HMP-2AB Fully Automatic Metallographic Sample Grinding & Polishing Machine

Product Description

The HMP-2AB Fully Automatic Metallographic Sample Grinding & Polishing Machine integrates grinding, polishing, and sample preparation into a single automated system. Using a microprocessor-controlled touch-panel interface, the machine enables precise control of grinding speed, polishing head rotation, and pneumatic pressure. The dual-disc structure allows simultaneous processing of multiple specimens, significantly improving laboratory productivity.

Both grinding and polishing discs support stepless speed regulation from 100–1400 rpm, while the polishing head offers automatic pressure control, ensuring consistent and repeatable sample preparation results. Combined with its automatic water control, reverse/forward rotation modes, and robust 2.2 kW drive power, this machine is engineered for stability, durability, and long-term reliability.

Its automated specimen loading and central pneumatic pressure features minimize operator involvement, reduce human error, and help achieve uniform metallographic surfaces without deformation or overheating. The HMP-2AB is ideal for industrial production lines, university laboratories, metallographic analysis centers, and material research institutes requiring high-quality specimen preparation.
