OPT-380 automatic precision grinder and polisher has powerful comprehensive performance in the industry. It is mainly used for grinding and polishing sample preparation of metal, ceramic, glass, PCB board, optical materials (such as zinc sulfide, silicon and other crystals), refractory materials, composite materials and other materials. It is one of the ideal grinding and polishing equipment for scientific research and production experiments. The Φ380mm grinding and polishing disc can be used for grinding and polishing round pieces with diameter ≤ Φ142mm or rectangular planes with diagonal length ≤ 142mm.

MultiPol is a new generation fully automatic metallographic grinding and polishing sample preparation system from TROJAN, specially designed for high-load, high-reproducibility industrial sample preparation scenarios, providing stable sample preparation guarantee for material micro-analysis. The equipment adopts center loading and pressing technology, capable of quantitative grinding and precise control of grinding amount with accuracy up to 0.1mm; equipped with 6 groups of dosing systems to ensure sample preparation uniformity; compatible with 250mm-300mm diameter grinding discs to meet diversified sample preparation needs.

Use for the final polishing.
Non-crystallizing silica suspension with 10.5 PH, provides a chenical-mechanical polishing action for Titanium，Stainless Steel etc.

Polishing fluid Used for final polishing of tin, aluminum and other materials.

Non-agglomerated, gel alumina suspension. Ideal for polishing minerals, ferrous metals, carbides, precious metals, printed circuit board electronic components, and polymers, providing excellent results.

High-quality non-agglomerated alumina powder. Providing excellent surface finish. Suitable for PCBs, semiconductors, and most minerals and metals.

Water-base diamond suspension,loffering better polishing surface and faster polishing rate when using the same grit.

Water-based diamond suspension，used for polishing most materials.

Water-soluble, designed for coarse, fine, and ultra-fine polishing of non-water-sensitive materials when paired with polishing liquids.Reduces friction during polishing, prolonging the lifespan of polishing cloths.

Alcohol-soluble formula, suitable for water-sensitive materials in coarse, fine, and ultra-fine polishing processes. Reduces polishing cloth abrasion, extends service life of polishing cloths, and ensures thorough cleaning ease.

The Magnetic floppy plate is attached to the chassis of the grinder and can firmly adsorb various conversion plates (AD-PSA, AD-PB, AD-Foil Plate).

The AD-PB system is for Plainback abrasive SiC disc or diamond disc. lf the AD-PB transfer plate is dirty, just washing with water.
