Zinc alloy pads are manufactured using special zinc alloys and are produced in various diameter metal pads. These pads may be applied to any type of curved surface, radial concave or protruding mould and using an emery compound liquid can grind a radial concave or protruding lens. Zinc alloy pads may also be used for flat glass grinding.Special point: 1 Convenience to use:The back of the Zinc alloy pad has a special adhesive.Remove the backing paper and stick the Zinc alloy pad to any mould when you use. 2, High grinding precision: The Zinc alloy pads have a standard thickness which guarantees a standard finish during the grinding processing. 3, Good grinding surface: Zinc alloy pads are manufactured from high quality pure alloy materials. Diamond powder is distributed evenly over the pad surface and the pad features water grooves to facilitate the grinding processing and these pads assure shorter grinding times with high precision resulting in a consistent high quality surface finish.
