The blocking station of the CB bond has been specifically designed for higher precision in manual alloy blocking creating an optimal environment for freeform and advanced Rx production.
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. A computer-controlled alloy filling station enables an uninterrupted and economical flow of alloy. Keeping the operator in mind, we designed the CB bond ergonomically to be run with ease and consistency.
