Trojan manual metallographic grinding and polishing machines include the single-disc Alpha-108 / 112 and dual-disc Alpha-208 / 210 / 212 series. Robust in design and compact in footprint, they offer multiple configurations with 8" / 10" / 12" disc options, stepless speed regulation from 50 to 600 rpm with reversible rotation, waterproof glass touch buttons or mechanical knobs, and 750–1,500 W high-power motors that deliver strong, reliable performance. The extra-large 12" working disc is ideal for large-sample preparation, and the series is suitable for metals, ceramics, glass, PCBs, and optical materials — with simple, intuitive, and durable operation.

Trojan automatic metallographic grinder polisher include Alpha-335G/P, Alpha-610 / 660, the VP-430 vibratory polisher, the WIT-1 intelligent preparation system, and the MultiPol fully automatic platform. The Alpha series integrate multi-point or central loading and controlled material removal, equipped with six dosing pumps and magnetic stirring to prevent sedimentation. The VP-430 eliminates surface stress, making it ideal for EBSD / AFM / SEM analysis. The WIT-1 employs CCD + AI technology to achieve 10 μm precision control, while the MultiPol delivers ultra-high reproducibility with fully standardized recipes — providing stable, repeatable sample preparation guarantees for material microanalysis.
