Introduction
The CNC machine is a kind of automation equipment which is widely used in modern machinery manufacturing. Its working principle is to use a computer to process a program, use the numerical control controller to read the program signals, realize the corresponding mechanical actions, and drive the machine actions such as drilling, cutting and milling according to the program. The CNC machine usually has a higher positioning accuracy and a more complex processing technology than ordinary machine tools.
Common electrical faults of CNC machine tools can be divided into five categories:1. Software fault 2. Mechanical fault 3. Hardware fault 4. Power supply fault 5. Machine operator fault.
Software Fault
Software faults of CNC machine tools are generally caused by programming errors, faulty instructions and operation wrong instructions of CNC software. This type of failure mainly includes errors in the programming language, programming parameters, program data and other software errors.
Mechanical fault
Mechanical failure is caused by the wear and tear of some parts or components of the CNC machine, or incorrect installation of the CNC parts. Mechanical failures are mainly caused by improper installation and use of the machine, resulting in excessive vibration, abnormal sound and bearing heating of the machine.
Hardware Fault
Hardware faults of CNC machine tools mainly refer to the malfunction or damage of hardware components, especially electronic components and electrical components, such as power module, servo module, encoder. This kind of failure is usually caused by some external factors, such as static electricity, lighting, and sudden current change.
Power supply fault
The power supply fault of CNC machine tools mainly refers to the occurrence of instantaneous overvoltage and voltage fluctuation, which affects the normal operation of the machine. In addition, the power failure of the machine will have a great impact on machine, resulting in the occurrence of breakdowns.
Operator Fault
The operator fault of CNC machines mainly refers to the improper operation of the operator, such as inputting wrong parameters, failure to monitor and adjust the amplitude of the process, failure to check and confirm the operation quality of the machine, and incorrect operation.
Conclusion
It is very important to understand the cause of CNC machine tool electrical faults and properly process them, which can ensure the smooth operation of the machine and reduce the downtime of the machine, improve production efficiency and reduce costs.
