Frequently Asked Questions
-
Q: What is the difference between plain and grooved cerium oxide polishing pads?
A: Grooved pads have precision-cut channels across the surface that improve cerium oxide slurry flow during polishing, reducing heat buildup and preventing pad loading. Plain pads provide a larger uninterrupted polishing surface with maximum contact area — better suited for smaller workpieces and general lapidary polishing where slurry management is less critical.
-
Q: Which backing type should I choose — magnetic, PSA, or plain?
A: Choose magnetic backing for flat lap machines with magnetic quick-change plates (Genie, Titan, and similar systems). Choose PSA sticker for standard flat lap platens without magnetic systems. Choose plain (no backing) for hand lapping on glass plates or when using spray adhesive for custom mounting setups.
-
Q: What is cerium oxide lapping film used for compared to polyurethane pads?
A: Cerium oxide lapping film (0.3–0.5μm) delivers the finest, most controlled polishing action for optical-quality surfaces on glass, fiber optic connectors, and precision optical components. Polyurethane pads are better suited for general lapidary polishing, glass restoration, and applications where a softer, more conforming polishing surface is needed.
-
Q: Can cerium oxide pads be used on gemstones as well as glass?
A: Yes — cerium oxide polyurethane pads work well for final polishing of softer to medium-hard gemstones (Mohs 5–7) such as opal, turquoise, malachite, and fluorite. For harder gemstones (Mohs 7+) like agate, quartz, and sapphire, diamond compound on a tin or felt lap typically delivers faster and more effective final polishing.
-
Q: Do cerium oxide pads require additional compound, or are they ready to use?
A: The polyurethane pads are infused with cerium oxide and can be used with water alone for light polishing. For faster material removal or final mirror polishing, applying additional cerium oxide powder or slurry to the pad surface will significantly enhance polishing performance and speed.
