(Summary description)Now NC equipment is used more and more widely, followed by how to ensure the effective utilization of the equipment. When the equipment fails, the equipment should be restored to normal use as soon as possible. In order to solve this problem, maintenance personnel should have high quality, not only rich professional knowledge, such as mechatronics technology, computer principle, NC technology, PLC technology Automatic control technology, driving principle, hydraulic technology, etc. in addition, they should master the general knowledge of machining and the simple programming of NC devices. In addition, they should have a certain level of English and be able to read English technical materials. They should have sufficient materials, including mechanical, electrical and hydraulic drawings, machine tool parameters, system operation and maintenance manual, PLC ladder diagram, etc           With the development of steel distribution industry and high-end sheet metal industry, users have higher requirements for the flatness of cross cutting uncoiling line fixed length shear strip, This trend is particularly obvious in the sheet uncoiling line. When determining the main parameters of the straightener, roll diameter and roll distance, it is necessary to meet not only the strength requirements of the straightening roll when straightening the maximum thickness strip, but also the straightening effect requirements of the minimum thickness strip, as well as the strength and journal strength of the universal coupling connecting the straightening roll         At present, the self diagnosis ability of CNC system is becoming stronger and stronger. Most faults of uncoiling line equipment can be diagnosed by CNC system and corresponding measures can be taken, such as shutdown. Generally, alarm display can be generated. When CNC equipment fails, sometimes alarm information is displayed on the display, and sometimes on the CNC device There will also be alarm indications on the PLC device and the driving device. At this time, these alarm information should be analyzed according to the manual. Some can directly confirm the fault cause according to the alarm information. As long as the contents of the alarm information are clear, the faults of NC equipment can be eliminated
