Typical grinding and sub-aperture polishing of precision optics requires the work piece to be held with vacuum or an adhesive onto a metal or plastic blocking body. The adhesive may be a wax, pitch, epoxy, or UV cement. The UltraBloc is an ergonomic table-top device that allows for precision alignment when using an adhesive between your optics and blocking body. It incorporates a 0 to 20 rpm motorized precision bearing spindle, which can be activated via a foot switch or with a manual switch for continuous rotation. The blocking bodies are held with a precision hydraulic expansion chuck (with optional collets) or a v-block assembly to accommodate various diameter sizes. The operator has the option of vacuum assist through the center of the spindle, which is extremely helpful for small diameter optics. Horizontally mounted calipers and/or dial indicators assist in precise and repeatable alignment of lenses. The electronics and spindle assembly are totally enclosed, this unique configuration is actively air cooled to dissipate heat from pitch or wax blocking more efficiently. Using a torch or heat gun will not damage this robust unit. The UltraBlock is easy to clean and can also be utilized as a manual beveling station using diamond pads.
