Product name
Automatic Metallographic Grinding and Polishing Machine MoPao® 2S.

Overview
The MoPao® 2S is a dual‑platen benchtop automatic grinding and polishing machine designed for high‑precision metallographic sample preparation. It integrates a microprocessor control system with stepless speed regulation for both the grinding/polishing disc and the polishing head, and provides intuitive settings for load and process time. Quick replacement of discs, abrasive papers and polishing cloths enables rapid workflow changes and broad application versatility.
