An optical lens edger is a machine designed to precisely shape the edges of optical lenses to ensure they have smooth contours and exact dimensions.
This machine features grinding wheels for shaping, fixtures to secure lenses, an automated control system, and systems for measurement and inspection. The grinding wheels, which are essential for the edging process, are coated with abrasive materials varying in type and grain size, tailored to suit different lens materials and desired finishes. Fixtures are used to firmly hold the lenses in accurate positions, providing stability throughout the edging process. The machine's automated control system, which is computer-operated, regulates the grinding speed, pressure, and adjustments to the position of the lens. Moreover, it incorporates sensors and cameras to continuously assess the quality of the grinding process and make real-time adjustments if necessary.
