Breaking the rules again

For those looking for the perfect entry level with drilling for your finishing workshop you simply can’t do better than the Weco E.12

Gravitech®optical tracing

  • Superior tracing accuracy for shapes over a mechanical tracer
  • Factors in the base curve of the lens to recreate the complete 3d shape of the lens
  • Intuitive shape modification
  • Vast internal memory of 2,000 Jobs and 10,000 shapes
  • Automatically recognize drill points with minimal adjustment needed

Gravitech® blocking

  • Parallax free blocking on the gravity axis
  • High-definition camera system to analyze lens markings and engravings
  • Sturdy metal blocking army for increased reliability and precision

Gravitech® finishing

  • Edging on the gravity point of the lens ensures 1:1 shape reproduction of the lens
  • Fixed 10° grooving angle with adjustable depth and width
  • Front and back-side safety bevel on the lens
  • Fixed 10° drilling angle to cover the vast majority of drill jobs

Gravitech® fitting

  • Less retouches and more accurate sizing with Gravitech®
  • A superior fit and polish on a finished lens
  • Demo lens tracing prevents inaccurate trace results from frame distortion on thin metal eyewear
  • The demo lens trace represents the true shape needed to accurately fit in a frame
