**How to determine the types of faults in CNC bending machines**
CNC bending machine is one of the indispensable equipment in the modern metal processing industry, and its complex structure and system require operators to have the ability to judge and handle faults. This article will introduce how to determine the types of faults in CNC bending machines based on fault phenomena, including mechanical component faults, electrical system faults, software system problems, and hydraulic system problems.
1、 Mechanical component failure
1. * * Fault phenomenon**
-The bending machine experiences abnormal vibration or noise during operation.
-The bending accuracy decreases and the bending angle is not accurate.
-The mold or tool is severely worn and needs to be replaced.
-Loose or broken mechanical components.
2. * * Judgment method**
-Observe the operating status of the equipment and pay attention to the sources of vibration and noise.
-Check the machining quality of the bent parts and determine whether the bending accuracy meets the requirements.
-Check the wear of the mold and cutting tools, and replace them if necessary.
-Regular maintenance and upkeep of mechanical components, timely detection and resolution of issues.
2、 Electrical system malfunction
1. * * Fault phenomenon**
-The CNC system has no response or slow response.
-The motor cannot start or has abnormal speed.
-The display is abnormal, such as black screen, blurred screen, or garbled code.
-Electrical components generate heat, smoke, or emit a burnt odor.
2. * * Judgment method**
-Check the power supply, wiring, and connectors of the CNC system to ensure that the electrical system is powered normally.
-Check the operating status of the motor, such as current, voltage, and temperature, to determine if the motor is working properly.
-Check the display status of the monitor and try restarting the system or replacing the monitor.
-Pay attention to the working status of electrical components, such as heating, smoking, etc., and take timely measures to prevent accidents from occurring.
3、 Software system issues
1. * * Fault phenomenon**
-The CNC system program cannot be loaded or executed.
-The setting of processing parameters is incorrect, resulting in substandard processing quality.
-The CNC system displays error messages or prompts.
2. * * Judgment method**
-Check if the program files of the CNC system are complete, and try reloading or updating the program.
-Check if the setting of processing parameters is correct and make necessary adjustments.
-Carefully read the error messages or prompts of the CNC system, follow the prompts to operate or seek technical support.
4、 Hydraulic system issues
1. * * Fault phenomenon**
-Insufficient or unstable hydraulic system pressure.
-The hydraulic cylinder moves slowly or does not move.
-Hydraulic system leaks oil or produces bubbles.
2. * * Judgment method**
-Check the pressure gauge of the hydraulic system to determine if the system pressure is normal.
-Observe the movement of the hydraulic cylinder, such as speed, stroke, etc., to determine whether the hydraulic cylinder is working properly.
-Check the pipelines and connectors of the hydraulic system to ensure that there are no leaks or bubbles.
-Regularly maintain and upkeep the hydraulic system, clean the oil circuit, replace hydraulic oil, etc.
Summary:
Through the above introduction, we can preliminarily determine the type of fault based on the fault phenomenon of the CNC bending machine. In practical operation, we need to combine the equipment manual and technical support to further determine the specific cause and solution of the malfunction. At the same time, regular maintenance and upkeep of CNC bending machines, timely detection and resolution of potential problems, is an important measure to improve equipment reliability and stability.
