MP-2B Metallographic Specimen Grinding and Polishing Machine

The MP-2B metallographic sample grinding and polishing machine is a variable-frequency, stepless speed-adjustable dual-disk benchtop unit, designed for pre-grinding, grinding, and polishing operations of metallographic samples. The left disk serves as the pre-grinding disk, while the right disk functions as the polishing disk. This machine not only allows for light grinding, rough grinding, semi-finish grinding, and finish grinding of samples but also enables precision polishing. It is an indispensable piece of equipment for users preparing metallographic samples.

Cooling System

This machine is equipped with a cooling device that can cool the specimen during grinding and polishing to prevent damage to the metallographic structure caused by overheating.

Control system

This machine uses a frequency converter for speed regulation, allowing it to directly achieve speeds between 50 and 1000 revolutions per minute.
