How to deal with the malfunction of the vertical machining center

The various phenomena exhibited by a vertical machining center machine when it malfunctions. If a malfunction occurs, check for sparks, bright light, abnormal noise, heating in the position, and a burnt smell. Carefully observe the surface condition of each printed circuit board that may malfunction, check for signs of burning or damage, and narrow down the inspection scope. This is a basic and commonly used inspection method.

Self diagnostic function of horizontal machining center machine: relying on the ability to quickly process data, multiple and fast signal acquisition and processing are carried out on the erroneous parts. The diagnostic program performs logical analysis and judgment to determine whether there is a fault in the system and locate the fault location in a timely manner.

The self diagnostic function of modern systems can be divided into the following two categories:

Power on self diagnosis: From each power on to the preparation state for normal operation, the internal diagnostic program of the system automatically performs functional tests on modules such as CPU, memory, bus, I/O unit, printed circuit board, CRT unit, photoelectric reader, floppy disk drive, etc. before operation, to confirm whether the main hardware of the system can work normally.

Fault message prompt: When the machining center malfunctions during operation, the number and content will be displayed on the CRT monitor. According to the prompts, refer to the relevant maintenance manual to confirm the cause of the malfunction and the troubleshooting method.

Generally speaking, the richer the fault information prompted by the diagnostic function of horizontal machining centers, the more convenient it will be for fault diagnosis. However, it should be noted that the cause of some faults can be directly confirmed based on the fault content prompts and by referring to the manual; The true cause of some faults does not match the fault content prompt, or multiple fault causes are displayed for one fault, which requires maintenance personnel to find the connection between them and indirectly confirm the specific cause of the machining center failure.
