Under normal circumstances, new CNC machine tools have been inspected before leaving the factory, so users often think that as long as the trial parts pass the inspection, the machine tool is deemed to have passed the inspection; the inspection of the accuracy of the machine tool is ignored.
Because the new CNC machine tool arrives at the site through the transportation link. Due to the vibration and deformation caused by transportation, the horizontal datum is completely different from the state at the time of factory inspection. At this time, the geometric accuracy of the machine tool deviates from the accuracy at the time of factory inspection.
Therefore, when inspecting a new CNC machine tool, it is not enough to only use the method of assessing the accuracy of trial machining parts to judge the overall quality of the machine tool, and use this as the only criterion for acceptance. The geometric accuracy, position accuracy and working accuracy of the machine tool must be measured. Comprehensive inspection, only in this way can the working quality of the machine tool be guaranteed.
