Double Wheels Grinder & Polisher GHEXA-GRP-EQP-AUT-012

The GHEXA-GRP-EQP-AUT-012 is a compact, dual-disc manual grinder and polisher featuring two independent 8″ (203 mm) wheels with separate touch-panel controls, delivering professional-grade performance in a small footprint. Powered by high-torque servo motors that maintain 10 N·m even at low speeds, it offers stepless speed adjustment (50–600 rpm, up to 1000 rpm on special request), CW/CCW rotation, three preset speeds, timing/countdown function, fully sealed trays, retractable faucets, and tool-free disc removal. Ideal for space-limited laboratories, teaching environments, and moderate-throughput metallographic preparation of metals, alloys, ceramics, composites, and coatings.

Specifications

Key Applications & Uses

• Routine grinding and polishing of metallographic specimens (metals, alloys, ceramics, composites, coatings) in university teaching labs, small research groups, and quality control facilities
• Preparation of flat, deformation-free surfaces for optical microscopy, microhardness testing, and basic microstructural analysis
• Simultaneous processing on two discs (e.g., coarse grinding on one, fine polishing on the other) for moderate batch sizes or different preparation stages
• Daily sample preparation in incoming inspection, failure analysis, and process validation laboratories with limited bench space
• Supporting materials science education, entry-level R&D, pharma (material qualification), biotech (biomaterial surfaces), and industrial labs needing compact, dual-wheel capability
• Ideal for environments requiring manual control, quiet operation, and easy maintenance without compromising professional results

Why Choose from G-Hexa?

• Dual Independent Wheels — Two 203 mm discs with separate controls allow simultaneous rough and fine operations or different abrasives, maximizing efficiency in compact setups.
• Consistent Low-Speed Power — Servo motors deliver stable 10 N·m torque even at 50 rpm, ensuring smooth, effective material removal on delicate or heat-sensitive samples.
• Space-Saving & Durable — Small footprint with high-strength ABS shell, fully sealed trays to prevent water ingress, and tool-free disc changes make it perfect for bench-constrained labs.
• Intuitive Touch Operation — Tempered glass touch panels with preset speeds, stepless control, and timing/countdown simplify use for students, technicians, and experienced users alike.
• Easy Maintenance Design — Retractable faucets, large Φ32 mm outlets, and optional recirculating tank keep cleaning quick and prevent clogging or corrosion.
• Reliable G-Hexa Support — Fully compatible with G-Hexa consumables and accessories; backed by fast delivery across India, competitive pricing, and expert metallographic guidance for researchers, universities, pharma, biotech, and industrial users.

Frequently Asked Questions (FAQs)

Q: What disc sizes does the GHEXA-GRP-EQP-AUT-012 support? A: It is equipped with two 8″ (203 mm) discs as standard, providing ample surface area for small to medium samples while keeping the overall footprint compact.

Q: Can both wheels be used independently? A: Yes—each wheel has its own dedicated touch panel, allowing independent speed, direction, and timing settings for maximum flexibility.

Q: Does the machine maintain torque at low speeds? A: Yes—servo motors ensure a constant 10 N·m torque even at 50 rpm, delivering consistent performance for fine polishing or delicate materials.

Q: How easy is it to clean the working area? A: Extremely convenient—the retractable faucet allows quick rinsing, fully sealed trays prevent water leakage into the machine, and discs are removed without tools.

Q: Is it suitable for teaching or multi-user labs? A: Absolutely—its compact size, quiet operation (<50 dB), intuitive touch interface, and durable construction make it ideal for educational settings and shared laboratory spaces.

Q: What water supply is required? A: It needs a standard lab water line with max pressure <0.3 MPa (inlet G 3/4 thread, outlet Φ32 mm). An optional recirculating water tank is available for closed-loop systems.

Q: Can it handle both grinding and polishing steps? A: Yes—the wide 50–600 rpm range (extendable to 1000 rpm on request), directional control, and dual wheels support the complete metallographic sequence from coarse grinding to final polishing
