PG‑1S Benchtop Single-disc Metallographic Specimen Polishing Machine

Product parameters:

The PG-1S is a compact, benchtop, single-disc metallographic specimen polishing machine. Weighing only 8.52 kg, it offers flexible placement and portability, making it ideal for laboratories with low-volume sample throughput. It is primarily designed for the fine grinding and mirror-finish polishing of metal specimens.
The unit features a 203 mm diameter polishing disc and a total power input of 400 W, operating on a single-phase 220 V AC (50 Hz) power supply. It supports continuous, stepless speed adjustment between 50 and 1,500 rpm and includes a reversible rotation function. Operators can freely adjust the disc speed based on specimen material, abrasive grit size, and specific polishing processes, effectively handling the grinding and polishing needs of various materials, such as steels and non-ferrous metals.

The machine comes standard with a water cooling system that continuously flushes the disc and specimen during operation. This effectively dissipates frictional heat—preventing thermal damage to the specimen's internal microstructure—while washing away grinding debris to keep the disc clean and ensure high-quality surface finishes. It features a digital display panel for clear, real-time monitoring of rotation speed, along with an intuitive control layout that ensures ease of use and simple maintenance.
With dimensions of 400 × 450 × 390 mm, the unit has a small footprint while balancing performance and practicality. It is widely suitable for university teaching laboratories, small-scale factory quality control, and research and development environments, serving as an economical and practical solution for metallographic sample preparation.
