Lens axis off (turing) on high in-dex with ARC. Edger machine recommendation?

[Glacier Optical]

Hi all, hope everyone has a wonderful day.
We are currently using Horizon II dry edger machine. We constantly has issue with lens turning during edging process. We even tried Hydrophobic lens stickers to no avail. This problem is especially severe when it comes to those Kodak Total blue lenses with ARC.

Would getting a wet edger instead of dry edger help solving this issue?

We are currently looking at Coburn Technologies wet edger. HPE-410 and HPE-910. Which one is better? Any pros and cons? Would like to hear everyone's experience on these machines. Also in consideration is National Optronics's 7EX Edger.

Again, thanks in advance.

The slipping issue is probably attributed to the fed rate of the edger. I ran a Horizon II back in the day and setting fed rate to 1 didn't help with large blanks with AR as it would run into cutting blade on first rotation.

I'd recommend the 7E. I prefer dry cutting as this edger has multiple cutting setting variations for various lens types.
