The U-groove dial optical sorting machine is specifically designed for the inspection and sorting of cylindrical components, including pins, shafts, rollers, and other items that cannot stand upright on a flat surface. The machine features a U-shaped groove along the edge of the glass dial, where products can lie securely for accurate inspection. This design prevents components from rolling or falling, ensuring stable placement and precise measurement.

The inspection speed varies depending on the material and the feeding system, ranging from 300 to 1000 parts per minute. It offers high inspection accuracy, achieving a precision of ±0.02 mm. The use of machine vision technology replaces manual inspection, significantly reducing error rates. Additionally, the system can be customized according to customer requirements, including adjustments to the inspection criteria and precision levels. This flexibility allows the machine to meet specific quality control needs across various industries.
