The initial use of CNC punch fault many reasons

From the CNC punch press machine installation and commissioning, start to run during the six months to a year, a higher frequency of failure, no general rules can be found.

From a mechanical point of view, in this period, even after the host running the trial production, but the machined surface of the part, there are still micro and macro geometry deviations before running completely, but also the surface is rough; member assembly form and position errors still exist, the use of CNC punch at the beginning of the run may cause large wear, CNC punch member relative motion between the excessive clearance. Further, since the internal stress of the concrete foundation of new and yet stable equilibrium, so that the machine also have some dispersion in the accuracy. From an electrical point of view, and the CNC machine control system performs a large number of electronic components of power devices, these devices and components at the manufacturing plant and even after rigorous screening test machine processing machine, but in the actual operation, since the alternating load circuit and opening and closing transient shock "surge" current and a counter electromotive force or the like, so that some components can not afford the initial impact, due to current failure or breakdown voltage, resulting in failure of the entire apparatus. In general, during this period, electrical, hydraulic and pneumatic systems high failure rate, therefore, to strengthen the monitoring of machine tools, electromechanical machines regularly adjusted to ensure that the equipment in various operating parameters within specification.
