Metallographic Grinding & Polishing Machine PC-20
Stable and easy‑operating single‑disk metallographic grinding and polishing machine with three fixed speeds, stepless adjustment, and durable engineering plastic body for reliable sample preparation.
The Metallographic Grinding & Polishing Machine PC-20 is a versatile single‑disk grinding and polishing device for laboratory metallographic sample preparation. It features a one‑piece environmental engineering plastic casing with a smooth surface, scratch resistance, and easy maintenance. The conical disc system enables fast disc replacement and cleaning. With stepless speed regulation and three customizable fixed speeds, the machine supports quick switching between grinding and polishing. Stable rotation, low noise, large‑diameter anti‑clogging drain pipe, and adjustable water flow ensure high efficiency and consistent sample quality.
