Key Applications & Uses
- High-throughput grinding and polishing of metallographic samples (steels, alloys, non-ferrous metals, ceramics, composites, coatings) for optical microscopy, SEM, and hardness testing
- Simultaneous processing on two discs (e.g., coarse grinding on one, fine polishing on the other) to accelerate workflow in quality control and production labs
- Preparation of flat, scratch-free surfaces for microstructure analysis, inclusion rating, layer thickness measurement, and failure investigation
- Batch preparation of multiple samples using central or individual loading modes for consistent, reproducible results in automotive, aerospace, electronics, and manufacturing facilities
- Fine grinding to final polishing stages in university materials science departments, research institutes, and contract testing laboratories
- Supporting pharma (medical implants), biotech (biomaterials), and advanced materials R&D requiring high surface quality and process standardization

Frequently Asked Questions (FAQs)
Q: What is the main advantage of the dual-disc design in the GHEXA-GRP-EQP-AUT-006? A: Two independent discs allow simultaneous rough grinding on one and fine polishing on the other, significantly increasing throughput and workflow efficiency in busy labs.
Q: What is the difference between the Alpha-660 and Alpha-661 variants? A: The Alpha-660 includes quantitative grinding capability (±0.1 mm accuracy, 0.1–10 mm range) in central loading mode; the Alpha-661 is the standard version without quantitative function.
Q: How many samples can be prepared at once? A: Up to 8–10 samples in central loading or 6 samples in individual loading, depending on holder size (25–50 mm diameters available).
Q: Does the machine support automatic dosing of polishing fluids? A: Yes—an optional 4-channel peristaltic pump system delivers diamond suspensions or lubricants automatically at controlled intervals and flow rates for consistent polishing.
Q: Can it handle irregular or non-round samples? A: Yes—universal, irregular, locking, and side-locking fixtures accommodate rectangular, oversized, or irregular shapes up to 120 × 30 mm or 50 × 50 mm.
Q: What maintenance features are included? A: Large-diameter side drainage prevents clogging, a detachable faucet simplifies disc cleaning, and a built-in temperature-sensing fan reduces heat-related issues—optional recirculating tank available for continuous wet operation.
Q: Is the system suitable for both grinding and final polishing? A: Absolutely—it is a complete grinder-polisher supporting the full metallographic sequence from coarse grinding to mirror-finish polishing with programmable multi-step recipes.
