1.It performs mirror polishing on metal specimens to remove grinding marks and deformed layers from the specimen surface, achieving a scratch‑free, bright and smooth finish.
2.Working with metallographic sandpaper, polishing cloths and polishing agents (diamond polishing paste, alumina suspension, etc.), it completes the entire process from rough polishing to fine polishing.
3.It prepares specimens for metallographic microscopic observation; only after polishing can the internal metallographic structure of metals (grains, pearlite, ferrite, inclusions, etc.) be clearly displayed.
