Causes of many failures in the initial use of CNC punching machines

       After the CNC punching machine was installed and debugged, it started to run for half a year to a year. The frequency of failures was relatively high, and generally irregularities were found. 

       From a mechanical point of view, during this period, although the main machine has undergone trial production run-in, due to the microscopic and macro geometrical deviations on the processed surface of the parts, theDEEP THROAT PRESS surface is still rough before the complete run-in; the parts are being assembled There are also shape and position errors, which may cause large running-in wear in the initial stage of use of the CNC punch, and cause excessive gaps between the relative moving parts of the CNC punch. In addition, because the internal stress of the new concrete foundation has not yet been balanced and stabilized, the machine tool also has certain accuracy deviations. From an electrical point of view, the control system and executive components of CNC machine tools use a large number of electronic DOUBLE POINT PRESS and electric devices. Although these components and devices have been strictly screened and processed by the whole machine in the manufacturing plant, in actual operation, due to alternating loads and circuits The instantaneous "surge" current of opening and closing and the impact of back electromotive force, etc., make some components unable to withstand the initial impact, and fail due to current or voltage breakdown, causing the entire PUNCHING AND FOLDING MACHINE PRESSequipment to malfunction. Generally speaking, during this period, the incidence of electrical, hydraulic and pneumatic system failures is relatively high. For this reason, it is necessary to strengthen the monitoring of the machine tool, and periodically adjust the machine tool to ensure that the various operating parameters of the equipment are within the technical specifications.
