Two: Relatively stable operation period

After experiencing the aging of various electrical components in the initial stage, the equipment begins to enter a relatively stable normal operation period after the grinding and adjustment of mechanical parts. At this time, the quality of various components is relatively rare, but does not rule out sporadic The occurrence of the fault, therefore, in this period, we must adhere to the equipment operation record, in case of troubleshooting. At the same time, we must insist on a comprehensive electromechanical test and check of the equipment every 6 months. During this period, the incidence of electromechanical failures was small and most could be ruled out. The relatively stable operation period is long, generally 7 to 10 years.

Three: end of life

After the machine tool enters the end of its life, all kinds of components begin to accelerate wear and aging, and the failure rate begins to increase year by year. The nature of the fault is gradual and organic. For example, the aging of rubber parts, the wear of bushings and hydraulic cylinders, the contact sensitivity of limit switches and the quality factors of some electronic components begin to decline, etc. Most of the gradual failures have regularity. Equipment operation records, most of the failures that can be eliminated. Since CNC punch presses are technology-intensive and knowledge-intensive devices, there are both conventional methods and means, as well as specialized techniques and testing methods. Fault diagnosis can often not be considered mechanically or electrically, but must be comprehensively analyzed.

    The above describes in detail the three deadlines for the use of CNC punch presses.
