This efficient automatic blocker, designed for higher volume applications, is a “hands off” unit, which eliminates operator variability.

  • Wax/pitch dispensing is precision-controlled, as is wax thickness. The compound is continuously mixed to keep it homogenous, ensuring an accurate, repeatable pitch/wax application.
  • The innovative technology is based on safety and repeatability, so the blocker automatically closes the collet and seats the blank, with a safety interlock for operation.
  • The blocker, with four alignment axes, is designed to deliver long-term precision for spherical and prism lenses.
  • It can be used as a prism blocker with cylinder axis layout, and it easily adjusts for button tilt and radial run-out.
    It requires only a single calibration at setup.
  • The smart air-actuated, pressure-controlled collet automatically adjusts to any standard 1/2 blank at consistent pressure without warping or crimping the lens.
  • The dead-length-stop provides precise thickness for high volume production
  • A digital gauge measures to .001 mm with uninterrupted memory.
  • The durable cast iron construction assures stability of operation.
  • Custom models are also available.
