How Accurate Is an Optical Sorting Machine?

      The inspection accuracy of an optical sorting machine is not a fixed value. It is determined by the optical hardware configuration, algorithm solution, and the characteristics of the parts being inspected, and can be flexibly matched to your product inspection requirements. Standard models can stably achieve an inspection accuracy of ±0.01 mm, which is sufficient for appearance defect and dimensional tolerance inspection of most precision hardware, plastic and rubber parts, fasteners, electronic components, and automotive parts.
For micron-level high-precision components, such as micro screws, precision probes, micro seals, and precision mobile phone structural parts, ultra-high accuracy up to ±0.001 mm can be achieved by upgrading to higher resolution industrial cameras and telecentric measuring lenses, paired with optimized coaxial lighting and sub-pixel detection algorithms, meeting the strict quality control requirements of high-end manufacturing.
      Inspection accuracy is also closely related to part size and defect type: the smaller the workpiece and the finer the inspection features, the higher the required optical magnification, and the higher the achievable inspection accuracy. The machine supports customized optical solutions on demand, and can be equipped with 1-50 sets of cameras with different magnifications simultaneously, balancing overall dimensional inspection and local high-precision detail inspection on a single machine.
      Compared with traditional manual visual inspection, machine vision inspection not only has a higher accuracy ceiling, but more importantly, delivers highly consistent and repeatable accuracy. Manual inspection can usually only distinguish differences above 0.05 mm, and performance fluctuates greatly due to fatigue, experience gaps, and emotional states. In contrast, optical sorting machines maintain the same accuracy standard stably 24/7, fundamentally avoiding customer complaints and quality losses caused by missed or false manual inspections.
