P-1B Metallographic Sample Grinding and Polishing Machine (Single-Disc, Stepless Speed Control)

Description

Product Introduction:

During metallographic specimen preparation, grinding and polishing are indispensable steps; after these processes, the specimen achieves a mirror‑like, highly polished surface. The P‑1B metallographic grinder‑polisher employs a variable‑frequency drive, enabling stepless speed regulation of the grinding/polishing disc within the range of 100–1500 r/min. By switching between abrasive sandpapers and polishing cloths, both grinding and polishing can be performed, offering broad versatility. The housing is integrally molded by vacuum forming, presenting a modern aesthetic, while delivering smooth rotation, low noise, convenient operation, and high productivity. Equipped with a built‑in cooling system, it can cool the specimen during grinding and polishing, preventing overheating that might compromise the microstructure. This equipment is ideally suited for metallographic laboratories in factories, colleges, and research institutions, making it an outstanding choice for specimen grinding and polishing.

Features:

1. The housing is crafted from high-end, one-piece ABS molding, featuring a sleek, modern design that exudes sophistication and premium quality.

2. The cooling unit’s faucet is crafted from solid brass with a chrome-plated finish, offering excellent corrosion resistance (optional).

3. Stepless speed control, convenient and quick, meets a variety of needs.
