lens edge and to the thickest place of lens edge in turns by pushing.
It is not available to get good shape of lens by standard
bevel edging because of level differences between
near point and far popint like Fig.18 in case of
(A)
(B)
(C)
EX Lens. FIG.17(A)
Therefore it is necessary to regulate the curves
voluntarily like Fig.17 (B),(C) and may be able to
get the curve of desired shape.
1) Choose conditions
Choose
2) Fix the lens to adaptor

3) Push and start edging
Screen is to be switched to simulation scree after measuring the thickness of
lens and then system is to be stopped.
Position section viewing line at the thickest place of lens.
Push
and switch to LENGTH by
and try to regulate with
or
Push
again and try to rotate
or
section viewing line
and check bevel position is off the track from lens.
Section viewing line is supposed to be stopped at the position off the track
automatically if bevel position is off the track.
Try again to get the desired shape by regualting RATIO or LENGTH and do over
RATIO 6.0 : 4.0
