Weco E52

Maximum flexibility for your lab The Weco E52 provides you with all the tools you need to achieve the best results in optical craftsmanship. From different bevel types and groove, to angular drilling, the E52 is the premier answer for modern frame fashions and maximum flexibility for your lab.

Highest accuracy in frame tracing

The CT46 combines the best available tracing methods. One innovative feature is the very smooth manual blocking system. The TrueScan tracing mechanism ensures extremely accurate
and reproducible results. Together with GraviTech technology, all types of frames will be traced with unparalleled precision.

Innovative stylus that can trace the toughest frames

The stylus technology allows precise binocular tracing of frames up to a base curve 9. By tilting, the stylus tip always touches the bottom of the frame groove, delivering perfect results even on asymmetric frame groove profiles.

Intelligent shape repair

The CT46 can accurately reconstruct broken or defective demo lenses with minimal effort.

Smart edging torque management system (TMS)

Weco E52 intelligently adjusts its edging cycles to the thickness of the lens and material. New sensors and improved software maintain constant pressure on the lens, thus reducing edging time with no risk of misalignment, especially on hydrophobic lenses.

Mini-bevel for precision fitting

In addition to standard bevel programs, there is also a manual bevel program available, which allows you to manipulate the bevel position at any point of the lens shape after the measuring cycle is performed. This allows full operator control of the bevel before edging.
