Nowadays, with lenses that come with super hydrophobic and slippery coating, it is very frustrating that the lens will slipped during edging, thus causing axis shift and shape out.
Chucking pressure has been adjusted to maximum value, anti slip sticker was used on both sides of lens, soft mode edging was set. But the slippage still happened. Any experts able to advise on how to prevent lens slippage during edging.
For your info, am using le9000 and le1000 edging machine.
Thanks in advance for any input on this issue
