CNC controlled alloy blocker

CNC-controlled alloy blocker with prismatic blocking. Offers unique features such as layout guided operator instructions, auto fill stop, and prism ring identification. 

The Layoutblocker-PRA (alloy) processes up to 120 lenses / hour. The system automatically adjusts prism angle, prism basis, and the axis of the blocking chuck. While one lens is cooling on the first station, another lens can be adjusted on the second station. 

Benefits and features

  • Easy to use with integrated layout system, the blocker automatically determines the lens position – lens marking is no longer necessary
  • Saves time and reduces errors with data transfer from host computer via barcode scanner
  • More efficient handling by parallel working on both stations
