Hey I am new to the board.
I am a lab tech with a briot accura. it has all new wheels and groover. I have been having all kinds of issues with this machine but that is a whole other post.

Some of my semi rimless lenses have a white halo around the groove. it isn't doing it to all my lense and it doesn't seem to matter what material or rx the lens is or whether or not the lens is polished.

Any ideas as to what is going on or tips on fixing it?

Thanks!
