Key Applications & Uses
- Automated grinding and polishing of metallographic samples (metals, alloys, ceramics, composites, coatings) for microscopic analysis and hardness testing
- Preparation of flat, deformation-free surfaces in quality control, failure analysis, and process validation laboratories
- High-repeatability processing of multiple samples using central or individual loading for consistent results in batch workflows
- Fine grinding and final polishing stages following rough grinding in university materials science, R&D, and industrial testing facilities
- Preparation of polished cross-sections for optical microscopy, SEM, microhardness, and layer thickness evaluation in electronics, automotive, aerospace, and manufacturing labs
- Supporting pharma (drug delivery components), biotech (biomaterials), and research environments requiring standardized, reproducible metallographic preparation
Why Choose from G-Hexa?
- Dual Loading Flexibility — Choose central pressure (high force, up to 360 N) for bulk processing or individual loading (precise 5–60 N per sample) for delicate or varied specimens—upgrade central mode for quantitative depth control.
- Programmable & Repeatable — Store and recall 20 optimized grinding/polishing recipes via the intuitive 7-inch touchscreen for fast setup, minimal training, and consistent results across operators and batches.
- Efficient & Clean Operation — Optional 4-channel peristaltic dosing ensures automatic, precise delivery of diamond suspensions; large side drainage and pluggable faucet simplify cleanup and reduce maintenance downtime.
- Durable & Safe Design — Robust cast aluminum body, SMC loading cylinders, two-hand safety controls, and built-in cooling fan provide long-term reliability and operator protection in demanding lab environments.

Frequently Asked Questions (FAQs)
Q: What platen sizes does the GHEXA-GRP-EQP-AUT-004 support? A: It accommodates 203 mm (8″), 254 mm (10″), and 305 mm (12″) platens, giving flexibility for different throughput and abrasive requirements.
Q: What is the difference between central and individual loading modes? A: Central loading applies uniform force (20–360 N) to all samples simultaneously (ideal for batch uniformity); individual loading applies precise force (5–60 N) to each sample independently (best for delicate or mixed materials).
Q: Can the machine perform quantitative grinding? A: Yes—in central loading mode, it can be upgraded for precise depth control (±0.1 mm accuracy, 0.1–10 mm range) to achieve exact material removal.
Q: What dosing options are available? A: An optional 4-channel peristaltic pump system (ADS-1, ADS-4, ADS-4S, ADS-8 variants) automatically dispenses diamond suspensions or lubricants at controlled intervals and flow rates for consistent polishing.
Q: How many samples can be prepared at once? A: Up to 10 samples in central loading (depending on holder size) or 6 samples in individual loading—various holder diameters (25.4–50 mm) are available to match your needs.
Q: Is the machine suitable for irregular or non-standard samples? A: Yes—universal, irregular, locking, and side-locking fixtures (plus leveling devices) allow secure holding of rectangular, oversized, or oddly shaped specimens up to 120 × 30 mm or 50 × 50 mm.
Q: What maintenance features simplify daily use? A: Large side drainage prevents clogging, a pluggable faucet enables quick disk cleaning, and the built-in fan reduces heat-related failures—optional recirculating tank (45 L) further supports continuous wet preparation.
