Weco E12

Breaking the rules again

The Weco E12 is an all-in-one patternless edging system that can satisfy all the core needs of a finishing lab. It offers drill, grooving, safety bevel, high luster polishing, and an advanced edging cycle to tackle difficult super hydrophobic lenses. Its most innovative feature is the new Gravitech® 3D Non-Contact tracing system, cutting the time to trace a lens to under 4 seconds! The addition of drilling makes the Weco E12 groove the right fit for your lab.

Lens Edging, Simplified

With an intuitive interface that guides you step-by-step in every phase of the process, lens finishing has never been easier.

See Every Detail with High-Definition Imaging

The Weco E12 integrates the best optical system on the market, allowing you to center your lenses in a fully parallax-free environment. See every lens marking and engraving, even ones you can‘t see with the naked eye with its high-definition camera system.

Tackle Rimless Eyewear Effortlessly

Gravitech® 2.0 is the most advanced tracing system in eyecare. It automatically detects drill holes, notches, and slots effortlessly with minimal adjustments, making the most difficult aspect of lens processing a breez.

Trace with Precision with Gravitech

Gravitech powered tracing enables you to easily trace a demo lens in under 4 seconds! It’s exceptional accuracy and precision produces results that are superior to a traditional mechanical tracer.

Block With Confidence with Gravitech

The  intuitive parallax-free , camera-assisted blocking system has been simplified to 3 easy steps that helps eliminate human error during the blocking process, decreasing the dreaded “redo” and increasing your patient satisfaction.
