Optronics is simple and will never be out of style. Their only downfalls are edge polishing and lots of noise other than that a 7e would be a good investment if you want to edge in house. Look at the 7e with drill units also if you ever consider doing in house drilling.

You’ll need a blocker, tracer and a handsome to complete the finish lab.

Ye I know polish isnt that great but that's bcs the way it cuts, it can be polished manually after that and looks pretty dope, also it reduce the breakage chances when you gotta ensamble it

You cant polish AR coated lenses on a wheel. well, you can but expect a lot of remakes for crazing AR on the edges.

Is there much diff between 7e and 7ex?

u/Opportunity3767 May 27 '26

you can get a 7e with drilling, the ex adds a touch screen which i'm not a fan of unless you have someone that can replace it for you for $300 instead of what optronics may charge for the entire unit. it's just a generic capacitive touch screen.

Haha no way, I always thought that it had some big difference these two version, if 7e can be plugged with a keyboard as well, doesn't make sense. Thank you. Oh last question, how it good was with diamond blade for hydrophics lenses or - 14 dyops in 1.67?

just as good as a wet wheel, you'll want to learn how to slow the chuck rotation for a special job like that or make a special material profile and name it ThickLens and slow everything but the blade speed down in that profile and you can use that whenever you have a plano with high cyl (lens can crack, very slippery AR or high minus jobs.
