine?

When testing the reliability of a CNC bending machine, the following aspects can be considered and evaluated:
1、 Reliability testing of mechanical components
1. * * Clamping device * *:
-Check if the clamping device can firmly fix the workpiece to prevent it from sliding or falling off during the bending process.
-Observe whether the clamping device has obvious wear or damage to ensure that it can maintain stable clamping effect even after long-term use.
2. * * Stamping die and bottom die * *:
-Check the die and bottom die for wear, cracks, or other damages that may affect bending accuracy and workpiece quality.
-Check whether the fit between the die and the bottom die is tight and there is no gap to ensure that the required shape can be accurately formed during the bending process.
3. * * Transmission components * *:
-Check for wear or damage to transmission components such as gears, belts, chains, etc. Damage to these components may result in decreased equipment performance or frequent malfunctions.
-Check the lubrication of transmission components to ensure good lubrication, reduce friction and wear, and improve the reliability and service life of equipment.
2、 Reliability testing of electrical systems
1. * * Cable * *:
-Check whether the cable is damaged or aged, such as cracked outer skin, exposed internal wiring, etc. These damages may cause electrical faults or safety accidents.
-Regularly replace or repair cables to ensure the safe and stable operation of the electrical system.
2. * * Controller * *:
-Check if the controller is functioning properly and accurately controlling the actions and parameters of the equipment.
-Check whether the input and output interfaces of the controller are in good condition, and whether there is any looseness or poor contact.
3. * * Motor * *:
-Check whether the motor is damaged or aged, such as winding short circuits, bearing wear, etc. These damages may lead to a decrease in motor performance or frequent malfunctions.
-Regularly maintain and repair the motor, such as replacing lubricating oil, cleaning the heat sink, etc., to ensure the normal operation of the motor.
3、 Reliability testing of hydraulic systems
1. * * Hydraulic oil * *:
-Check whether the hydraulic oil is sufficient and clean, regularly replace the hydraulic oil to ensure the normal operation and bending accuracy of the hydraulic system.
-Observe the color and odor of the hydraulic oil, and replace it promptly if there are any abnormalities.
2. * * Hydraulic pump and hydraulic cylinder * *:
-Check whether the working status of the hydraulic pump and hydraulic cylinder is normal, such as whether there are leaks, abnormal noises, etc.
-Regularly clean and maintain hydraulic pumps and cylinders to ensure their long-term stable operation.
3. * * Hydraulic valve * *:
-Check whether each hydraulic valve is working properly, such as whether there is any jamming, leakage, or other phenomena.
-Regularly clean and debug hydraulic valves to ensure their normal operation and flow control.
4、 Comprehensive consideration of reliability assessment
1. * * Fault records and maintenance records * *:
-View the fault records and maintenance records of the equipment to understand the types of faults and maintenance status of the equipment.
-Analyze the cause of the malfunction and the effectiveness of the repair to evaluate the reliability and stability of the equipment.
2. Supplier qualifications and after-sales service:
-Consider the supplier’s qualifications and after-sales service quality, and understand their abilities and experience in equipment design, manufacturing, and maintenance.
-Choose suppliers with good reputation and after-sales service to improve the reliability and stability of equipment.
3. User reviews and word-of-mouth:
-Understand other users’ evaluations and usage of the brand or model of CNC bending machine.
-Evaluate the reliability and performance of the device based on user reviews and word-of-mouth.
Through the detection and evaluation of the above aspects, the reliability of the CNC bending machine can be comprehensively understood, and corresponding measures can be taken to improve its reliability and stability.
