Manual Grinder and Polisher GHEXA-GRP-EQP-AUT-013

The GHEXA-GRP-EQP-AUT-013 is a robust, single-disc manual grinder and polisher featuring a large 12″ (305 mm) disc, engineered for stable, high-performance preparation of large or heavy metallographic samples. Powered by a servo motor delivering consistent 10 N·m torque even at low speeds (50–600 rpm), it combines a durable 304 stainless steel body, aluminum base, large-diameter drainage, detachable faucet, worktable locking for precise manual control, and automatic temperature-sensing cooling to ensure reliability, ease of use, and long service life. Ideal for laboratories processing oversized specimens, batch work, or demanding grinding/polishing tasks in research, quality control, and industrial settings.

Specifications

Key Applications & Uses

• Manual grinding and polishing of large metallographic samples, castings, forgings, billets, extrusions, and heavy test specimens in quality control and production labs
• Preparation of flat, low-deformation surfaces on metals, alloys, ceramics, composites, and coatings for optical microscopy, hardness testing, and microstructural evaluation
• High-volume or oversized sample processing in automotive, aerospace, steel manufacturing, foundry, and heavy machinery quality assurance departments
• Precise manual control workflows requiring stable low-speed performance and worktable locking for consistent results on big or irregularly shaped pieces
• Supporting university materials engineering labs, research institutes, and contract testing facilities handling large-scale or industrial-grade specimens
• Ideal for labs needing a durable, large-disc manual system with minimal maintenance and excellent corrosion resistance in wet environments

Frequently Asked Questions (FAQs)

Q: What is the maximum disc size and sample capability of the GHEXA-GRP-EQP-AUT-013? A: It features a 12″ (305 mm) disc, providing generous surface area for large single samples, heavy test pieces, or multiple smaller specimens processed simultaneously.

Q: Does the motor perform well at low speeds? A: Yes—the servo motor delivers a constant 10 N·m torque even at 50 rpm, ideal for fine polishing or heat-sensitive materials without loss of effectiveness.

Q: How durable is the machine in wet lab conditions? A: Extremely durable—the 304 stainless steel body, aluminum base, large-diameter outlet, and automatic cooling system prevent rust, clogging, and overheating during prolonged wet grinding/polishing.

Q: What is the benefit of the worktable locking feature? A: It allows secure, precise positioning and manual pressure control, ensuring consistent results and stability when working with large, heavy, or irregularly shaped samples.

Q: How easy is cleaning and maintenance? A: Very convenient—the detachable faucet enables fast rinsing, the large Φ32 mm outlet avoids clogging, and the overall design supports quick, hassle-free upkeep.

Q: Is a recirculating water tank available? A: Yes—an optional recirculating water tank can be added for closed-loop operation, reducing water consumption and simplifying setup in labs without direct drainage.

Q: Can it handle both grinding and final polishing? A: Absolutely—the wide 50–600 rpm stepless range and high-torque motor support the full metallographic sequence, from aggressive grinding to mirror-finish polishing on large samples.
