Metallographic sample grinding polishing machine Mopao 4

stepplatefor metalographic laboratories

Overview
The MoPao®4 automatic metallographic sample grinding and polishing machine is a next-generation, high-precision, fully automated sample preparation system designed for laboratory and production quality control. It integrates a microprocessor control unit with stepless speed adjustment for both the grinding/polishing disc and head, intuitive settings for pressure and time, and selectable rotation direction. Operators perform grinding and polishing operations by exchanging discs, metallographic abrasive papers and polishing cloths, enabling flexible workflows across material types.
