3.3.3.5 PRODUCE A MANUAL BEVEL
3.3.3.5.1 SITUATION
You wish to visualise the lens thickness and adjust the finishing position.
3.3.3.5.2 PROCEDURE
To produce a manual bevel:
1. Load or create a job.
2. Enter its characteristics.
3. Proceed as shown on the flow chart.
3.3.3.5.3 IMPORTANT NOTES
The maximum distance between the apex of the bevel and the front face is 5 mm.
If you wish to reposition the whole bevel, move the bevel apex in one direction to the required position.
Then do the same from the opposite point.
To make a safety-bevel of any type, the minimum distance between the bevel apex and the front/rear face
must be greater than 1.6 mm. If it is less than 1.6 mm at any point of the lens, the safety-bevel will not be
produced at this point.
3.3.3.5.4 LIMITS
If the maximum thickness of the lens is less than 2 mm, the applied bevel will automatically be of 50% type,
whichever type of bevel is selected initially.
3.3.3.5.5 RETOUCH
When the edging cycle is finished, remove the lens from the edging chamber without removing the block
so as to be able to retouch it if necessary.
Check the lens dimensions and finishing.
