5 FAQs of Polished 99 Alumina Ceramic Lapping Plate Ceramic Disc for Grinding

What exactly is this alumina ceramic lapping plate?
This is a super hard, flat disc made from 99% pure alumina ceramic. People use it to grind and polish other materials flat. It works like a super-accurate sanding surface. You put abrasive paste on it. Then you rub your workpiece against the plate.

Why pick alumina ceramic over other plate materials?
Alumina ceramic is incredibly tough. It resists wear much better than metal plates. This means it stays flat longer. You get consistent results over many uses. It saves money long-term. You replace it less often. It also handles harsh chemicals well.

How flat is this plate really?
The surface is polished super flat. We measure flatness very carefully. Expect flatness within a few microns over the whole surface. This precision is vital. It ensures your workpieces become perfectly flat too. Any unevenness ruins the final finish.

How do I actually use this plate?
First, clean the plate surface thoroughly. Apply a thin layer of diamond paste or other abrasive paste. Gently place your workpiece on the paste. Rub the workpiece in a figure-eight motion across the plate. Keep the pressure even. Add more paste as needed. The plate provides the flat reference surface.

How do I clean and care for the plate?
Clean it immediately after each use. Use water and a soft brush first. Then wipe it with isopropyl alcohol. This removes all abrasive paste residue. Never let paste dry hard on the surface. Avoid dropping it. Don’t hit it with hard objects. Store it flat in a safe place. Proper care keeps it accurate for years.
