Using your Edger...Points to remember
Safety-bevel
Maximum depth = 0.6 mm in steps of 0.1 mm
Retouching with safety-bevel is possible if the value of the retouch is less than
0.2 mm (at Boxing width)
Minimum distance between the apex of the bevel and the front/rear face to
produce a safety-bevel = 1.6 mm
Min. distance between the front face of the lens and the front edge of
the groove (or rear face and rear edge) to make a safety-bevel = 0.4 mm
Accuracy of the edger
Dimensional accuracy = +/- 0.06 mm at diameter
Axis setting accuracy = +/- 0.5° per lens (entry+blocking+edging).
