Zinc Polishing Pad

Laps The Solid Zinc Polishing Lap has long been the preferred choice for professional gem cutters. Known for its durability and efficiency, Zinc Laps are harder than Tin and excel at producing Flat  facets quickly, even on the hardest colored stones. These versatile Laps are capable of delivering a high-quality polish on a wide range of stones, from the hardest to the softest, making them an essential tool for gemstone finishing.

One of the standout features of this Solid Zinc Polishin is its rigidity. Made from full-thickness Zinc alloy, it is robust enough to function as a single Solid Laps without the need for bonding to a base plate or requiring a Master Lap base. Additionally, it can be re-machined if necessary, ensuring long-term usability. These Laps are particularly favored for polishing harder gemstones such as corundum and cubic zirconia.

To prepare a new polishing disc, start by adding water and using 60-80# sandpaper. Polish from the outer edge inward until no scratches are visible, then repeat the process with 240# sandpaper. The same procedure applies when repairing an old disc. For optimal results, moisten the polishing powder with diamond oil to create a paste and continue polishing on 50-150# sandpaper. Ensure the disc maintains a certain level of humidity during the process. Apply the polishing powder evenly and polish until the surface turns black, indicating it is ready for use.

In summary, the Solid Zinc Polishing Lap is a durable, versatile, and efficient tool for achieving a high-quality finish on a wide range of gemstones. Its ease of use and ability to be re-machined make it a long-lasting investment for professional gem cutters.
