CNC lathe manufacturers, CNC lathe circuit failure how to solve
There are circuit problems in CNC lathes. Check the overall structure of the electrical control system of the CNC lathe, the distribution of the motor and electrical components, and the control requirements.
1. Analysis of interlocks and protections Machine tools have high requirements for safety and reliability. To achieve these requirements, in addition to the rational selection of components and control schemes, a series of electrical protections and necessary controls are also set in the control circuit. Electrical interlocking.
2. Analysis of the auxiliary circuit The auxiliary circuit includes the power supply display, working status display, lighting and fault alarm, etc. Most of them are controlled by the components in the control circuit. In the analysis, the control circuit must be analyzed.
3. After the overall inspection has been reduced to zero and the working principle of each partial circuit has been analyzed step by step and the control relationships between the various parts have been performed, it is also necessary to perform a zero-to-zero method to check the entire control circuit to see if there are any omissions. It is necessary to further examine and understand the links between various control links from an overall perspective.
4, analysis of auxiliary circuits Auxiliary circuits including power display, working status display, lighting and fault alarm and other parts, most of them are controlled by the components in the control circuit, in the analysis, but also control circuit analysis.
5. Analyze the main circuit Start with the main circuit and analyze the control requirements of the electrical appliances based on the servo motor, auxiliary motor and solenoid valve, and analyze their control contents, including start-up, direction control, speed regulation and braking.
6. Analyze the control circuit According to the control requirements of the electrical circuits in the main circuit, each servo motor, auxiliary mechanism motor and solenoid valve, analyze their control content.
