Key Applications & Uses

• Coarse to fine grinding of ferrous and non-ferrous metals, alloys, steels, cast irons, and tool steels in metallographic workflows
• Surface preparation of ceramics, composites, coatings, and hard materials for subsequent polishing and microscopic analysis
• Removal of mounting compounds, scale, decarburization layers, and deformation zones prior to fine polishing
• Batch grinding in quality control, failure analysis, and production testing laboratories handling moderate to high volumes
• Preparation of samples for microstructure examination, inclusion rating, grain size measurement, hardness testing, and weld evaluation
• Supporting university materials labs, research institutes, automotive/aerospace quality assurance, and industrial manufacturing requiring consistent, uniform abrasive performance

Frequently Asked Questions (FAQs)

Q: What is the difference between plain-back and PSA versions? A: Plain-back discs are economical and require a clamping ring or separate adhesive; PSA versions have built-in pressure-sensitive adhesive for quick, secure, ring-free mounting and easy removal.

Q: Which grit sequence should I use with these discs? A: Start with coarser grits (120–400) for plane grinding and stock removal, progress to finer grits (800–4000) for fine grinding and pre-polish stages—typically 3–5 steps depending on material and required finish.

Q: Are these discs suitable for wet grinding only? A: Yes—they are fully waterproof and perform best with water or coolant to maximize cutting efficiency, reduce heat, prevent loading, and extend disc life.

Q: Can these discs be used on automatic grinders? A: Absolutely—they are compatible with both manual and automatic metallographic grinders/polishers, including G-Hexa models, under central or individual loading.

Q: How do these compare to diamond grinding discs? A: SiC discs are more cost-effective for general-purpose grinding of a broad range of materials; diamond discs (such as GHX-GRP-CON-GRD-DIA-001) offer superior speed and life on very hard ferrous metals.

Q: What platen sizes are supported? A: Available in 8″ (200 mm), 10″ (250 mm), and 12″ (300 mm) to match common grinder platens—select the size that fits your equipment.

Q: How should the discs be stored? A: Store flat in a cool, dry place away from direct sunlight and extreme humidity to maintain adhesive performance (PSA) and prevent curling or degradation.
