**Common faults and countermeasures of twist axis CNC bending machine**
The torsion axis CNC bending machine, as an important equipment in modern sheet metal processing, plays a crucial role in ensuring product quality and improving production efficiency through stable operation. However, during use, due to various factors, there may inevitably be some malfunctions in the torsion axis CNC bending machine. This article will sort out common faults of twist axis CNC bending machines and propose corresponding countermeasures to help operators better troubleshoot and maintain them.
1、 Oil pump startup issue
The oil pump is the core component of the hydraulic system of the twist axis CNC bending machine. If the oil pump cannot start normally, the entire machine will not work. The problem of starting the oil pump is usually related to factors such as power supply, motor, oil level, and filter. The response measures include checking whether the power circuit is intact, whether the motor is working properly, whether the oil level is sufficient, and whether the filter is clean.
2、 Abnormal pressure fluctuations
Abnormal pressure fluctuation is one of the common hydraulic faults in torsion axis CNC bending machines, manifested as unstable system pressure, sometimes high and sometimes low. This may be caused by damage to the oil pump, malfunction of the relief valve, oil circuit leakage, or oil contamination. To solve such faults, it is necessary to investigate the possible causes one by one and make corresponding repairs or replacements.
3、 Excessive noise and vibration
If the noise and vibration generated during the operation of the torsion axis CNC bending machine exceed the normal range, it will not only affect the comfort of the operator, but may also cause damage to the equipment. The causes of excessive noise and vibration may include wear of guide rails, damage to bearings, and abnormal hydraulic systems. The response measures include checking and replacing worn guide rails and bearings, adjusting hydraulic system parameters, ensuring oil cleanliness, etc.
4、 Control issues with the filling valve
The filling valve is an important component of a torsion axis CNC bending machine, used to control the flow and pressure of hydraulic oil. If the filling valve malfunctions, it may cause abnormal movement of the slider or unstable system pressure. The methods to solve the control problem of the filling valve include checking whether the electrical control circuit of the filling valve is normal, cleaning or replacing the blocked filling valve, and adjusting the parameter settings of the filling valve.
5、 Abnormal slider movement
The slider is a key component of a twist axis CNC bending machine for executing bending actions. If the slider action is abnormal, it will directly affect the processing quality of the product. Abnormal slider movement may manifest as the slider being unable to lift, the lifting speed being too slow or too fast, or the slider position being inaccurate. These types of faults are usually related to hydraulic systems, electrical systems, or mechanical components, and require individual troubleshooting and repair of the relevant fault points.
6、 Servo communication failure
The torsion axis CNC bending machine adopts a servo control system to achieve high-precision positioning and motion control. If there is a malfunction in servo communication, it will cause the machine to be unable to work normally. Servo communication faults may manifest as unresponsive control systems, data loss, or transmission errors. The response measures include checking whether the communication line is intact, whether the communication protocol matches, and whether the servo drive is working properly.
7、 CNC system error
The CNC system is the core control system of a torsion axis CNC bending machine, responsible for parsing machining instructions and controlling the machine to perform corresponding actions. If there is an error in the CNC system, it will cause the machine to be unable to perform machining tasks correctly. CNC system errors may manifest as program errors, improper parameter settings, or system crashes. Solving such faults requires operators to have corresponding CNC programming and debugging abilities, and to troubleshoot and repair errors.
8、 Bending accuracy issue
Bending accuracy is one of the important indicators to measure the performance of a torsion axis CNC bending machine. If the bending accuracy does not meet the requirements, it will directly affect the quality and competitiveness of the product. The issue of bending accuracy may be caused by various factors, including mold wear, low positioning accuracy of the slider, unstable hydraulic system pressure, etc. The methods to solve the problem of bending accuracy include regularly replacing worn molds, adjusting the positioning accuracy of sliders, optimizing hydraulic system parameters, etc.
In summary, various faults may occur during the use of the torsion axis CNC bending machine. Operators need to be familiar with the common manifestations of faults and corresponding measures in order to conduct timely troubleshooting and maintenance. At the same time, it is necessary to strengthen the daily maintenance and inspection of equipment to ensure that it is in good working condition, improve production efficiency and product quality.
