Precision (Precision)-here mainly introduces the precision called machining, that is, the machining accuracy is within the range of 0.004-0.01mm.
In the past 10 years, the machining accuracy of ordinary CNC machine tools has been increased from 10μm to 5μm, and the precision machining center has increased from 3~5μm to 1~1.5μm, and the ultra-precision machining accuracy has begun to enter the nanometer level (0.01μm).
