The basic blocking systems, CB Bond-E, and the full-fledged version, CB Bond, have been designed for higher precision in manual lens blocking with alloy.

High-resolution optical detection guarantees precise block/lens alignment. Unique CNC controlled prism and axis adjustment and the variable lens clamping position* ensure consistent results during long periods of operation. The after-clamping check monitors that every blocked lens meets the tight tolerance criteria needed for premium surfacing. And the auto-fill feature* enables a hands-free operation and consistent fillings.
