Other Data:


The manual dual disc grinding and polishing machine (P20G-2) is a specialized machine for metallographic specimen preparation. It is designed to meet the needs of laboratories or production lines with small quantities of samples and flexible preparation requirements, capable of grinding and polishing the sample surface to a mirror-like smoothness. This provides a convenient and high-quality solution for metallographic structure observation, analysis, material analysis, hardness testing of metal or other materials, and other needs.

P20G-2 comes with adjustable rotational speed functionality, allowing users to flexibly adjust the speed of the grinding discs based on different sample characteristics and preparation requirements to achieve the best preparation results. This flexibility ensures the precision and controllability of the preparation process, enabling each sample to achieve an ideal grinding and polishing effect. Moreover, P20G-2 is specially equipped with a low-speed grinding function, allowing users to perform more delicate and refined preparation processes.
